Description

Article with multiple layers and manufacturing method thereof

Various objects are formed from textiles. For example, clothing items (e.g. shirts, shorts, socks, footwear, jackets and other outerwear, underpants and other underwear, hats and other headwear), containers (e.g. backpacks, bags) and interior accessories for furniture ( (Eg chairs, benches, car seats) are usually formed at least partially from textiles. These textiles are usually formed by weaving or bundling (e.g., weaving) a yarn or a plurality of yarns, usually by a mechanical process involving a loom or a weaving machine. A specific article that can be formed from a textile is used for an upper of an article of footwear. Conventional footwear items generally include two main components: an upper and a sole structure. The upper is fixed to the sole structure and forms a space for comfortably and securely holding one foot inside the article of footwear. The sole structure is fixed to a lower surface of one of the uppers to be positioned between the upper and the ground. For example, in some sports footwear items, the sole structure may include a midsole and an outsole. The midsole may be formed from a polymer foam material that reduces ground reaction forces to reduce stress on the feet and legs during walking, running, and other walking activities. The outsole can be fixed to a lower surface of one of the midsoles and forms a ground engaging portion of the sole structure, which is formed of a durable and wear-resistant material. The upper of the footwear generally extends above the instep and toe areas of the foot along the inside and outside of the foot and around the heel area of the foot. Access to the interior of the upper is generally provided by an ankle opening in one of the heel areas of the footwear. A shoelace system is usually incorporated into the upper to adjust the fit of the upper, thereby facilitating the entry of the foot from the space in the upper and the removal of the space from the upper. In addition, the upper may include a tongue that extends below the lace system to enhance the adjustability of the footwear, and the upper may incorporate a heel stabilizer to limit heel movement.

Various aspects are described below with reference to drawings in which the same elements are generally identified by the same symbols. The relationship and functions of various elements of the aspect can be better understood by referring to the following [embodiments]. However, the aspects are not limited to such aspects as shown 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 that are not necessarily used to understand the aspects disclosed herein, such as conventional manufacturing and assembly, may be omitted. Certain aspects of the invention relate to objects formed at least partially from textiles. An example of an item is an item of clothing (such as shirts, shorts, socks, footwear, jackets and other outerwear, underwear and other underwear, hats and other headwear, or the like). The article may be structurally designed for one of the uppers of an article of footwear. The upper can be used with any type of footwear. Illustrative non-limiting examples of footwear include a basketball shoe, a bicycle shoe, a cross training shoe, a football (soccer) shoe, an American football shoe, a bowling shoe, a golf shoe, a mountaineering shoe, One ski or snowboard boot, one tennis shoe, one running shoe, and one walking shoe. The upper may also be incorporated into a non-sport shoe, such as a gift shoe, a flat shoe, and a sandal. Referring to FIG. 1, an article of footwear 100 is generally depicted as including a sole 110 and an upper 120. The upper 120 includes an outer side 104 and an inner side 105. The area where the sole 110 engages the shoe of the upper 120 may be referred to as the bite line 116. The upper 120 may be joined to the sole 110 in a fixed manner using any suitable technique, such as by using an adhesive, by stitching, or the like. It is contemplated that the upper 120 may extend partially or completely around a wearer's foot and / or may be integrated with the sole, and may or may not use an insole. In some embodiments, sole 110 includes a midsole (not shown) and an outsole. The article of footwear 100 may additionally include a throat 126 and an ankle opening 128 that may be surrounded by a collar 130 and may result in a space 132. The space 132 of the article of footwear 100 may be structurally designed to accommodate one person's foot. The throat 126 is generally disposed in the midfoot region 102 of the upper 120. The midfoot region 102 is generally an area of the upper 120 positioned between a heel region 101 and a toe region 103. In some embodiments, a tongue may be placed in the throat 126 of the shoe, but a tongue is an optional component. The tongue can be any type of tongue, such as a tongue with a triangular gusset or a roll of tongue. If a tongue is not included, the outside and inside of the throat 126 can be joined together. Although not shown, in some embodiments, article of footwear 100 may include an optional fastening element, such as a shoelace (which may be associated with shoelace aperture 136). Any suitable type of fastening element may be used. As depicted in FIG. 1, the upper 120 may include a base layer 140, which is depicted herein as a textile layer, but the base layer is not necessarily limited