[0004] The subject matter of the present invention is described with specificity herein to satisfy statutory requirements. However, this description itself is not intended to limit the scope of the disclosure. Rather, the inventors do not believe that the subject matter claimed or disclosed is in accordance with any other current or future art. In combination with the techniques, different steps or sets of steps similar to those described herein may be used. It is intended that the invention may be embodied in other ways, including combinations thereof. The terms "step" and / or "block" are used herein as used herein. may be used to identify different elements of the methodology to be adopted, but Unless the order of steps is explicitly stated, any of the various The present invention should not be construed as implying any particular steps or order between steps. .

[0005] Various articles, including footwear, are made of textiles, which are often made of yarn. A yarn or a number of yarns are interlooped (e.g., knitted) together to form a In particular, footwear uppers may be made from knitted fabrics. Or non-fabric components are added to the fabric to improve water resistance. For example, polyurethane (e.g., cross-linked polyurethane) , synthetic leather fabric, or laminated film layer can be used as a durable covering layer. However, adding any additional layers, even films, This reduces the ability of the article to conform to the wearer and provide proprioceptive feedback, which may be due to certain This can be particularly important for items in sporting activities, e.g. football shoes. The fabric allows the wearer to feel the ball through the fabric, improving ball control and ball It is important to have a certain level of traction or grip for ball handling. If the footwear has too much grip it can hinder the wearer's ability to make quick touches and ball handling. In addition, different parts of the footwear are used for different types of movements. Therefore, it is possible to create an app that has different characteristics (e.g., patterns) in different parts. Fabric for the upper may be desired.

[0006] As described in more detail below, gripping or pulling for object (e.g., ball) control The attraction is achieved by an alternating pattern of first and second regions having varying grip. These alternating patterns are designed to allow the ball contacts to be adjusted so that the desired amount of grip is achieved. For example, the knitted components or footwear uppers may be used to fine-tune the control of the The fabrics described herein include a first region having a first coefficient of friction and a second region having a first coefficient of friction. The first and second regions have a second coefficient of friction that is different or lower than the first coefficient of friction. The first region and the second region on the surface of the footwear upper may include a turn. and alternating between the first and second surfaces provides interaction between the footwear upper and an object such as a ball; The feeling of control by the wearer of the footwear upper can be enhanced. The pattern has an alternating pattern of first and second regions, the first region being a part of the upper of the footwear (e.g. For example, 40% to 80% of the total surface area of ​​the outward facing surface of the footwear upper (ball contact area) The surface of the upper of the footwear allows for a potentially enhanced sense of control by the wearer. It is assumed that this is effective in creating

[0007] Thermoplastic elastomers provide abrasion resistance, traction (also called grip), or both. The present invention can be incorporated into polymeric compositions that provide a high level of It has been confirmed that the material is suitable for use in articles where wear resistance or traction is desired, such as In many cases, the wear resistance, traction or other properties that these polymeric compositions provide are Both levels are consistent with standard vulcanized rubber used in the manufacture of footwear, apparel and sporting goods. Unlike vulcanized rubber, these polymeric compositions are thermoplastic. Its plastic properties and properties in the solid and molten state allow it to be used in industrial knitting or weaving machines. The resulting coated yarn can be easily formed into a coated yarn having properties suitable for These properties make it possible to fabricate products using conventional techniques such as knitting and weaving. The manufacturing process, as well as an industrial-scale process for producing nonwoven fabrics, is used to produce a variety of This results in a yarn that can be easily incorporated into articles. Also, unlike vulcanized rubber, this These fabrics and articles incorporating these fabrics, in turn, are made of coated yarns. The polymeric composition can be thermoformed in a manner that reflows the polymeric composition and can be applied to other components of a fabric or article. , e.g., under conditions that do not damage other yarns, other fabrics, foams, molded resin components, etc. , to provide abrasion resistant or high grip surfaces to fabrics or articles.

[0008] At a high level, various aspects of the present disclosure aim to provide certain benefits, such as ball control and durability. These thermoplastic elastomers are incorporated into the fabric of the article to maximize the desired functionality. Specifically, the knitted component includes a first core yarn (referred to herein as a (also referred to as the "core") and a first coating (referred to herein as the "coat") of a thermoplastic elastomer. The first yarn may include a first yarn having a thermoplastic composition. The article comprises one or more thermoplastic elastomers at least partially surrounding a first core yarn. The knitted component further includes a second yarn different from the first yarn. A first surface of the knitted component (e.g., facing outwardly of an article formed using the knitted component) On the surface, a first region is formed of a first yarn, while a second region is formed of a second yarn. Due at least in part to the material of the first and second yarns, The first region and the second region have different coefficients of friction with respect to a common material. The first region has a higher coefficient of friction than the second region, and the first region has a higher coefficient of friction than the second region. For example, the first area may have the same ball grip as the second area. The coefficient of friction between the ball surface and the ball head may be higher than the coefficient of friction between the ball surface and the ball head. The first and second regions form an alternating pattern, and the first region is in contact with a first surface (e.g., a footwear surface). The upper's ball-contacting surface area should account for 40% to 80% of the total surface area. An improved level of grip can be imparted to the knitted component.

