Description

[0001] This application is a divisional application of the application filed on July 12, 2019, with application number 201980068401.1 and invention title "Knitted Part with Protruding Structure and Manufacturing Method". Background Technology

[0002] Various articles are formed from textiles. As examples, clothing articles (such as shirts, trousers, socks, footwear, jackets and other outerwear, briefs and other underwear, hats and other headwear), packing materials (such as backpacks and bags), and upholstery for furniture (such as chairs, sofas, and car seats) are typically at least partially formed from textiles. These textiles are often formed by weaving or interlacing (e.g., knitting) one or more yarns, usually through mechanical processes involving looms or knitting machines. A specific type of object that can be formed from textiles is the upper of footwear.

[0003] Conventional footwear typically comprises two main components: the upper and the sole structure. The upper is attached to the sole structure and forms a cavity within the footwear to comfortably and securely accommodate the foot. The sole structure is attached to the underside of the upper to position it between the upper and the ground. For example, in athletic footwear, the sole structure may include a midsole and an outsole. The midsole may be formed of a polymer foam material that dampens ground reaction forces during walking, running, and other walking activities to reduce stress on the foot and leg. The outsole may be attached to the underside of the midsole and forms the ground contact portion of the sole structure, which is formed of a durable and abrasion-resistant material.

[0004] The upper of footwear typically extends along the medial and lateral sides of the foot, and around the heel area, across the instep and toe regions. The entrance to the internal cavity of the upper is usually provided by an ankle opening in the heel area. A lacing system is often incorporated into the upper to adjust its fit, facilitating entry and exit of the foot through the internal cavity. The upper may include a tongue extending below the lacing system to enhance adjustability, and may incorporate a heel stabilizer to restrict heel movement. Summary of the Invention

[0047] The various aspects are described below with reference to the accompanying drawings, in which the same elements are generally denoted by the same reference numerals. A better understanding of the relationships and functions of the various elements in each aspect can be achieved by referring to the following detailed description. However, the aspects are not limited to those illustrated in the drawings or explicitly described below. It should also be understood that the drawings are not necessarily drawn to scale, and in some cases, details unnecessary for understanding the aspects disclosed herein (e.g., conventional manufacturing and assembly) may be omitted.

[0048] Certain aspects of this disclosure relate to articles formed at least in part from textiles. An example of an article is clothing articles (e.g., shirts, trousers, socks, footwear, jackets and other outerwear, briefs and other underwear, hats and other headwear, etc.). The article can be an upper configured for use in footwear articles. Uppers can be used in conjunction with any type of footwear. Illustrative, non-limiting examples of footwear articles include basketball shoes, cycling shoes, cross-training shoes, global football (English football) shoes, American football shoes, bowling shoes, golf shoes, hiking shoes, ski or snowboard boots, tennis shoes, running shoes, and walking shoes. Uppers can also be incorporated into non-athletic footwear (e.g., dress shoes, slippers, and sandals).

[0049] One aspect of the invention includes a knitted component having a first knitted layer and a second knitted layer, the first and second knitted layers extending at least partially together to form a pocket. A third yarn is positioned at least partially within the pocket and between the first and second knitted layers. The third yarn is secured to the first knitted layer at a first position within the pocket and to the second knitted layer at a second position within the pocket.

[0050] One or more aspects of the present invention provide the advantage of forming a knitted component having at least one raised structure formed by a first knitted layer, a second knitted layer, and a third yarn at least partially positioned between the first and second knitted layers. The third yarn of the knitted component is visible through the second knitted layer at at least one location of the at least one raised structure.

[0051] One or more aspects of the present invention provide the advantage of forming a knitted component for an upper of a footwear article having a plurality of raised structures, wherein the color of the raised structures is visible from the outer surface of the upper and can vary based on the structure, configuration and position of at least one yarn within the raised structure.

[0052] Reference Figures 1 to 2 Footwear article 100 may include an upper 102 attached to a sole structure 104. The upper 102 may include an outer side 106 and an inner side 108. The area of ​​the sole structure 104 where the upper 102 is attached to the shoe may be referred to as a biteline 110. The upper 102 may be attached to the sole structure 104 in a secure manner using any suitable technique, such as by using adhesives, by stitching, etc. It is conceivable that the upper 102 may extend partially or completely around the wearer's foot and / or may be integral with the sole, and may or may not use an insole. In some embodiments, the sole structure 104 may include a midsole (not shown) and an outsole.

[0053] Footwear article 100 may additionally include a throat region 112 and an ankle opening 114, which may be surrounded by a collar 116 and open to a cavity 118. The cavity 118 of footwear article 100 may be configured to receive a person's foot. The throat region 112 may typically be located in a midfoot region 120 of the upper 102. The midfoot region 120 is typically the region of the upper 102 located between a heel region 122 and a toe region 124. In some embodiments, a tongue may be located in the throat region 112, but the tongue is an optional component. The tongue can be any type of tongue, such as a gusseted tongue or a burrito tongue. If the tongue is not included, the outer and inner sides of the throat region 112 may be combined. As shown, in some embodiments, footwear article 100 may include optional fastening elements, such as laces (which may be associated with lace holes 126). Any suitable type of fastening element may be used.

[0054] The upper 102 may further include one or more structures, including but not limited to at least one pod 160 having at least one protruding structure 128. (See reference...) Figures 3 to 5The pod 160 includes at least one side demarcated by an edge region, such as a second region 130. As described in more detail below, a stimulus (e.g., heat or steam) may be applied to the upper 102 to form at least one raised structure 128 (and / or enhance its loft). The raised structure 128 can be of various shapes and sizes, and in one instance, can be a generally spherical structure. The second region 130 may surround the periphery of the raised structure 128 or at least one side to form the pod 160. Figure 4 As shown, a cross-sectional view of the knitted part 132 is illustrated. The height 130a, or in other words, the thickness, and the width 130b of the second region 130 are much smaller than the height 128a, or the thickness, and the width 128b of the protruding structure 128.

