Embodiments of the present invention relate to athletic performance garments. Specifically, embodiments of the present invention relate to warp-knitted athletic performance garments having areas of differing characteristics within the same seamless panel.
Background
Physical activity is important to maintaining a healthy lifestyle and individual well-being. There are many activities in daily life that require individuals to use their strength, agility, posture, and balance, and maintaining physical fitness can help individuals complete these activities with minimum disruption to their lives. Maintaining physical fitness has also been shown to strengthen the heart, boost HDL cholesterol, aid the circulatory system, and lower blood pressure and blood fats, translating to lower risk for heart disease, heart attack, and stroke. Physical activity also strengthens muscles, increases flexibility, and promotes stronger bones, which can help prevent osteoporosis.
Performance apparel may be worn by a wearer during periods of athletic activity. For example, while running, swimming, or playing a sport. Such activity may involve substantial energy expenditure, relative movement of limbs and other body parts, and perspiration. Such motion is typically intended to be optimized to achieve a goal (e.g., running or swimming a target distance and/or speed). Performance apparel may be designed not to impede such motion, or even to enhance it. Performance apparel may also be worn after an activity, for example, to assist a wearer's muscles in recovering more quickly after exercise. Garments are known that purport to assist a user in achieving a variety of fitness goals, including increasing muscle activation in desired locations. However, existing garments often suffer from problems such as poor functionality, uncomfortable fit, high cost, and undesirable aesthetics.
At least some of the embodiments of the present invention satisfy the above needs and provide further related advantages as will be made apparent by the description that follows.
Some embodiments of the present invention provide a knitted athletic performance garment including a seamless panel to cover a portion of a wearer's body, and a first performance zone and a second performance zone formed in the seamless panel, wherein the first performance zone is formed of a first warp knit stitch construction and has a first modulus, wherein the second performance zone is formed of a second warp knit stitch construction and has a second modulus, wherein the first warp knit stitch construction is different from the second warp knit stitch construction, wherein the first modulus is different from the second modulus, and wherein the difference in modulus between the first performance zone and the second performance zone is due to the difference in stitch construction between the first performance zone and the second performance zone.
Some embodiments of the present invention provide an athletic performance garment including a knitted high-power zone having a high-power knit construction, and a knitted low-power zone having a low-power knit construction, wherein the high-power zone and low-power zone are seamlessly formed together in a flat pattern, and wherein an average underlap of the high-power zone is longer than an average underlap of the low-power zone.
Some embodiments of the present invention provide an athletic performance garment including a knitted high-power zone having a high-power knit construction, and a knitted low-power zone having a low-power knit construction, wherein the high-power zone and low-power zone are seamlessly formed together in a flat pattern, and wherein an average stitch angle of the high-power zone is smaller than an average stitch angle of the low-power zone.
Additional features of embodiments of the invention will be set forth in the description that follows, and in part will be apparent from the description, or may be learned by practice of the invention. Both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying figures, which are incorporated herein, form part of the specification and illustrate embodiments of the present invention. Together with the description, the figures further serve to explain the principles of and to enable a person skilled in the relevant arts to make and use the invention.
Embodiments of the present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings, in which like reference numerals are used to indicate identical or functionally similar elements. References to an “embodiment” indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, descriptions of embodiments do not necessarily refer to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
The following examples are illustrative, but not limiting, of the present invention. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the invention.
Performance apparel according to some embodiments of the present invention may fit a wearer in close contact with the wearer's skin, and may in some cases be worn under other apparel. In this way, the apparel can provide performance benefits to the wearer. For example, the close fit of an article of performance apparel may help minimize wind resistance, minimize flapping of apparel material, maintain proper position of the apparel relative to areas of the wearer's body, minimize uncomfortable movement of some parts of a wearer's body relative to other parts of the wearer's body, wick away perspiration, provide compressive force, and facilitate muscle movement by storing and releasing elastic energy in response to wearer motion.
In some embodiments of the present invention, performance apparel may have different performance characteristics at different zones relative to the body of a wearer. For example, performance apparel may apply relatively higher compression to relatively larger muscle groups, may apply relatively lower compression to relatively smaller muscle groups, and may provide relatively high ventilation to areas of the body that generate relatively high heat and sweat.