[0009] When the knitted component is incorporated into an upper for footwear such as a football shoe, The alternating pattern of the first and second regions not only provides wear resistance but also improves ball control. In some embodiments, alternating putters can improve the player's control and ball handling. The pattern may be a concentric pattern on the medial surface of the upper (e.g., between the first region and the second region). In some embodiments, the first and second regions comprise stripes ( For example, a linear boundary between a first area and a second area) to form an alternating pattern of different In one example, the stripes may be generally along the bite line, such as the outer side of the upper. The first and second regions of the inner side of the putter extend from the center to the throat. While this may be desirable for passing, receiving and kicking the ball, For dragging or nudging, a more linear pattern on the outer flank is desired. obtain.

[0010] Further, in some embodiments, the knitted component has a first coating flowing therethrough and a second coating flowing therethrough. Occupying at least a portion of the space between the first yarn course or the first core yarn course This arrangement advantageously eliminates the need for a laminated skin. Integrating 360-degree ball control directly into the knitted components without The surface can be simplified as a single functional layer. When used in ball boot uppers, this single functional layer is made up of a single functional layer. The elimination of layers helps bring the wearer closer to the ball, which reduces adhesion to the wearer. This increases the receptive feedback, further improving ball control. By not including a knitted outer skin, post-knitting processes are reduced, improving manufacturing efficiency. To rise.

It should be understood that a mirror image of the intended footwear 100 may also be applied.

[0020] In some embodiments, footwear 100 includes a sole structure 104 and an upper 102. The shoe structure 104 is secured to the upper 102 and is in contact with the foot and the ground when the footwear 100 is worn. In some embodiments, the sole structure 104 extends between the midsole 107 and the outer sole 108. The midsole 107 includes an abrasion resistant sole 109. The midsole 107 is made of an abrasion resistant material such as Strobel (not shown). The upper 102 may be secured to a lower region thereof and may be made of a resilient material such as a polymer foam or It may also include cushioning elements constructed of other suitable materials.

The traction elements may be separate elements affixed to the outsole 109. Alternatively, it may be formed integrally with the outsole 109.

[0021] The upper 102 is made up of various elements (e.g., lace stays, tongue collar, medial side, lateral side, It is made up of the sides, vamp, toe box, and heel counter. Combined together, these provide a structure that securely and comfortably accommodates the foot. Although the configuration of the sole structure 104 may vary significantly, the various elements are generally The space in the upper 102 is determined to receive and fix the foot. The intermediate surface is shaped to accommodate the foot and is contoured to the medial and lateral sides of the foot over the instep and toe areas. The inflatable shoe may extend along the side of the foot, under the foot and around the heel area of ​​the foot.

[0022] At least a portion of the upper 102 may be knitted, for example, by a flat knitting process or a warp knitting process on a flat knitting machine. or the like. The element 130 may be knitted using a knitting process such as weft knitting, warp knitting, or any other suitable knitting process. The molded article may be formed as a single, integral, one-piece element during the molding process. In the depicted example, knitted component 130 forms the outer sheath of upper 102. A lateral midfoot region 114a, a medial midfoot region 114b, and a forefoot region 114c of the upper 102. 116 and at least a portion of the exterior of the throat region 126. In addition, knitted component 130 further forms the inner surface of upper 102.

[0023] The upper 102 may further be a knit, woven, nonwoven, or other type of fabric. The fabric may include one or more additional components, such as a fabric component 140. The substrate 140 forms at least a portion of the heel region 118, the ankle collar region 112, and the tongue 124. The fabric component 140 may be a single fabric component, or may be formed by fastening together multiple fabric components.

Alternatively, the fabric component 140 may be sewn, The stent may be secured to knitted component 130 via at least one adhesive or the like.

[0024] Knitted component 130 may be of one or more different types to provide different functionality. For example, knitted component 130 may include a first yarn and a second yarn. The first yarn (herein referred to as the first coated yarn) may include a The coated yarn (also called coated yarn) is made of a first core yarn and a first yarn and a first coating that provides a first set of properties to the second yarn. For example, the second yarn may have a different material composition than the first yarn. The first coating of the first yarn is applied so that the second yarn exhibits different properties than the first yarn. The coating may include a different coating than the coating.

[0025] Further, within the first yarn, the first core yarn and the first coating are different The materials may have different compositions to provide different properties. For example, Thus, the first coating may be comprised of a low processing temperature polymeric composition, while the second The first core yarn melts or deforms at a temperature at which the first coating leaves the core yarn intact. In one embodiment, the first yarn may be made of a high processing temperature polymeric composition. The deformation temperature of the polymer composition of the core yarn in the first coating is , for example at least 20° C. higher than the melting temperature of the polymeric composition comprising the thermoplastic composition. This allows the core yarn to be coated with the coating while the coating is in a molten state. It can be coated with

[0026] The first core yarn in the first yarn is a monofilament or a multifilament. The yarn, e.g., the yarn has sufficient properties to be operated on an industrial-scale knitting machine (Denny The material is made of commercially available polyester or polyamide yarns with properties such as elasticity and tackiness. Furthermore, the core yarn may be made of polyester, high tenacity polyester, or polyamide yarn. , metal yarn, stretch yarn, carbon yarn, glass yarn, polyethylene or Polyolefin yarn, bicomponent yarn, PTFE yarn, ultra-high molecular weight poly Ethylene (UHMWPE) Yarn, Liquid Crystal Polymer Yarn, Special Decorative Yarn, Reflective Yarn or natural or multicomponent yarns made of one or more of these yarns. The core yarn may be based on synthetic fibers. In an exemplary embodiment, the core yarn is polyester. The thermoplastic material comprises:

[0027] In various embodiments, the first core yarn is braided by any method known in the art. In one embodiment, the high performance coating for the first coating disclosed herein can be used. The polymer composition may be pultruded and / or pulled through a bath of liquid polymeric material. In yet another embodiment, the coating process is not required. The garment material may be knitted in various configurations, either alone or with one or more other yarns, and then thermoformed; Upon reflow and resolidification, the coating material (e.g., polymers containing thermoplastic elastomers) The child composition may be formed on one or more surfaces, depending on the arrangement of the first yarn within the knit structure, and and / or the first core yarn to form a structure having an appropriate concentration of coating material within the first core yarn.