[0055] The pod 160 is formed of two (or more) knitted layers that at least partially overlap and extend together, forming a pocket 159 within the pod 160. When exposed to a stimulus (e.g., heat or steam), the second knitted layer extends away from the first knitted layer to form a raised structure 128 (described in more detail below). A second region 130 demarcating the pod 160 may also be formed of two (or more) knitted layers (described in more detail below). Elements may be placed within the pocket (e.g., a floating portion of the yarn). The raised structure 128 may be arranged at any suitable location on the footwear article, such as in the heel area 122, midfoot area 120, toe area 124, medial side 108, lateral side 106, and / or other locations or combinations thereof. The raised structure 128 may facilitate providing the footwear article 100 with suitable cushioning, stiffness (e.g., without sacrificing flexibility in certain directions), durability, desired aesthetic characteristics, or other properties. Any suitable number of protrusions 128 may be included. In some embodiments, multiple protrusions 128 may be included. In a non-limiting example, such as Figure 1 and Figure 2 As shown, multiple protrusion structures 128 may exist. An example of a protrusion structure is described in U.S. Provisional Patent Application No. 62 / 702,248, filed July 23, 2018, which is incorporated herein by reference in its entirety.

[0056] At least a portion, and in some embodiments substantially the entire upper 102, of the shoe upper 102 may be formed of a knitted component 132, which may be formed, for example, on a flat knitting machine by a weft knitting process. The knitted component 132 may additionally or alternatively form another element of the footwear article 100, such as the foot portion. Figures 3 to 5As shown, the knitted component 132 may have a first side 134 forming the inner surface of the upper 102 (e.g., facing the cavity 118 of the footwear article 100) and a second side 136 forming the outer surface of the upper 102 (e.g., generally facing opposite to the first side 134). The first side 134 and the second side 136 of the knitted component 132 may exhibit different properties (e.g., the first side 134 may provide abrasion resistance and comfort, while the second side 136 may be relatively rigid and provide desired aesthetic characteristics, water resistance, and other advantageous properties mentioned herein). The knitted component 132 may be formed as a single, integral element during a knitting process, such as weft knitting (e.g., using a flat knitting machine or a circular knitting machine), warp knitting, or any other suitable knitting process. That is, the knitting process on the knitting machine can substantially form the knitted structure of the knitted component 132 without requiring significant post-knitting processes or steps. Alternatively, two or more portions of the knitted component 132 may be individually formed as different, integral single elements, and then the individual elements are attached.

[0057] Forming the upper 102 with the knitted component 132 can provide the upper 102 with advantageous properties, including but not limited to a certain degree of elasticity (e.g., expressed in Young's modulus), breathability, flexibility, strength, moisture absorption, weight, abrasion resistance, and / or combinations thereof. These properties can be achieved by selecting a specific single or multi-layer knitted structure (e.g., rib knitted structure, single-sided plain knitted structure, or double-sided plain knitted structure), by changing the size and tension of the knitted structure, by using one or more yarns formed from a specific material (e.g., polyester, a relatively inelastic material, or a relatively elastic material such as spandex), by selecting yarns of a specific size (e.g., denier), and / or combinations thereof. The knitted component 132 can also provide desired aesthetic properties by including yarns with different colors, reflectivity, texture, or other visual characteristics arranged in a specific pattern.

[0058] The yarn itself and / or the knitted structure formed by one or more yarns of the knitted component 132 can vary at different locations, such that the knitted component 132 has two or more portions with different properties (e.g., the portion forming the throat region 112 of the upper 102 may be relatively elastic, while another portion may be relatively inelastic). In some embodiments, the knitted component 132 may comprise one or more materials having properties that change in response to stimuli (e.g., the application of steam and / or other forms of heat, moisture, electric current, magnetic field, or light).

[0059] For example, the knitted component 132 may comprise yarns formed of a thermoplastic polymer material (e.g., polyurethane, polyamide, polyolefin, and nylon) that, when subjected to certain temperatures equal to or above its melting point, transforms from a solid state to a softened or liquid state, and then transforms back to a solid state upon cooling. The thermoplastic polymer material provides the ability to heat and then cool a portion of the knitted component 132, thereby forming a region of molten or bonded or continuous material that exhibits certain advantageous properties, including, for example, relatively high stiffness, strength, and water resistance.

[0060] The knitted component 132 may include a seamless portion extending from the toe region 124 through the midfoot region 120 and reaching the heel region 122 on at least one of the outer side 106 and the inner side 108 of the upper 102. In some embodiments, the knitted component 132 may include a first edge (not shown) and a second edge (not shown) that may be the ends of the knitted component 132 after the knitting process when the knitted component 132 is removed from the knitting machine. After the knitting process, the knitted component 132 may be folded or otherwise manipulated such that the first edge and the second edge are held together at a seam (not shown) during the formation of the upper 102. The seam may be located on the outer side 106 of the upper 102, on the inner side 108 of the upper 102, and / or at another location (e.g., at the rear of the heel region 122 of the upper 102). Forming the upper 102 to have a shape suitable for inclusion in the footwear article 100 may also include lasting the upper 102. Examples of the last-forming process are described in U.S. Patent Application No. 12 / 848,352, filed August 2, 2010, which is published as U.S. Patent No. 8,595,878, the entire contents of which are incorporated herein by reference.

[0061] When forming the knitted part 132, the knitted part 132 may be oriented relative to the needle bed of the knitting machine such that the toe region 124 is knitted first, followed by the midfoot region 120, and then the heel region 122 (or vice versa, wherein the heel region 122 is knitted first and the toe region 124 is knitted last). In this embodiment, the courses of the knitted part 132 are knitted from the inside 108 to the outside 106 (or vice versa, from the outside 106 to the inside 108). In another embodiment, the knitted part 132 may be oriented relative to the needle bed of the knitting machine such that the first course of the knitted part 132 is knitted to extend from the heel region 122 through the midfoot region 120 and to the toe region 124 (or vice versa, wherein the first course of the knitted part 132 is knitted to extend from the toe region 124 through the midfoot region 120 and to the heel region 122). In this second embodiment, the loop rows of the knitting component 132 are knitted from the heel region 122 to the toe region 124 (and vice versa, from the toe region 124 to the heel region 122). In both embodiments, additional loop rows are formed parallel to the first loop rows of the knitting component 132.

