ARTICLE OF FOOTWEAR WITH TRANSPARENT OR TRANSLUCENT PORTIONS

TECHNICAL FIELD

Aspects herein are directed to an article of footwear comprising a knitted upper with tubular structures incorporating monofilaments and includes improved stretch properties.

BACKGROUND

Uppers for articles of footwear generally provide access to the inside through the ankle opening, which may be enlarged by moving a tongue. Further, a lacing system may be included to maintain a desired fit of the upper around the wearer's foot. Some uppers lack a movable tongue and lacing system to adjust the fit of the upper, and access to the interior of the upper is generally provided by stretching the upper at the ankle opening. Over time, as the upper is repeatedly stretched to allow the foot to be inserted into the void, the upper begins to experience undesirable, even permanent stretching and loss of elasticity, which can result in malformation of the upper. Malformation of the knitted upper results in diminished fit and support, and can decrease the useable life of the article of footwear.

Additionally, some uppers may include cables or other tensile elements extending cross an instep of the upper. However, portions of the tensile elements may be exposed, which leaves the tensile element susceptible to snagging or pulling, which will lead to malformation of the knitted upper and result in diminished fit and support.

DETAILED DESCRIPTION

Aspects herein are directed to an article of footwear having a knitted upper, a knitted upper for an article of footwear, and methods of manufacturing a knitted upper for an article of footwear, where the knitted upper includes raised tubular structures comprising transparent portions, and may include a tensile element revealed through the transparent portions. In other aspects, the raised tubular structures may include translucent portions, wherein the tensile element is revealed. The transparent or translucent portions of the raised tubular structures may be made with a monofilament yarn forming monofilament portions, and may include a tensile element revealed through the monofilament portions. The raised tubular structures include a first knit layer and a second knit layer separable from the first knit layer to form a pocket. The tensile element may be inlaid within the pocket formed by the raised tubular structures. The tensile element imparts stretch, elasticity, resiliency, and structure to the knitted upper, making it less prone to malformation, which increases the useable life of the knitted upper.

Further, the first knit layer includes a transparent or translucent portion, which may be a monofilament portion, within the raised tubular structure, which provides visibility of the tensile element. In this way, the tensile element is visible to the exterior environment while the knitted structure of the transparent or translucent portion protects the tensile element from snagging or wear from the external environment. The raised tubular structures may also include one or more multifilament portions, which may contrast with the visibility provided by the monofilament portion and provide additional protection of the tensile element.

The raised tubular structures may be separated by a knit base portion knitted with multifilament yarn. In some examples, the knit base portions may include integrally knit openings, which may help to increase stretch. An increase in stretch may be particularly useful due to a lower elasticity created by the monofilament portions.

Some aspects of the disclosure also include varied use of the raised tubular structures within an upper. The upper may have two knit zones, each having raised tubular structures. A first zone may include the tensile element in the raised tubular structures, and a second zone may include raised tubular structures without the tensile element.

As used herein, an article of footwear generally includes a sole structure secured to an upper. The article of footwear described herein may comprise a running shoe, a baseball shoe, a basketball shoe, a skateboarding shoe, a cycling shoe, an American football shoe, a tennis shoe, a global football shoe, a training shoe, a walking shoe, a hiking shoe, and the like. The concepts described herein may also be applied to other footwear types that are considered non-athletic such as dress shoes, loafers, sandals, and work boots. In addition, in aspects, the concepts described herein may also be incorporated into articles of apparel. As used herein, the article of footwear may be divided into different general regions. A forefoot region generally includes portions of the article of footwear that correspond to the toes and joints connecting the metatarsals with the phalanges. A midfoot region generally includes portions of the article of footwear corresponding with an arch area and an instep area of the foot. A heel region generally corresponds with rear portions of the foot, including the calcaneus bone. The article of footwear described herein may include a lateral side, which corresponds with an outside area of the foot (e.g., the surface that faces away from the other foot), and a medial side, which corresponds with an inside area of the foot (e.g., the surface that faces toward the other foot). The different regions and sides described above are intended to represent general areas of footwear to aid in the following discussion and are not intended to demarcate precise areas. The different regions and sides may be applied to the article of footwear as a whole, to the knitted upper, and to the sole structure.

The term “exterior surface” as used herein means a surface of the knitted upper or article of footwear that faces the external environment. In some aspects, the exterior surface may mean the outermost-facing surface of the knitted upper or article of footwear. The term “interior surface” as used herein means a surface of the knitted upper or article of footwear that faces a void for receiving the wearer's foot. In some aspects, the interior surface may mean the innermost-facing surface of the knitted upper or article of footwear.

The term “knit” as used herein to describe the knitted upper refers to a textile piece that is formed from at least one yarn that is manipulated (e.g., with a knitting machine) to form a plurality of intermeshed loops (also known as interlooping) that define courses and wales. The term “course,” as used herein, refers to a predominantly horizontal row of knit loops (in an upright textile as it is knit on the knitting machine) that is produced by adjacent needles during the same knitting cycle. The course may comprise one or more stitch types, such as a knit stitch, a missed stitch, a tuck stitch, a transfer stitch, a rib stitch, and the like, as these terms are known in the art of knitting. The term “course-wise direction” refers to a direction that is parallel to the knit courses of the textile piece. The term “wale,” as used herein, is a predominantly vertical column of intermeshed or interlooped knit loops, generally produced by the same needle at successive (but not necessarily all) courses or knitting cycles. The term “wale-wise direction” refers to a direction that is parallel to the knit wales of the textile piece.

The term “double knit construction” as used herein refers to a knit construction that is generally formed on at least two needle beds of a knitting machine (e.g., a multi-bed construction). Such multi-bed knit constructions may be characterized by two opposing faces of knit loops and/or tucks, e.g., one face of loops formed on a first needle bed, and a second face of loops formed on a second needle bed. In example aspects, the two faces may be joined by yarns that interloop with yarns in both the first face and the second face of the double knit construction. Common double knit constructions include double jersey, rib, interlock, cardigan, other “double bed” knit structures initially formed on at least two needle beds, and other knit structures having two opposing faces of knit loops or tucks, including full-gauge and less-than-full gauge variations of those structures. The term “single knit construction” as used herein refers to a knit construction generally formed on a single needle bed (e.g., a single-bed construction). Common single knit constructions include single jersey.

