Description

Technical Field

[0001] The present disclosure relates to a shoe upper, and more specifically, to a shoe upper including simultaneously woven inner and outer layers.Background Art

[0002] Fabrics for a shoe upper can be divided into an outer layer fabric that is exposed to the outside and an inner layer fabric that is applied to a part that directly contacts the foot, and the inner layer fabric that directly contacts the foot is mainly manufactured using soft fabric with good cushion.

[0003] In general, the shoe upper including outer and inner layers is manufactured by separately weaving the outer layer and the inner layer using the outer layer fabric and the inner layer fabric respectively, and then attaching them by heat fusion or bonding. Generally, this process is referred to as the bonding process.

[0004] Meanwhile, because the outer layer and the inner layer are separately manufactured, there is a problem of productivity deterioration, environmental pollution caused by adhesives or hot melt films, etc. used in the bonding process, and also, defects such as fabric distortion or bending due to tension imbalance between the outer layer and the inner layer in the bonding process, and fabric contamination such as adhesive marks are problematic.

[0005] Korean Registered Patent No. 10-2447575 (PTL 1) discloses a multi-layered fabric including a lower fabric, an upper fabric, and a binding part. PTL 1 has a limitation in that the structure of the upper fabric is complex, possibly resulting in decreased productivity during manufacturing, and also, weaving uses only general weaves, not twisted weaves. In addition, PTL 1 has a limitation in that the fabric, which is a knitted yarn and not a regular yarn, cannot be applied to Jacquard weaving that can express complex patterns, and further, it is a general dobby fabric and not a twisted weave that can actively ensure air permeability.CITATION LIST

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0016] In this description, fabrics are largely divided into a non-twisted weave and a twisted weave. In this description, the non-twisted weave refers to a fabric without twisted warps on the left and right sides in a plan view, and is also referred to as a general weave. The general weave refers to a fabric in which warps and wefts intersect at right angles in a plan view, and may refer to the three-way weaves represented by a plain weave, a twill weave, and a satin weave.

[0017] In this description, the twisted weave refers to a fabric in which the wefts are parallel, but the warps are twisted by alternating left and right at regular intervals in a plan view, and may refer to a leno weave that is formed as two warps including a first warp and a second warp forming one warp pair cross each other in opposite directions while twisting around the weft to form a shed and the weft passes through the shed. For the leno weave described herein, two warps forming the warp pair are crossed and twisted such that the first warp of the warp pair always goes under the weft and the second warp always goes over the weft, while the first warp always goes over the second warp.

[0018] Meanwhile, in general, weaving a fabric involves threading the warps through the heddle eyes positioned in the centers of the heddles, moving the heddles up and down to raise and lower the warps to form sheds between adjacent warps, and inserting the wefts through the sheds. Depending on the types of the shedding device, the fabrics may be classified into dobby fabrics that enable simple weaves or small patterns, and Jacquard fabrics that enable large or complex patterns.

[0019] When relatively small patterns are desired for the fabric, the dobby fabric is woven using a dobby device in which multiple heddles, which are fixed to each of, for example, 20 to 40 heddle frames (harnesses) depending on the patterns, are moved up and down together, forming sheds between the warps through the controlled movement of the heddle frames, and the wefts are inserted into the formed sheds.

[0020] The Jacquard fabric is formed by a Jacquard loom in which each warp is controlled by an independent heddle, and the loom weaves the fabric as the heddle, which is not fixed to the heddle frame but movable up and down independently, controls the heddle motion and forms a shed between the warps, and the weft is inserted into the formed shed.

[0021] In this disclosure, the shoe upper including a general weave and a twisted weave may be woven continuously in a single process by a weaving machine for weaving hybrid weave fabrics that includes a Jacquard heddle and a leno heddle. In this regard, Korean Registered Patent No. 10-1557130 (PTL 2) discloses a weaving machine for weaving hybrid weave fabrics, and a shoe upper and a shoe woven using the same.

[0022] Specifically, referring to the drawings provided in PTL 2, in the weaving machine for weaving hybrid weave fabrics, twisted weave can be woven when the leno heddle 10 is operated, and non-twisted, general weave can be woven when the Jacquard heddle 20 is operated and the leno heddle 10 is not operated. Here, rather than being fixed to the heddle frames, both the Jacquard heddle 20 and the leno heddle 10 are movable up and down independently, thus controlling the heddle motion.