[0062] The loop rows of the knitted part 132 can be formed by a single pass on the knitting machine, or in other words, by knitting across the needle bed of the knitting machine from left to right or from right to left. In another embodiment, the loop rows of the knitted part 132 can be formed by two passes on the knitting machine, or in other words, by knitting across the needle bed of the knitting machine from left to right and then from right to left (or vice versa). Those skilled in the art will understand how the knitted part 132 is manufactured, whether a single pass is referred to as a loop row or two passes are referred to as a loop row. Each loop row may include one or more yarns dispensed from the yarn feeder during each pass.

[0063] In some embodiments, each loop row may include a continuous strand of yarn extending between the outer side 106 and the inner side 108 of the upper 102 or between the heel region 122 and the toe region 124. Additionally or alternatively, one or more strands of yarn forming at least a portion of each loop row may extend less than the full length of the first loop row. For example, it is conceivable that a strand of yarn may extend from one side of the upper (e.g., the outer side 106 or the inner side 108) to the other side of the upper, but may terminate within the loop row before reaching the other side. In a non-limiting example, when forming a loop row, a strand of yarn may extend from the outer side 106 toward the inner side 108, but terminate before reaching the inner side 108. The loop row may continue toward the inner side 108 without interruption, but an additional or alternative, different second strand of yarn may pick up at the termination of the first yarn. Alternatively, the first and second strands may be combined such that the loop row is knitted with the combination of the first and second strands.

[0064] like Figures 7A to 7B As shown (and described in further detail below), the loop rows of the knitted component 132 may at least partially form portions of the pod 160, the raised structure 128, and / or the second region 130. Figures 3 to 4 A close-up cross-sectional view of a portion of the knitted part 132 is shown. Although Figure 3 A partial cross-sectional view of the knitted part 132 before it is subjected to stimulation (e.g., including but not limited to steam or heat) is shown. Figure 4 A partial cross-sectional view of the knitted part 132 after being subjected to post-manufacturing processes or stimulating treatments (including but not limited to steam 166) is shown.

[0065] like Figure 3 and Figure 4 As shown, at least a portion of the upper 102 (e.g., pod 160) may have a first layer 154, a second layer 156, and an optional third layer 158 (also referred to as an intermediate layer). The pod 160 is formed by the first layer 154 and the second layer 156, which extend together and / or overlap each other, forming a pocket 159 therebetween. The pod 160 is demarcated on at least one side by a second region 130. The third layer 158 is positioned within the pocket 159 of the pod 160 between the first layer 154 and the second layer 156, as... Figures 3 to 5 As shown. Within the pod 160, a third layer 158 is fixed or otherwise connected to a portion of the first layer 154 and a portion of the second layer 156 (described in more detail below). The second layer 156 of the pod 160 and, in some embodiments, the third layer 158, form protrusions 128 when stimulated (e.g., including but not limited to heat, steam, or temperature), such as Figure 4 and Figure 5 As shown. Figure 3 As shown, before stimulation is applied, the second layer 156 of the pod 160 may partially bulge. After stimulation is applied to form the bulging structure 128, the second layer 156 of the pod 160 will bulge further (e.g., move away from the first layer 154).

[0066] In other parts of the upper 102, such as the second region 130, a multi-layered knitted structure is not required (but is included in the depicted embodiment). In the second region 130, as... Figures 3 to 5 As shown, the first layer 154 and the second layer 156 extend together at least partially and / or overlap, and are connected to each other in at least one portion, and the third layer 158 floats or is embedded between the first layer 154 and the second layer 156 (described in more detail below). As described above, as Figures 4 to 5As shown, the height or thickness 130a and width 130b of the second region 130 are smaller than the height or thickness 128a and width 128b of the protrusion structure 128. Therefore, when the knitted part 132 is stimulated, due to the size of the second region 130, the arrangement of the first layer 154, the second layer 156 and the third layer 158 within the second region 130, the connection of the first layer 154 and the second layer 156 within the second region 130, and the fact that the third layer 158 is not connected to the first layer 154 and the second layer 156 within the second region 130, the second region 130 does not form the protrusion structure 128.

[0067] At least in pod 160, both the first layer 154 and the second layer 156 can be formed by the annular structure of the knitted part 132, such that they are formed primarily on a knitting machine. The third layer 158 is also formed primarily on a knitting machine together with the first layer 154 and the second layer 156. However, as described in more detail below, the third layer 158 may generally lack the annular knitted structure (i.e., interlocking loops) within pod 160, and therefore may at least partially float between the first layer 154 and the second layer 156. In some embodiments, the third layer 158 may be secured to at least one of the first layer 154 and the second layer 156 via a tucked structure and / or loops. For example, in Figures 3 to 5 In each of the raised structures 128, the third layer 158 is secured to a portion of the first layer 154 at a first position 162a within the pocket 159, and to a portion of the second layer 156 at a second position 164a within the pocket 159. In each of the second regions 130, the third layer 158 may be formed as an embedded strand of yarn located between opposing surfaces of the knitted component 132, as shown; however, alternatively, the third layer 158 may be incorporated into one or more knitted loops of the second region 130.

[0068] When the knitted component 132 is included in the upper 102, the second layer 156 may form a portion of the outer surface of the upper 102, and the first layer 154 may form a portion of the inner surface of the upper 102. In one embodiment, such as Figures 3 to 5 As shown, the second layer 156 forms a portion of the outer surface of the upper 102 at each of the protrusions 128 and a portion of the inner surface of the upper 120 at each of the second regions 130. The first layer 154 forms a portion of the inner surface of the upper 102 at each of the protrusions 128 and a portion of the outer surface of the upper 120 at each of the second regions 130.

