Aspects herein relate to an integrally knit garment having portions formed using monofilament yarns, where the garment is lightweight and exhibits a high degree of air permeability.
Traditionally, garments that exhibit higher air permeability in certain areas of the garment rely on a panel-type construction where mesh inserts are placed where increased permeability is needed.
Illustrative aspects of the present invention are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein and wherein:
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this disclosure. Rather, the inventors have contemplated that the claimed or disclosed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated.
At a high level, aspects herein relate to an integrally knit textile and garments formed from the integrally knit textile. In aspects, the textiles and garments described herein are lightweight, exhibit moisture-management characteristics, and further exhibit a high degree of air permeability due to the yarn types and knit construction used to form the textile. In aspects, the textile is formed using a first yarn type and a second yarn type. The first yarn type comprises a terephthalate polymer. More specifically, the first yarn type comprises polyethylene terephthalate (PET), commonly known as polyester. And the second yarn type comprises a monofilament polyamide, commonly known as nylon. Use of monofilament polyamide yarns as opposed to, for instance, monofilament PET yarns contributes to a better hand feel for the textile. As well, monofilament polyamide yarns are generally stronger and more resistant to abrasion than, for example, PET yarns and are also more translucent/transparent than other yarn types. Use of monofilament polyamide yarns contributes to the textile being lightweight and also contributes to the enhanced air permeability characteristics of the textile. As well, use of monofilament polyamide yarns helps to reduce snagging as compared to, for instance, the use of multifilament polyamide yarns. Use of PET yarns contributes to the moisture-management characteristics of the textile as PET yarns generally have a lower moisture regain as compared to polyamide yarns (about 0.4% compared to about 8%). Because the PET yarns have a low moisture regain, they promote moisture wicking (by, for instance, capillary action) between the PET filaments instead of absorbing the moisture thereby helping to move moisture away from, for example, a skin surface of a wearer.
As mentioned above, the knit construction of the textile is also important for achieving the high degree of air permeability and moisture-management characteristics of the textile. In aspects, the knit construction comprises at least a first portion comprising a first percentage by weight of the first yarn type (e.g., PET yarns) and the second yarn type (e.g., monofilament polyamide yarns). The knit construction further comprises a second portion that is integrally knitted from the first portion. The second portion comprises the second yarn type and a second percentage by weight of the first yarn type, where the second percentage by weight of the first yarn type is less than the first percentage by weight of the first yarn type. One result of this knit construction is that the second portions are primarily formed from the monofilament polyamide yarns, which contributes to the high air permeability of the textile. As well, because the monofilament polyamide yarns are generally transparent/translucent, the second portions are generally transparent/translucent which provides an interesting visual aesthetic to the textile. Because the first portions comprise a greater percentage by weight of the PET yarns, the first portions may facilitate the wicking of moisture away from, for instance, the body surface of a wearer.
Continuing with respect to the knit construction of the textile and garments made therefrom, it is contemplated herein that the garment may be circular knitted (or flat knitted) to minimize or eliminate the number of seams used to form the garment. During the knitting process, the placement of the first and second portions on the resulting garment may be engineered to achieve functional benefits. For instance, the first portions in combination with the second portions may be positioned on the garment to correspond to high heat and high sweat-producing areas of the wearer. Because the first portions contribute to the moisture-management characteristics of the garment, and because the second portions contribute to the high levels of air permeability of the garment, positioning the first and second portions as described helps to cool the wearer and further helps to move moisture away from the skin surface of the wearer. In another example, the garment may be engineered to comprise one or more areas formed using the first portions without the second portions. Because the first portions are less transparent/translucent than the second portions, the first portions may be positioned on the garment to correspond to areas of the wearer needing increased modesty.
Accordingly, aspects of the present invention relate to a textile comprising at least a first surface and a second surface opposite the first surface. The first surface of the textile comprises a plurality of cells, each cell comprising a perimeter comprising a first percentage by weight of a first yarn type and a second yarn type. The plurality of cells further comprises a central region enclosed within the perimeter, the central region comprising the second yarn type and a second percentage by weight of the first yarn type, wherein the second percentage by weight of the first yarn type is less than the first percentage by weight of the first yarn type. Further, a first cell and a second cell in the plurality of cells have at least one common portion of the perimeter.