In some embodiments of the present invention, apparel may be formed from a number of discrete seamless textile panels joined together at seams (e.g., by fusion, gluing, sewing, stapling, or heat-bonding, usually near the edges of the panels). For instance, textile panels of different performance characteristics may be joined together at their edges to form a finished article. In some embodiments of the present invention seams are minimized in a performance apparel garment by forming the garment of seamless textile panels that themselves include multiple zones having different performance characteristics. As performance apparel may be tight fitting, minimizing seams between textile panels of different performance characteristics may help to eliminate discomfort to a wearer (e.g., from scratching or chafing due to seams). In other words, within each textile panel there may be at least two zones having different performance characteristics, with no seam therebetween. For example, a textile panel forming a portion of a garment according to an embodiment of the present invention may include no seams between zones having different performance characteristics. In this way, multiple zones having different performance characteristics may be integrally and continuously manufactured in a seamless panel, thereby simplifying garment manufacture by minimizing the number of separate panels that must be sewn or otherwise connected together to form the finished garment.
A knitted garment 100 according to an embodiment of the present invention may be constructed of a plurality of seamless panels 110. For example, knitted garment 100 as depicted in
Each seamless panel 110 may include one or a plurality of performance zones 200 having different performance characteristics (e.g., modulus, ventilation). For example, a single seamless panel 110 may include two or more of a low-power zone 210, a medium-power zone 220, a high-power zone 230, and a ventilation zone 240. In some embodiments performance zones 200 of different types may be differently-colored, and performance zones 200 of the same type may be similarly-colored (e.g., to facilitate identification of performance zone type, and/or for aesthetic purposes). The different colors may be applied to the knitted garment 100 (or a knitted garment pattern 102) by, for example, a dyeing or printing process.
Knitted garment 100 may be constructed from garment pattern 102 (see
In some embodiments, each performance zone within seamless panel 110 is continuously knitted together with other performance zones 200. In this way performance zones 200 of a seamless panel 110 are continuously formed, without seams between different performance zones 200 of the same seamless panel 110. Each seamless panel 110 may be cut from knitted garment pattern 102 along its panel edge 112. Panel edges 112 (see
To maintain textile continuity between different performance zones 200 of a seamless panel 110, a knit construction of textile fibers 114 forming seamless panel 110 may change at a transition 202 between different performance zones 200 (see, e.g.,
Different knit constructions can be formed from different basic stitch types and combinations thereof. For example, a first basic warp-knit stitch type 310 (see
In some embodiments, low-power knit construction 410 is formed entirely of textile fibers 114 forming second basic stitch type 320 (see
In some embodiments, medium-power knit construction 420 is formed of textile fibers 114 forming first basic stitch type 310 and textile fibers 114 forming second basic stitch type 320 in about a 2:1 ratio. For example, in
In some embodiments, high-power knit construction 430 is formed of textile fibers 114 forming first basic stitch type 310 and textile fibers 114 forming second basic stitch type 320 in about a 5:1 ratio. For example, in
In some embodiments, ventilation knit construction 440 is formed of textile fibers 114 forming second basic stitch type 320 and textile fibers 114 forming third basic stitch type 330 in about a 1:1 ratio. For example, in
The present invention is not limited to the particular knit constructions or combinations depicted, but can be applied to other knit constructions not explicitly described herein in some embodiments of the present invention.
Knit constructions may change at interfaces 202 between performance zones 200, and may maintain continuity of textile fibers 114 from one performance zone 200, across transition 202, to an adjacent performance zone 200, as shown, for example, in
Different basic stitches and combinations thereof may impart different performance characteristics to different performance zones 200. For example, selection of basic stitches may influence the modulus of a performance zone 200. Modulus is a measure of power in textile fabrics in the cross direction (i.e., perpendicular to the warp direction). For example, it can be characterized as tensile stress of a fabric at a selected elongation (e.g., 40% elongation). A higher modulus corresponds to higher power and compression of a performance zone 200.
In some embodiments, different basic stitches may have different underlap lengths in the lapping between wales 116. A longer straight underlap in the lapping between wales 116 may contribute to a higher modulus, thereby contributing higher power and higher compression to a performance zone 200. A shorter straight underlap in the lapping between wales 116 may contribute to a lower modulus, thereby contributing lower power and lower compression to a performance zone 200. For example, first basic stitch type 310 may have a longer underlap between wales 116 and higher modulus than second basic stitch type 320.
Further, different basic stitches may have different stitch angles. A smaller stitch angle may contribute to a higher modulus, thereby contributing higher power and higher compression to a performance zone 200. A larger stitch angle may contribute to a lower modulus, thereby contributing lower power and lower compression to a performance zone 200. For example, first basic stitch type 310 may have a smaller stitch angle and higher modulus than second basic stitch type 320.
Further, different basic stitches can be used in combination within a textile part or portion (e.g., seamless panel 110), and their ratios can affect characteristics of the textile part or portion as a function of their component properties (e.g., underlap length and angle). For example, the greater the proportion of first basic stitch type 310 to second basic stitch type 320 in a fabric part or portion, the higher the overall modulus of the fabric part or portion (and the greater its power and compression properties), all else being equal. Also for example, the greater the proportion of first basic stitch type 310 to second basic stitch type 320 in a fabric part or portion, the denser and heavier the fabric part or portion may become due to the relatively higher yarn consumption in the underlap, all else being equal.