[0028] The first coating on the first yarn is a thermoplastic composition including a thermoplastic elastomer. The polymer composition includes a thermoplastic elastomer composition. It is possible to form fibers, filaments, yarns or films directly from the polymeric composition. However, due to their elastomeric properties, these forms of polymeric compositions are not suitable for high levels of That is, the fiber, filament, yarn or film has a certain degree of stretch and thermal shrinkage. They tend to stretch around the guides in the machine rather than sliding through them, making them difficult to manufacture on an industrial scale. It tends to shrink at temperatures commonly encountered in weaving machines and looms. By applying the polymeric composition as a coating to a core yarn suitable for making The resulting coated first yarn retains the tenacity and stretch resistance of the core yarn. On the other hand, the elastomeric properties of the coating make it possible to overcome the advantages offered by the polymeric composition of the coating. It also provides an outer surface with good traction and abrasion resistance. For example, the tensile strength at break is at least 1 kilogram or more, with a strain to break of less than 20 percent and a heat shrinkage of 20 percent or less. The 150 denier core yarn, which is less than 1.0 mm in diameter, has a nominal average outer diameter of about 1.0 mm. The ability to be knitted or fitted using a commercially available flat knitting machine, even when coated with a polymeric composition up to the diameter It has been found that the yarn can be used in industrial scale equipment. Therefore, this first yarn is more dense in both location and quantity compared to conventional manufacturing processes. Various placements of polymeric compositions within fabrics and articles comprising fabrics with a high level of specificity. This may also enable new manufacturing methods that allow

[0029] Furthermore, due to the thermoplastic nature of the polymeric composition, the melting temperature of the polymeric composition is The composition is melted to coat the first core yarn when the temperature is sufficiently lower than the deformation temperature of the yarn. and subsequently thermoforming knitted component 130 to form a a first core yarn; and a reflowed and resolidified polymeric composition that solidifies the first core yarn. In one embodiment, the coating is a thermoformed network that is made up of both the coating and the thermoformed network. The thermoplastic elastomer of the polymer composition of the present invention has a glass transition temperature of less than -20°C. This allows the polymeric composition to remain stable even when the knitted component 130 is used in low temperature environments. The thermoplastic elastomer present therein is allowed to be in a "rubbery" state. In the coating, the polymer composition has a melting temperature of at least 100° C. This allows the polymeric composition to be In another embodiment, the polymer composition of the coating can be prevented from melting. The temperature is at least 130° C., which means that knitted component 130 is not subject to a steaming process or the like. Such conditions that fabrics are often encountered during the manufacturing process of articles of footwear, apparel or sporting goods, In another embodiment, the polymer composition is provided to ensure that the polymer composition does not melt when exposed to heat. The polymer composition of the coating has a melting temperature of less than 170°C, which allows the knit construction Element 130 is not intended to adversely affect other fabrics or components that may form part of upper 102. In another embodiment, the high molecular weight of the coating is ensured to be able to be thermoformed at temperatures that are not possible with conventional coatings. The enthalpy of fusion of the thermoplastic elastomer of the composition is less than about 30 Joules / gram or may be less than 25 Joules per gram, which is a function of the strength of the polymeric composition during the thermoforming process. 2. Melt the material completely and achieve good flow of the molten polymeric composition to form the knitted component. Less heat and shorter heating times are required to better consolidate the 130 yarn network. In another embodiment, the polymeric composition of the coating is The recrystallization temperature of the thermoplastic elastomer may be 60° C. or more or 95° C. or more. This promotes rapid resolidification of the polymeric composition after thermoforming and allows the fabric to be cooled after thermoforming. This reduces the time required to cool the fabric, avoiding the need to provide active cooling to the fabric, This can shorten cycle times and reduce energy consumption.

[0030] The knitted component 130 is applied to the first yarn (i.e., the coated yarn). In addition, the yarn (i.e., the first yarn and the second yarn) may be included in the yarn. The thermoformed network of the core yarn is connected by the reflowed and resolidified polymer composition. The presence of reflowed and resolidified polymeric compositions may result in one or more can serve multiple functions, for example, by applying the entire knitted component 130 or a portion thereof (e.g., 130 , controlling the level of stretch only within a certain region of the knitted component 130; forming a skin having high abrasion resistance and / or traction only in a portion of the knit structure; The water resistance of the entire surface of the component 130 or only a portion of the surface may be improved. Included are bonding the entire component 130 or only a portion of it to the substrate.