to the textile material. The base layer 140 may be formed of a woven material, a fabric material, one or more mesh layers, a solid material, and / or any other suitable material. The base layer 140 may include one or more threads, threads, yarns, mesh components, or the like (referred to herein as a "yarn"). The base layer 140 may have a first side forming an inner surface of the upper 120 (eg, a space 132 facing the article of footwear 100) and a second side forming an outer surface of the upper 120. In some embodiments, another object or layer (such as a buffer layer) may be included between the space and the base layer 140. The base layer 140 may be formed as an integral one-piece element. For example, the base layer 140 may be formed during a single weft knitting procedure (e.g., using a flat or circular knitting machine), a warp knitting procedure, or any other suitable knitting procedure such that the knitting procedure does not require significant post-knitting procedures or steps A substantially woven structure of the base layer 140 is formed below. Although not shown, in some embodiments, the base layer 140 of the upper 120 may be structurally designed to substantially surround a wearer's foot such that it extends below the sole (also referred to as the sole or the bottom surface of the foot). In some embodiments, the upper 120 may include a second layer 150. Although not limited to including a mesh, the second layer 150 is depicted as a mesh layer. As used herein, a "mesh layer" may include, but is not limited to, an open mesh fabric or layer formed from yarns that are stringed, twisted, knotted, or woven together at specific intervals, and may be relative to A typical woven fabric and / or base layer 140 has a relatively low stitch density (ie, the number of loops per measurement area). In some exemplary embodiments, the second layer 150 is formed on a weaving machine. As depicted, the second layer 150 may have one or more regions exhibiting different functions and / or visual characteristics (e.g., a first region 152, a second region 154, a third region 156, and a fourth region 158, (As shown in Figure 2). Each "area" of the second layer 150 may be associated with one of the "zones" of the upper 120 (i.e., in this context, an "area" alone refers to one layer, and a "zone" refers to the upper or other object). The second layer 150 may be formed as an integral one-piece element. In some embodiments, the second layer 150 and the base layer 140 are formed together as a unitary one-piece element (which may be referred to as a "knit component") and may be formed by a single knitting process on a knitting machine. For example, the base layer 140 and the second layer 150 may be simultaneously and / or integrally formed on a multi-bed flat knitting machine. The second layer 150 is depicted as being positioned on one outer surface of the upper 120, but it is contemplated that the second layer 150 may be positioned at least partially on the other surface, such as the inner surface. In addition, the second layer 150 may have a boundary dimension substantially the same as that of the base layer 140 such that substantially all of at least one surface of the base layer 140 is covered by the second layer 150. Alternatively, and as depicted by FIG. 1, the second layer 150 may not be present in one of the isolation regions (the fifth region 142) of the base layer 140. Although not shown, it is also contemplated that the article of footwear 100 may have one or more locations in which the second layer 150 is present but no base layer 140 is present. FIG. 2 shows the upper 120 of the isolated article of footwear 100 (the article of footwear 100 of FIG. 1), and potentially, the shoe upper 120 after it is formed (eg, on a knitting machine) and with the article of footwear 100 Other elements (such as sole 110) will be presented before combination. During substantially a single process (eg, a single knitting procedure), the upper 120 may be formed as a unitary one-piece element. The upper 120 is shown as having four zones including the second layer 150, with each zone being associated with one of the four zones 152, 154, 156, and 158 of the second layer 150. The first region 152 of the second layer 150 may include a relatively large structure (eg, a relatively large unit 160 as described in more detail below). For example, this structure can provide the upper 120 with a desired level of support and elasticity. The second region 154 of the second layer 150 may have a relatively dense structure (eg, a relatively small unit 160). This structure may be relatively rigid and / or inelastic (at least relative to the first region 152) in areas where the upper 120 is required for support, strength, durability, and / or other specific properties associated with a coherent structure. It can be advantageous. In some embodiments, the first region 152 may have a first elasticity, and the second region 154 may have a second elasticity, so that when the same tensile load is applied to two regions, it has one of the first regions 152 The zone extends at least 5%, at least 10%, at least 20%, at least 50%, or even at least 100% (or more) than one zone having the second region 154. As shown, it may be advantageous for the second region 154 of the second layer 150 to extend from the bite line 116 to the throat 126 and / or one of the shoe mouth regions 