Aspects herein are additionally directed to a textile having a first surface and a second surface opposite the first surface. The first surface of the textile comprises a first portion comprising a first percentage by weight of a first yarn type and a second yarn type. The first surface further comprises a second portion comprising the second yarn type and a second percentage by weight of the first yarn type, wherein the second percentage by weight of the first yarn type is less than the first percentage by weight of the first yarn type, and wherein the first portion and the second portion integrally extend from one another.
Aspects herein are further directed to an apparel item comprising a knit textile having a first surface and a second surface opposite the first surface, the first surface of the knit textile comprising at least a first portion knitted using a second yarn type and a first percentage by weight of a first yarn type and a second portion knitted using the second yarn type and a second percentage by weight of the first yarn type. The second percentage by weight of the first yarn type in the second portion is less than the first percentage by weight of the first yarn type in the first portion. Additionally, the first portion and the second portion of the apparel item are integrally knit from one another.
Positional terms as used herein to describe a garment such as “anterior,” “posterior,” “front,” “back,” “upper,” “lower,” “inner-facing surface,” “outer-facing surface,” and the like are with respect to the garment being worn as intended and as shown and described herein by a wearer standing in an upright position.
Continuing, the term “terephthalate polymer” when describing, for example, a yarn means a yarn having filaments or fibers formed from terephthalate polymers and includes, for example, polyethylene terephthalate (PET). PET is a common thermoplastic polymer resin of the polyester family. In the context of textiles, PET is generally referred to by its common name, polyester. Additionally, “cationic dyeable PET” is a special fiber that has undergone a change during polymerization to increase its affinity to certain dyes.
The term “polyamide” when describing yarns means a yarn having filaments or fibers formed from any long-chain synthetic polyamide. In the context of textiles, synthetic polyamides are commonly referred to as nylon.
The term “continuous” as used herein means a textile having a continuous knit face without integrally formed or engineered openings. Examples would include a single jersey knit construction, a half tricot knit construction, a double jersey knit construction, and the like.
The term “multifilament yarn” as used herein means a yarn having two or more filaments within a single yarn strand while the term “monofilament” as used herein means a yarn formed from a single filament.
As well, the term “integral” as used herein means a textile having at least one textile element (e.g., yarn, thread, or filament) that extends between different areas of a textile. For instance, with respect to the textile and garments described herein, the term integrally knit may mean the textile or garment has a continuous yarn that extends through different areas of the garment. To describe this with respect to a knit construction, the term “integrally knit” may mean a textile or garment having a yarn from one or more knit courses being interlooped with one or more knit courses of another area in a portion of the garment. To describe this with respect to the first and second portions detailed above, the term “integrally knit” may mean that a yarn (e.g., a polyamide yarn) extends from the first portion into the second portion. Additionally, the knit textile as described herein may mean that the textile has different areas or portions exhibiting different properties based on the yarn type found in each area and the varying percentage by weight of the yarn type in that area. This may be opposed to a panel type construction where two or more separate materials are joined by affixing edges or surfaces by, for example, stitching, bonding, adhesives, and the like, such that there is no continuity of a yarn or textile element between the two materials.
The term “percentage by weight” of a yarn type as used herein is with respect to an area of a predetermined size. Further, when comparing the percentage by weight of a particular yarn type in two different areas, it is assumed that the two areas have the same predetermined size. Using an example, area A of a textile may comprise 50% by weight of a first yarn type and 50% by weight of a second yarn type, and area B of the textile, which is the same size as area A, may comprise 100% by weight of the first yarn type and 0% by weight of the second yarn type.
Finally, as used herein, the term “moisture regain” is the percentage of moisture a bone-dry fiber or filament will absorb from the air when at standard temperature and relative humidity.

In aspects, and as shown in
The knit construction depicted in
As described, the knit textile 100 in accordance with aspects herein is formed from two yarn types. The particular properties of each type of yarn, along with the knitted structures (e.g., first portions 102 and second portions 104) may provide the knit textile 100 with different properties. The first yarn type 106, may, for example, include a terephthalate polymer such as polyethylene terephthalate (PET) (e.g. polyester). Additionally, the PET may further include a cationic dyeable PET. In an aspect, the first yarn type 106 has a denier from about 30 denier to about 100 denier. The second yarn type 108, may, for example, include a polyamide such as a monofilament polyamide yarn and is present in both the first portion 102 and the second portions 104. The second yarn type 108 comprising the monofilament polyamide yarn has a denier (D=grams/9000 meters) from about 23 denier to about 43 denier, from about 26 denier to about 39 denier, from about 30 denier to about 25 denier, or about 33 denier. Use of fine denier monofilament polyamide yarns as described herein contributes to the knit textile 100 having a good hand.