[0023] Fabrics woven in a single process as described above by the weaving machine for weaving hybrid weave fabrics that includes the Jacquard heddle and the leno heddle are called leno-Jacquard fabrics. Therefore, the leno-Jacquard fabric according to the present disclosure may include a hybrid structure of a general weave and a leno weave, or may include only the general weave, or may include only the leno weave.

[0024] Meanwhile, according to the present disclosure, a one-piece shoe upper may be woven as described above, and details regarding such an integrally woven shoe upper can be found in Korean Registered Patent No. 10-1437472 (PTL 3).

[0025] Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings, and the same components described with reference to one of the drawings will not be redundantly described with reference to the other drawings.

[0029] FIG. 3B shows the compound weave of the shoe upper in a bottom view (i.e., rear view).

[0030] FIG. 4 shows photographs of a portion of the shoe upper, in which at least a portion of the shoe upper shown in FIG. 1 is applied.

[0032] FIG. 6 shows photographs of another portion of the shoe upper, in which at least a portion of the shoe upper shown in FIG. 1 is applied. Specifically, FIG. 6A is a photograph of a portion of the shoe upper seen in a plan view (i.e., front view), and FIG. 6B is a photograph of a portion of the shoe upper seen in a bottom view (i.e., rear view).

[0033] FIG. 7 shows photographs of a portion of a leno weave of the shoe upper shown in FIG. 4 in enlargement. Specifically, FIG. 7A is a photograph of a portion of the shoe upper seen in a plan view (i.e., front view) in enlargement, and FIG. 7B is a photograph of a portion of the shoe upper seen in a bottom view (i.e., rear view) in enlargement.

[0034] Referring to FIGS. 1 to 7, the shoe upper according to an embodiment of the present disclosure is formed by binding the wefts 110 and 210 and the warps 120 and 220.

[0035] The wefts 110 and 210 include the first wefts 111 and 211 and the second wefts 112 and 212 which are picked adjacently in the weaving process.

[0036] Referring to FIG. 1, in order from the bottom of the drawing, a first weft 111a is inserted in an x-axis direction and binds with the warp 120, and then a second weft 112a is also inserted in the x-axis direction and binds with the warp 120.

[0037] Meanwhile, referring to FIGS. 6 and 7, the first weft 211 and the second weft 212 are inserted adjacently but bind together by the warps 220.

[0038] Here, the shoe upper includes first pattern areas 310 and 410 having a double-weave structure formed by overlapping the first weaving areas 140 and 240 and the second weaving areas 150 and 250, in which the first weaving areas 140 and 240 formed by the first wefts 111 and 211 and the warps 120 and 220 are disposed in a first layer, and the second weaving areas 150 and 250 formed by the second wefts 112 and 212 and the warps 120 and 220 are disposed in a second layer positioned on the back surface of the first layer. Referring to FIGS. 1 to 3, FIG. 1 shows the first weaving area 140 formed by the first wefts 111 and the warps 120, and the second weaving area 150 formed by the second wefts 112 and the warps 120 on a plane, and FIG. 2 shows the first weaving area 140 and the second weaving area 150 shown in FIG. 1 individually, respectively.

[0039] Meanwhile, FIG. 3 shows a compound weave in which the simple weave structure shown in FIG. 1 is formed across a plurality of layers. Specifically, referring to FIG. 3, the first weaving area 140 formed by the first wefts 111 and the warps 120 is disposed in the first layer, and the second weaving area 150 formed by the second wefts 112 and the warps 120 is disposed in the second layer positioned on the back surface of the first layer. As a result, the first pattern area 310 having a double-weave structure formed by overlapping the first weaving area 140 and the second weaving area 150 is formed.

[0040] Referring to FIGS. 6 and 7, in the leno weave of FIGS. 6 and 7, the first weaving area 240 formed by the first wefts 211 and the warps 220 is disposed in the first layer, and the second weaving area 250 and 250' formed by the second weft 212 and the warp 220 are disposed in the second layer positioned on the back surface of the first layer. Accordingly, the first pattern areas 410 and 410' of the double-weave structure are formed by overlapping the first weaving area 240 and second weaving area 250.