The term “integrally knit,” as used herein, may mean a knit textile having a yarn from one or more knit courses in a first area or zone being interlooped with one or more knit courses of another area or zone. The interlooping may be through a simple knit stitch, a tuck stitch, a held stitch, a float or miss stitch, and the like. In this way, areas or zones that are integrally knit together have a seamless transition such that they seamlessly extend from one another.

The term “integrally knit opening” refers to openings formed through an intentional knitting action (known as “engineered openings”) as opposed to the inherent spacing between yarns in a knit structure. For example, the openings may be created through transfer stitches, as is known in the art of knitting. The transfer process may include a one-needle transfer, which would result in an opening that generally extends the distance of one knit wale, but other size openings may be used.

Forming the knitted upper using a knit construction may provide advantages including, but not limited to, a particular degree of elasticity (for example, as expressed in terms of Young's modulus), breathability, bendability, strength, moisture absorption, weight, abrasion resistance, and/or a combination thereof. These characteristics may be accomplished by selecting a particular knit structure, by varying the size and tension of the knit structure, by using one or more yarns comprising a particular material (e.g., a polyester material, a relatively inelastic material, or a relatively elastic material such as elasticated yarns, which is a thermoplastic material), by selecting yarns of a particular size (e.g., denier), and/or a combination thereof. Using a knit construction may also provide desirable aesthetic characteristics by incorporating yarns having different colors, textures or other visual properties arranged in a particular pattern. The yarns themselves and/or the knit structure formed by one or more of the yarns may be varied at different locations such that the knitted upper may have different properties as described herein.

The yarns, in accordance with aspects herein, may include monofilament yarns and/or multifilament yarns formed from, for example, synthetic materials. Monofilament yarns may be made from a plastic or polymer material that is extruded to form a monofilament strand. Generally, monofilament yarns may be lightweight and have a high tensile strength, e.g., are able to sustain a large degree of stress prior to tensile failure or breaking, so as to provide a large amount or degree of resistance to stretch to the knitted upper. As described herein, some portions of the knitted upper may be formed entirely of a monofilament yarn and may provide a degree of transparency to that portion of the knitted upper. The monofilament yarns may be transparent or translucent. “Transparent” and “transparency,” as used herein with respect to a material, such as a yarn, refer to the property of materials that allows light to pass through them without significant scattering or absorption. Transparent objects permit the transmission of light waves, enabling objects to be seen clearly through them. The portion of the raised tubular structure comprising monofilament yarn may be translucent. “Translucent” and “translucency,” as used herein with respect to a material, such as a yarn, refer to the property of materials that allows some light to penetrate through them, but wherein the light is scattered or diffused. This diffusion of light results in objects being visible through them, but not as clearly defined as they would be through transparent materials. “Opaque,” as used herein with respect to a material such as a yarn, refers to the property of a material that prevents light from passing or transmitting when light strikes the surface, such that all of the light is diffused and/or absorbed.

“Transparent portions” refers to an area or region of a knitted structure that has the ability for light to completely pass through at least some of that portion. Light may pass through due to transparency of materials (e.g., transparent yarn and/or polymer material). Alternatively or additionally, transparency of a given portion of the knit structure may be visibility through openings or spacing in the knit structure between looped portions. For example, the knitted structure of the transparent portion may be formed with interlooped monofilament yarn, which has a relatively smaller diameter compared to other yarns. As such, the spacing between adjacent knitted stitches within the same course or same wale, as well as spacing between different portions of the monofilament yarn forming a single loop may be greater than if the same structure were formed with a multifilament yarn or yarn having a larger diameter, such that greater visibility may be provided. In some embodiments, a single monofilament yarn in the transparent portion may have a diameter of approximately 0.114 millimeter (mm) that may be used to form monofilament yarn. In some embodiments, a single monofilament strand may have a diameter of approximately 0.125 mm that may be used to form monofilament areas. In other embodiments, a single monofilament strand may have a diameter of approximately 0.08 mm. In other embodiments, larger diameter monofilament strands may be used to form monofilament areas. The monofilament yarn in a transparent portion may be transparent or translucent. Alternatively, the monofilament yarn may be opaque such that the visibility is due to openings within the knit structure and/or transparency of a material (e.g., thermoplastic polymer material) spanning such openings within the knit structure.

“Translucent portions” as used herein refers to an area or region of a knitted structure through which light may partially pass. Translucent portions are formed with translucent materials such as translucent yarns interlooped or otherwise integrated into the knit structure and/or translucent material (e.g., thermoplastic polymer material) spanning openings between yarns in the knit structure.

“Non-transparent portions” as used herein refers to an area or region of a knitted structure through which there is no visibility through the area or region to the human eye. The non-transparent portions may be formed with opaque materials, which may be a colored yarn. Further, non-transparent portions may be knit with a thicker yarn, such as a multifilament yarn, than the transparent or translucent portions. In some embodiments, multifilament yarns disclosed herein have a larger diameter than the monofilament yarn. Multifilament yarns include multiple filaments twisted together to form a single strand. The filaments in a multifilament yarn may be the same material or different materials. Multifilament yarn may be formed from many different materials including but not limited to polyethylene terephthalate (PET) (commonly referred to as polyester), recycled PET, elastane, and/or any other suitable material. Further, the non-transparent portions may have a greater stitch density such that any openings between the knit structures may be minimally observed by the human eye when the knit structure is in an unstretched state.

Unless indicated otherwise, all measurements provided herein are taken when the upper and/or article of footwear is at standard ambient temperature and pressure (298.15 K and 100 kPa) and is in a resting (non-tensioned) state. As used herein, the terms “substantially” and “about” mean within ±10% of an indicated value.