127 adjacent to the throat 126, which may provide durability and structure Integrity is provided to a region that collectively experiences a high and high frequency stress during the typical use of an article of footwear. Further, the second region 154 may interact with a fastening element, such as a shoelace, to ensure that one of the uppers 120 fits snugly and comfortably. For example, tightening the lace may tighten the second region 154 (and its associated zone) around the foot. Similarly, the third region 156 (which is depicted as including one of the regions of the second layer 150 having two structures (described in more detail below)) may exhibit increased strength and durability relative to other regions and a reduced The amount of elasticity and / or may provide a desired visual effect. The fourth region 158 may have another structure (or a structure that is substantially the same as a structure from another region) for achieving the desired characteristics in that zone of the upper 120. Although four regions of the second layer 150 have been illustrated for explanation purposes, the second layer 150 may have more or less than four regions. A fifth region 142 of the base layer 140 may include a portion of the base layer 140 that is isolated from the second layer 150 and is not covered by the second layer 150. In this embodiment, the second layer 150 terminates at the edge of the fifth region 142, but it is expected that the structure of the second layer 150 can be dropped or otherwise slowly transitioned from the fourth region 158 to a transition zone. The fifth area 142. The fifth region 142 may be extended by at least 20%, at least 50%, at least 100%, at least 200%, or even at least 300% (or more) than at least one of the zones incorporated into one of the regions of the second layer 150 Big). It may be advantageous to include a fifth region 142 of the base layer 140 and / or other uncovered, isolated regions where flexibility, elasticity, and certain other characteristics that may be primarily associated with the isolated base layer 140. FIG. 3 shows an article 300 having a second layer 350 and an underlying substrate layer 340 according to an embodiment. The second layer 350 may have a first yarn portion 352, a second yarn portion 354, and a third yarn portion 356, each of which is depicted as extending in a substantially parallel direction in a serpentine pattern. These yarn portions may be formed from different materials or the same material, and it is contemplated that they may be formed from the same continuous yarn or separated yarns. As shown in FIG. 3, the first yarn portion 352 of the second layer 350 may be entangled with at least another yarn portion, such as the second yarn portion 354. In this embodiment, the second yarn portion 354 is entangled with the other two yarn portions (the first yarn portion 352 and the third yarn portion 356). It is contemplated that one yarn may be tangled with more than two yarns of the second layer 350. As shown, the structure defining unit 360 of the second layer 350 may have a corner defined at a point where the yarn portions of the second layer 350 are tangled and / or overlapped. The structure of the second layer 350 may form any suitable number of cells 360. Cell 360 is depicted in FIG. 3 as being substantially quadrilateral (ie, a four-sided polygon, such as a square or rectangle), but it is contemplated that second layer 350 may include cells having different shapes with different numbers of sides. For example, the second layer 350 may be formed with a triangular unit, a pentagonal unit, a hexagonal unit, and the like. In addition, the second layer 350 may have different regions containing a different property (such as different cell size or shape), and it is expected that the second layer 350 may have a pattern forming one of the cells of different shapes adjacent to each other. The shape of the unit 360 may be selected for certain characteristics. For example, a cell having a triangular shape may have a resilience different from one of the quadrangular cells in at least one direction. The size of the unit 360 may also be selected for certain properties. For example, a small unit may form a more compact, more rigid, and less resilient structure than a structure formed by a larger unit. The unit 360 may change size when using the object 300 in response to the movement and / or stretching of the object 300. The base layer 340 and the second layer 350 may have different functions and / or visual characteristics. For example, the base layer 340 may be more elastic than the second layer 350. The difference in elasticity may be by using yarns formed from different materials and / or having different sizes, by changing the way the yarns interact (e.g., by choosing to exhibit a specific elasticity of a particular knitted structure), or the like. A combination to achieve. In some embodiments, the base layer 340 and the second layer 350 may additionally or alternatively have varying degrees of strength, durability, thermal resistance, fluid (e.g., water or air) permeability, weight, flexibility, or Similar. In addition, the second layer 350 may have different visual properties (for example, a different color) than the base layer 340 so that the combination of the second layer 350 and the base layer 340 is beautiful. It is contemplated that when using the article 