[0041] Meanwhile, in a plan view, the number of weft upper points of the first wefts 111 and 211 in the first pattern areas 310 and 410 is greater than the number of weft upper points of the second wefts 112 and 212. Accordingly, the first wefts 111 and 211 are disposed in the first layer, and the second wefts 112 and 212 between the first wefts 111 and 211 and the other first wefts 111 and 211 are disposed in the second layer positioned on the back surface of the first layer.

[0042] Typically, fabric is formed by repeating a basic minimum unit of the weave vertically and horizontally. This basic minimum unit is called 'one complete repeat (1Repeat)', and this minimum structure is called 'complete weave' or 'one repeat weave'.

[0043] In addition, a diagram showing the interlacing pattern of the warps and the wefts in fabric is called a 'weave draft'. In the fabric weave draft, the warp upper point (warp-raise) marking method is generally used, which indicates the state in which the warp passes over the weft using various symbols or markings on the grid paper, and in certain cases, the weft upper point (weft-raise) marking method is also used, which indicates the state in which the weft passes over the warp.

[0044] In this regard, referring to FIG. 2, the warp upper point is represented by a black dot (M1), and the weft upper point is represented by a gray dot (M2).

[0045] Here, regarding the number of weft upper points in the first weaving area 140, the number of one complete weaves in a complete weave or one repeat weave is 8. Meanwhile, among the warps A to H binding with weft 1, the weft upper points occur on the warps B to H. Accordingly, the number of weft upper points of the first weaving area 140 is 7 / 8.

[0046] Likewise, regarding the number of weft upper points in the second weaving area 150, the number of one complete weaves in a complete weave or one complete weave is 4. Meanwhile, among the warps C to F binding with weft 9, the weft upper points occur on the warps C and G. Accordingly, the number of weft upper points of the second weaving area 150 is 1 / 4.

[0047] Likewise, regarding the number of weft upper points of the third weaving area 160 to be described below, the number of one complete weaves in a complete weave or one repeat weave is 8. Meanwhile, among the warps A to H binding with weft 17, the weft upper points occur on the warps A to H. Accordingly, the number of weft upper points of the third weaving area 160 is 1 / 8.

[0048] Accordingly, according to the principle which will be described below, the first weaving area 140 with the largest number of weft upper points is disposed at the front, followed by the second weaving area 150, and the third weaving area 160 (to be described below) is disposed at the back.

[0049] Meanwhile, referring to FIG. 6, regarding the number of weft upper points of the first weft 211 in one repeat weave R1 of the first pattern area 410, for 6 out of the total 12 warp ends of the warp pair 220 including the first warp 221 that includes three warp ends and the second warp 222 that includes three warp ends, the weft upper points occur. Accordingly, the number of weft upper points of the first weft 211 is 6 / 12.

[0050] Likewise, regarding the number of weft upper points of the second weft 212 (see FIG. 6B), for five out of the total 12 warp ends of the warp pair 220, the weft upper points occur. Accordingly, the number of weft upper points of the second weft 212 is 5 / 12.

[0051] Accordingly, according to the principle which will be described below, the first weaving area 240 with the largest number of weft upper points is disposed at the front, and then the second weaving area 250 is disposed at the back.

[0052] Meanwhile, referring to FIG. 7, regarding the number of weft upper points of the first weft 211 in one repeat weave R2 of the first pattern area 410', for 6 out of the total 12 warp ends of the warp pair 220 including the first warp 221 that includes three warp ends and the second warp 222 that includes three warp ends, the weft upper points occur. Accordingly, the number of weft upper points of the first weft 211 is 6 / 12.

[0053] Likewise, regarding the number of weft upper points of the second weft 212 (see FIG. 7B), for four out of the total 12 warp ends of the warp pair 220, the weft upper points occur. Accordingly, the number of weft upper points of the second weft 212 is 4 / 12.

[0054] Accordingly, according to the principle which will be described below, the first weaving area 240' with the largest number of weft upper points is disposed at the front, and then the second weaving area 250' is disposed at the back.

[0055] In another embodiment of the present disclosure, the first pattern area 310 is woven as a general weave by binding the wefts 110 and the warps 120.

[0056] Here, in the first pattern area 310, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process. At this time, as described above, the first wefts 111a and 111b and the second wefts 112a and 112b are woven with the warps 120 such that the number of weft upper points of the first wefts 111a and 111b is greater than the number of weft upper points of the second wefts 112a and 112b. Accordingly, by the operation of a body reed, the first wefts 111a and 111b are disposed in the first layer, and the second wefts 112a and 112b between the first weft 111a and another first weft 111b are disposed in the second layer positioned on the back surface of the first layer.