In aspects, the PET yarns comprising the first yarn type 106 found in the first portions 102 generally provide better moisture wicking than the monofilament polyamide yarns comprising the second yarn type 108 because they have a lower moisture regain (moisture regain percentage of about 0.4%). Further, as depicted in
Continuing, in other portions of the garment, where modesty is not a critical focus, the knit textile 100 may comprise only the second yarn type 108 (i.e. the second portions 104). The use of monofilament polyamide yarns in these areas causes the areas to be somewhat translucent/transparent due to the yarns themselves being translucent/transparent. Moreover, use of monofilament yarns in the second portions 104 promotes a high level of permeability. For example, the linear integrally knit structure 114 shown in in
In the second portion 104, the percentage by weight of the first yarn type 106 (e.g. PET) is generally 0%, resulting in the second portion 104 generally comprising only the second yarn type 108 (e.g. monofilament polyamide). The second yarn type 108 provides a high level of air permeability and transparency/translucency. It is advantageous to use monofilament yarns as the second yarn type 108 as these yarns exhibit better air permeability, while maintaining a lower snagging score since there are fewer filaments available for potential snagging. This may be beneficial as using yarns with high snagging scores would be inefficient and unfavorable for the wearer, especially during physical activity. The second portions 104 comprising the second yarn type 108 may be positioned in areas of a garment that need increased ventilation. For example, the second portions 104 may be positioned in areas of the garment corresponding to high heat and/or sweat producing areas of the human body when the garment is worn. Because the second portions 104 have a higher air permeability as compared to, for instance, the first portions 102, air from the external environment may more readily enter the garment to help cool the wearer (e.g., by evaporative heat transfer) and heat produced by the wearer may more readily escape the garment further helping to keep the wearer cool.
Moving onto
Continuing, the plurality of perimeters 204 are interconnected throughout the knit textile 200 while the central regions 212 are isolated from one another throughout the knit textile 200. Each central region 212 comprises the second yarn type 208 and a second percentage by weight of the first yarn type 206. Similar to
It is contemplated that the shape of the plurality of cells 210 is generally ovoid or hexagonal. As shown in
The hexagonal knit structure 220 of the knit textile 200 is advantageous as it provides good air permeability (by, for example, use of monofilament polyamide yarns), with measurements from about 900 CFM to about 1200 CFM, from about 950 CFM to about 1150 CFM, or from about 1000 CFM to about 1100 CFM as measured using ASTM D737 standards. Air permeability may differ slightly depending on the size of the individual cells 210 in the hexagonal knit structure 220. As seen in
Turning next to
As seen in
Further, the upper-body garment 300 further comprises at least one third portion 310 that is also integrally knit from the hexagonal knit textile 304. The third portion 310 comprises a continuous knit construction that comprises the second yarn type 208 and a third percentage by weight of the first yarn type 206. The third percentage by weight of the first yarn type 206 may be greater than the second percentage by weight of the first yarn type 206 found in the central region 308. The third portion 310 also extends from the front to the back of the upper-body garment 300.
As shown, the plurality of cells 312 comprising the hexagonal knit textile 304 seen in
In
In this example, the upper-body garment 300 is sleeveless. However, it is contemplated that the upper-body garment 300 may include full sleeves, half sleeves, or any variation thereof. If the upper-body garment 300 includes sleeves, the construction of the sleeves may further comprise a knit construction similar to the third portion 310 or may comprise a knit construction similar to the hexagonal knit textile 304 comprising a plurality of cells 312. Any and all aspects, and any variation thereof are contemplated as being within aspects herein. Moreover, it is contemplated herein that the placement and position of the hexagonal knit textile 304 and the third portion 310 are examples only, and other variations are contemplated herein.
Additionally, the integrally knit construction of the upper-body garment 500 comprises a knit construction similar to that shown in
Next,
In
The location of the linear knit textile 704 and the hexagonal knit textile 702 may be based on, for instance, sweat and/or heat maps of the human body. In other words, because the linear knit textile 704 and the hexagonal knit textile 702 both exhibit high levels of air permeability as compared to, for instance, continuous knit constructions, they may be positioned where ventilation is needed most while balancing the need for modesty in certain areas, as seen in
