Description

[TECHNICAL FIELD ]

[0001] The present disclosure relates to a zonal stretchable integrated shoe upper including a leno weave and shoes including the same, and more particularly, to a zonal stretchable integrated shoe upper including a plurality of leno weaves and general weaves having each different stretchability, and shoes including the same.[BACKGROUND ART]

[0002] A shoe includes a sole which is a portion making contact with the ground, and a shoe upper which is coupled with the sole to cover the foot of a wearer.

[0003] The sole is coupled with a lower portion of the upper to protect a bottom surface of the foot from external environment and provide appropriate cushioning to provide comfort during walking or exercising.

[0004] The upper protects the foot and provides adequate ventilation to cool the foot and remove sweat. In order to satisfy various characteristics required for shoes, such as stretchability, breathability, wear resistance, resilience, and quick-drying, the upper is manufactured through various processes, such as removing certain portions or attaching appropriate materials.

[0005] In order to improve the manufacturing convenience and efficiency of shoes, the shoe upper may be woven as an integral piece. Details regarding such an integrally woven shoe upper are disclosed in detail in Korean Patent No. 10-1437472 (August 28, 2014). In addition, a loom for weaving a fabric including heterogeneous weaves, shoe uppers woven using the same, and shoes are disclosed in detail in Korean Patent No. 10-1557130 (September 24, 2015).

[0006] Regarding the stretchability of shoe uppers, Korean Patent No. 10-2338867 (December 8, 2021) discloses "Shoe upper with different stretchability of each part using fabric texture and a weaving method thereof." However, this patent has a shortcoming of failing to address breathability, which is one of the important characteristics of shoe uppers.

[0007] The shoe upper that makes up the shoe needs to have breathability and stretchability in portions where there is a lot of movement including bending such as the portion where the instep and toes meet (toe box), due to the characteristics of foot protection and foot movement. In addition, the side of the foot, such as a quarter portion and a heel portion, needs to have breathability and sturdiness rather than stretchability. To this end, stretchable fabric is used in portions where stretchability is required, and breathable mesh fabric is used in portions where breathability is required, and the shoes are completed by partially sewing or binding the same.

[0008] Mesh fabric, which is mainly used as a material with excellent breathability for shoe uppers, may provide excellent breathability and stretchability, but has the shortcoming of lacking sturdiness.

[0009] Accordingly, it is necessary to manufacture a shoe upper so as to simultaneously and appropriately configure stretchability, breathability, and sturdiness required for each portion of the shoe upper.(Related Art Documents)

[0020] FIGS. 1 to 4 are schematic diagrams illustrating specific examples of shoe uppers using stretchable yarn as weft yarn according to an embodiment of the present disclosure. FIGS. 5 to 10 are schematic diagrams illustrating specific examples of shoe uppers using both stretchable yarn and normal yarn as weft yarn according to another embodiment of the present disclosure. FIGS. 11 and 12 are schematic diagrams illustrating a shoe upper using warp yarn formed from a warp yarn bundle of two or more strands of yarn according to another embodiment of the present disclosure. [BEST MODE FOR CARRYING OUT THE INVENTION]

[0021] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0022] In this specification, fabrics are largely divided into a general weave and a twisted weave.

[0023] In the present specification, the general weave refers to a fabric made up of a warp yarn and a weft yarn perpendicularly crossing each other, and for example, a three-way weave represented by a plain weave, a twill weave, and a satin weave corresponds thereto.

[0024] In the present specification, the twisted weave refers to a fabric in which the weft yarns are formed side by side, but the warp yarns are twisted by switching positions at regular intervals. For example, a leno weave in which a pair of two warp yarns including a first warp yarn and a second warp yarn is twisted to cross each other in opposite directions around the weft yarn to form an opening and which is woven so that the weft yarn penetrates the opening corresponds to the twisted weave. In the case of the leno weave in the present specification, in the pair of two warp yarns, the first warp yarn passes under the weft yarn, and the second warp yarn passes over the weft yarn, wherein the first warp yarn and the second warp yarn are twisted to cross each other in opposite directions so as to be woven, while the first warp yarn passes over the second warp yarn.

[0025] Generally, warp yarn is inserted into a heald eye positioned at the center of a heald so that the warp yarn may penetrate, then, the warp yarn is raised and lowered by a vertical movement of the heald to form an opening between neighboring strands of warp yarn, the weft yarn is inserted into the opening, and thus, a fabric is woven. According to a type of an opening device, the fabric may be divided into a dobby fabric in which a simple weave or a small pattern may be woven, and a jacquard fabric in which a large or complex pattern may be woven.

[0026] The dobby fabric is woven using a dobby device when a relatively small pattern is to be displayed on the fabric. Depending on the pattern, for example, a plurality of healds are respectively fixed to 20 to 40 heald frame and move up and down together, the heald movement is controlled to form the opening between the warp yarn, the weft yarn is inserted into the formed opening, and thus, the dobby fabric is woven.

[0027] In the jacquard fabric, each strand of warp yarn is controlled by an independent heald, the heald is not fixed to the heald frame, but each heald moves up and down independently, the heald movement is controlled to form an opening between the warp yarn, the weft is inserted into the formed opening, and the fabric is woven. The jacquard fabric is woven by a jacquard loom.

[0028] In the present disclosure, a shoe upper including a general weave and a twisted weave may be continuously woven in a single process by a heterogeneous weave fabric weaving loom including a jacquard heald and a leno heald. In this regard, Korean Patent No. 10-1557130 (Patent Document 2) discloses a loom for weaving a fabric including heterogeneous weaves, shoe uppers woven using the same, and shoes.

[0029] Specifically, referring to the drawing presented in Patent Document 2, the twisted weave is woven when a leno heald 10 operates on a loom for weaving a fabric including heterogeneous weaves, and the general weave which is a non-twisted weave may be woven when the leno heald 10 does not operate and only the jacquard heald 20 operates. Herein, not only the jacquard heald 20 but also the leno heald 10 are not fixed to the heald frame and may move up and down independently, so that the heald movement may be controlled.

[0030] As such, a fabric woven in one process by a loom for weaving a fabric including heterogeneous weaves including a jacquard heald and a leno heald is called a leno-jacquard fabric in an embodiment of the present disclosure. Accordingly, the leno-jacquard fabric according to an embodiment of the present disclosure may be configured of a heterogeneous weave of a general weave and a leno weave, or may be configured only of a general weave, or may be configured only of a leno weave.

[0031] The shoe upper according to an embodiment of the present disclosure may be woven as an integral piece as described above, and details regarding such an integrally woven shoe upper are disclosed in detail in Korean Patent No. 10-1437472 (Patent Document 1).

[0032] FIGS. 1 to 4 are schematic diagrams illustrating a portion of shoe uppers according to an embodiment of the present disclosure. Specifically, FIGS. 1 to 4 are schematic diagrams illustrating specific examples of shoe uppers using a stretchable yarn as a weft yarn. Hereinafter, various embodiments of the present disclosure will be described with reference to the drawings. For identical components, one drawing will be referred to and descriptions in the remaining drawings will be omitted.