FIGS. 1A and 1B respectively schematically depict a medial view and a lateral view of an example article of footwear 100 having a knitted upper 110 and a sole structure 112 secured to the knitted upper 110. A biteline 105 is where the knitted upper 110 meets the sole structure 112. The knitted upper 110 includes an exterior surface 218 and an interior surface 217. The article of footwear 100 is shown in the form of an athletic shoe but other types of shoes (e.g., sandals, leisure shoes, and the like) are contemplated herein. The article of footwear 100 includes a forefoot region 114 having a toe area 115, a midfoot region 116 having a throat area 126, a heel region 118 having a heel area 119, a medial side 120, and a lateral side 122. The article of footwear 100 includes an opening 125 for receiving a wearer's foot. Although not shown, aspects herein contemplate that the article of footwear 100 may include additional elements layered on top of the knitted upper 110 including, for example, leather materials, synthetic leather materials, knitted or woven textiles, polymer skins, and the like. The additional elements may be positioned at discrete locations of the knitted upper 110 including, for example, the forefoot region 114 (e.g., a toe cap), the heel region 118 (e.g., a heel counter), and the like.

As shown in FIGS. 1A-B, the knitted upper 110 includes a plurality of raised tubular structures 130 each having a tensile element 208 incorporated therein. In aspects, raised tubular structures, e.g., like the raised tubular structures 130, can have one tensile element or multiple tensile elements incorporated therein. For example, in some aspects, a single tensile element, e.g., like tensile element 208, can be incorporated into and extend through a raised tubular structure. In some aspects, multiple tensile elements, e.g., like tensile element 208, can be incorporated into and extend through a raised tubular structure. The tensile element(s) incorporated into raised tubular structures can differ in size, material, color, shape, and/or number. For example, in some aspects, multiple tensile elements can be incorporated into a single raised tubular structure, and at least some of the multiple tensile elements can have different colors to produce a unique visual effect. In some aspects, tensile element(s) incorporated into separate raised tubular structures can differ in color to produce a unique visual effect. In aspects, tensile elements incorporated into the same or distinct raised tubular structures can differ based on other properties, e.g., diameter, denier, cross-sectional shape, reflectivity, transparency, or the like. For example, in some aspects, separate raised tubular structures can incorporate tensile elements of distinct elasticity and/or stretch-resistance to provide different containment and/or lock-down properties. In aspects, some raised tubular structures can incorporate more tensile elements than other raised tubular structures.

Looking at FIGS. 1A-1B, the tensile element 208 may have the configurations of a filament (e.g., a monofilament or multi-filament), thread, rope, webbing, cable, or chain, for example. In comparison with the yarns forming the knitted components (e.g., yarns forming the first knit layer 302 and the second knit layer 304, as described below), the thickness of tensile element 208 may be greater. In some configurations, the tensile element 208 may have a significantly greater diameter than the yarns of the knitted components.

The tensile element 208 is discussed further below, but generally the tensile element 208 may affect the geometry of the upper 110 such that the upper 110 properly fits the foot of a user and remains on the user's foot during normal use. In typical articles of footwear, a shoelace is used. Instead of a shoelace (although a shoelace may additionally be included in contemplated examples), the present example includes raised tubular structures 130 containing the tensile element 208 extending over the foot of a wearer (when the article of footwear 100 is in use). As described further herein, the tensile element 208 contained within the raised tubular structures 130 may have a particular elasticity selected for providing a comfortable fit and/or sufficient resistance to footwear removal during use of the article of footwear 100.

In some aspects, to provide a more secure and comfortable fit in the article of footwear 100, there may be multiple tensile elements 208 with varied elasticity positioned to extend over different areas of the article of footwear 100. For example, in aspects, a first raised tubular structure 130 may contain a first tensile element 208 with a first degree of elasticity and a second raised tubular structure 130 may contain a second tensile element 208 with a second degree of elasticity that is different than the first degree of elasticity. The particular elasticity of the tensile element 208 selected for the corresponding raised tubular structure 130 can help provide a more comfortable, secure fit during use of the article of footwear 100 by positioning less elastic elements in areas where more containment is desired, and more elastic elements in areas where greater stretch and comfort is desired. Further, one raised tubular structure 130 may contain more than one tensile element 208 and another raised tubular structure 130 may contain only one tensile element 208 to thereby impart desired properties in the corresponding raised tubular structures. In this sense, the number of tensile elements 208 included in each corresponding tubular structure 130 can be used to tune the comfort and fit of the article of footwear 100.

As shown, the raised tubular structures 130 may be positioned within the midfoot region 116 of the upper 110. In particularly, the raised tubular structures 130 may each extend across the throat area 126 of the upper 110. For example, each raised tubular structure 130 may extend from the biteline 105 on the lateral side 122 of the upper 110 to the biteline 105 on the medial side 120 of the upper 110. The raised tubular structures 130 may be present in one or more areas of the article of footwear 100, including the toe area 115, the throat area 126, and/or the heel area 119, or any combination thereof. The raised tubular structures 130 may be present on the medial side 120, the lateral side 122, or both the medial side 120 and the lateral side 122.

The upper 110 further includes knit base portions 140 positioned between and separating adjacent raised tubular structures 130. As illustrated in FIGS. 3 and 4A-B, the raised tubular structures 130 extend outward to a height above the knit base portions 140. Further, the raised tubular structures 130 each have a greater height or thickness than the knit base portions 140. In various examples, the knit base portions 140 are integrally knit with the raised tubular structures 130.

FIG. 2 depicts the knitted component 200 of the knitted upper 110 of FIG. 1 before being secured to the sole structure 112. In example aspects, the knitted component 200 may have a generally U-shaped configuration that is outlined by an outer perimeter edge 220, a pair of heel edges 222, and an inner edge 224. The U-shaped configuration is just one example shape of the knitted component 200, and other example shapes are contemplated herein. When incorporated into the article of footwear 100, the outer perimeter edge 220 may be positioned against the upper surface of the sole structure 112 and may be joined to a strobel in example aspects. In other aspects, the knitted upper 110 may include an underfoot portion. In this example, the article of footwear 100 may not include a strobel. In example aspects, the pair of heel edges 222 are joined to each other and extend generally vertically in the heel area 119 of the article of footwear 100. The inner edge 224 forms the opening 125 and extends forward to define the throat area 126. The knitted upper 110 includes an exterior surface 218 and an interior surface 217 of the article of footwear 100. In example aspects, the exterior surface 218 of the knitted upper 110 is formed at least partially by a first knit layer (e.g., first knit layer 302 in FIG. 3), and the interior surface 217 of the knitted upper 110 is formed by a second knit layer (e.g., second knit layer 304 in FIG. 3).