[0069] Each protruding structure 128 may be separated by a second region 130 on at least one side. For example... Figures 1 to 2As shown, the protrusions 128 may be parallel or substantially parallel to each other along a "first direction" A (where direction A is a "lateral" direction, or a direction substantially parallel to the longitudinal direction of the loop rows extending through the knitted component 132). In the depicted embodiment, direction A is illustrated as an inside-to-outside direction, substantially along... Figure 2 The y-axis is shown, but the rows of loops can alternatively extend through the knitted part 132 in different directions. The raised structures 128 can also (or alternatively) be parallel or substantially parallel to each other along a "second direction" B, which can be a longitudinal direction perpendicular to direction A (illustrated as heel-to-toe, substantially along...). Figure 2 (The x-axis is shown). In alternative embodiments, such as... Figures 5 to 7B As shown, the protruding structures 128 can be offset from each other along either a first direction A or a second direction B, and are substantially parallel to each other along the other of the first direction A and the second direction B. Figure 5 As shown in the cross-sectional side view, the protrusions 128 are parallel or substantially parallel to each other along a first direction A and offset from each other along a second direction B. In an alternative embodiment, the protrusions 128 may be parallel or substantially parallel to each other along the second direction B and offset from each other along the first direction A. When the knitted part 132 is formed on a knitting machine, the first direction A may be substantially parallel to the needle bed. In an alternative embodiment, when the knitted part 132 is formed on a knitting machine, the second direction B may be substantially parallel to the needle bed.

[0070] Various processes are envisioned for generating the raised structure 128, and these processes can occur during or after the knitting process used to form the knitted part 132. For example, the upper 102 can be knitted on a knitting machine having a front bed and a back bed. In one example, yarn knitted on the back bed can ultimately form a first layer 154 of the knitted part 132, and yarn knitted on the front bed can ultimately form a second layer 156 of the knitted part 132. Yarn can float through the needles of the knitted part 132 to form a third layer 158, and be gathered to one of the needles on the back bed to connect the third layer 158 to the first layer 154, and gathered to one of the needles on the front bed to connect the third layer 158 to the second layer 156.

[0071] One or more yarns may be used when knitting the knitted part 132. In a non-limiting example, the first yarn may be used to form a first knitted layer 154 (at least in the pod 160) of the knitted part 132, which forms at least a portion of a first side 134 of the knitted part 132, which forms the inner surface of the upper 102. The first yarn may include, for example, a relatively elastic yarn. One or more warp ends of the first yarn may be used, such as one warp or two or more warp ends. Preferably, in this example, one warp end of the first yarn may be used. In a non-limiting example, the first yarn may be an “EO4” type yarn supplied by Unifi, Inc., located in Greensboro, North Carolina, which preferably has relatively high elasticity compared to other yarns that may be used to form the knitted part 132. The first yarn may include a polyester-wrapped spandex core (i.e., Lycra). It can have a denier range of about 800D to about 1050D, a tensile strength greater than 0.75 kgf, and an elongation of 180% to 250%. Denier is a unit of measurement for fiber linear density, measured in grams per 9000 meters. In some embodiments, such as when it is desired that the first yarn be dimensionally reduced in the manufacturing process, the shrinkage rate of the first yarn (also referred to as the first shrinkage rate) may be higher than that of other yarns used to form the knitted part 132 when heated (or otherwise stimulated). In other words, for example, when heated (e.g., via steam), the first yarn may shrink more and / or have a higher shrinkage rate than other yarns used to form the knitted part 132. In one example, the shrinkage rate of EO4 from Yihua Yuhui Company was tested using a standard jacquard square procedure, and the results are provided in the table below.

[0072]

[0073] A second yarn may be used to form a second knitted layer 156 of the knitted component 132, the second knitted layer 156 forming at least a portion of a second side 136 of the knitted component 132, the at least portion of the second side 136 forming the outer surface of the upper 102. The second yarn may be the same as or different from the first yarn. In one example, the second yarn used to form at least a portion of the second side 136 of the knitted component 132 (which forms at least a portion of the outer surface of the upper 102 within the pod 160) is a yarn with different properties relative to the first yarn. The second yarn may comprise a combination of materials or strands. One or more warp yarns of the second yarn may be used, such as one warp yarn, two warp yarns, or more than two warp yarns. For example, the second yarn may comprise a combination of a warp yarn of a "monofilament" type yarn and a warp yarn of a yarn formed from a thermoplastic polymer material (sometimes called a fusible yarn).

[0074] The monofilament yarn of the second yarn can be supplied by Formosa Ting Sho in Taiwan, and can be referred to as 0.125mm monofilament nylon. This monofilament yarn can have relatively low elasticity compared to the first yarn used to form the knitted part 132. When stimulated (e.g., by temperature, heat, or steam), the monofilament yarn of the second yarn can expand or have minimal shrinkage. The monofilament yarn can have a denier range of about 125D to about 150D, a tensile strength of about 0.8 kgf to 1.2 kgf, and an elongation of 16% to 25%. As mentioned above, denier is a unit of measurement for fiber linear density, measured in grams per 9000 meters.

[0075] The fusible yarn of the second yarn may be manufactured by EMS-Griltech of Dorma, Switzerland, and may also have relatively low elasticity compared to other yarns that can be used to form the knitted part 132. The fusible yarn is a low-melting-point yarn that provides stiffness, structure, and strength to the knitted part 132 upon exposure to a stimulus (e.g., temperature, heat, or steam). The fusible yarn has a melting temperature of 65 degrees Celsius, a denier (explained above) range of about 140D to about 170D, a tensile strength greater than 0.375 kgf, and an elongation of 53% to 74%. Fusible yarns of different colors may be used. In one example, the fusible yarn may have a translucent color, such that when a stimulus (e.g., temperature, heat, or steam) is applied to the second yarn, the fusible yarn melts, making the second yarn more translucent, allowing the color of the yarn of the third layer 158 to be visible from the outer surface of the upper 102. When stimulated (e.g., by temperature, heat, or steam), the fusible yarn of the second yarn can expand or have low to minimal shrinkage.