300 (eg, as an upper of an article of footwear), its movement may cause the second layer 350 to move visually relative to the underlying base layer 340, which may produce a desired visual effect. The yarns of the second layer 350 and the base layer 340 may be formed of any suitable material. For example, in some embodiments, the yarn forming the second layer 350 may be formed from a material that is relatively inelastic when compared to the yarn forming the underlying substrate layer 340. To illustrate, when subjected to the same tensile load, the yarns forming the base layer 340 may be extended by at least 5%, at least 50%, at least 100%, or even at least 500% more than the yarns forming the second layer 350 (and Potentially greater than 500%). The combination of the base layer 340 and the second layer 350 may be advantageous for achieving a desired combination of one of the characteristics of the object 300. For example, the base layer 340 may be relatively soft and abrasion-resistant, and the like may be a property designed to contact an upper surface of a wearer's shoe or an inner surface of another object. The base layer 340 can also be relatively elastic, which, for example, when used on an upper, can promote a snug and comfortable fit around the wearer's feet. The second layer 350 (which may be positioned on an outer surface of the base layer 340) may be relatively inelastic to penetrate the entire upper or provide structural integrity and durability to the upper at selected locations. FIG. 4 shows an embodiment of an object 400 in which a second layer 450 includes two structures (depicted as a first structure 452 and a second structure 454). As depicted, the first structure 452 and the second structure 454 each form their own unit. It is contemplated that more than two structures may be included. The first structure 452 and the second structure 454 are depicted as being substantially the same, but this is not required. In some embodiments, the first structure 452 may have characteristics (visual characteristics or functional characteristics) that are different from the second structure 454. The yarns forming the first structure 452 may or may not be stringed with the yarns forming the second structure 454. Both of the structures may be attached to the base layer 440, but alternatively, one or both of the structures may have a portion that is free from the base layer 440 (eg, loose relative to the base layer 440). The first structure 452 may be interlocked with the second structure 454. In other words, when the first structure 452 and the second structure 454 are viewed from the viewpoint shown in FIG. 4, in some positions, the first structure 452 may be located in front of the second structure 454 (for example, closer to the viewer), and In other locations, the first structure 452 may be located behind the second structure 454 (eg, closer to the base layer 440). As depicted, the cells of the first structure 452 may be offset from the cells of the second structure 454. FIG. 5 shows an object 500 having a second layer 550. The second layer 550 has three different regions: a first region 552, a second region 554, and a third region 556. A base layer 540 may include a fourth region 542, wherein the fourth region 542 of the base layer 540 may be isolated from the second layer 550. Two or more of the regions of the second layer 550 may have at least one different property. For example, in the first region 552, the second layer 550 has two structures (similar to that shown in FIG. 4). In the second region 554, the second layer 550 has a single structure containing one of the relatively larger cells. In the third region 556, the second layer 550 has relatively small cells when compared with the cells of the second region 554. The second layer 550 terminates in a fourth region 542 adjacent to the base layer 540 such that the fourth region 542 includes one of the uncovered and isolated portions of the base layer 540. The fourth region 542 may exhibit properties that are only associated with the base layer 540. FIG. 5 illustrates that the object 500 may have a different structure and thus have different functions and / or visual properties in different zones. Although all regions of the second layer 550 are depicted as being on the same side of the base layer 540, it is contemplated that at least one region of the second layer 550 may be on the opposite side of the base layer 540. In addition, it is contemplated that two or more regions of the second layer 550 may be spaced apart on the base layer such that an isolated region of the base layer 540 is disposed between these regions. As shown in FIG. 6, an object 600 may have a series of fastening yarns 642 at the corners of the unit and / or a series of fastening yarns 644 between the corners of the unit to attach to a substrate layer 640 a second layer 650. In some embodiments (not shown), a fastening yarn 642 may be included at each corner of each unit 660, but this is not required. The fastening yarn 642 can be selectively placed to achieve a specific fixed level between the second layer 650 and the base layer 640. In some instances, when it is desired that the second layer 650 remain substantially in the same position relative to the base layer 640, it may be advantageous to provide attachment at each corner. In other examples, it may be advantageous to allow several