[0033] Referring to FIGS. 1 to 4, the shoe upper 100, 200, 300, 400 may include a first zone 110, 210, 310, 410 and a second zone 120, 220, 320, 420, wherein the stretchability of the first zone 110, 210, 310, 410 is greater than the stretchability of the second zone 120, 220, 320, 420. The stretchability refers to the degree to which the shoe upper stretches.

[0034] The shoe upper 100, 200, 300, 400 is woven by binding a warp yarn 130, 230, 330, 430 and a weft yarn 140, 240, 340, 440.

[0035] The weft yarn 140, 240, 340, 440 may include a stretchable yarn. The stretchable yarn is stretchable. For example, polyurethane stretchable yarn may be used, but is not limited thereto.

[0036] The warp yarn 130, 230, 330, 430 includes a first warp yarn 131, 231, 331, 431 and a second warp yarn 132, 232, 332, 432, wherein the first warp yarn 131, 231, 331, 431 and the second warp yarn 132, 232, 332, 432 may form a warp yarn pair and be twisted to cross each other in opposite directions around the weft yarn 140, 240, 340, 440 to form an opening H.

[0037] Accordingly, the first zone 110, 210, 310, 410 and the second zone 120, 220, 320, 420 may be woven with a leno weave in which the weft yarn 140, 240, 340, 440 is woven while penetrating the opening H.

[0038] In an embodiment of the present disclosure, the shoe upper 100, 200, 300, 400 may be configured such that the number of openings H through which the weft yarn 140, 240, 340, 440 penetrates is greater in the second zone 120, 220, 320, 420 than in the first zone 110, 210, 310, 410.

[0039] Referring to FIGS. 1, 2 and 4, the number of openings H through which the weft yarn 140, 240, 440 penetrates is one in the first zone 110, 210, 410 and two in the second zone 120, 220, 420. Referring to FIG. 3, the number of openings H through which the welt yarn 340 penetrates is two in the first zone 310 and four in the second zone 320.

[0040] Herein, the number of openings H through which the weft yarn 140, 240, 340, 440 penetrates is based on the repeating unit of the same area of the shoe upper. Accordingly, in FIG. 3, the number of openings H through which the weft yarn 340 penetrates needs to be calculated by considering that there are further included two warp yarn pairs to the right of the drawing in the second zone 320.

[0041] When the shoe upper is made of a leno weave woven with weft yarn which is a stretchable yarn, the warp yarn pair may tightly bind the weft yarn to minimize the length of the weft yarn between the openings where the weft yarn is bound, thereby forming a low-stretchability zone with reduced stretchability.

[0042] In contrast, when the warp yarn pair binds the weft yarn by skipping another warp yarn pair adjacent thereto, the warp yarn pair binds the weft yarn loosely, so the length of the weft yarn between the openings where the weft yarn is bound increases. Accordingly, the unique stretchability of the stretchable yarn may be effectively utilized to form a high-stretchability zone.

[0043] FIG. 1 is a schematic diagram illustrating a shoe upper using a one-strand weft yarn according to another embodiment of the present disclosure.

[0044] Referring to FIG. 1, the warp yarn 130 may include a first warp yarn pair 130a', 130b' and a second warp yarn pair 130a", 130b" that are disposed alternately adjacent to each other.

[0045] Referring to FIGS. 1A and 1B, a shoe upper 100a according to one specific embodiment may be configured such that the directions in which the first warp yarn pair 130a' and the second warp yarn pair 130a" are each twisted to form the opening H may be the same. Specifically, a 1a warp yarn 131a', 131a" and a 2a warp yarn 132a', 132a" of the first warp yarn pair 130a' and the second warp yarn pair 130a" are twisted to cross each other in opposite directions so that the 1a warp yarn 131a', 131a" passes over the 2a warp yarn 132a', 132a" to form the opening.

[0046] Referring to FIGS. 1C and 1D, a shoe upper 100b according to yet another specific embodiment may be configured such that the directions in which the first warp yarn pair 130b' and the second warp yarn pair 130b" are each twisted to form the opening H may be opposite to each other. Specifically, a 1b' warp yarn 131b' and a 2b' warp yarn 132b' of the first warp yarn pair 130b' are twisted to cross each other in opposite directions so that the 1b' warp yarn 131b' passes under the 2b' warp yarn 132b' to form the opening, whereas a 1b" warp yarn 131b" and a 2b" warp yarn 132b" of the second warp yarn pair 130b" are twisted to cross each other in opposite directions so that the 1b" warp yarn 131b" passes over the 2b" warp yarn 132b" to form the opening.

[0047] Referring to FIG. 1, in yet another specific embodiment, in the first zone 110, the weft yarn 140 may alternately penetrate the openings H formed by the warp yarn pair 130 one by one in a weft yarn direction x or a warp yarn direction y.

[0048] Specifically, the weft yarn 140 may include a first weft yarn 141a, 141b and a second weft yarn 142a, 142b that are disposed alternately adjacent to each other. In addition, the opening H may include an opening Ha formed by the first warp yarn pair 130a', 130b' and an opening Hb formed by the second warp yarn pair 130a", 130b".

[0049] Referring to FIGS. 1A and 1C, in the first zone 110a, 110b, the first weft yarn 141a, 141b and the second weft yarn 142a, 142b alternately penetrate each of the opening Ha and the opening Hb one by one in the weft direction x. In the warp yarn direction y, the first weft yarn 141a, 141b sequentially penetrates only the opening Hb, and the second weft yarn 142a, 142b sequentially penetrates only the opening Ha.

[0050] Referring to FIGS. 1B and 1D, in the first zone 110a, 110b, the first weft yarn 141a, 141b and the second weft yarn 142a, 142b alternately penetrate each of the opening Ha and the opening Hb one by one in the weft yarn direction x and the warp yarn direction y.

[0051] FIGS. 2 to 4 are schematic diagrams illustrating a shoe upper using weft yarn formed from a weft yarn bundle of two or more strands of yarn according to yet another embodiment of the present disclosure.

[0052] Referring to FIGS. 2 to 4, the weft yarn 240, 340, 440 may form a weft yarn group 240, 340, 440 including a first weft yarn 241, 341, 441 disposed on a rear surface and a second weft yarn 242, 342, 442 disposed on a front surface. Herein, the first weft yarn 241, 341, 441 and the second weft yarn 242, 342, 442 may be disposed to overlap each other on a plane.

[0053] Although not shown in the drawing, the first weft yarn and the second weft yarn may be disposed adjacent to each other on the plane.