[0031] The use of the first yarn in knitted component 130 can be used to fabricate the article by eliminating the need for different yarns. The coating on the first yarn, when thermoformed, can also reduce the number of materials that are used. A skin may be formed on the surface of knitted component 130. Alternatively or additionally, a thermoformed The coating of the first yarn when applied bonds the yarns together within the knitted component 130. or as an adhesive for adhering other elements to the surface of knitted component 130. The use of the thermoformed knitted component 130 described herein may provide a durable One or more of the separate elements traditionally added to enhance wear or create traction It may replace the number, reduce waste while improving the recyclability of the article , and simplify the manufacturing process. In addition, creating these properties within the knit structure of the knit component 130 rather than as an additional layer helps the knit component 130 conform to the shape of the wearer's foot and enables more specific receptive feedback, such as when handling a soccer ball. It should be noted that other balls can be used in the footwear described herein without departing from the scope of the technology of this specification . The thermoformed fabric network can form the outer-facing surface of the upper, such as the first surface 105 of the knit component 130 in FIGS. 1A and 1B. Unexpectedly , the thermoformed fabric network created by thermoforming the fabric is excellent in ball contact in that its properties can be equivalent to or better than kangaroo leather in terms of the spin rate imparted to the ball by the upper when kicking the ball. For example, it has been found that using a polymer composition having a durometer hardness (Shore A) of about 65 to about 85 results in an upper with improved ball spin rate. Also, the upper made of the fabric described herein has been found to be equivalent to or better than synthetic leather or a knit upper coated with skin in terms of traction under wet and dry conditions

[0032] . As described herein, the second yarn is knitted integrally with the first yarn to form a thermoformed fabric network in at least a partial region of the knit component 130 .

[0033] ​​​​​​​​​Specifically, knitted component 130 may be formed as an upper The knitted component 13 may have a first surface 105 that forms an outwardly facing surface of the knitted component 13. 0 forms the inward facing surface of upper 102 and is opposite the inward facing surface 102, which is not visible in FIGS. 1A and 1B. The first surface 105 may also include a second surface. The first surface 105 may include a plurality of first regions and a plurality of second regions ( For example, the first region 108 and the second region 106 may be included. To distinguish these regions, the first region 104 is thinner than the second region 106. However, the shading does not indicate the relative position of these regions 104 and 106. It should be understood that coloring is not necessarily limited.

[0034] The first region 108 on the first surface 105 includes a first yarn, and the second region 108 on the first surface 105 includes a first yarn. The second region 106 includes a second yarn. In various embodiments, the second region 106 includes a first yarn. In some embodiments, the first region 108 is a second In another embodiment, the first region 108 is completely or substantially free of yarns as described herein. Without departing from the described technology, it is possible to have a small amount of the first yarn and / or the second yarn. The area 106 may have trace amounts of the second yarn. , as defined herein as less than about 10% by weight of a particular yarn. For example, Less than 0% by weight or less than 10% by weight of the second yarn.

[0035] As described above, the first yarn comprises a first core yarn and a thermoplastic polymer composition. The thermoplastic polymer composition may have a first coating that coats the first core yarn. The second insulating layer may include one or more thermoplastic elastomers at least partially surrounding the second insulating layer. The yarn may include filaments of a thermoplastic material made of polyester. While the second yarn is, in one example, a thermoplastic polymer composition constituting the first coating. Does not include objects.

[0036] As previously explained, the first and second yarns may have different physical properties. For example, a first coating on a first yarn has a first deformation temperature and a second coating on a second yarn has a first deformation temperature. The layer has a second deformation temperature greater than the first deformation temperature. The deformation temperature of 2 is the lower of the melting temperature of the second or the decomposition temperature of the second. The coating of the first yarn or at least the first yarn is such that the structure of the second yarn remains the same. During this time, the melt, flow and / or In various embodiments, the deformation temperature of the coating can be in a melt or molten state. At least 20° C. lower than the second transformation temperature of the first tube. For example, in various embodiments, 1. The melting temperature of the coating of the yarn should be at least 100°C, at least 130°C or at least 170° C., and in each instance, the second deformation temperature is The melting temperature of the coating may be at least 20° C. higher.

[0037] At least in part, the selective use of the first yarn and the second yarn The region 108 has a different coefficient of friction than the second region 106. When the coefficient of friction is mentioned, a common test standard applies to both the first and second regions. For example, determining the static or kinetic coefficient of friction of the first region described herein Therefore, a sample of only the first region can be tested using ASTM D1894. Similarly, samples of only the second region were tested using ASTM D1894 and The static or kinetic coefficient of friction of the second region described in the document can be determined. As explained below, modified versions of ASTM D1894 or other tests are being developed for the first and second areas. As long as a common test standard is applied to both the first and second areas, it is within the scope of the technology of this specification. In other words, the first area is smaller than the second area. If the sample has a high coefficient of friction compared to the sample in the first region, the sample in the second region is exclusively Both samples were subjected to the same test (e.g., same test standard and / or process) and the same conditions ( The only variable measured using the friction coefficient (e.g., wet, dry, temperature) is the coefficient of friction in this example. is the change in the material (e.g., first region and second region) that is to be determined. Therefore, the relative a coefficient of friction (e.g., the first region has a higher coefficient of friction than the second region) A distance between the first region and a second region may be determined.