[0057] With reference to FIGS. 1 to 3 and 4, in more detail, the shoe upper is woven as a non-twisted general weave.

[0058] Specifically, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process.

[0059] In an embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted with each other at a ratio of 1:1. For example, the first weft 111a, the second weft 112a, the first weft 111b, and the second weft 112b may be alternately inserted in this order in an y-axis direction from the bottom of FIG. 1A.

[0060] In another embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted at a ratio of 2:1. For example, the first weft 111a, the first weft 111b, the second weft 112a, the first weft 111a, the first weft 111b, and the second weft 112b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A. In another embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted at a ratio of 3:1 or higher.

[0061] At this time, referring to FIG. 1A, as described above, when the first wefts 111a and 111b and the second wefts 112a and 112b are woven with the warps 120 such that the number of weft upper points of the first wefts 111a and 111b is greater than the number of weft upper points of the second wefts 112a and 112b, the first first weft 111a and second weft 112a are sequentially inserted and bind with the warp 120 (in which the third weft 113 is considered omitted), and then when the second first weft 111b is inserted and bind with the warp 120, when the body reed is operated in the -y direction, the second first weft 111b passes over the upper part of the warps B, C, E, F, G, H positioned under the first weft 111 and is placed adjacent to the first first weft 111a. Accordingly, by the operation of the body reed, the first wefts 111a and 111b are disposed in the first layer, and the second wefts 112a and 112b between the first weft 111a and another first weft 111b are disposed in the second layer positioned on the back surface of the first layer.

[0062] In another embodiment, the shoe upper further includes a second pattern area 320 formed as a general weave having a double-weave structure by overlapping a first weaving area 140' and a second weaving area 150', in which the second weaving area 150' is formed by the second wefts 112a and 112b and the warps 120 and disposed in the first layer, and the first weaving area 140' is formed by the first wefts 111a and 111b and the warps 120 and disposed in the second layer positioned on the back surface of the first layer.

[0063] FIG. 4 shows photographs of a portion of the shoe upper further including the second pattern area 320.

[0064] Here, in the second pattern area 320, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process, and are woven with the warps 120 such that the number of weft upper points of the second wefts 112a and 112b is greater than the number of weft upper points of the first wefts 111a and 111b. Accordingly, by the operation of the body reed, the second wefts 112a and 112b are disposed in the first layer, and the first wefts 111a and 111b between the second weft 112a and another second weft 112b are disposed in the second layer positioned on the back surface of the first layer.

[0065] The second pattern area 320 is configured in the same manner as the first pattern area 310, with the different number of weft upper points of the first wefts 111a and 111b and the second wefts 112a and 112b.

[0066] In another embodiment, the weft 110 further includes the third wefts 113.

[0067] FIGS. 1 to 3 and 5 schematically show the shoe upper of general weave further including the third wefts 113.

[0068] Referring to FIGS. 1 to 3 and 5, the shoe upper further includes a third pattern area 330 formed as a general weave having a triple-weave structure by overlapping the first weaving area 140 and 140', the second weaving area 150, and the third weaving area 160, in which the third weaving area 160 is formed by the third weft 113 and the warp 120 and disposed in the third layer positioned on the rearmost side.

[0069] The third pattern area 330 of FIGS. 3 and 5 has the triple-weave structure formed by overlapping the first weaving area 140, the second weaving area 150, and the third weaving area 160 sequentially from the front of the shoe upper. Referring to FIG. 5, the second weaving area 150 is not shown in FIG. 5 because the first weaving area 140 is disposed on the front surface of the shoe upper and the third weaving area 160 is disposed on the back, and the second weaving area 150 is disposed therebetween.

[0070] Meanwhile, the third pattern area 330' of FIG. 5 has the triple-weave structure formed by overlapping the second weaving area 150', the first weaving area 140', and the third weaving area 160 sequentially from the front of the shoe upper. Referring to FIG. 5, the first weaving area 140' is not shown in FIG. 5 because the second weaving area 150' is disposed on the front surface of the shoe upper and the third weaving area 160 is disposed on the back, and the first weaving area 140' is disposed therebetween.

[0071] Meanwhile, the third weft 113 is positioned and inserted between the first weft 111 and the second weft 112 in the weaving process.