units of the second layer 650 to remain free relative to the base layer 640 (which may allow changing characteristics depending on the action of the object 600 and / or may allow each of several layers Mobile), which produces the desired visual and / or functional effect. It is further contemplated that some or all of the fastening yarns may be positioned at another location, such as between the corners of the cells of the second layer 650, as shown by the fastening yarns 644 of FIG. The fastening yarns 642 and / or 644 may be yarns forming the base layer 640. For example, as described in more detail below with reference to FIGS. 7-8, the yarn 652 (yarn 652 of FIG. 6) forming the second layer 650 may be integrated with the yarn (e.g., tangled) forming the base layer 640 during a weaving process ). However, it is contemplated that the fastening yarns 642 and / or 644 may be separated from the second layer 650 and the base layer 640, and / or may be embroidered and / or otherwise installed after the second layer 650 and the base layer 640 are formed. Other forms of attachment may be used additionally or alternatively. For example, the second layer 650 may be attached to the base layer 640 by an adhesive, using a short needle or mechanical clamp, by stitching or the like. FIG. 7 shows a diagram illustrating a method for forming an article having a base layer and a second layer on a knitting machine, wherein the knitting machine has a first needle bed 762 and a second needle bed 764. The first needle bed 762 may generally refer to a "front bed" on a flat knitting machine, and the second needle bed 764 may generally refer to a "rear bed" (or vice versa). The diagram of FIG. 7 is not intended to represent the entirety of an object, but is shown only to illustrate a particular sequence that is substantially repeatable. Each repetition of the depicted sequence need not be the same. In addition, Figure 7 shows only a series of six (6) consecutive needles for each needle bed, and it should be recognized that the additional needle repeats (potentially with some variation between the repeats) described across each needle bed may be step. Referring to FIG. 7, a first yarn 742 may be mainly associated with a base layer, and a second yarn 752 may be mainly associated with a second layer. Step A (which is not necessarily the first step of the sequence) shows a second yarn 752 knitted on one of the needles of the first needle bed 762 and then knitted on one of the needles of the second needle bed 764 separated by about two needles . This interval is not limited to two (2) needles, and it can be related to the size of the unit of the second layer. Steps B to E depict repeated weaving of the first yarn 742 on each of the plurality of needles of the second needle bed 764. This can form a base layer having a single plain weave structure. In the depicted embodiment, the first yarn 742 is completed four (4) times before the second yarn 752 is knitted again. The number of successive passes of the base layer can also be related to the cell size of the second layer. After weaving a portion of the base layer, the loop of the second yarn 752 positioned on one of the needles of the first needle bed 762 may be transferred to one of the needles of the second needle bed 764 in step F. Once the knitting process is continued, this may provide an attachment point between the second layer and the base layer (e.g., a point where a tethered yarn is positioned). Each of the four depicted loops of the second yarn 752 in FIG. 7 may be associated with a corner of a unit of the second layer. This sequence may be substantially repeated in steps G through K of FIG. 7, but as depicted, the sequence of the second yarn 752 at step G may be offset relative to step A. Here, this offset is shown equal to the distance between the six (6) needles of the first needle bed 762. When the knitting procedure is completed, this offset may correspond to one dimension of the unit. For example, the sequence described in FIG. 7 may form an object having a structure similar to that of the object 300 of FIG. 3. FIG. 8 shows a second layer having a base layer and a plurality of structures (for example, as shown in FIG. 4) formed on a knitting machine having a first needle bed 862 and a second needle bed 864. A diagram of an object and a method. A first yarn 842 may be mainly associated with a base layer, and a second yarn 852 and a third yarn 854 may be mainly associated with a second layer. The second yarn 852 may be primarily associated with a first structure of one of the second layers, and the third yarn 854 may be associated with a second structure of one of the second layers. In some embodiments, the second yarn 852 and the third yarn 854 may be substantially the same yarn, and it is contemplated that they may be the same continuous yarn. In the depicted step A, the second yarn 852 is knitted on one of the needles of the first needle bed 862 and then knitted on one of the needles of the second needle bed 864 separated by about 2 needles. Similarly, in step B, the third yarn 854 is depicted as undergoing the same sequence as the second yarn 852 but offset by one stitch. This offset may result in two structures with elements offset from each other (as best illustrated by FIG. 4). This offset is not limited to a needle, and it need not be constant throughout the entire object. In