[0038] In some embodiments, the first region 108 has a higher coefficient of friction than the second region 106. The coefficient of friction can be based on either wet or dry conditions. In this manner, the first region 108 is more porous than the second region in both wet and dry conditions. In one embodiment, the first region tested on a dry sample of football material The dry dynamic friction coefficient of the region 108 is about 0.90 to about 1.50. The wet kinetic friction coefficient of the first region 108 tested with a wet sample of the material ranges from about 0.50 to about In some embodiments, the dry sump of the football material may be 0.80. The difference between the dynamic friction coefficient of the first region 108 in the wet sample of the football material versus the In this manner, the first yarn forming the first region 108 The first region 108 has a football-like shape in both dry and wet conditions. In this way, the first The yarn allows the wearer to have good ball control in various weather conditions. The friction coefficients disclosed herein may also reduce the slippage of the football when wet. All numerical values ​​can be obtained using the Dough-Ball Coefficient of Friction Test described below. .

[0039] Grip (which can be expressed as the coefficient of friction) helps with ball control, but grip Too much pressure reduces the wearer's ability to control the ball. In motion, a soft and quick touch may be desired, and therefore, from the first region 108 Having areas that offset these coefficients of friction provides the best overall grip and ball control. Thus, the second yarn not including the first yarn may be useful for providing an appropriate level of The region 106 has a lower coefficient of friction than the first yarn in wet and dry conditions. For example, the coefficient of friction (wet or dry) of the second region 106 is The coefficient of friction (wet or dry) of the first region 108 is within a range of about 10% to about 75% smaller than that of the or within a range of about 15% to about 60% less than the coefficient of friction (wet or dry) of the first region 1 The coefficient of friction may be within a range of about 20% to about 50% less than that of 08 (wet or dry). .

[0040] The first and second regions 108 and 106 may also have other different physical characteristics. For example, the first coating on the first yarn or the first and second yarns may be The colors may differ based on at least one of the hue, value, and saturation of the colors. Thus, the first region 108 and the second region 106 are divided into groups based on the hue, value, and saturation of their colors. between the first yarn and the second yarn and Other visual differences between the first region 108 and the second region 106 are within the scope of the present invention. However, in some embodiments, the first There is minimal or no visual difference between the first region 108 and the second region 106. However, differences in other physical properties may remain.

[0041] As shown in FIGS. 1A and 1B, the first region 108 and the second region 106 are 102. For example, one of the first regions 108 may have two The second regions 106 may be disposed between each other, in other words, between one of the second regions 106. may be disposed between the two first regions 108. By alternating the first and second regions 106, the upright position is improved for improved ball control. It is possible to provide optimal grip within a portion of the par 102. The size and dimensions of each of the first region 108 and the second region 106 are determined based on the desired grip and and / or the amount of ball control. For example, the size of the first region 108 The size and dimensions of the second region 106 may be similar to or different from the size and dimensions of the second region 106. However, the ratio of the total surface area of ​​the first region 108 to the second region 106 may vary depending on the desired grid size. Depending on the amount of hit and / or ball control, for example, the second area 106 The proportion of the total surface area of ​​the first region 108 is preferably greater than or equal to 100% to provide more grip and / or ball control. If a large number of holes are desired, the total of the first area 108 relative to the second area 106 is The surface area ratio may be smaller if less grip is desired. In the first region 108, the range of about 40% to about 80%, the range of about 50% to about 70% and / or within a range of about 55% to about 65%. The ranges provided herein constitute a percentage of the total surface area within the subarea of ​​face 105. For example, the range 40% to 80% includes 40% and 80%. In addition, the second region 106 is within a range of about 20% to about 60%, within a range of about 30% to about 50%, and and / or between about 55% and about 65% of first surface 105 of knitted component 103. can form a percentage of the total surface area.

[0042] The lateral side of upper 102 depicted in FIG. 1A shows that upper 102 is attached to sole structure 104. When the garment is in a worn configuration with the garment in contact with the ground, it has a generally vertically extending alternating stripe pattern. The first region 108 and the second region 106 are arranged in a circle. Region 108 and second region 106 generally extend from a bottom edge 150 of knitted component 130. At least a portion of bottom edge 150 of knitted component 130 may extend toward seat region 126. A portion of the upper 102 is aligned with a bite line 152 where the upper 102 joins the sole structure 104. By alternately arranging the first region 108 and the second region 106 on the outer side surface, The stripes formed are not only in the forefoot region 116 but also in the lateral midfoot region 114a. Additionally, knitted component 130 may extend into heel region 118. Alternatively, the stripes may extend into the heel region 118. 108 and the second region 106.

[0043] At least some of the stripes may have a zigzag configuration, a wavy line configuration, a parallel line configuration, and / or a nick 3. It is also possible to have any other stripe configuration, such as stripes that follow the curvature of the base component 130. Additionally or alternatively, at least a portion of the stripe may have a varying thickness along its length. For example, the change in width can range from as narrow as 3 millimeters to as narrow as 1 centimeter. The alternating arrangement of the first regions 108 and the second regions 106 may range from 100 mm to 150 mm. Any number of stripes formed in a single stripe may be included in knitted component 130. In some embodiments, first region 108 may include a first region 108 disposed on first surface 105 of knitted component 130. In another embodiment, the first region 108 is formed of nickel. Form between 25 and 35 stripes on the first surface 105 of the component 130. However, the number and configuration of the stripes may vary depending on the grip and / or ball contact desired. the amount of control, then the ratio of the first region 108 to the second region 106, as described above. Depends on the ratio of total surface area.