[0072] Specifically, referring to FIG. 1A, in an embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 1:1:1. For example, the first weft 111a, the second weft 112a, the third weft 113a, then the first weft 111b, the second weft 112b, and the third weft 113b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A.

[0073] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 2:2:1. For example, the first weft 111a, the second weft 112a, the first weft 111b, the second weft 112b, the third weft 113a, then the first weft 111c, the second weft 112c, the first weft 111d, the second weft 112d, and the third weft 113b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A.

[0074] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 3:3:1 or higher.

[0075] At this time, the third weft 113 is woven with the warp 120 such that the number of weft upper points of the third weft 113 is the smallest compared to the number of weft upper points of the first weft 111 and the number of weft upper points of the second weft 112. As described above, the number of weft upper points of the third weaving area 160 in FIG. 2 is 1 / 8.

[0076] Accordingly, by the operation of the body reed, the third weft 113 is configured to be disposed in the third layer positioned on the rearmost side. This is the same as the configuration described above in which the first weft 111 and the second weft 112 of the first pattern area 310 are woven with the warp 120.

[0077] Specifically, referring to FIG. 1A, when the first weft 111a is inserted and then the second weft 112a is inserted, by the operation of the body reed in the -y direction, the second weft 112a with the smaller number of weft upper points is pushed from the back of the warp 120 in the -y direction and then pushed to the back (back in a z direction) of the first weft 111a with the larger number of weft upper points and positioned under the first weft 111a.

[0078] Next, when the third weft 113a is inserted, by the operation of the body reed in the -y direction, the second weft 112a with the smallest number of weft upper points is pushed from the back of the warp 120 in the -y direction, and then pushed to the back (back in the z direction) of the second weft 112a with the larger number of weft upper points to be positioned under the second weft 112a.

[0079] As shown in FIG. 5, the shoe upper including the third pattern area 330 can variously implement the patterns by the first wefts and the patterns by the second wefts on the exterior of the shoe upper, and also form the inner layer by the third wefts on the interior of the shoe upper. In this way, the outer layer and the inner layer can be woven simultaneously in a single process.

[0080] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 forming the weft 110 are alternately inserted at an insertion ratio of 2:2:1 or higher. At this time, a thickness D3 of the third weft 113 is at least two times a thickness D1 of the first weft 111 and a thickness D2 of the second weft 112.

[0081] Referring to FIGS. 1A and 5, generally, loop yarn (a decorative yarn that creates a change by forming a loop shape on the surface of the yarn) or chenille yarn (a decorative yarn that creates a hairy appearance by twisting acrylic into two warp yarns and then cutting the same) that has a soft feel, and the like are used for the inner layer wefts.

[0082] When the thickness D3 of the third weft 113, which is the inner layer weft, is relatively thicker than the other wefts, the third wefts 113 with the relatively thicker thicknesses may overlap each other if the first weft 111, the second weft 112, and the third weft 113 are inserted at the same ratio, which may cause defects due to disharmony such as the fabric becoming thicker or stiffer.

[0083] To prevent these problems, the third wefts 113 are inserted relatively less than the first wefts 111 and the second wefts 112.

[0084] In another embodiment of the present disclosure, the shoe upper includes the first pattern areas 410 and 410' woven as a leno weave.

[0085] Specifically, referring to FIGS. 4 and 6 to 7, the first weft 211 and the second weft 212 are picked adjacently in the weaving process. This is the same as previously described. That is, the first weft 211 and the second weft 212 may be alternately inserted at a ratio of 1:1, 2:1, or higher.

[0086] Meanwhile, in the first pattern areas 410 and 410', the warp 220 includes the first warp 221 and the second warp 222, in which the first warp 221 and the second warp 222 cross each other in opposite directions while twisting to form a shed. Here, the first pattern areas 410 and 410' are woven as a leno weave as the first weft 211 and the second weft 212 pass through the shed and bind.

[0087] The leno weave in the present disclosure is to be understood as previously defined.

[0088] Meanwhile, the first warp 221 includes a plurality of warp ends 221a, 221b and 221c.

[0089] A plurality of warp ends 221a, 221b and 221c are configured so as not to individually bind with the first weft 211, but to individually bind with the second weft 212. Accordingly, the first weft 211 and the second weft 212 are woven with the warp 220 such that the number of weft upper points of the first weft 211 is greater than the number of weft upper points of the second weft 212. Accordingly, the first weft 211 is disposed in the first layer, and the second weft 212 between a first weft 211a and another first weft 211b is disposed in the second layer positioned on the back surface of the first layer.