[0054] In the first zone 210, 310, 410, the first weft yarn 241, 341, 441 and the second weft yarn 242, 342, 442 may each penetrate different openings Ha', Ha" among the openings formed by the warp yarn 230, 330, 430. In the second zone 220, 320, 420, the first weft yarn 241, 341, 441 and the second weft yarn 242, 342, 442 may simultaneously penetrate one opening Hb formed by the warp yarn 230, 330, 430. Due to this configuration, the first zone 210, 310, 410 with high stretchability may form a high-stretchability zone in which the warp yarn and the weft yarn are loosely bound and the stretchability inherent in the stretchable yarn is secured. In contrast, the second zone 220, 320, 420 with low stretchability may form a low-stretchability zone in which the warp yarn and the weft yarn are tightly bound and the stretchability of the stretchable yarn is reduced.

[0055] In yet another specific embodiment, referring to FIG. 2, the warp yarn 230 may include a first warp yarn pair 230a', 230b' and a second warp yarn pair 230a", 230b" that are disposed alternately adjacent to each other.

[0056] Herein, the directions in which the first warp yarn pair 230a', 230b' and the second warp yarn pair 230a", 230b" are each twisted to form the opening H may be the same.

[0057] Referring to FIG. 2A, in a 1a zone 210a, 1a weft yarn 241a and 2a weft yarn 242a may each alternately penetrate the opening Ha formed by the warp yarn pair 230a in the weft yarn direction x one by one and may sequentially penetrate the opening in the warp yarn direction y. Specifically, the 1a weft yarn 241a may penetrate only the opening Ha" formed by the 2a warp yarn pair 230a", and the 2a weft yarn 242a may penetrate only the opening Ha' formed by the 1a warp yarn pair 230a'.

[0058] Referring to FIG. 2B, in a 1b zone 210b, 1b weft yarn 241b and 2b weft yarn 242b may each alternately penetrate the opening Ha formed by the warp yarn pair 230b one by one in the warp yarn direction y and the weft yarn direction x. Specifically, in the 1b zone 210b, the 2b weft yarn 242b and the 1b weft yarn 241b may alternately penetrate the opening Ha' formed by the 1b warp yarn pair 230b' in the warp yarn direction y, and the 1b weft yarn 241b and the 2b weft yarn 242b may alternately penetrate the opening Ha" formed by the 2b warp yarn pair 230b" in the warp yarn direction y.

[0059] Accordingly, shoe uppers with various patterns may be manufactured by selectively controlling the weft yarn penetrating the opening H.

[0060] In yet another specific embodiment, referring to FIGS. 3 and 4, the warp yarn 330, 430 may include a first warp yarn pair 330', 430' and a second warp yarn pair 330", 430" that are disposed alternately adjacent to each other.

[0061] Herein, the directions in which the first warp yarn pair 330', 430' and the second warp yarn pair 330", 430" are each twisted to form the opening H may be opposite to each other.

[0062] As illustrated in FIGS. 2 to 4, shoe uppers with various patterns may be manufactured by changing the direction in which the warp yarn pairs are twisted to form the opening H.

[0063] In yet another specific embodiment, referring to FIG. 3, the weft yarn group 340 may include a first weft yarn group 340' including a 1' weft yarn 341' and a 2' weft yarn 342'. In this connection, in the first zone 310, the 1' weft yarn 341' and the 2' weft yarn 342' may each individually and sequentially penetrate two openings Ha', Ha" adjacent to each other in the weft yarn direction x, then skip two openings, and then sequentially penetrate two openings again.

[0064] To be more specific, in the first zone 310, the first warp yarn pair 330' may include a 1a warp yarn pair 330'a and a 1b warp yarn pair 330'b, and the second warp yarn pair 330" may include a 2a warp yarn pair 330"a and a 2b warp yarn pair 330"b. Accordingly, the 1a warp yarn pair 330'a, the second warp yarn pair 330"a, the 1b warp yarn pair 330'b, and the 2b warp yarn pair 330"b may be disposed adjacent to each other in that order. Herein, the 1' weft yarn 341' may penetrate the opening Ha' formed by each of the 1a warp yarn pair 330'a and the 2a warp yarn pair 330"a, and the 2' weft yarn 342' may not penetrate therethrough. The 1' weft yarn 341' may not penetrate the opening Ha" formed by each of the 1b warp yarn pair 330'b and the 2b' warp yarn pair 330"b, and the 2' weft yarn 342' may penetrate therethrough.

[0065] Due to this configuration, the stretchability of the first zone 310 may be adjusted in various ways.

[0066] In yet another specific embodiment, the weft yarn group 340 may further include a second weft yarn group 340" including a 1" weft yarn 341" and a 2" weft yarn 342". Accordingly, the first weft yarn group 340' and the second weft yarn group 340" may be disposed alternately adjacent to each other. In this connection, in the first zone 310, the 1" weft yarn 341" may penetrate only one opening among two other openings Hb' adjacent in a warp yarn direction y to the two openings Ha' through which the 1' weft yarn 341' sequentially penetrates.

[0067] To be more specific, in the first zone 310, the 1" weft yarn 341" may not penetrate each opening Hb'1, Hb"2 formed by the 1a warp yarn pair 330'a and the 2b warp yarn pair 330"b, and the 2" weft yarn 342" may penetrate therethrough. The 1" weft yarn 341" may penetrate each opening Hb'2, Hb"1 formed by the 2a warp yarn pair 330"a and the 1b warp yarn pair 330'b, and the 2" weft yarn 342" may not penetrate therethrough.

[0068] Accordingly, upon reviewing the degree to which one of strands of the weft yarn forming the weft yarn group in the first zone 310 of the shoe upper shown in FIG. 3 is bound by a warp yarn pair, it was identified that the weft yarn is bound by skipping two warp yarn pairs. Specifically, upon reviewing a repeating unit U of the weaves in FIG. 3, the 2" weft yarn 342" is sequentially bound to the opening formed by the 1a warp yarn pair 330'a, and then skips over the openings formed by the 2a" warp yarn pair 330"a and the 1b warp yarn pair 330'b without being bound and is bound to the opening formed by the subsequent 2b warp yarn pair 330"b.

[0069] Upon reviewing the degree to which one strand of the weft yarn forming the weft yarn group is bound by the warp yarn pair in the first zone 210, 410 of the shoe upper shown in the aforementioned FIG. 2 and FIG. 4 described below, it was found that the weft yarn is bound by skipping one warp yarn pair.

[0070] Accordingly, in comparison of the shoe uppers of FIG. 3 with those of FIGS. 2 and 4, it may be understood that the first zone of the shoe upper of FIG. 3 is configured to have a relatively looser binding than the first zone of the shoe uppers of FIGS. 2 and 4, and thus has greater stretchability.

[0071] As such, when the weft yarn that makes up a leno weave is used as a stretchable yarn, shoe uppers that include various zones with different stretchability may be manufactured by varying the degree of binding between the warp yarn and the weft yarn.

[0072] In yet another specific embodiment, referring to FIG. 4, similarly to FIG. 2B described above, in the first zone 410, the second weft yarn 442 and the first weft yarn 441 may penetrate the opening Ha' formed by the first warp yarn pair 430a' alternately in the warp yarn direction y, and the first weft yarn 441 and the second weft yarn 442 may penetrate the opening Ha" formed by the second warp yarn pair 430" alternately in the warp yarn direction y.