[0044] On the medial side of the upper 102 depicted in FIG. 1B, a first region 108 and a second region 106 alternately form concentric patterns of shapes or in other words "swirls" or "whirlpools" In this example, the first region 108 and the second region 10 The concentric pattern of 6 includes irregularly shaped circles. The vortex or spiral pattern is a first region. Example of an alternating pattern with a curved boundary between a region 108 and a second region 106 Additionally or alternatively, the concentric shapes may be triangular, circular, oval, parallelogram, pentagonal, or rectangular. Square, hexagonal, star, heart, combinations thereof, or within the scope of the technology described herein. The pattern may be any combination of concentric At least the first region 108 and the second region 108 that are part of the pattern are coaxial and coaxial. The concentric patterns in FIG. 1B are concentric in that they share a common center of gravity. The ball is located in the middle foot region 114b and is slid into the ball such as a soccer ball when kicked. The concentric pattern near the center of the medial midfoot region 114b helps provide a pin. Within the region, the second region 106 is adjacent to the first region 108 in this region of the upper. Thus, more of the first surface 105 may be covered than is otherwise covered.

[0045] In some embodiments, the concentric pattern in the medial midfoot region 114b may include additional A series of alternating first and second regions 108 and additional second regions 106. The stripes may be sandwiched between one or more adjacent concentric patterns. These stripes are shaped according to the curvature or shape of the stripes to form a concentric pattern, as shown in FIG. 1B. The surface may have a curvature or angle corresponding to the angle.

[0046] FIG. 1C illustrates a first region 108 and a second region 106 on the medial surface of the upper 102. 1 illustrates another embodiment of an alternating pattern. In this configuration, first region 108 and The second regions 106 can still form a generally concentric geometric pattern. However, the shape is formed by dashed lines of various lengths and curvatures that accentuate the shape within a concentric pattern. may be made.

[0047] Alternating first regions 108 and second regions 106 on the lateral and medial sides of the upper 102 The use of different types of patterns reflects the different types of movements that may be performed in a particular activity. For example, in soccer, the inside of the foot is used to pass, receive and / or kick the ball. The outside of the foot is often used to kick the ball, while the outside of the foot is used to drag or nudge the ball. For this reason, the first area 108 and the second area 10 By varying the ratio or pattern of the six, different grip patterns can be provided for specific activities. For example, the concentric pattern of the medial midfoot region 114b may be 106, which provides a more omnidirectional distribution of the coefficient of friction between the first region 108 and the second region 106. Allows for better ball control for receiving, passing and / or kicking actions As mentioned above, the concentric pattern may also be used to improve the ball's grip when the wearer kicks the ball. In contrast, the outer flank strikes the ball with more or less spin. The rib pattern extends more longitudinally (i.e., from the forefoot region 116 to the heel region 118). 107), and the friction coefficients of the first region 108 and the second region 107 are distributed in the direction of the driving force. This may allow for better control of the ball while locking or nudging.

[0048] The embodiments described herein include concentric patterns and stripes disposed on a footwear upper. A pattern is characterized by different tasks that can be performed in a particular action. may additionally or alternatively be placed on the sole or bottom of the footwear to reflect the movement of the Specifically, in the front or toe area of ​​the outsole 109, The coefficient of friction of the first region and the second region is different from that of the rear or heel region of the outsole 109. The pattern may be customized to include dispersion.

[0049] As discussed above, some embodiments of knitted component 130 may be constructed using two knitting beds. The first yarn and the second yarn are formed on the first yarn. and the second yarn may alternately form a first surface 105 of the knitted component 105. , in courses and / or along ridges, knit loops on the front bed and back bed For example, the first yarn may be used together with the front bed to form the upper loop. A loop may be formed on the needle of the second yarn to form the first region 108 and The second region 10 forms a lift or loop on the needle of the back bed. 6, the first yarn floats or forms a loop on the needles of the back bed Meanwhile, the second yarn is formed as it forms loops on the needles of the front bed. obtain.

[0050] In some embodiments, knitted component 130 is made of elastane or elastic polyurethane. In an exemplary embodiment, the third yarn comprises a material that is a first surface. 105 is knitted on a second surface of knitted component 130 opposite knitted component 105. The yarns are arranged in a first region 108 on the first surface 105 and in a region opposite the second region 106. In some embodiments, the third yarn may be knitted on the second surface in a region. The third yarn is present only on the second surface and not on the first surface 105. The third yarn is knitted on only one needle bed, i.e. the back needle bed. Elastane or elastic polyester on a second surface (e.g., an inward-facing surface) of knitted component 130. The inclusion of a urethane material provides a degree of elasticity to knitted component 130, This occurs when the knitted component 130 on the upper 102 is in contact with an object, such as a ball. , enhancing proprioceptive feedback to the wearer.

[0051] As described above, the first yarn is melted or deformed by thermoforming and then solidified. The core yarn in the first yarn and one or more other yarns, such as the second yarn The coating may form a thermoformable network with the yarn and, in some embodiments, with a portion of the third yarn. In this manner, the thermoforming process reduces the knit structure of knitted component 130. For example, after knitting, knitted component 130 may be , may include interconnected courses of loops of the first yarn and the second yarn; And after thermoforming, knitted component 130 is resistant to deformation or melting of the coating of the first yarn. At least in part due to the loops of the first and second yarns in the thermoformed portion. At the same time, the first yarn may not include any interconnected courses of the core. The yarn still forms an interconnected loop with the second yarn, and the remaining loop may still be connected through the melted and resolidified garment material.