[0076] The shrinkage rate of the second yarn when exposed to steam (or another stimulus) relative to the first shrinkage rate of the first yarn forming the knitted part 132 is also referred to as the second shrinkage rate. In other words, when subjected to a similar amount of heat (e.g., via temperature, heat, or steam), the second yarn may shrink much less (if any), have a lower shrinkage rate than the first shrinkage rate of the first yarn used to form the knitted part 132, and / or expand. For example, a combination of materials, such as monofilament yarns and fusible yarns, forming the second yarn together, can be achieved by twisting, winding, braiding, and / or wrapping around another yarn, and / or the yarns can be in a core / sheath configuration, and / or the yarns can be secured at multiple points along their length. In one example, the shrinkage rates of a 0.125 mm monofilament yarn (supplied by Hi-Tech Corporation of Korea) and a fusible yarn (supplied by EMS-Griltech Corporation) were tested using a standard jacquard square procedure, and the results are provided in the table below.

[0077]

[0078] In addition to the first and second yarns used to form the knitted part 132, a third yarn may be used to form the third layer 158 of the knitted part 132. The third yarn may be the same as or different from the first and / or second yarns. In one example, the third yarn used to form at least a portion of the knitted part 132 comprises yarns different from the first and second yarns. In one example, the elasticity of the third yarn is relatively less than that of the first yarn (E04), and it may have the same, less, or greater elasticity as the second yarn (as described above, which may be monofilament and fusible). The third yarn may be a combination of materials or strands. One or more warp yarns of the third yarn may be used, such as one warp yarn, two warp yarns, or more than two warp yarns.

[0079] For example, the third yarn may comprise a combination of three warp yarns of a "monofilament" type yarn and one warp yarn of a "high-tenacity" type yarn. The monofilament yarn may have the same properties as the monofilament yarn used in the second yarn described above. Similar to the monofilament of the second yarn, the monofilament yarn of the third yarn may expand or have minimal shrinkage when stimulated (e.g., by temperature, heat, or steam). The high-tenacity yarn may be supplied by Far Eastern New Century in Taipei, Taiwan. The high-tenacity yarn is a polyester yarn that may comprise multiple yarn filaments and impart various aesthetic and color properties to the knitted part 132. The high-tenacity yarn has a melting point of approximately 210 degrees Celsius. The shrinkage rate of the third yarn (when exposed to steam or other stimuli), also known as the third shrinkage rate, may be lower than the first shrinkage rate of the first yarn, and may be larger, smaller, or equal to the second shrinkage rate of the second yarn used to form the knitted part 132 when exposed to heat or other stimuli. In other words, when subjected to a similar amount of heat (e.g., via temperature, heat, or steam), the third yarn may shrink much less (if any), have a lower shrinkage rate than the first yarn, and / or expand. Moreover, the third yarn may shrink relatively more, less, or the same as the second yarn. In one example, a combination of materials, such as monofilament yarns and high-tenacity yarns forming the third yarn together, can be achieved through parallel coexistence. In other embodiments, the combination of materials can be achieved through twisting, winding, braiding, and / or wrapping on one another, and / or the yarns may be in a core / sheath configuration, and / or the yarns may be secured at multiple points along their length. In one example, the shrinkage rates of a 0.125mm monofilament yarn (supplied by Hi-Tech Corporation of Korea) and a high-tenacity yarn (supplied by Far East New Century Corporation) were tested using a standard jacquard square procedure, and the results are provided in the table below.

[0080]

[0081] During or after the knitting process, a heat stimulus, such as thermal stimulation, may be applied to at least a portion or the entire upper 102. This heat may be in the form of steam, for example, via a steam gun or other steam supply device. Exposure of the knitted portion 132 to steam 166 may produce one or more effects.

[0082] In one example, steam 166 can cause one or more yarns used to form the knitted part 132 to shrink at different relative rates, thereby forming a raised structure 128, such as... Figure 4 As shown. For example, steam 166 can cause the first yarn (e.g., E04 yarn) to shrink to a greater extent and / or rate than the second and third yarns used to form the knitted part 132. In one example, the second yarn (e.g., monofilament and fusible yarn) may also shrink in response to the stimulation of steam 166, but less than the first yarn. The second yarn has a relatively small or insignificant shrinkage in response to the stimulation, and may also expand when stimulated. The third yarn (e.g., monofilament and high-tenacity yarn) also has a relatively small or insignificant shrinkage in response to the stimulation of steam 166, and may also expand when stimulated. The shrinkage rates and potential expansion of the first, second, and third yarns can result in the total shrinkage rate of the knitted part 132. In one example, after the application of stimulation, the total shrinkage rate of the knitted part 132 includes an average shrinkage rate of 10% along the length (x: toe to heel) and an average shrinkage rate of 14.25% along the width (y: back to front).

[0083] like Figures 3 to 5 As shown, the first yarn forming the first knitted layer 154 can be used to form at least a portion of the first side 134 of the knitted component 132, and thus form the inner surface of the upper 102 (e.g., facing the cavity) at the pod 160 (and below the protrusion 128) of the upper 102. The first yarn can also be used to form at least a portion of the second side 136 of the knitted component 132, thereby forming the outer surface of the upper 102 at the second region 130. The second yarn forming the second knitted layer 156 can be used to form at least a portion of the second side 136 of the knitted component 132, which forms the outer surface of the upper 102 at the pod 160 or the protrusion 128 of the upper 102. The second yarn can also be used to form at least a portion of the first side 134 of the knitted component 132, which forms the inner surface of the upper 102 at the second region 130. Before exposing the knitted component 132 to stimulation (see Figure 3 The second side 136 may be generally flat, overlapping, and generally extend along with the first side 134. Alternatively, the protruding structure 128 of the pod 160 may be partially visible before the knitted part 132 is exposed to stimulation, such as... Figure 3As shown (for example, due to the use of more loop rows than the first side 134 to form the second side 136 during knitting), but not as Figures 4 to 5 As clearly and / or limited as shown, Figures 4 to 5 An example of a knitted component 132 after exposure to a stimulus is shown. When exposed to a stimulus such as steam 166, the first yarn of the first knitted layer 154 shrinks, while the second yarn on the second knitted layer 156 and the third yarn on the third layer 158 of the knitted component 132 each have relatively small or insignificant shrinkage. In one example, the second yarn of the second knitted layer 156 and the third yarn of the third layer 158 can expand. The shrinkage of the first yarn causes the second yarn to expand as... Figures 5 to 6 and Figure 4 The arrows indicate outward bending or protrusion to form a raised structure 128 extending outward and away from the first side 134 of the knitted part 132. The expansion of the second and third yarns also enhances the bending / protrusion of the second side 134 when they expand. In other words, the relative difference in shrinkage and expansion rates of the different yarns used to form the knitted part 132 upon exposure to stimuli results in the formation or enhancement of the raised structure 128.