[0073] Although not illustrated, similarly to FIG. 2A, in the first zone 410, the first weft yarn 441 may penetrate only the opening Ha" formed by the second warp yarn pair 430", and the second weft yarn 442 may penetrate only the opening Ha' formed by the first warp yarn pair 430'.

[0074] FIGS. 5 to 10 are schematic diagrams illustrating showing a portion of a shoe upper according to an embodiment of the present disclosure. Specifically, FIGS. 5 to 10 are schematic diagrams illustrating specific examples of shoe uppers that use both stretchable yarn and normal yarn as weft yarn. Hereinafter, various embodiments of the present disclosure will be described with reference to the drawings. For identical components, one drawing will be referred to and descriptions in the remaining drawings will be omitted.

[0075] Referring to FIGS. 5 to 10, a shoe upper 500, 600, 700, 800, 900, 1000 may include a first zone 510, 610, 710, 810, 910, 1010 and a second zone 520, 620, 720, 820, 920, 1020, and the stretchability of the first zone 510, 610, 710, 810, 910, 1010 is greater than the stretchability of the second zone 520, 620, 720, 820, 920, 1020. The stretchability refers to the degree to which the shoe upper stretches.

[0076] The shoe upper 500, 600, 700, 800, 900, 1000 is woven by binding a warp yarn 530, 630, 730, 830, 930, 1030 and a weft yarn 540, 640, 740, 840, 940, 1040.

[0077] The weft yarn 540, 640, 740, 840, 940, 1040 may include a first weft yarn 541, 641, 741, 841, 941, 1041 which is a stretchable yarn and a second weft yarn 542, 642, 742, 842, 942, 1042 which is a normal yarn. The stretchable yarn is stretchable. For example, polyurethane stretchable yarn may be used, but is not limited thereto. The normal yarn may be, for example, ordinary polyester false twist yarn or polyester regenerate yarn, but are not limited thereto.

[0078] In comparison of the shoe uppers shown in FIGS. 5 to 10 with the shoe uppers shown in FIGS. 1 to 4, a common feature resides in that the number of openings through which the weft yarn penetrates in zones with different stretchability is different, and a different feature resides in that the shoe uppers of FIGS. 1 to 4 use a stretchable yarn as the weft yarn, whereas the shoe uppers of FIGS. 5 to 10 use both the stretchable yarn and the general yarn as the weft yarn.

[0079] The warp yarn 530, 630, 730, 830, 930, 1030 includes a first warp yarn 531, 631, 731, 831, 931, 1031 and a second warp yarn 532, 632, 732, 832, 932, 1032, wherein the first warp yarn 531, 631, 731, 831, 931, 1031 and the second warp yarn 532, 632, 732, 832, 932, 1032 may form a warp yarn pair and be twisted to cross each other in opposite directions around the weft yarn 540, 640, 740, 840, 940, 1040 to form an opening H.

[0080] Accordingly, the first zone 510, 610, 710, 810, 910, 1010 and the second zone 520, 620, 720, 820, 920, 1020 may be woven with a leno weave in which the weft yarn 540, 640, 740, 840, 940, 1040 is woven while penetrating the opening H.

[0081] In an embodiment of the present disclosure, the shoe upper 500, 600, 700, 800, 900, 1000 may be configured such that the number of openings H through which the second weft yarn 542, 642, 742, 842, 942, 1042, which is a normal yarn, penetrates is greater in the second zone 520, 620, 720, 820, 920, 1020 than in the first zone 510, 610, 710, 810, 910, 1010.

[0082] The number of openings H through which the first weft yarn 541, 641, 741, 841, 941, 1041, which is a stretchable yarn, penetrates may be the same in the first zone 510, 610, 710, 810, 910, 1010 and the second zone 520, 620, 720, 820, 920, 1020, or may be configured to be greater in the second zone 520, 620, 720, 820, 920, 1020.

[0083] Referring to FIGS. 5 to 10 (excluding FIGS. 9C and 10C), similarly to what was described above with respect to FIGS. 1, 2, and 4, the number of openings H through which the second weft yarn 542, 642, 742, 842, 942, 1042, which is a normal yarn, penetrates is one in the first zone 510, 610, 710, 810, 910, 1010, and two in the second zone 520, 620, 720, 820, 920, 1020. Referring to FIGS. 9C and 10C, the number of openings H through which the second weft yarn 942c, 1042c, which is a general yarn, penetrates is two in a first zone 910c, 1010c, and four in a second zone 920c, 1020c.

[0084] Herein, the number of openings H through which the second warp yarn 542, 642, 742, 842, 942, 1042 penetrates is based on the repeating unit of the same area of the shoe upper. Accordingly, in the case of FIGS. 9C and 10C, the number of openings H through which the second warp yarn 942c, 1042c penetrates needs to be calculated by considering that there are two more warp yarn pairs to the right of the drawing in the second zone 920c, 1020c.

[0085] When the shoe upper is made of a leno weave woven using both stretchable weft yarn and unstretchable normal weft yarn, the warp yarn pair tightly binds the normal weft yarn to minimize the length of the normal weft yarn between the openings where the normal weft yarn is bound. As a result, the stretchability of the stretchable weft yarn participating in the weaving together with the normal weft yarn is reduced, so that a low-stretchability zone may be formed.

[0086] In contrast, when the warp yarn pair binds the normal weft yarn by skipping another warp yarn pair adjacent thereto, the warp yarn pair binds the normal weft yarn loosely, so the length of the normal weft yarn between the openings where the normal weft yarn is bound increases. Accordingly, the unique stretchability of the stretchable yarn participating in the weaving together with the normal weft yarn may be effectively utilized to form a high-stretchability zone.

[0087] FIGS. 5 and 6 are schematic diagrams illustrating the shoe upper 500, 600 using one-strand weft yarn according to another embodiment of the present disclosure. In other words, the weft yarn 540, 640 includes the first weft yarn 541, 641 which is a stretchable yarn and the second weft yarn 542, 642 which is a normal yarn, but each of weft yarns may be made of one strand.

[0088] The first weft yarn 541, 641 and the second weft yarn 542, 642 may be disposed alternately adjacent to each other.

[0089] In another specific embodiment, referring to FIG. 5, the number of openings H through which first weft yarn 541a, 541b penetrates may be the same in a first zone 510a, 510b and a second zone 520a, 520b as described above. In this configuration, the binding degree of the first weft yarn 541a, 541b, which is a stretchable yarn, in the first zone 510a, 510b and the second zone 520a, 520b is the same, whereas the binding degree of second weft yarn 542a, 542b, which is a normal yarn, is different. Accordingly, there is no change in the stretchability of the shoe upper due to the binding degree of the first weft yarn 541a, 541b, which is a stretchable yarn, and only a change in the stretchability of the shoe upper due to the binding degree of the second weft yarn 542a, 542b, which is a normal yarn, occurs.