[0052] FIG. 2A illustrates an exemplary knitted component, which may be knitted component 130 of FIGS. 1A-C, prior to a thermoforming process. 2 shows a schematic representation of a portion 200 of a hub component. The portion 200 is a first embodiment of the hub component described herein. The first yarn 210 is a coated yarn and the second yarn 212 is a coated yarn. The portion 200 includes interconnected courses of a second yarn 208 that is a second yarn. A first course 202 and a second course 204 having a second yarn 208, and In such an embodiment, the first course 206 of the first yarn 210 The third course 206 of loops is connected to the first course 202 having the second yarn 208 and The second course 204 may be interconnected (eg, interfering).

[0053] FIG. 2B depicts part 200 after it has been subjected to a thermoforming process. As can be seen by comparing the B, the thermoplastic polymer composition as described herein The first yarn 210 is made of a solid yarn structure and is thermally transformed into a molten yarn component 212. The core yarn 214 of the first yarn 210 is formed in its interlooped configuration. In one embodiment, the heating step of the thermoforming process comprises at least partially melting and flowing the coating in the first yarn 210, and then , which solidifies into molten yarn component 212 upon completion of the thermoforming process. The yarn component 212 is a coating that surrounds the core yarn 214 of the first yarn 210. After the coating has melted, flowed, and resolidified. The molten yarn component 212 contacts the core yarn 214 of the first yarn 210 and at least It partially encircles both of these and interloops with a third course 206 which forms a network. or at least a portion of adjacent first course 202 and second course 204, It is depicted as contacting and at least partially surrounding a portion of the second yarn 208 . However, the fused yarn component 212 may deviate from the techniques described herein. 2B. It can be thermoformed to a wide range.

[0054] The part having the fused yarn component 212 created from thermoforming is made of the thermoformed fused yarn. Increased abrasion resistance and increased water resistance properties compared to areas without the spin component 212. Moreover, these properties may be achieved without the need for additional layers or films. Since the knitted component portion 200 is provided through the knit structure rather than being cut with a thin layer of plastic, the knitted component portion 200 is relatively thin. and can remain flexible, so that the fused yarn component 212 is less likely to wear or break prematurely. in highly flexible areas of the upper, such as the area between the throat and forefoot area, without It can be used.

[0055] 2A and 2B are merely examples of knitting and thermoforming as described herein. Please note that the yarns may be mainly made of the first yarn 210 or mainly made of the second yarn 208. Any number of adjacent rows and / or any number of adjacent loops may be used as the body. The knit pattern may be any of the knit patterns described herein without departing from the scope of the technology described herein. A first region (such as first region 108 in FIGS. 1A-1C ) or a second region (such as first region 108 in FIGS. 1A-1C ) on a surface of the knitted component. 1A-1C)。 For example, for ease of illustration, portion 200 is shown with only a single knit layer. However, some embodiments of the present disclosure use needles on two needle beds. It is contemplated that the knitted component may include a knitted component having a double knit structure formed using For example, first yarn 210 may form a first surface of the knitted component as shown in FIG. The third course 206 may be knitted on the front needle bed to form loops. , and in another course, such as a course knitted simultaneously with the first course 202, The knitted component includes a back knit member 210 for forming at least a portion of the second surface of the knitted component. Similarly, the second yarn 208 may be knitted on a yarn bed in the first course of FIG. 202 and the second course 204 are knitted on the front bed needles to form the loops. This may form a first surface of the knitted component, and may be further processed into another course, e.g. For example, in a course knitted simultaneously with the third course 206, the second yarn 208 is in a knit structure. and knitting the back needle bed to form at least a portion of the second surface of the component. In some embodiments, the first yarn 210 and / or the second yarn 208 may be The needle beds may be moved back and forth between the front and back needle beds in one course. In some embodiments where the 0 is part of a double knit structure, the course for the second surface is The forming loop is formed from a third yarn having an elastane or elastic polyurethane material. Additionally, in some embodiments having a double knit construction, the fused yarn components may be The fabric 212 may extend between the knit layers, but does not extend completely through the back layer to form the second surface. In an alternative configuration, the molten yarn component 21 may not be fully extended. 2 may still extend completely through both knit layers of a double knit structure. do.

A knitted component 130 as described herein having a first region 108 and a second region 106. The first region 108 may be made of a first yarn and the second region 106 may be made of a second yarn. The thermoforming of such knitted components, as described herein, may include the steps of: It can be used to reflow and resolidify the coating on the first yarn, The covering material occupies at least a portion of the spaces between the yarns of the thermoformed yarn network. As will be further described below, during thermoforming, knitted component 130 may be molded into a flat sheet. Or pressure may be applied while in contact with the molding surface, such as in a conventional two-piece mold. In some embodiments, the molding surface is on first surface 105 of knitted component 130. It may include recessed and / or raised elements to form a texture having raised elements. The raised elements molded into the knit structure of knitted component 130 advantageously enhance the knit Between the first surface of the component 130 (which may be the outer surface of the upper) and the football The amount of grip may be used to adjust the grip effect of the knitted component. In particular, the raised elements provide a higher coefficient of friction (i.e., Thus, the raised elements provide a cushioning effect on the first region 10. 8 may be disposed on a portion of knitted component 130 forming a larger portion of the surface area. Additionally, in some embodiments, the raised elements are located on the lateral side of the upper and the medial side The upper is not placed on the face, or the medial side of the upper does not have as many raised elements as the lateral side. is possible.