FIG. 8, steps C to F depict repeated knitting of the first yarn 842 on each of the plurality of needles of the second needle bed 864. This can form the described base layer with a single plain weave structure. After weaving a portion of the base layer, the loop of the second yarn 852 positioned on one of the needles of the first needle bed 862 may be transferred to one of the needles of the second needle bed 864 in step G. This can form an attachment point between the base layer and the second layer. Similarly, in step H, the loop of the third yarn 854 positioned on the first needle bed 862 may be transferred to the second needle bed 864. Referring to step I, the second yarn 852 may be knitted on one of the first needle bed 862 and the second needle bed 864 again. However, the second yarn 852 may be offset from its previous passes. For example, it may be offset from its previous pass by up to six (6) stitches, which may correspond to one of the dimensions of the several cells of the second layer. The unit size of the second layer can also be repeated with the base layer between the second yarn 852 and / or the third yarn 854 (e.g., a single plain weave pass from step C to step F and step K to step N ). Step J similarly involves weaving a third yarn 854 in a manner that was offset from its previous pass in step B. Steps K to N involve weaving the first yarn 842 of the base layer again to form a single plain weave structure. This weaving process can be repeated essentially to form a multi-structure (eg, one or two structures) region. The inventors have discovered that changing the structure of the second layer (as described herein) can achieve certain advantageous characteristics. For example, in a test, an object having one of five zones is formed according to the present invention. In this context, the zones of the object may be associated with a zone on a second level. A zone (such as a control zone) includes only one woven base layer and no second layer (ie, isolated from the second layer). The first zone includes a base layer and a second layer having a relatively large unit. The second zone, the third zone, and the fourth zone include a base layer and a second layer having a reduced cell size such that the fourth zone includes the smallest unit. Each of the zones forms a strip of approximately 1 inch by 6 inches. The zones are then individually tested using a test machine (i.e., an Instron 5965 test system) that applies a specific load and then loads at a speed of 50 millimeters per minute and at 75 Gage length in millimeters measures the elongation of each of several zones. Table 1 contains information recovered from these tests. Table 1 As shown in Table 1, elongation is related to cell size, with a smaller cell size reducing elongation. Advantageously, the cell size of one of the second layers as described herein can be selected to achieve specific elongation properties. In a second test, zones are tested to determine their recovery characteristics. In this test, a test machine (ie, an Instron 5965 test system) used a 100 Newton load to pull each of these zones for 100 cycles. The mark length is set to 100 mm. The displacement measurement (P ₀ ) was performed initially at approximately 9.8 Newtons and then again (P ₁ ) after 100 cycles. Table 2 contains information recovered from this test. The tensile recovery index is determined by dividing the difference between the initially measured length (P ₀ ) and the final measured length (P ₁ ) by the difference between the mark length and the initial length. Table 2 As indicated by the data, the cell size of the second layer is related to a lower tensile recovery index. Advantageously, the structure of the second layer as described herein may therefore be structurally designed to achieve specific restoration properties. For example, the second layer may provide a desired locking effect to a specific zone in, for example, a specific area of an article of footwear, while other zones may be structurally designed to have one of the relatively high degrees of freedom required for movement. Higher flexibility. In the above embodiments, when compared to a zone without a second layer, a zone with a second layer (e.g., a mesh layer) is generally described as having a relatively low elasticity and high tensile resistance. . However, it is also expected that a zone with a network layer may be relatively elastic when compared to other zones. For example, referring to FIG. 9, an object 900 may include a first zone 952 and a second zone 954. The first zone 952 has a first region 942 of a base layer 940 and a second layer 950, which may be similar to the embodiment described above. The first region of the base layer 940 may include a first yarn, and the second layer 950 may include a second yarn. The second yarn (s) of the second layer 950 may be relatively inelastic when compared to the first yarn (s) of the first region 942 underlying the base layer 940. The second layer 950 may use the method described above (e.g., by weaving the base layer on a first needle bed while holding the second yarn on a second needle bed, and then transferring the second yarn to the First needle bed), and may include any of the characteristics or other aspects described above with respect to a second layer. The second zone 954 of the object 900 may include a second region 944 of a base layer 940. The