[0084] like Figures 3 to 5 As shown, more than one third yarn can form the third layer 158 of the knitted component 132. In one example, in Figures 3 to 5 In the side cross-sectional view, two strands of the third yarn forming the third layer 158 include a first portion 158a and a second portion 158b of the third yarn. When viewed from the side cross-sectional view, these two strands of the third yarn may cross each other and form an "X" configuration within the pod 160 or protrusion 128. In one instance, the first portion 158a and the second portion 158b of the third yarn have the same characteristics, or in another instance, the first portion 158a and the second portion 158b of the third yarn may have the same or similar characteristics, except for one or more characteristics, such as color. Figures 3 to 5 As shown, the first portion 158a and the second portion 158b of the third yarn float through the knitting component 132 within the second region 130. In this embodiment, they are therefore not fixed to the first layer 154 and the second layer 156 within the second region 130. However, alternatively, the third yarn 158 may form interlocking loops at least partially within the second region 130.

[0085] Within the pod 160 or the protrusion 128, the third yarn may be secured to the first layer 154 and the second layer 156 via a tucked structure and / or a loop. A first portion 158a of the third yarn may be secured to a portion of the second layer 156 at a second position 164a via a tucked structure and / or a loop, and a second portion 158b of the third yarn may be secured to a portion of the first layer 154 at a first position 162a via a tucked structure and / or a loop. The first and second portions 158a and 158b of the third yarn then cross each other within the pocket of the clip 160. The first portion 158a may then be secured to a portion of the first layer 154 at a third position 162b via a tucked structure and / or a loop, and the second portion 158b may be secured to a portion of the second layer 156 at a fourth position 164b via a tucked structure and / or a loop. By securing the third yarn to the first layer 154 and the second layer 156 via a tufted structure and / or loops, the placement and positioning of the third layer 158 within the pod 160 are ensured.

[0086] As described above, in one example, the second yarn may be translucent or transparent (at least after a stimulus, such as heat treatment, is applied to the knitted part 132), and the third yarn may have a color visible on the outer surface of the upper 102 through the raised structure 128. The positioning of the third yarn within the raised structure 128 is variable, such that the color of the third yarn is visible at different viewpoints on the outer surface of the upper 102. For example, a first portion 158a of the third yarn may have a different color than a second portion 158b of the third yarn, such that the color of the first portion 158a is visible through the outer surface of the upper 102 at one viewpoint or position, and the color of the second portion 158b is visible through the outer surface of the upper 102 at different viewpoints or positions. Thus, through the selective positioning of the third yarn, including the third yarn being secured to the second layer 156 within the pod 160 and the raised structure 128, different colors are visible through the outer surface of the upper 102.

[0087] Now go to Figure 6 and Figures 7A to 7B The following describes a knitting process for forming a knitted component 132, which includes one or more pods 160 to form a raised structure 128 and a second region 130. First, Figure 6 An annotated top view of the knitted component 132, reflecting the second side 136 (which forms the outer surface of the upper 102 when the knitted component 132 is incorporated into the footwear article 100). The adjacent portions “1” and “2” of the knitted component 132, depicted in pink (e.g., dashed lines in the black and white drawing), correspond to… Figure 7AThe diagram shows an exploded view of the knitting process. This section will be referred to herein as section 1-2. The adjacent sections "3" and "4" of knitted part 132, depicted in blue (e.g., solid black lines in the black and white accompanying drawings), correspond to... Figure 7B The diagram shows an exploded view of the knitting process. This section will be referred to herein as Section 3-4. Sections 1-2 and 3-4 together reflect the formation as described above and as shown below. Figure 5 The pod 160 of the protruding structure 128 is shown in an offset configuration. In addition to the pod 160 described herein, portions 1-2 also reflect a second region 130. Portions 3-4 reflect the two halves of the adjacent pod 160, with the second region 130 located between the two halves of the adjacent pod 160. In other words, with... Figure 3 In comparison, parts 3-4 show that in Figure 3 The middle second region 130, and the left half of the pod 160 and the right half of the pod 160 in the second region 130.

[0088] exist Figure 6 In the diagram, light green yarn (shown as light gray in the black and white image) reflects the yarn of the second layer 156, which forms part of the second side 136 of the knitted component 132 or the outer surface of the upper 102. Orange yarn (shown as black in the black and white image) reflects the yarn of the first layer 154, which forms part of the second side 136 of the knitted component 132 or the outer surface of the upper 102 at the second region 130 of the knitted component 132.

[0089] Turn Figure 6 and Figure 7A As shown in sections 1-2, knitting component 132 is formed by multiple rows and warps of loops. In weft knitting, the warps are perpendicular to the rows of loops of yarn. The warps of sections 1-2 and 3-4 within knitting component 132 are numbered 170-x, where "x" reflects the individual warps, specifically warps 1 to 12. In this example, the number of warps is the same as the number of needles in the needle bed of the knitting machine. Figures 7A to 7B The middle part is represented by a dot. For example... Figure 7A As shown, the loop rows of portions 1-2 within the knitting component 132 are numbered "172-x", where "x" reflects the individual loop rows, specifically loop rows 1 to 16. In this embodiment, to generate a loop row, such as 172-1, two passes are performed on the knitting machine, for example, from left to right and then from right to left along the needle bed of the knitting machine. As described above, in an alternative embodiment, a loop row can be generated by a single pass on the knitting machine (e.g., from left to right or from right to left). Figure 6 and Figure 7AIn the example shown, sections 1-2 are formed by 16 rows of loops and 12 rows of loops. The 16 rows of loops create 8 rows on the first side 134 of the knitted part 132 and 8 rows on the second side 136 of the knitted part 132. The 8 rows on the second side 136 of the knitted part 132... Figure 6 The diagram shows and labels "row x", where x reflects the corresponding row from row 1 to row 8. In an alternative embodiment, the number of coil rows can be reduced to decrease the size of the pod 160, or the number of coil rows can be increased to increase the size of the pod 160. In other words, when the pod 160 forms a generally spherical protrusion 128 having a first diameter extending along a first direction A and a second diameter extending along a second direction B, the number of coil rows can be reduced to decrease the second diameter of the protrusion 128, or the number of coil rows can be increased to increase the second diameter of the protrusion 128. Moreover, in this example, the number of coil rows in each pod 160 can be reduced to decrease the first diameter of the protrusion 128, or increased to increase the first diameter of the protrusion 128.