[0090] In yet another specific embodiment, referring to FIG. 6, as described above, the number of openings H through which first weft yarn 641a, 641b penetrates may be greater in a second zone 620a, 620b than in a first zone 610a, 610b. In this configuration, the binding degrees of the first weft yarn 641a, 641b, which is a stretchable yarn, and the second weft yarn 642a, 642b, which is a normal yarn, are all different in the first zone 610a, 610b and the second zone 620a, 620b. Accordingly, the binding degree of the shoe upper changes due to both the binding degree of the first weft yarn 641a, 641b, which is a stretchable yarn, and the binding degree of the second weft yarn 642a, 642b, which is a normal yarn.

[0091] Accordingly, in comparison of the first zones 510, 610 shown in FIGS. 5 and 6, the binding degree of the second weft yarn, which is a normal yarn, is the same, but the binding degree of the first weft yarn, which is a stretchable yarn, is greater because of tight binding in the shoe upper of FIG. 5, and smaller because of loose binding in the shoe upper of FIG. 6. Accordingly, with respect to the stretchability of the first zone 510, 610, the stretchability of the first zone 610 of FIG. 6 is greater than the stretchability of the first zone 510 of FIG. 5.

[0092] In yet another specific embodiment, referring to FIGS. 5A and 6B, in the first zone 510a, 610a, the second waft yarn 542a, 642a may penetrate the opening Ha' formed by a first warp yarn pair 530a', 630a' and may not penetrate the opening Ha" formed by a second warp yarn pair 530a", 630a".

[0093] Referring to FIGS. 5B and 6B, in the first zone 510b, 610b, the second weft yarn 542b, 642b may alternately penetrate the opening Ha' formed by a warp yarn pair 530b, 630b in the warp yarn direction y and the weft yarn direction x one by one.

[0094] Although not shown in the drawing, the directions in which the first warp yarn pair 530', 630' and the second warp yarn pair 530", 630" in the shoe uppers shown in FIGS. 5 and 6 are each twisted to form the openings Ha', Ha" may be the same or opposite to each other.

[0095] FIGS. 7 to 10 are schematic diagrams illustrating a shoe upper using weft yarn formed from a weft yarn bundle of two or more strands of yarn according to yet another embodiment of the present disclosure.

[0096] Referring to FIGS. 7 to 10, the weft yarn may form a weft yarn group 540, 640, 740, 840, 940, 1040 in which the first weft yarn 541, 641, 741, 841, 941, 1041, which is a stretchable yarn, is disposed on a rear surface and the second weft yarn 542, 642, 742, 842, 942, 1042, which is a normal yarn, is disposed on the front surface so as to overlap each other on a plane.

[0097] In yet another specific embodiment, referring to FIGS. 7 and 9, the number of openings H through which the first weft yarn 741, 941, which is a stretchable yarn as described above, penetrates may be the same in the first zone 710, 910 and the second zone 720, 920. In this configuration, the binding degree of the first weft yarn 741, 941, which is a stretchable yarn, in the first zone 710, 910 and the second zone 720, 920 is the same, while the binding degree of the second weft yarn 742, 942, which is a normal yarn, is different. Accordingly, there is no change in the stretchability of the shoe upper due to the binding degree of the first weft yarn 741, 941, which is a stretchable yarn, and only a change in the stretchability of the shoe upper due to the binding degree of the second weft yarn 742, 942, which is a normal yarn, occurs.

[0098] In yet another specific embodiment, referring to FIGS. 7 and 9, the warp yarn 730, 930 may include a first warp yarn pair 730a', 730b', 930a', 930b', 930c' and a second warp yarn pair 730a", 730b", 930a", 930b", 930c" that are alternately disposed adjacent to each other.

[0099] Referring to FIG. 7 herein, the directions in which the first warp yarn pair 730a', 730b' and the second warp yarn pair 730a", 730b" are each twisted to form the opening Ha', Ha" may be the same.

[0100] Referring to FIG. 9, the directions in which the first warp yarn pair 930a', 930b', 930c' and the second warp yarn pair 930a", 930b", 930c" are each twisted to form the opening H may be opposite to each other.

[0101] In yet another specific embodiment, referring to FIG. 9C, a weft yarn group 940c may include a 1c weft yarn group 940c' including a 1c' weft yarn 941c' and a 2c' weft yarn 942c'. In this connection, in a 1c zone 910c, the 2c' weft yarn 942c' may sequentially penetrate two adjacent openings Ha" in the weft yarn direction x, then skip two openings Ha', and then sequentially penetrate two openings again. As described above, the number of openings H through which the 1c' weft yarn 941c' penetrates is the same in the 1c zone 910c and the 2c zone 920c.

[0102] To be more specific, the first warp yarn pair 930c' may include a 1a warp yarn pair 930c'1 and a 1b warp yarn pair 930c'2, and the second warp yarn pair 930c" may include a 2a warp yarn pair 930c"1 and a 2b warp yarn pair 930c"2. Accordingly, the 1a warp yarn pair 930c'1, the 2a warp yarn pair 930c"1, the 1b warp yarn pair 930c'2, and the 2b warp yarn pair 930c"2 may be disposed adjacent to each other in that order. In this connection, the 1c' weft yarn 941c' may penetrate all the openings Ha', Ha" formed by the warp yarn pairs. The 2c' weft yarn 942c' does not penetrate each opening Ha' formed by the 1a warp yarn pair 930c'1 and the 2a warp yarn pair 930c"1, and may penetrate each opening Ha" formed by the 1b warp yarn pair 930c'2 and the 2b warp yarn pair 930c"2.

[0103] In yet another specific embodiment, referring to FIG. 9C, the weft yarn group 940c further includes a 2c weft yarn group 940c" including a 1c" weft yarn 941c" and a 2c" weft yarn 942c", and the 1c weft yarn group 940c' and the 2c weft yarn group 940c" may be disposed alternately adjacent to each other. In this connection, in the 1c zone 910c, the 2c" weft yarn 942c" may penetrate only one opening among two other openings Hb" adjacent in a warp yarn direction y to the two openings Ha" through which the 2c' weft yarn 942c' penetrates sequentially.

[0104] To be more specific, in the 1c zone 910c, the 1c" weft yarn 941c" may penetrate all the openings Hb', Hb" formed by the warp yarn pairs. The 2c" waft yarn 942c" does not penetrate each opening formed by the 2a warp yarn pair 930c"1 and the 1b warp yarn pair 930c'2, and may penetrate each opening formed by the 1a warp yarn pair 930c'1 and the 2b warp yarn pair 930c"2.

[0105] Accordingly, upon reviewing the degree to which the 2c weft yarn 942c', 942c", which is a normal yarn among the weft yarn forming the weft yarn group 940c, in the first zone 910c of the shoe upper shown in FIG. 9C is bound by the warp yarn pair, it was identified that the 2c weft yarn 942c', 942c", which is a normal yarn, is bound by skipping two warp yarn pairs. Specifically, upon reviewing the repeating unit U of the weaves in FIG. 9C, the 2c" weft yarn 942c" is sequentially bound to the opening formed by the 1a warp yarn pair 930c'1, and then skips over the openings formed by the 2a warp yarn pair 930c"1 and the 1b warp yarn pair 930c'2 without being bound and is bound to the opening formed by the subsequent 2b warp yarn pair 930c"2.