As shown in FIG. 2, the raised tubular structures 130 may extend between the perimeter edges 220 of the knitted component 200 over the throat area 126. The raised tubular structures 130 may contain the tensile element 208.

In the depicted example of FIG. 2, the tensile element 208 extends in a serpentine pattern, and therefore one continuous tensile element 208 is incorporated into the knitted component 200. The portions of the tensile element 208 that extend beyond the perimeter edge 220 of the knitted component 200, and between respective sections, are referred to herein as linking sections 252. If the tensile element 208 is inlaid during a knitting process (as discussed below), the linking sections 252 may be the result of an inlay feeder (inlaying the tensile element 208) extending beyond the perimeter edge 220 of the knitted component 200 during the knitting process (e.g., while the inlay feeder changes directions after inlaying through one raised tubular structure 130 and prior to inlaying the tensile element 208 in an adjacent raised tubular structure by moving in the opposite direction).

In some examples, one or more of the linking sections 252 may be secured (e.g., fixed) relative to the sole structure 112 and/or perimeter edge 220 such that the sections of the tensile element 208 retain a similar length, tension, etc., during use. Such securement may occur after knitting and via sewing, application of an adhesive, etc. Alternatively, the linking sections 252 may remain unfixed relative to other components such that, during use, a force/tension on one section of the tensile element 208 may be distributed to other section(s) during footwear use. This may be advantageous for reducing hot spots, providing an adaptable fit to different foot shapes, etc. As described in more detail below, the linking sections 252 may be manipulated during shoe assembly, and/or may be adjustable/customizable in an assembled article of footwear 100, such that the length of the sections of the tensile element 208 are optimized for certain footwear sizes, types, functions, etc.

In an alternate example, separate tensile elements 208 may be used, rather than one continuous tensile element 208. Each separate tensile element 208 may be inserted separately (e.g., during an inlay process), or one tensile element 208 may first be inserted (e.g., during knitting) and then cut. This may be advantageous for isolating different tensile element 208 sections from a force-distribution perspective.

The tensile element 208 may have a particular elasticity selected for providing a comfortable fit and/or sufficient resistance to footwear removal during use of the article of footwear 100. In some aspects, for example, the tensile element 208 may include a relatively elastic material (e.g., a selected amount of spandex) such that the tensile element 208 has a higher elasticity than the underlying material of the upper 110 (e.g., knitted loops) or vice versa, at least in the throat area 126. For example, the elasticity of the tensile element 208, and/or its relative tested elongation, may be at least about 20% greater than an elasticity or tested elongation of the underlying material of the upper 110 (e.g., in the throat area 126) when tested in accordance with ATSM D4964-96 (2016). More particularly, when tested in accordance with this standard, the elasticity of the tensile element 208 (tested alone) may be about 50% greater, such as about 100% greater than that of the underlying knitted component 200 of the upper 110. Although it is contemplated that, in other examples, the knitted component 200 and tensile element 208 may have relatively similar elasticities, or the knitted component 200 may have a greater elasticity). Further, the tensile element 208 may have the ability to elongate a substantial amount (e.g., up to 200% or more in some instances) while retaining relatively constant elastic properties. Thus, while an underlying knitted component 200 may have a relatively narrow range of elongation, the relatively high elongation properties of the tensile element 208 (per the above-described ASTM standard) may provide enhanced fit of the upper 110 by ensuring a relatively constant retention force for maintaining the upper 110 on a user's foot.

The tensile element 208 may extend at least partially through the remainder of the upper 110 in any suitable manner. For example, the tensile element 208 may be inserted within the raised tubular structure 130 during a knitting process, such as by utilizing an inlay process. An inlay process may include using an inlay feeder or other mechanical inlay device on a knitting machine (e.g., a combination feeder) to place the tensile element 208 between two needle beds (e.g., front and back needle beds) during a knitting process. Placing the tensile element 208 within the raised tubular structures 130 during a knitting process has various advantages, including limiting post-knitting processing steps, thereby decreasing manufacturing time and labor. Alternatively, the tensile element 208 may be fed through the raised tubular structures 130 after the knitted component 200 is formed.

The raised tubular structures 130 may include a plurality of transparent portions 210 that provide visibility to the interior of the raised tubular structures 130. As such, the tensile element 208 within the raised tubular structures 130 may be visible through the plurality of translucent portions 210 of the raised tubular structures 130. In other aspects, the raised tubular structures 130 may include a plurality of translucent portions, instead of or in addition to the transparent portions 210. As such, the tensile element 208 within the raised tubular structures 130 may be somewhat visible through the plurality of translucent portions.

In various aspects, the transparent portions 210 comprise one or more monofilament yarns and, therefore, may be referred to here as monofilament portions 210. In some aspects, the monofilament portions 210 are formed entirely of one or more monofilament yarns in that the monofilament portions 210 may exclude any multifilament yarns. Transparency or translucency of the monofilament portions 210 may be based at least partially on the transparency or translucency of the monofilament yarn forming the monofilament portions 210. Additional visibility through the monofilament portions 210 may be provided by spacing portions of the interlooped monofilament yarn(s) within the monofilament portion 210.