[0057] Raised elements 160 come in a variety of shapes, sizes and configurations within knitted component 130. In FIG. 3A, the raised elements 160 are closely spaced and run parallel to one another. Within this exemplary pattern, the ridges form elongated ridges or grooves that extend along the length of the Additionally, the ridges in FIG. 3A may be present in both the first region 108 and the second region 106. Further, the ridge extends longitudinally between the first region 108 and the second region 106. The ridges may form recesses between them similar to grooves. The ridges 130 wick moisture and other small debris away from first surface 105 of knitted component 130 . This allows for a better contact surface with the ball, as well as , better grip and / or ball control in wet and / or dirty conditions Additionally, the elongated parallel grooves on the lateral side of the upper improve drag, nudging and other Such techniques may be particularly advantageous. In some embodiments, the grooves or recesses between the ridges include: The width and / or spacing are between or approximately 1 millimeter to 1 centimeter apart. However, as noted above, the pattern, width and / or spacing of the ridges may be varied as desired. The clubhead may be fine-tuned to adjust grip and / or ball control.

[0058] In FIG. 3B , raised elements 160 extend from first surface 105 of knitted component 130. The protrusions in FIG. 3B are in the form of tetrahedral or pyramidal protrusions protruding from the first region 1. In other embodiments, the protrusions may be located in both the first region 108 and the second region 106. 8. Furthermore, the projections are generally arranged in a straight line, as shown in FIG. 3B. The electrodes may be spaced apart or may be arranged in a more dense or random pattern.

[0059] In FIG. 3C, the raised elements 160 form closely spaced, elongated ridges. The ridges may be spaced approximately equidistant from one another. Within this exemplary pattern, the ridges may have different lengths. Often, slightly curved or curvilinear rows and / or columns of elongated ridges or grooves. Similar to the raised element 160 in FIG. 3A, the raised element 160 in FIG. The ridges extend across both the first region 108 and the second region 106. , may extend substantially perpendicular to the longitudinal direction of the first region 108 and the second region 106. The ridges may also form recesses similar to grooves between the ridges, so the ridges may also form knit construction elements. 130. The first surface 105 of the substrate 130 is then operative to wick away moisture and other small debris. This allows for a better contact surface with the ball. The grooves or recesses between the ridges have a width and / or spacing between each other of between 1 millimeter and 1 centimeter. The raised elements 160 depicted in FIGS. 3A-3C are merely exemplary. The first surface 105 of the knitted component 130 is patterned according to the techniques described herein. The texture or pattern may be flat, shiny, bumpy or matte without departing from the scope of the present invention. Note that the material may be thermoformed to have a void.

[0060] 4 and 5A-5B show first and second casings different from those shown in FIGS. 1A-1C. FIG. 4 depicts an embodiment of a knitted component for footwear having an alternating pattern of regions. 1 depicts footwear 400 having a sole structure 404 and an upper 402. The embodiment has generally the same configuration as described with respect to sole structure 104 of Figures 1A-1B. Additionally, the embodiment of upper 402 may be similar to that described with respect to upper 102 of FIGS. 1A-1B. The upper has generally the same construction. Thus, the upper is at least partially constructed of knitted component 43. 1. An embodiment of knitted component 430 may be formed from a material other than cellulose ester resin 410, and may be similar to that shown in FIG. It may have substantially the same configuration as described with respect to knitted component 130 in A-1B.

[0061] Knitted component 430 includes at least a first yarn having different material compositions and different properties. The knitted component 430 is formed from a first yarn and a second yarn. Knitted component 4 may be formed using the materials and techniques described above in connection with element 130. The first surface 405 of the upper 30 forms the outwardly facing surface of the upper and is formed from the first yarn. A first plurality of regions (first region 408) formed of the second yarn and a second plurality of regions (second region 409) formed of the second yarn. The second region 406 may have a first region 408 .

[0062] Similar to the first region 108 and the second region 106 in FIGS. 1A-1B, the first region 408 and The first and second regions 408 and 406 may have different coefficients of friction. The wet and dry coefficients of friction may be greater than those of the second region 406. The first region 408 and the second region 406 are disposed on at least the medial side of the upper 402. Specifically, the first region 408 and the second region 406 may be arranged alternately. Alternating arrangements to form concentric patterns such as regular shaped circles and / or ellipses A central region of the concentric pattern is disposed in the medial midfoot region 414. Unlike knitted component 130 of FIGS. 1A and 1B, second region 406 may include a It does not have to have a width substantially greater than the concentric first region 408 adjacent the central region. Rather, the concentric circles or ellipses that form the first region 408 in the central region are The second region 406 has a surface area similar to that of the concentric circles or ellipses forming the second region 406 in the domain. As a result, the central region of the concentric pattern of the medial midfoot region 414 may be The medial midfoot region 114a of FIG. 1B has a larger grip than the central region of the concentric pattern. A pool may be provided.

[0063] The first region 408 and the second region 406 are also patterned in the same manner as described with respect to FIG. 1A.