[0106] In the first zone 710, 810, 910a, 910b, 1010 of the shoe upper shown in the aforementioned FIGS. 7, 8, 9A, 9B, and 10 (excluding FIG. 10C), upon reviewing the degree to which the second weft yarn, which is a normal yarn among the weft yarn forming the weft yarn group, is bound by the warp yarn pair, it may be identified that the second weft yarn, which is a normal yarn, is bound by skipping one warp yarn pair.

[0107] Accordingly, in comparison of the shoe upper of FIG. 9C with those of FIGS. 7, 8, 9A, 9B, and 10, it may be understood that the first zone of the shoe upper of FIG. 9C is configured to have relatively looser binding than the first zone of the shoe uppers of FIGS. 7, 8, 9A, 9B, and 10, and thus has greater stretchability.

[0108] As such, when the weft yarn that makes up a leno weave is used as a weft yarn bundle configured of a stretchable yarn and a normal yarn, a shoe upper that includes various areas with different stretchability may be manufactured by varying the degree of binding between the warp yarn and the normal yarn.

[0109] In yet another specific embodiment, referring to FIGS. 8 and 10, the number of openings H through which the first weft yarn 841, 1041 penetrates may be greater in the second zone 820, 1020 than in the first zone 810, 1010. In this configuration, the binding degree of the first weft yarn 841, 1041, which is a stretchable yarn, and the second weft yarn 842, 1042, which is a normal yarn, are all different in the first zone 810, 1010 and the second zone 820, 1020. Accordingly, the binding degree of the shoe upper changes due to both the binding degree of the first weft yarn 841, 1041, which is a stretchable yarn, and the binding degree of the second weft yarn 842, 1042, which is a normal yarn.

[0110] In yet another specific embodiment, referring to FIGS. 8 and 10, the warp yarn 830, 1030 may include a first warp yarn pair 830a', 830b', 1030a', 1030b', 1030c' and a second warp yarn pair 830a", 830b", 1030a", 1030b", 1030c" that are alternately disposed adjacent to each other.

[0111] Referring to FIG. 8 herein, the directions in which the first warp yarn pair 830a', 830b' and the second warp yarn pair 830a", 830b" are each twisted to form the opening H may be the same.

[0112] Referring to FIG. 10, the directions in which the first warp yarn pair 1030a', 1030b', 1030c' and the second warp yarn pair 1030a", 1030b", 1030c" are each twisted to form the opening H may be opposite to each other.

[0113] In yet another specific embodiment, referring to FIG. 10C, the weft yarn group 1040c may include a first weft yarn group 1040c' including a 1c" weft yarn 1041c' and a 2c' weft yarn 1042c'. In this connection, in the 1c zone 1010c, the 1c' weft yarn 1041c' and the 2c' weft yarn 1042c' may each individually and sequentially penetrate two openings Ha', Ha" adjacent to each other in the weft yarn direction x, then skip two openings, and then sequentially penetrate two openings again.

[0114] To be more specific, in the 1c zone 1010c, the first warp yarn pair 1030c' may include a 1a warp yarn pair 1030c'1 and a 1b warp yarn pair 1030c'2, and the second warp yarn pair 1030c" may include a 2a warp yarn pair 1030c"1 and a 2b warp yarn pair 1030c"2. Accordingly, the 1a warp yarn pair 1030c'1, the 2a warp yarn pair 1030c"1, the 1b warp yarn pair 1030c'2, and the 2b warp yarn pair 1030c"2 may be disposed adjacent to each other in that order. In this connection, the 1c' weft yarn 1041c' may penetrate the opening Ha' each formed by the 1a warp yarn pair 1030c'1 and the 2a warp yarn pair 1030c"1, and the 2c' weft yarn 1042c' may not penetrate therethrough. The 1c' weft yarn 1041c' may not penetrate the opening Ha" each formed by the 1b warp yarn pair 1030c'2 and the 2b warp yarn pair 1030c"2, and the 2c' weft yarn 1042c' may penetrate therethrough.

[0115] Due to this configuration, the stretchability of the 1c zone 1010c may be adjusted in various ways.

[0116] In yet another specific embodiment, the weft yarn group 1040c may further include a 2c weft yarn group 1040c" including a 1c" weft yarn 1041c" and a 2c" weft yarn 1042c". Accordingly, the 1c weft yarn group 1040c' and the 2c weft yarn group 1040c" may be disposed alternately adjacent to each other. In this connection, in the 1c zone 1010c, the 1c" weft yarn 1041c" may penetrate only one opening among two other openings Hb' adjacent in the warp yarn direction y to the two openings Ha' through which the 1c' weft yarn 1041c' sequentially penetrates.

[0117] To be more specific, in the 1c zone 1010c, the 1c" weft yarn 1041c" may not penetrate each opening Hb'1, Hb"2 formed by the 1a warp yarn pair 1030c'1 and the 2b warp yarn pair 1030c"2, and the 2c" weft yarn 1042c" may penetrate therethrough. The 1c" weft yarn 1041c" may penetrate each opening Hb'2, Hb"1 formed by the 2a warp yarn pair 1030c"1 and the 1b warp yarn pair 1030c'2, and the 2c" weft yarn 1042c" may not penetrate therethrough.

[0118] Accordingly, upon reviewing the degree to which both the stretchable yarn and the normal yarn forming the weft yarn group 1010c in the 1c zone 1010c of the shoe upper shown in FIG. 10C are bound by warp yarn pairs, it may be identified that both the stretchable yarn and the normal yarn are bound by skipping two warp yarn pairs.

[0119] In the first zone 910c of the shoe upper presented in the aforementioned FIG. 9C, it may be identified that the second weft yarn, which is a normal yarn, is bound by skipping two warp yarn pairs, which is the same as the shoe upper shown in FIG. 10C. However, the first weft yarn, which is a stretchable yarn, is bound by all weft yarn pairs in FIG. 9C, and is bound by skipping two warp yarn pairs in FIG. 10C. Accordingly, the first zone of the shoe upper of FIG. 10C has greater stretchability than the first zone of the shoe upper of FIG. 9C.

[0120] Referring again to FIGS. 7, 9A, and 9B, the shoe uppers shown in FIGS. 7A and 9A may have both the first weft yarn and the second weft yarn bound by the first warp yarn pair, and may have only the first weft yarn bound by the second warp yarn pair. The shoe uppers shown in FIGS. 7B and 9B may have the positions of the openings where both the first weft yarn and the second weft yarn are bound by the warp yarn pair disposed diagonally on a plane.

[0121] Referring again to FIGS. 8, 10A, and 10B, the shoe uppers shown in FIGS. 8A and 10A may have only the second weft yarn bound by the first warp yarn pair and only the first warp yarn bound by the second warp yarn pair.