[0090] exist Figure 7A In this process, a first loop row 172-1 is formed of the knitted component 132 to create a first portion of the second layer 156 of the knitted component 132, and a second loop row 172-2 is formed of the knitted component 132 to create a first portion of the first layer 154-1 of the knitted component 132. The first portion of the second layer 156 is in... Figure 7A The middle is marked as 156-1, and the first part of the first layer 154 is in Figure 7A The first pass of the first loop row 172-1 is marked as 154-1. During the first pass of the first loop row 172-1, the second layer 156-1 is knitted using every other needle on the front needle bed of the knitting machine. During the second pass of the first loop row 172-1, the second layer 156-1 is knitted using every other needle on the front needle bed of the knitting machine (specifically, needles skipped during the first pass of the first loop row 172-1), except for the first needle shown in the first loop warp 170-1 of the first loop row 172-1, which is knitted on the first needle on the first needle of the back needle bed of the knitting machine (e.g., by knitting loops 180 of the first loop row 172-1 on the back needle bed). More than two passes of the first loop row 172-1 can be utilized (e.g., to form more knitted material on the second side 136 of the knitted part 132 to enhance the bulkiness of the raised structure 128).

[0091] During the first pass of the second loop row 172-2, the first layer 154-1 is knitted using every other needle on the back needle bed of the knitting machine. During the second pass of the second loop row 172-2, except for the first needle shown in the first loop warp 170-1 of the first layer 154-1 knitted on the first needle of the front needle bed of the knitting machine (e.g., by knitting the loop 182 of the second loop row 172-2 on the front needle bed at the position corresponding to the loop 180), the first layer 154-1 is knitted on the back needle bed of the knitting machine using every other needle (specifically, the needles skipped during the first pass of the second loop row 172-2). Anchoring the first layer 154-1 and the second layer 156-1 formed on the front and back needle beds allows the creation of the aforementioned second region 130, which separates the individual pods.

[0092] When the first layer 154-1 is knitted on the front needle bed and the second layer 156-1 is knitted on the back needle bed, a portion of one of the second regions 130 is formed such that the first layer 154-1 forms a portion of the second side 136 of the knitted part 132 (and the outer surface of the upper 102), and the second layer 156-1 forms a portion of the first side 134 of the knitted part 132 (and the inner surface of the upper 102). Therefore, within a portion of the second region 130, the first layer 154-1 and the second layer 156-1 are fixed to each other, and the third layer 158 floats between the first layer 154 and the second layer 156 (as described below).

[0093] like Figure 7A As shown, in order to form a third layer 158 positioned between the first layer 154-1 and the second layer 156-1, two passes on the knitting machine are also completed (e.g., from left to right and from right to left). This portion of the third layer 158 is... Figure 7AThe yarn is marked 158-1. In the first pass, the yarn of the third layer 158-1 floats through the first three needles, then gathers on the fourth needle onto the back needle bed to secure the third layer 158-1 to the first layer 154-1 of the knitting part 132 at the first position 162a. The yarn of the third layer 158-1 then floats through the fifth to ninth needles, then gathers on the tenth needle onto the front needle bed to secure the third layer 158-1 to the second layer 156-1 at the second position 164a. The yarn of the third layer 158-1 then floats through the eleventh and twelfth needles to complete the first pass. In the second pass, the yarn of the third layer 158-1 again floats through the twelfth to eleventh needles, then gathers on the tenth needle onto the back needle bed to secure the third layer 158-1 to the first layer 154-1 at the third position 162b. Then the yarn of the third layer 158-1 floats through the ninth to fifth needles, and then gathers on the fourth needle to the front needle bed to secure the third layer 158-1 to the second layer 156-1 of the knitting part 132 at the fourth position 164b. Then, the yarn of the third layer 158-1 floats through the third to the first needle to complete the second pass. The two passes within the pod 160 produce a... Figures 3 to 5 The third layer 158-1 is shown in an "X" configuration. In an alternative embodiment, the position of the yarn of the third layer 158-1 fixed to the first layer 154-1 or the second layer 156-1 may vary.

[0094] After knitting the first loop row 172-1 and the second loop row 172-2, and allowing the third layer 158-1 to float through and be secured to the first layer 156-1 and the second layer 154-1 via a tuck stitch, the third loop row 172-3 of the knitted part 132 forms the second portion of the second layer 156 of the knitted part 132, and the fourth loop row 172-4 of the knitted part 132 forms the second portion of the first layer 154 of the knitted part 132. The second portion of the second layer 156 is... Figure 7A The middle part is marked as 156-2, and the second part of the first layer is in Figure 7A The middle section is marked 154-2. In the first pass of the third loop row 172-3, the second layer 156-2 is knitted using every other needle on the front needle bed of the knitting machine. In the second pass of the third loop row 172-3, the second layer 156-2 is knitted using every other needle (specifically, the needles skipped in the first pass of the third loop row 172-3). Compared to the first portion of the second layer 156-1 knitted in the first loop row 172-1, the second portion of the second layer 156-2 knitted in the third loop row 172-3 is knitted only on the front needle bed of the knitting machine.