In some aspects, the monofilament portions 210 comprise, either entirely or partially, one or more interlooped monofilament yarns and a thermoplastic polymer material at least partially around the one or more monofilament yarns and filling in at least some of the spaces formed between interlooped portions of the one or more monofilament yarns. In this way, the monofilament portions 210 may include one or more fused areas with an unlooped thermoplastic polymer material joining interlooped monofilament yarn(s). The thermoplastic polymer material in this example may be transparent or translucent to retain visibility through the monofilament portion 210. The thermoplastic polymer material may have been melted from a portion of a yarn knit into the monofilament portion 210. For example, in some examples, the monofilament portion 210 is knitted with interlooped courses of a yarn having a core-sheath configuration where a core of a first material is surrounded by a thermoplastic polymer material having a greater melting temperature than that of the first material of the core. After knitting, heat (and, in some examples, pressure) may be applied to the monofilament portions 210 until the monofilament portion 210 reaches a temperature greater than the melting temperature of the thermoplastic polymer sheath but less than the melting-to-decomposition temperature of the core such that the thermoplastic polymer sheath may at least partially melt while the core remains intact and in an interlooped configuration. In this case, the remaining core may be considered to be at least one monofilament yarn forming the monofilament portion 210. In some aspects, the thermoplastic polymer material may melt from a solid (or single-component) monofilament that is knit with another monofilament yarn having a greater melting temperature such that application of heat may melt one monofilament but not the other. In further examples, the thermoplastic polymer material may be formed separate from the knitting process, such as with a spray or adhesive.

In some aspects, the thermoplastic polymer material is thermoplastic polyurethane (TPU), thermoplastic polyethylene (TPE) or other synthetic polymeric materials having a low melting point. In examples, the melting temperature is at about 170 degrees Celsius or less. In other examples, the melting temperature is at about 100 degrees Celsius or less or 60 degrees Celsius or less.

In some aspects, the raised tubular structures 130 also include a plurality of non-transparent portions 212, through which the tensile element 208 is not visible or at least significantly less visible compared to the transparent (e.g., monofilament) portions 210. In some aspects, the non-transparent portion 212 includes one or more multifilament yarns. Each multifilament yarn may have a smaller diameter than the diameter of the monofilament yarn forming the monofilament portions 210. Moving forward, the non-transparent portions 212 may be referred to herein as multifilament portions 212.

The raised tubular structures 130 may include multiple monofilament portions 210 along a latitudinal axis 128 of the raised tubular structure 130, where two adjacent monofilament portions 210 on the same raised tubular structure 130 are separated from each other by a multifilament portion 212. Further, the monofilament portions 210 may have a first length 211 along the latitudinal axis 128 of the raised tubular structure 130, and the multifilament portions 212 may have a second length 213 along the latitudinal axis 128 of the raised tubular structure 130, where the first length 211 of each monofilament portion 210 is greater than the second length 213 of each multifilament portion 212.

Additionally, aspects of the raised tubular structures 130 may each have a repeating pattern of the multifilament portions 212 and the monofilament portions 210. Further, the multifilament portions 212 on adjacent raised tubular structures 130 may be generally aligned. For example, the multifilament portions 212 within adjacent raised tubular structures 130 may be arranged so as to form a repeating pattern of columns extending along the longitudinal axis 129 of the knitted component 200 (which extends in a toe-heel direction). In an alternative example, the multifilament portions 212 may be offset to form a staggered arrangement. Because two adjacent monofilament portions 210 on the same raised tubular structure 130 are separated from each other by a multifilament portion 212, the monofilament portions 210 in adjacent raised tubular structures 130 may also be aligned so as to form a repeating pattern of columns extending along the longitudinal axis 129 of the knitted component or, alternatively, may be offset to form a staggered arrangement. It should be understood that other patterns and arrangements of monofilament portions 210 and multifilament portions 212 are contemplated herein.

In certain examples, monofilament portions 210 extend a greater percentage of the length of each raised tubular structure 130 along its latitudinal axis 128 compared to the multifilament portions 212. In some examples, the monofilament portions 210 form a percentage of the length of a raised tubular structure 130 that is within a range of about 70% and about 95%; in some examples, the monofilament portions 210 form a percentage of the length of the raised tubular structure 130 that is within a range of about 85% and about 90%. Remaining portions of the length of the raised tubular structure 130 may be formed from the multifilament portions 212. Generally, the greater the percentage of the raised tubular structure 130 that is formed by monofilament portions 210, the less stretch the raised tubular structure 130 will have, and the more rigid the raised tubular structure 130 will be. In this respect, a knitted upper 110 may be made more or less elastic by altering the number and/or size of monofilament portions 210. For example, the knitted upper 110 will be less rigid and more elastic when monofilament portions 210 extend along about 70% of the length of a raised tubular structure 130 compared to when monofilament portions 210 extend about 90% of the length of a raised tubular structure 130. Similarly, the knitted upper 110 will be less rigid and have more elasticity with about 10 raised tubular structures 130, each having a monofilament portion 210 compared to having about 15 raised tubular structures 130, each having a similar-sized monofilament portion 210. In some aspects, raised tubular structures 130 in different portions of the upper 110 may have different concentrations of monofilament portions 210. For example, monofilament portions 210 may form a greater percentage of the length of a raised tubular structure 130 in the forefoot region 114 than of a raised tubular structure 130 in the throat area 126, which may provide more rigidity in the forefoot region 114 while allowing relatively higher stretch in the throat area 126 for easier foot entry.

Portions of the raised tubular structure 130 that are knitted with monofilament yarn are transparent or are at least translucent, and allow the inlaid tensile element 208 to be visible relative to the exterior surface 218 of the knitted component 200. In these portions, the tensile element 208 is visible at least through the openings in the knit structure formed by monofilament yarn and may be visible through the transparent or translucent knit structure. The multifilament portions 212 of the raised tubular structure 130 that are knitted with multifilament yarn do not allow the inlaid tensile element 208 to be as visible or visible at all relative to the exterior surface 218 of the knitted component 200. In FIG. 2, the tensile element 208 is shown in dashed lines at the multifilament portions 212 of the raised tubular structure 130 to indicate they are generally hidden from view relative to the exterior surface 218 of the knitted component 200. The tensile element 208 in either the monofilament or multifilament portions 210 and 212 of the raised tubular structure 130 is not physically accessible (e.g., to grabbing) to a user from an external reference point. This is advantageous to prevent tugging or snagging of the tensile element 208 and helps maintain structure and fit of the shoe. While any suitable length may be used, in some examples, the monofilament portions 210 knitted with monofilament yarn may have a length of about 0.05 mm to about 20 mm. In an exemplary example, they may have a length of about 1 mm to about 5 mm.