second layer 950 may terminate in the second region 944 adjacent to the base layer 940 so that it does not cover a surface of the second region 944. The second region of the base layer 940 may share at least one common yarn (eg, the first yarn) and / or at least one common weft with the first region of the base layer 940, and it is expected that the first region 942 and the second region are formed. The woven structure of the region 944 may be different. The second region 944 of the base layer 940 may also share at least one common yarn (eg, a second yarn) and / or at least one common weft with the second layer 950 positioned in the first region 942. In other words, the second region 944 of the base layer 940 may be formed at least in part by a yarn forming the first region 942 of the base layer 940 and a yarn forming the second layer 950. In some embodiments, this may result in the second region 944 of the base layer 940 having a higher stitch density relative to the first region 942 of the base layer 940 (ie, the total number of knitted loops in one of the measurement regions of the fabric) . Additionally or alternatively, the second region 944 of the base layer 940 may incorporate a second yarn (e.g., a yarn that at least partially forms the second layer 950), which may cause the second region 944 of the base layer 940 to be different from the base One of the first regions 942 of the layer 940 is elastic. Therefore, in some embodiments, the first zone 952 of the article 900 may include a relatively high elasticity when compared to the second zone 954 of the article. In other words, the first zone 952 may have a first degree of elasticity such that it has a first elongation when subjected to a tensile load, and the second zone 954 may have a second degree of elasticity such that it undergoes the stretching It has a second elongation under load. The first elongation may be, for example, at least 5%, at least 10%, at least 20%, at least 50%, or even at least 100% (or more) than the second elongation. The yarns of the second region 944 of the base layer 940 may be distributed such that the first yarns forming the first region 942 of the base layer 940 are mainly associated with an outer surface of one of the second regions 944 and / or such that the The second yarn of the second region 944 is primarily associated with an inner surface of one of the second regions 944 of the base layer 940 (or vice versa). Advantageously, from an external perspective, the second yarn may be hidden so that the first region 942 and the second region 944 of the base layer 940 may have a uniform appearance (which may be aesthetically desirable), while still exhibiting the above Describe the functional characteristics. Alternatively, the second yarn may be exposed (when associated with the outer surface) to create a contrast in appearance between the first region 942 and the second region 944 of the base layer 940. Alternatively, both the first yarn and the second yarn may be associated with both surfaces. Although not required, the article 900 may also include a third zone 956 having a third region 946 of a base layer similar to the first region 942 of the base layer 940 in the knitted structure and / or yarn composition. The second layer 950 may terminate in a third region 946 adjacent to the base layer 940 such that the third region 946 of the base layer 940 is isolated from other layers in the third zone 956. Therefore, the third zone 956 may have a relatively high elasticity when compared to the first zone 952 and the second zone 954, and accordingly may be better than the first zone 952 when subjected to a specific tensile load. And the elongation of the second zone 954 is extended by at least 5%, at least 10%, at least 20%, at least 50%, or even at least 100% (or more). Further, although not shown, it is contemplated that the second layer 950 may have multiple regions (similar to that described with reference to the object 500 of FIG. 5). Referring to FIG. 10, a knitted upper 1020 used for one article of footwear may have a first zone 1052, a second zone 1054, and a third zone 1056, which may have a first zone similar to that of FIG. Relative characteristics of the characteristics of zone 952, second zone 954, and third zone 956. The three zones can be positioned in any suitable location on the upper 1020. As shown, for example, the first zone 1052 may extend from an occlusion line 1016 to a shoe mouth area 1027 and may provide appropriate rigidity, durability, and structural support in that particular area. The second zone 1054 can be positioned in a heel area 1001, as shown, thereby providing the desired characteristics to that area. Additionally or alternatively, the second zone 1054 may be positioned in the shoe upper region 1027, which may be beneficial in providing sufficient rigidity, strength, and durability, where the upper 1020 is structurally designed to couple to a fastening element, such as a shoe band). The third zone 1056 can be positioned in a toe region 1003, which requires a relatively high elasticity for providing the comfort and desired performance of the footwear. The respective zones are shown in specific areas of the upper 1020 for non-limiting illustration purposes only, and it is expected that three zones (or more or less than three zones) may be relative to the upper 1020 by any Configured in a specific way.