[0122] The shoe uppers shown in FIGS. 8B and 10B may have the positions of the openings where one of the weft yarns is bound by the warp yarn pair disposed diagonally on a plane. Specifically, the positions of the opening Ha' where the second weft yarn 942b, 1042b is bound by the first warp yarn pair 830b', 1030b' and the opening Ha"' where the second weft yarn 942b, 1042b is bound by the second warp yarn pair 830b", 1030b" may be disposed diagonally on a plane. The same applies to the first weft yarn 941b, 1041b.

[0123] FIGS. 11 and 12 are schematic diagrams illustrating a shoe upper using warp yarn formed from a warp yarn bundle of two or more strands of yarn according to another embodiment of the present disclosure. In addition, FIG. 11 is a schematic diagram illustrating a shoe upper using a stretchable yarn as weft yarn, and FIG. 12 is a schematic diagram illustrating a specific example of a shoe upper using both a stretchable yarn and a normal yarn as weft yarn.

[0124] Referring to FIG. 11, a shoe upper 1100 may include a first zone 1110 and a second zone 1120, wherein the stretchability of the first zone 1110 is greater than the stretchability of the second zone 1120. The stretchability refers to the degree to which the shoe upper stretches.

[0125] The shoe upper 1100 is woven by binding the warp yarn 1130 and the weft yarn 1140.

[0126] The weft yarn 1140 may include a stretchable yarn. The stretchable yarn is stretchable. For example, polyurethane stretchable yarn may be used, but is not limited thereto.

[0127] The warp yarn 1130 includes a first warp yarn 1131 and a second warp yarn 1132, wherein the first warp yarn 1131 and the second warp yarn 1132 may form a warp yarn pair and be twisted to cross each other in opposite directions around the weft yarn 1140 to form an opening H.

[0128] Accordingly, the first zone 1110 and the second zone 1120 may be woven with a leno weave in which the weft yarn 1140 is woven while penetrating the opening H.

[0129] In an embodiment of the present disclosure, the first warp yarn 1131 and the second warp yarn 1132 forming one warp yarn pair may each be formed as a warp yarn bundle including two or more strands of yarn. FIG. 11A schematically illustrates an enlarged view of the first warp yarn 1131 on the right. As illustrated in FIG. 11A, for example, the first warp yarn 1131 may form a warp yarn bundle including four strands of yarn (h, i, j, k).

[0130] In addition, the warp yarn 1130 may include a first warp yarn pair 1130a', 1130b', 1130c' disposed in the first zone 1110 and a second warp yarn pair 1130a", 1130b", 1130c" disposed in the second zone 1120.

[0131] Herein, in the first zone 1110, all strands of the 1' warp yarn 1131a', 1131b', 1131c' of the first warp yarn pair 1130a', 1130b', 1130c' may pass over the weft yarn 1140, and all strands of the 2' warp yarn 1132a', 1132b', 1132c' may pass under the weft yarn 1140.

[0132] In the second zone 1120, at a position P where the warp yarn 1130 and the weft yarn 1140 cross each other, each strand of yarn (h, i, j, k) of 1" warp yarn 1131a", 1131b", 1131c" of the second warp yarn pair 1130a", 1130b", 1130c" may cross the weft yarn 1140 to form a general weave.

[0133] In yet another specific embodiment, referring to FIG. 11B, at a position P where the warp yarn 1130 and the weft yarn 1140 cross each other in the second zone 1120b, each strand of 2" warp yarn 1132b" of the second warp yarn pair 1130b" may cross the weft yarn 1140 to form a general weave.

[0134] Due to this configuration, the degree to which the weft yarn is bound by the warp yarn pair by the weft yarn penetrating the openings formed by the warp yarn pairs in the leno weave structure using the weft yarn, which is a stretchable yarn, is the same in the first zone 1110 and the second zone 1120. However, unlike the first zone 1110, in the second zone 1120, each strand of the warp yarn formed by the warp yarn bundle forms a general weave at a position where the warp yarn crosses the weft yarn, so the weft yarn may be tightly bound by the warp yarn. Accordingly, the first zone 1110 is relatively loosely bound and the second zone 1120 is relatively tightly bound, and thus the stretchability of the first zone 1110 is greater than the stretchability of the second zone 1120.

[0135] In comparison of the second zone 1120a; 1120b of FIG. 11A and FIG. 11B, it may be identified that the second zone 1120b of FIG. 11B is more tightly bound than the second zone 1120a of FIG. 11A. Accordingly, the second zone 1120A of FIG. 11A has greater stretchability than the second zone 1120B of FIG. 11B.

[0136] In yet another specific embodiment, referring to FIG. 11C, the shoe upper 1100c may further include a third zone 1130. Herein, in the third zone 1130, the warp yarn 1130c', 1130c" extended from the first zone 1110c or the second zone 1120c may cross the weft yarn 1140c" to form a general weave. Accordingly, the stretchability of the second zone 1120c is greater than the stretchability of the third zone 1130.

[0137] In yet another specific embodiment, each strand of the warp yarn 1130c' in the third zone 1130 may cross the weft yarn 1140c" to form a general weave. Accordingly, also in the third zone 1130 forming the general weave, the stretchability of the shoe upper may be controlled by controlling the binding degree of the warp yarn and the weft yarn. In other words, when the entire strands of the warp yarn 1130c" cross the weft yarn 1140c" as a single warp yarn bundle to form a general weave, it is bound relatively loosely, and when each strand of the warp yarn 1130c' individually crosses the weft yarn 1140c" individually to form a general weave, it is bound relatively tightly. Accordingly, even when the third zone 1130 is configured of the general weave, the loosely bound zone has greater stretchability than the tightly bound zone.

[0138] Referring to FIG. 12, a shoe upper 1200 may include a first zone 1210 and a second zone 1220, and the stretchability of the first zone 1210 is greater than the stretchability of the second zone 1220. The stretchability refers to the degree to which the shoe upper stretches.

[0139] The shoe upper 1200 is woven by binding the warp yarn 1230 and the weft yarn 1240.

[0140] The weft yarn may form a weft yarn group 1240 including a first weft yarn 1241, which is a stretchable yarn and is disposed on a rear surface, and a second weft yarn 1242, which is a normal yarn and is disposed on the front surface. Accordingly, the first weft yarn 1241 and the second weft yarn 1242 may be disposed to overlap each other on a plane. The stretchable yarn is stretchable. For example, polyurethane stretchable yarn may be used, but is not limited thereto. The normal yarn may be, for example, ordinary polyester false twist yarn or polyester regenerate yarn, but are not limited thereto.

[0141] The warp yarn 1230 includes a first warp yarn 1231 and a second warp yarn 1232, and the first warp yarn 1231 and the second warp yarn 1232 may form one warp yarn pair and twist while crossing each other in opposite directions around the weft yarn 1240 to form an opening H.

[0142] Accordingly, the first zone 1210 and the second zone 1220 may be woven with a leno weave in which the weft yarn 1240 is woven while penetrating the opening H.