[0090] By additionally binding the second weft 212 with the plurality of warp ends 221a, 221b and 221c on the back surface of the first weft 211, the first weft 211 disposed on the front surface may be uniformly disposed without a gap of warping or opening.

[0091] In another embodiment, referring to FIG. 6, the first weft 211 passes through first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222.

[0092] Meanwhile, the second weft 212 individually binds with the plurality of warp ends 221a, 221b and 221c on the back surface of the first weft 211 to form a general weave. That is, in FIG. 6B, all of the plurality of warp ends 221a, 221b and 221c pass through the back surface of the first weft 211 (when seen in a plan view).

[0093] Specifically, each of a plurality of weft ends 212a and 212b forming the second weft 212 individually binds with the plurality of warp ends 221a, 221b and 221c to form a general weave.

[0094] This configuration is possible because all of the plurality of warp ends 221a, 221b and 221c pass through the leno heddle together while each of them is individually attached to the Jacquard heddle. That is, all of the plurality of warp ends 221a, 221b and 221c passing through the leno heddle act as one warp end 221 to form a leno weave with the weft, while each of the plurality of warp ends 221a, 221b and 221c attached to the Jacquard heddle forms a general weave with another weft.

[0095] In another embodiment, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222.

[0096] Meanwhile, the plurality of warp ends 221a, 221b and 221c cross each other in opposite directions while twisting to form a second shed, and the second weft 212 passes through the second shed and individually binds with the plurality of warp ends 221a, 221b and 221c to form a leno weave.

[0097] Specifically, the plurality of warp ends 221a, 221b and 221c cross each other in opposite directions while twisting to form a second shed, and each of the plurality of weft ends 212a and 212b forming the second weft 212 passes through the second shed and bind with each other to form a leno weave by itself.

[0098] In another embodiment, referring to FIG. 7, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222. Meanwhile, the second weft 212 simultaneously passes through a third shed formed between the plurality of warp ends 221a, 221b and 221c.

[0099] Specifically, referring to FIG. 7B, the plurality of warp ends 221a, 221b and 221c form the third shed between warp ends 221b and 221c and the warp end 221a. In FIG. 7B, the warp ends 221b and 221c passing between the first weft 211 and the second weft 121 are hidden by the second weft 121 and thus are not visible. At this time, the second weft 212 passes through the third shed formed between the warp ends 221b and 221c and the warp end 221a. In another embodiment, the weft 210 further includes a third weft 213.

[0100] FIG. 5 schematically shows the shoe upper of the leno weave further including the third weft 213.

[0101] Referring to FIG. 5, the shoe upper according to the present disclosure further includes a fourth pattern area 440 woven as a leno weave having a triple-weave structure formed by overlapping the first weaving area 240, the second weaving area 250, and a third weaving area 260, in which the third weaving area 260 is formed by the third weft 213 and the warp 220 and disposed in the third layer positioned on the rearmost side.

[0102] The fourth pattern area 440 of FIG. 5 has the triple-weave structure formed by overlapping the first weaving area 240, the second weaving area 250, and the third weaving area 260 sequentially from the front of the shoe upper. Referring to FIG. 5, the second weaving area 250 is not shown in FIG. 5 because the first weaving area 240 is disposed on the front surface of the shoe upper and the third weaving area 260 is disposed on the back, and the second weaving area 250 is disposed therebetween.

[0103] Meanwhile, the third weft 113 is positioned and inserted between the first weft 111 and the second weft 112 in the weaving process. This is the same as previously described. That is, the first weft 211, the second weft 212, and the third weft 213 may be alternately inserted at a ratio of 1:1:1, 2:2:1, or higher.

[0104] At this time, the third weft 213 is woven with the warp 220 such that the number of weft upper points of the third weft 113 is the smallest compared to the number of weft upper points of the first weft 211 and the number of weft upper points of the second weft 212. Accordingly, the third weft 213 is configured to be disposed in the third layer positioned on the rearmost side.

[0105] In another embodiment, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222. The second weft 212 simultaneously passes through a third shed formed between the plurality of warp ends 221a, 221b and 221c. In addition, the third weft 213 simultaneously passes through a fourth shed formed between the plurality of warp ends 221a, 221b and 221c. Here, the number of warp ends passing under the second weft 212 is greater than the number of warp ends passing under the third weft 213.