FIG. 3 illustrates an enlarged view of an example of a portion of the knitted component 200. The knitted component 200 includes a first knit layer 302 and a second knit layer 304. The first and second knit layers 302 and 304 may be integrally knit together. In areas forming the raised tubular structures 130, the first knit layer 302 and the second knit layer 304 are separated from each other such that a pocket 306 is formed between the first and second knit layers 302 and 304. The tensile element 208 may be positioned within the pocket 306 between the first and second knit layers 302 and 304.

In example aspects, the raised tubular structure 130 protrudes outwardly when the knitted component 200 is incorporated into the article of footwear 100 such that the first knit layer 302 is positioned at a height 330 above the knit base portion 140. The first knit layer 302 may extend away from the second knit layer 304 at the raised tubular structure 130. Further, the first knit layer 302 may be knit with a greater quantity of courses than the second knit layer 304 at each raised tubular structure 130. The raised tubular structure 130 may be referred to as an ottoman structure.

The monofilament portions 210 may be part of the first knit layer 302 such that the visibility to the tensile element 208 may be provided to someone looking at an exterior of the upper 110. Note that the monofilament portions 210 in FIGS. 3 and 5 (as well as monofilament portions 611 in FIG. 7) are schematically depicted as having a relatively open texture, and it should be understood that these monofilament portions 210 are knit such that the monofilament portions include interlooped courses of a monofilament yarn. While the first knit layer 302 may include both monofilament portions 210 and multifilament portions 212, some aspects of the second knit layer 304 do not have any monofilament portions that are formed with only monofilament yarn(s). While some aspects of the second knit layer 304 may include one or more monofilament yarns interlooped with multifilament yarns, other aspects include only multifilament yarns in the second knit layer 304.

Some aspects of the second knit layer 304 may include an elastic yarn, specifically a yarn comprising elastane. In one aspect, an elastic yarn is knit within the second knit layer 304 at only the knit base portions 140 located between the raised tubular structures 130. In other aspects, the entire second knit layer 304, including areas forming the raised tubular structures 130 include elastic yarn. The elastic yarn may be knit with another yarn such as a polyester yarn. It should be understood that the second knit layer 304 may include various combinations of monofilament yarns, multifilament yarns without elastic, and elastic multifilament yarns.

The knit base portions 140 separate the raised tubular structures 130 of the knitted component 200. The knit base portions 140 may include the first knit layer 302 and the second knit layer 304 in generally planar configurations. The first knit layer 302 and the second knit layer 304 include at least one multifilament yarn forming courses along the length of the knit base portion 140. In other words, in various aspects, the knit base portions 140 do not include any monofilament-only areas. Further, in one example, at least the first knit layer 302 of the knit base portions 140 may comprise only multifilament yarn(s) (e.g., may be formed entirely of multifilament yarn[s]).

As depicted, the knit base portions 140 may include a plurality of integrally knit openings 215. These openings impart breathability to the knitted upper 110. Additionally, the integrally knit openings 215 may increase stretchability, which may be particularly advantageous when incorporating areas with only monofilament yarns (e.g., monofilament portions 210), as monofilaments may reduce stretch.

Each opening within the plurality of integrally knit openings 215 is generally formed by knitting consecutive knit stitches using one or more yarns, executing a needle transfer (e.g., a single-needle transfer or a two-needle transfer), and then knitting consecutive knit stitches using the yarns. The knit pattern is repeated within a particular knit course. The result is a repeating pattern of the first plurality of integrally knit openings 215 within a knit base portion 140. Multiple knit base portions 140, which may be adjacent knit base portions 140, may each include integrally knit openings 215. In this way, the plurality of integrally knit openings 215 may be arranged in a repeating pattern of rows (each row corresponding to a knit base portion 140) extending parallel to the longitudinal axis 129 of the raised tubular structure 130. Further, in some aspects, the integrally knit openings 215 are offset from others in adjacent knit base portions 140 to form a staggered arrangement. Alternatively, the individual integrally knit openings 215 may be aligned among the knit base portions 140 so that the integrally knit openings 215 form aligned columns extending along the longitudinal axis 129 of the knitted component 200. In some aspects, each of the plurality of integrally knit openings 215 have a uniform size, while in other aspects, the size may vary.

FIGS. 4A and 4B depict schematic cross-sectional views of example double knit constructions that may be used in the knitted component 200 and are provided to illustrate how the tensile elements 208 are substantially contained between the first knit layer 302 and the second knit layer 304. Specifically, FIGS. 4A and 4B provide a cross-sectional view that may be taken at cutline 4A-B in FIG. 3 in accordance with aspects herein. FIGS. 4A and 4B depict raised tubular structures 130 with generally the same structure but depict different example configurations for the knit base portion 140, as described further herein.

The raised tubular structure 130 in both FIGS. 4A and 4B may be formed by a multilayer knit structure, which may be formed by a tubular knitting process where a first knit layer 302 formed on a first bed of the knitting machine remains separable from (e.g., having a central area not locked to) a second knit layer 304 formed on a second needle bed for a plurality of courses. For example, a first knit layer 302 of the raised tubular structure 130, which may define the exterior surface 218 of the knitted component 200, may be formed on a first needle bed of a knitting machine (e.g., with a single-jersey or similar knit structure). A second knit layer 304 of the raised tubular structure 130, which may define an interior surface 217 of the knitted component 200, may be formed on a second needle bed of the knitting machine (e.g., with a single-jersey or similar knit structure). Forming the first and second knit layers 302 and 304 on separate needle beds results in separation between the first and second knit layers 302 and 304, which may create a pocket 306 (which may also be referred to herein as a tunnel or channel) for receiving the tensile element 208. The pocket 306 may be closed off along the side edges 320 and 322 of the raised tubular structure 130 (which extends along the tubular structure's length). The side edges 320 and 322 may each include a course with at least one yarn (e.g., multifilament yarn) knit on both needle beds, thus locking the first knit layer 302 and the second knit layer 304 together.