[0143] In an embodiment of the present disclosure, the first warp yarn 1231 and the second warp yarn 1232 forming one warp yarn pair may each be formed as a warp yarn bundle including two or more strands of yarn. FIG. 12A schematically illustrates an enlarged view of the first warp yarn 1231 on the right. As illustrated in FIG. 12A, for example, the first warp yarn 1231 may form a warp yarn bundle including four strands of yarn (h, i, j, k).

[0144] In addition, the warp yarn 1230 may include a first warp yarn pair 1230a', 1230b', 1230c' disposed in the first zone 1210 and a second warp yarn pair 1230a", 1230b", 1230c" disposed in the second zone 1220.

[0145] Herein, in the first zone 1210, all stands of 1' warp yarn 1231a', 1231b', 1231c' of the first warp yarn pair 1230a', 1230b', 1230c' may pass over the second weft yarn 1242, and all strands of 2' warp yarn 1232a', 1232b', 1232c' may pass under the first weft yarn 1241.

[0146] In the second zone 1220, at the position P where the warp yarn 1130 and the weft yarn 1140 cross, each strand of yarn (h, i, j, k) of 1" warp yarn 1231a", 1231b", 1231c" of the second warp yarn pair 1230a", 1230b", 1230c" may cross the second weft yarn 1242 to form a general weave.

[0147] In yet another specific embodiment, referring to FIG. 12B, at the position P where the warp yarn 1230 and the weft yarn 1240 cross in the second zone 1220b, each strand of the 2" warp yarn 1132b" of the second warp yarn pair 1230b" may cross the first weft yarn 1241b to form a general weave.

[0148] Due to this configuration, in a leno weave structure in which the first weft yarn, which is a stretchable yarn, and the second weft yarn, which is a normal yarn, are used together as a weft yarn bundle, the degree to which the weft yarn is bound by the warp yarn pair by the weft yarn penetrating the openings formed by the warp yarn pairs is the same in the first zone 1210 and the second zone 1220. However, unlike the first zone 1210, in the second zone 1220, a general weave is formed at the position where each strand of the warp yarn formed by the warp yarn bundle crosses the second weft yarn, which is a normal yarn, and thus the second weft yarn, which is a normal yarn, may be tightly bound by the warp yarn. Accordingly, upon reviewing the degree of binding of the second weft yarn, which is a normal yarn, the first zone 1210 is relatively loosely bound and the second zone 1220 is relatively tightly bound, and thus the stretchability of the first zone 1210 is greater than the stretchability of the second zone 1220.

[0149] In comparison of the second zone 1220a; 1220b of FIG. 12A and FIG. 12B, it may be identified that the second zone 1220b of FIG. 12B is more tightly bound than the second zone 1220a of FIG. 12A. Accordingly, the second zone 1220a of FIG. 12A has greater stretchability than the second zone 1220b of FIG. 12B.

[0150] In yet another specific embodiment, referring to FIG. 12C, a shoe upper 1200c may further include a third zone 1230. Herein, in the third zone 1230, warp yarn 1230c', 1230c" extended from the first zone 1210c or the second zone 1220c may cross weft yarn 1240c" to form a general weave. Accordingly, the stretchability of the second zone 1220c is greater than the stretchability of the third zone 1230.

[0151] In yet another specific embodiment, the third zone 1230 may include a 3a zone 1230a and a 3b zone 1230b. Herein, a weave point value of the second weft yarn 1242c" forming the third zone 1230 is greater in the 3b zone 1230b than in the 3a zone 1230a. Accordingly, the stretchability of the 3a zone 1230a is greater than the stretchability of the 3b zone 1230b.

[0152] In an embodiment of the present disclosure, the weave point value refers to a value that represents a degree to which warp yarn and weft yarn cross each other and participate in the weave in a fabric weave on a certain plane. For example, in the case of the plain weave among the general weave, since the number of warp yarn (1 up and 1 down) in the repeating unit that constitutes the weave is 2, the weave point value of the plain weave is 1 / 2. In the case of a four-twill weave with a four-piece weave having three up and one down (3 up and 1 down, the weave point value is 1 / 4, and in the case of an eight-twill weave with an eight-piece weave having seven up and one down (7 up and 1 down) structure, the weave point value is 1 / 8. Accordingly, a small number of weave point value means that the weave of the fabric is loosely woven, and a large number of weave point value means that the weave of the fabric is tightly woven.

[0153] Referring to FIG. 12C, for the second weft yarn 1242c", the strands of the warp yarn bundle have two up and six down (2 up and 6 down) in the 3a zone 1230a, so that the wave point value is 2 / 8 = 1 / 4, and have four up and four down (4 up and 4 sown) in the 3b zone 1230b, so that the wave point value is 4 / 8 = 1 / 2. Accordingly, the 3a zone 1230a is more loosely bound than the 3b zone 1230b, so the stretchability is greater.

[0154] Due to this configuration, a shoe upper having both a leno weave and a general weave may be manufactured. By configuring the warp yarn and the weft yarn in each zone as one strand of yarn or two or more strands of yarn and controlling the binding degree of each zone, a shoe upper having a plurality of zones with different stretchability may be manufactured.

[0155] The configuration of the shoe upper using the warp yarn bundle shown in FIGS. 11 and 12 may also be applied to FIGS. 1 to 10.

[0156] Accordingly, in yet another specific embodiment, referring again to FIGS. 1 to 10, the warp yarn forms a warp yarn bundle including two or more strands of yarn, and the first zone may include the 1a zone and the 1b zone. Herein, the stretchability of the 1a zone is greater than the stretchability of the 1b zone. In the 1a zone, all strands of the warp yarn may pass over or under the weft yarn. In the 1b zone, at the position where the warp yarn and the weft yarn cross each other, each strand of the warp yarn crosses the weft yarn to form a general weave.

[0157] In yet another specific embodiment, referring again to FIGS. 1 to 10, the warp yarn may form a warp yarn bundle including two or more strands of yarn, and the second zone may include the 2a zone and the 2b zone. Herein, the stretchability of the 2a zone is greater than the stretchability of the 2b zone. In the 2a zone, all strands of the warp yarn may pass over or under the weft yarn. In the 2b zone, at the position where the warp yarn and the weft yarn cross each other, each strand of the warp yarn crosses the weft yarn to form a general weave.

[0158] For example, referring to FIGS. 2A, FIG. 2A schematically illustrates an enlarged view of the position P where the warp yarn and weft yarn cross on the lower side. Second warp yarn 232a may form a warp yarn bundle including four strands of yarn (h, i, j, k). In one or more of the 1a zone and the 2a zone, all the strands of yarn (h, i, j, k) of the warp yarn 232a may pass over the weft yarn at positions P1, P3 where the warp yarn and the weft yarn cross. In at least one of the 1b zone and the 2b zone, at a position P2, P4 where the warp yarn and the weft yarn cross each other, each strand of yarn (h, i, j, k) of the warp yarn 232a crosses the weft yarn 240a to form a general weave.