[0095] In the first pass of the fourth loop row 172-4, the first layer 154-2 is knitted using every other needle on the back needle bed of the knitting machine. In the second pass of the fourth loop row 172-4, the first layer 154-2 is knitted using every other needle on the back needle bed of the knitting machine (specifically, the needles skipped in the first pass of the fourth loop row 172-4). Compared to the first portion of the first layer 154-1 knitted in the second loop row 172-2, the second portion of the first layer 154-2 knitted in the fourth loop row 172-4 is knitted only on the back needle bed of the knitting machine. In this example, the second portion of the first layer 154-2 and the second portion of the second layer 156-2 are not fixed to each other at the first needle of the knitting machine. Moreover, in this example, the third layer 158 is not fixed to the second portion of the first layer 154-2 or the second portion of the second layer 156-2. In other embodiments, the second portion of the first layer 154-2 and the second portion of the second layer 156-2 may be fixed to each other. Furthermore, in other embodiments, the third layer 158 may be fixed to the second portion of the first layer 154-2 and the second portion of the second layer 156-2.

[0096] like Figure 7A As shown, the pattern of knitting the first loop row 172-1, the second loop row 172-2, the third loop row 172-3, and the fourth loop row 172-4, and floating the third layer 158-1 and fixing it to the first layer 154-1 and the second layer 156-2 via a tuck stitch, is then repeated in the fifth to eighth loop rows (172-5, 172-6, 172-7, 172-8), the ninth to twelfth loop rows (172-9, 172-10, 172-11, 172-12), and the thirteenth to sixteenth loop rows (172-13, 172-14, 172-15, and 172-16).

[0097] The first coil row 172-1 and the second coil row 172-2 each generate as follows: Figure 6 The second side 136 of the knitted part 132 shown represents a portion of the first row or "row-1" of the first row, and a portion of the first side 134 of the knitted part 132. The third loop row 172-3 produces... Figure 6 The second row, or "row-2", of the second side 136 of the knitted part 132, and the fourth loop row 172-4 produce the second row of the first side 134 of the knitted part 132. As described above, the repeated knitting pattern forms sixteen loop rows, with 8 rows formed on the first side 134 of the knitted part 132 and 8 rows formed on the second side 136 of the knitted part 132, as shown. Figure 6As shown. Moreover, as mentioned above, in alternative embodiments, the number of coil rows and corresponding rows can be reduced to decrease the size of the pod 160 (and therefore the protrusion structure 128), or increased to increase the size of the pod 160 (and therefore the protrusion structure 128).

[0098] exist Figures 7A to 7B In the diagram, light green yarns (shown as rows of white loops in the black and white image) reflect the yarns of the second layer 156, which forms part of the second side 136 of the knitted component 132 or the outer surface of the upper 102 at the pod 160, and part of the first side 134 of the knitted component 132 or the inner surface of the upper 102 at the second region 130. Orange yarns (shown as closely spaced left-leaning hash lines in the black and white image) and blue yarns (shown as right-leaning hash lines in the black and white image) reflect the yarns of the first layer 154, which forms part of the second side 136 of the knitted component 132 or the outer surface of the upper 102 at the second region 130. At the pod 160 of the knitted component 132, orange yarns (left-leaning hash lines) and blue yarns (right-leaning hash lines) form part of the first side 134 of the knitted component 132 or the inner surface of the upper 102. Dark green (shown as wide-spaced left-leaning hash lines in a black-and-white diagram) and red yarn (shown as solid dark gray in a black-and-white diagram, adjacent to dark green (e.g., wide-spaced left-leaning hash lines)) reflect the yarn of the third layer 158 located between the first layer 154 and the second layer 156 of the knitted part 132.

[0099] As described above, portions 1-2 reflect the second region 130 and the pod 160, which together form part of the knitted component 132. Figure 6 and Figure 7B As shown, portions 3-4 form part of the subsequent row of the knitted component 132. However, as Figure 6 As shown, the orange yarns (displayed as closely spaced left-leaning scattered lines in the black and white diagram) of the second region 130, reflecting the first layer 154 knitted on the front needle bed and the second layer 157 knitted on the back needle bed, are roughly positioned at the center of section 3-4. This configuration reflects the offset configuration of the pod 160 (forming the raised structure 128), as... Figure 5 As shown. Therefore, the knitting sequence of POD3-4 differs from that of parts 1-2 in two aspects. First, the first layer 154 is... Figure 7B The seventh stitch, as shown in the seventh row 170-7, is at the seventh needle position, not at... Figure 7A At the first needle position shown in the first row 170-1, the knitting transitions from the back needle bed to the front needle bed. Secondly, the second layer 156 is at the seventh needle position shown in the seventh row 170-7, not at... Figure 7AThe first loop 170-1 is at the first needle position shown in part 1-2, where knitting switches from the front needle bed to the back needle bed. As previously described, this knitting sequence produces a second region 130, such that the second region is formed approximately in the center of part 3-4 rather than at the beginning of part 1-2. Except for the differences described above, the knitting sequence and characteristics used to describe part 1-2 also apply to part 3-4.

[0100] exist Figure 6 In the illustrated example, the second region 130 demarcates the pod 160 along its left and right sides, in other words, along the wale direction or second direction B of the knitted member 132. The second region 130 does not demarcate the entire top and bottom sides of the pod 160, or along the transverse direction or first direction A of the knitted member 132. Instead, the second region 130 forms fixed points along the top and bottom sides of the pod 160. In an alternative embodiment, the second region 130 may also extend along the entire top and / or bottom sides of the pod 160, or along the transverse direction A of the knitted member 132, such that the pod 160 is surrounded by the second region 130 on each side of the pod 160.

[0101] Repeat if necessary Figures 7A to 7B The knitting sequence is chosen to form knitted parts of suitable size. Furthermore, it should be noted that the sequence can be altered to incorporate different characteristics by changing certain knitting structures, by changing the yarn type, by increasing or decreasing the number of loops in each step, or by making any other appropriate adjustments to the knitting process or the materials used. Additionally, it is possible to... Figures 7A to 7B Use other orders before, after, or between them.