Notably, the first knit layer 302 and the second knit layer 304 may each comprise a quantity of single-jersey knit courses such that the raised tubular structure 130 is large enough to receive the tensile element 208. For example, each of the first knit layer 302 and the second knit layer 304 may include at least 3 consecutive courses, such as at least 5 consecutive courses. More courses (e.g., 10 consecutive courses or more) may be used when a larger tensile element 208 is utilized. While the first knit layer 302 and the second knit layer 304 may have the same number of courses, they may alternatively include a different number of courses and/or otherwise be differently sized (as shown in FIGS. 4A and 4B), which may cause the tensile element 208 to have an offset orientation relative to a plane centralized between the opposite faces of the knitted component 200. For example, the first knit layer 302 may be formed from a greater quantity of knit courses than the second knit layer 304, which may form the dome shape of the raised tubular structure 130 (e.g., the first knit layer 302 may protrude farther than the second knit layer 304) as shown in FIGS. 4A and 4B.

Each raised tubular structure 130 includes a first side 316 and a second side 318, each extending along the latitudinal axis 128 of the raised tubular structure 130. In some examples, the first knit layer 302 of the raised tubular structure 130 includes a first side multifilament portion 312 generally on the first side 316 and a second side multifilament portion 314 generally on the second side 318, each comprised of a multifilament yarn. In some aspects, the first side and second side multifilament portions 312 and 314 are each formed with only multifilament yarn(s) in that they are not formed with a monofilament yarn. In some aspects, at locations along the raised tubular structure 130 where the first knit layer 302 includes a monofilament portion 210, the monofilament portion 210 may separate the first side multifilament portion 312 and the second side multifilament portion 314. In this way, the monofilament portion 210, which is transparent or at least translucent, may form a top “window” into the pocket 306 of the raised tubular structure 130, while the sides of the raised tubular structures 130 may have more obstructed (or completely obstructed), or less transparent (or non-transparent) views.

In other aspects, the first side 316 and the second side 318 may each comprise a monofilament yarn. In this way, the first and the second sides 316 and 318 of the raised tubular structure 130 may be comprised of monofilament yarn, forming a “window” on the first side 316 and the second side 318 into the pocket 306 of the raised tubular structure 130, while at least some of the top of the raised tubular structure 130 comprises a multifilament portion 314 to provide a partially obstructed (or completely obstructed) view along at least some areas of the top of the raised tubular structure 130. Further, in other aspects, only one of the first side 316 or the second side 318 may comprise a monofilament yarn. In this way, one side of the raised tubular structure 130 may be comprised of monofilament yarn, forming a “window” into the pocket 306 of the raised tubular structure 130, while the other side of the raised tubular structure 130 may comprise a multifilament portion 314 that provides a partially obstructed (or in some cases, completely obstructed) view. In this aspect, the “window” into the raised tubular structure 130 can be made larger by also forming the adjacent top portion of the raised tubular structure 130 with monofilament yarn. Alternatively, the top portion of the raised tubular structure 130 that is adjacent the monofilament “window” on either the first side 316 or the second side 318 may comprise multifilament yarn. It should be understood that further combinations of monofilament portions 210 and multifilament portions 314 are contemplated herein. In some aspects, raised tubular structures 130 in one or more areas of the article of footwear 100 may include a monofilament yarn, e.g., forming a “window” into the pocket 306 of the raised tubular structure 130, while raised tubular structures 130 in other areas of the article of footwear 100 may not include monofilament yarn. Any and all combinations of such raised tubular structures are contemplated herein.

In some aspects, a knitted component, e.g., incorporated into an upper, an article of footwear, or an article of apparel, can include raised tubular structures, and can include transparent or translucent yarns, materials, and/or windows that are incorporated into some or into all of the raised tubular structures according to different aspects contemplated herein.

The quantity of courses of multifilament yarn forming the first side multifilament portion 312 may be within a range of about 3 courses and about 10 courses in some examples, and within a range of about 5 courses and about 8 courses in some examples. The quantity of courses of monofilament yarn forming the monofilament portion 210 may be within a range of about 1 course and about 7 courses in some examples, and within a range of about 3 courses and about 5 courses in some examples. The second side multifilament portion 314 may be formed with the same quantity of courses of multifilament yarn as the first side multifilament portion 312 or with a different quantity of courses, which may result in an offset position of the monofilament portion 210 between the first side and the second side multifilament portions 312 and 314.

In some examples, such as the example shown in FIG. 4A, the first knit layer 302 is interlocked with the second knit layer 304 throughout the length of the knit base portion 140, therefore making the first knit layer 302 and the second knit layer 304 inseparable. For example, the yarn (e.g., multifilament yarn) forming the first knit layer 302 and the second knit layer 304 may intermittently move between needle beds during knitting, such that yarn forming loops of the first knit layer 302 in one section of a course of the knit base portion 140 also forms a different section of the same course of the second knit layer 304 within the knit base portion 140 and vice versa. In this way, the first and second knit layers 302 and 304 are secured together so that they are not separable within the knit base portion 140. Further, interlocking the first and second knit layers 302 and 304 may result in additional stretch to the knitted component 200, which may be particularly advantageous in aspects with monofilament portions 210, which may otherwise reduce stretch. Generally, the greater density of interlock stitches (where yarns on the first and second needle beds change needle beds), the greater mechanical stretch there may be. In some examples, the knit base portion 140 is knit with a 1×1 interlock, where a yarn is knit on the front bed for one needle, moved to the back bed and knit for one needle, and then moved back to the front bed for one needle, and so on. It is contemplated that other patterns may be used, such as a 1×2, 2×1, or 2×2 interlock pattern.

In an alternative example depicted in FIG. 4B, the first knit layer 302 and the second knit layer 304 are knitted together directly adjacent to the first side 316 of the raised tubular structure 130 to form the first side edge 320 and directly adjacent to a second side 318 of the raised tubular structure 130 to form the second side edge 322, but the first and second knit layers 302 and 304 may otherwise remain separable along a separable portion 404 of the knit base portion 140. A pocket 406 may be formed between the first and second knit layers 302 and 304 along the separable portion 404. Although separable, the first knit layer 302 and the second knit layer 304 may be in contact with each other within the separable portion 404 of the knit base portion 140.