Different performance zones 200 may include different ratios of first basic stitch type 310, second basic stitch type 320, third stitch type 330, and other stitch types to achieve desired performance characteristics. For example, low-power zone 210 may have a shorter average underlap between wales 116 than medium-power zone 220, such that medium-power zone 220 has a higher modulus than low-power zone 210. This may be attributable to a greater proportion of stitch types having a shorter underlap between wales 116 in low-power zone 210. For example, as shown in the exemplary low-power knit construction 410 of
Also for example, medium-power zone 220 may have a shorter average underlap between wales 116 than high-power zone 230, such that high-power zone 230 has a higher modulus than both low-power zone 210 and medium-power zone 220. This may be attributable to a greater proportion of stitch types having a shorter underlap between wales 116 in low-power zone 210 and medium-power zone 220 than in high-power zone 230. For example, as shown in the exemplary high-power knit construction 430 of
Also for example, low-power zone 210 may have a larger average stitch angle than medium-power zone 220, such that medium-power zone 220 has a higher modulus than low-power zone 210. This may be attributable to a greater proportion of stitch types having a larger stitch angle in low-power zone 210. Since second basic stitch angle 324 is larger than first basic stitch angle 314, the exemplary low-power knit construction 410 of
Also for example, medium-power zone 220 may have a larger average stitch angle than high-power zone 230, such that high-power zone 230 has a higher modulus than both low-power zone 210 and medium-power zone 220. This may be attributable to a greater proportion of stitch types having a larger stitch angle in low-power zone 210 and medium-power zone 220 than in high-power zone 230. Since second basic stitch angle 324 is larger than first basic stitch angle 314, low-power knit construction 410 and medium-power knit construction 420 may have lower moduli than high-power knit construction 430, due to their relatively higher proportions of second basic stitch type 320.
In some embodiments, knitted garment 100 may include one or more ventilation zones 240, to facilitate airflow and cooling of a wearer. A ventilation stitch type may be incorporated into any of the previously-described knit constructions or other knit construction. For example, a ventilation knit construction 440 may include third basic stitch type 330, which may be a ventilation stitch type. In some embodiments, third basic stitch type 330 may include no connecting underlap between wales, to facilitate airflow by avoiding airflow impedance due to underlap between wales. For example, as shown in the exemplary ventilation knit construction 440 of
Knit construction of a performance zone 200 may include a greater or lesser proportion of first basic stitch type 310 to increase or decrease, respectively, the modulus of the performance zone 200. Knit construction of a performance zone 200 may include a greater or lesser proportion of second basic stitch type 320 to decrease or increase, respectively, the modulus of the performance zone 200. Knit construction of a performance zone 200 may include a greater or lesser proportion of third basic stitch type 330 to increase or decrease, respectively, ventilation of the performance zone 200. Other stitch types may be included in knit construction of a performance zone 200 instead of or in addition to basic stitch types described herein. First basic stitch type 310 and second basis stitch type 320 are described herein in terms of their relative properties (e.g., underlap length between wales, stitch angle) as they contribute to performance characteristics of performance zones 200, and are not limited to the specific stitches depicted in the figures. Third basic stitch type 330 is described herein in terms of its ventilation properties as they contribute to ventilation of performance zones 200, and is not limited to the specific stitch depicted in the figures.
Knitted garment 100 may be designed to include various combinations of different basic stitches at various locations relative to an intended wearer's body. These combinations can be used to define areas having different properties located throughout the garment to suit the design of a garment designer (e.g., performance zones 200). For example, the designer may define stitch combinations to create a high-power, high-density, heavy-weight zone (e.g., high-power zone 230), a low-power, low-density, light-weight zone (e.g., low-power zone 210), a medium-power, medium-density, medium-weight zone (e.g., medium-power zone 220), or a high-ventilation zone (e.g., ventilation zone 240). The sizes, shapes, numbers, and types of performance zones 200 may be varied to suit the desires of a designer, and are not limited to those depicted.
The designer may define the desired garment construction including stitch types, knit constructions, and/or performance zones (including, for example, the exemplary constructions described herein), and may transfer the stitch structures for knitted garment 100 into knitting electronic files. A knitting machine may then be programmed using the knitting electronic files to knit each seamless panel 110 of knitted garment 100 seamlessly into a single piece of fabric. Each seamless panel 110 may be cut from the single piece of fabric (e.g., when laid flat, see