FIG. 5 depicts an alternative configuration for the knitted component 200. In this configuration, the knit base portions 140 include a monofilament portion 502 on at least the first knit layer 302. The monofilament portion 502 is formed entirely of one or more monofilament yarns and does not include any multifilament yarns. The monofilament yarn used to form the monofilament portion 502 may be the same yarn used to form monofilament portions 210 on the raised tubular structures 130. In some aspects, a monofilament portion 502 of a knit base portion 140 has a longer length than a monofilament portion 210 of a raised tubular structure 130, and in some aspects, the monofilament portion 502 extends for all or substantially all of the entire length of the knit base portion 140. In some aspects, the monofilament portion 502 is centered within the knit base portion 140 between adjacent raised tubular structures 130. The knit base portion 140 may include multifilament portions 504 and 506 abutting the two adjacent raised tubular structures 130, where the monofilament portion 502 of the knit base portion 140 may be positioned between multifilament portions 504 and 506. Aspects of the knit base portion 140 may also include integrally knit openings 215, which may be in either or both of the multifilament portions 504 and 506 of the knit base portion 140.

FIG. 6 depicts a knitted component 600 that may be formed in an upper for an article of footwear having similar features described for the upper 110 of the article of footwear 100. The knitted component 600 includes zones with raised tubular structures 630 having different features. A first zone 624 includes raised tubular structures 630 separated by knit base portions 640. The raised tubular structures 630 may include a tensile element 608 positioned between two knit layers, while being alternatively visible and hidden from view due to alternating monofilament portions 610 and multifilament portions 612 along the raised tubular structures 630. The raised tubular structures 630 of the first zone 624 may be any of the examples of the raised tubular structures 130 of FIGS. 1A-5, and for conciseness, those details are not repeated here.

A second zone 626 includes raised tubular structures 631 that may also be formed with two knit layers. FIG. 7 provides an enlarged view of these raised tubular structures 631. A first knit layer 602 is positioned over a second knit layer 604, and at the raised tubular structures 631, the first and second knit layers 602 and 604 are separated from one another so as to form a pocket 606. The first knit layer 602 may extend away from the second knit layer 604 at these locations such that the raised structure of the raised tubular structures 631 may be similar to the structure described for the raised tubular structures 130. Additionally, similar to example knit base portions 140 in FIGS. 1A-5, knit base portions 641 separate the raised tubular structures 631 and may include the first knit layer 602 and the second knit layer 604 in generally planar configurations.

One difference between the raised tubular structures 631 of the second zone 626 compared to the raised tubular structures 630 of the first zone 624 is that the raised tubular structures 631 of the second zone 626 may be formed entirely of multifilament yarns. In this aspect, the pocket 606 of the raised tubular structure 631 would not be as visible in the second zone 626 as it is through the monofilament portion 210 of the raised tubular structures 630 of the first zone 624. Therefore, if a tensile element such as tensile element 608 is inlaid within the pocket 606 of the raised tubular structure 631 in the second zone 626, the tensile element 608 may not be visible through raised tubular structures 631 comprising multifilament yarn. Further, in some aspects, the raised tubular structures 631 of the second zone 626 do not include a tensile element, like tensile element 608. In this way, the raised tubular structures 631 may be hollow.

Another difference between the first zone 624 and the second zone 626 is that the first knit layer 602 within the knit base portions 641 includes a monofilament portion 611 formed entirely from a monofilament yarn, which may be the same monofilament yarn forming the monofilament portions 610 of the first zone 624. In contrast to the monofilament portions 610 of the raised tubular structures 630 in the first zone 624, which are relatively shorter in length as they are broken up by multifilament portions 612, the monofilament portions 611 of the knit base portions 641 may extend all or substantially all of the entire length of the knit base portions 641. In this way, the knit base portions 641 of the second zone 626 may each have a single monofilament portion 611, where each raised tubular structure 630 of the first zone 624 may have multiple monofilament portions 610 spaced apart by multifilament portions 612.

As multifilament portions 612 provide more stretch than monofilament portions 610 or 611, the first zone 624 may have more stretch than the second zone 626, where monofilament portions 610 are not separate from each other by multifilament yarn within a single knit base portion 641. The first zone 624 as described herein may form a throat area 126 in a midfoot region (which may correspond to midfoot region 116 of FIGS. 1A and 1B). In some aspects, the second zone 626 may form a forefoot region (which may correspond to forefoot region 114 of FIGS. 1A and 1B). Additionally or alternatively, the knitted component 600 may include a third zone 627 also having the same raised tubular structures 631 separated by knit base portions 641, as is present in the second zone 626. The third zone 627 may be positioned between the first zone 624 and an ankle opening 625, and the first zone 624 may separate the second zone 626 and the third zone 627. As depicted in FIG. 6, the third zone 627 may also include a non-tubular portion 628 of the knitted component 600 located in a central area between two groupings of raised tubular structures 631, which may increase stretch for ease of foot entry and may increase comfort. In example aspects, the first zone 624, the second zone 626 and, optionally, the third zone 627 may be integrally knit together.

The aspects described herein can be formed with a single-layer knitted structure or can be formed with a double layer knitted structure.

In some aspects herein, a knitted component, upper, article of footwear, or article of apparel can be formed with a double layer knitted structure with one or more raised tubular structures each having at least one tensile element incorporated therein that is at least partially visible through part of the raised tubular structure. In aspects, such knitted structures can be a double jersey knit structure.

In some aspects herein, a knitted component, upper, article of footwear, or article of apparel can be formed with a single layer knitted structure that includes at least one tensile element incorporated therein that is at least partially visible through part of the single layer knitted structure. For example, the single layer knitted structure can be manipulated to form a tubular-like enclosure around the tensile element(s) with transparent or partially transparent portions positioned on the tubular-like enclosure, as described herein. In aspects, such knitted structures can be a single jersey knit structure.