[0106] Specifically, the plurality of warp ends 221a, 221b and 221c form the third shed between the warp ends 221b and 221c and the warp end 221a. At this time, the second weft 212 passes through the third shed while passing over the warp ends 221b and 221c and under the warp end 221a.

[0107] Meanwhile, the plurality of warp ends 221a, 221b and 221c also form the fourth shed between the warp end 221b and the warp end 221c. At this time, the second weft 212 passes through the fourth shed while passing over the warp end 221b and under the warp end 221c. By forming a leno weave using a relatively thick inner layer weft, the decrease in air permeability due to the influence of the decorative yarn used as the inner layer weft can be prevented.

[0108] In another embodiment, referring to FIGS. 4 and 6, in the shoe upper according to the present disclosure, the first pattern areas 310 and 410 include a first pattern area-a 311 and a first pattern area-b 411.

[0109] The first pattern area-a 311 is woven as a general weave where the weft 110 and the warp 120 bind, and the first pattern area-b 411 is woven as a leno weave as the first weft 211 and the second weft 212 pass through the shed and bind.

[0110] Meanwhile, the first weft 211 and the second weft 212 participating in the weaving of the first pattern area-b 411 continuously participate in the weaving of the first pattern area-a 311. At this time, the first pattern area-a 311 and the first pattern area-b 411 are woven continuously in one process by the weaving machine for weaving hybrid weave fabrics that includes the leno heddle and the Jacquard heddle.

[0111] In another embodiment, referring to FIGS. 4 and 6, the first wefts 111 and 211 and the second wefts 112 and 212 participate in the weaving of the first pattern areas 310 and 410 and the second pattern area 320. At this time, the first pattern areas 310 and 410 and the second pattern area 320 are woven continuously in one process by the weaving machine for weaving hybrid weave fabrics that includes the leno heddle and the Jacquard heddle.

[0112] In another embodiment, referring to FIG. 5, the weft 110 further includes the third wefts 113 and 213.

[0113] Here, the shoe upper further includes fourth pattern areas 330 and 440 having a triple-weave structure.

[0114] At this time, the fourth pattern areas 330 and 440 include a fourth pattern area-a 331 and a fourth pattern area-b 441, in which the fourth pattern area-a 331 is woven as a general weave, and the fourth pattern area-b 441 is woven as a leno weave.

[0115] The third weft 213 is configured to be disposed on the third layer positioned on the rearmost side.

[0116] At this time, the first wefts 111 and 211, the second wefts 112 and 212, and the third wefts 113 and 213 continuously participate in the weaving of the fourth pattern area-a 331 and the fourth pattern area-b 441. In addition, the fourth pattern area-a 331 and the fourth pattern area-b 441 are woven continuously in one process by the weaving machine for weaving hybrid weave fabrics that includes the leno heddle and the Jacquard heddle.

Embodiment Construction

[0015]Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0016]In this description, fabrics are largely divided into a non-twisted weave and a twisted weave. In this description, the non-twisted weave refers to a fabric without twisted warps on the left and right sides in a plan view, and is also referred to as a general weave. The general weave refers to a fabric in which warps and wefts intersect at right angles in a plan view, and may refer to the three-way weaves represented by a plain weave, a twill weave, and a satin weave.

[0017]In this description, the twisted weave refers to a fabric in which the wefts are parallel, but the warps are twisted by alternating left and right at regular intervals in a plan view, and may refer to a leno weave that is formed as two warps including a first warp and a second warp forming one warp pair cross each other in opposite directions while twisting around the weft to form ...

Technical Field

[0001] The present disclosure relates to a shoe upper, and more specifically, to a shoe upper including simultaneously woven inner and outer layers.Background Art

[0002] Fabrics for a shoe upper can be divided into an outer layer fabric that is exposed to the outside and an inner layer fabric that is applied to a part that directly contacts the foot, and the inner layer fabric that directly contacts the foot is mainly manufactured using soft fabric with good cushion.

[0003] In general, the shoe upper including outer and inner layers is manufactured by separately weaving the outer layer and the inner layer using the outer layer fabric and the inner layer fabric respectively, and then attaching them by heat fusion or bonding. Generally, this process is referred to as the bonding process.

[0004] Meanwhile, because the outer layer and the inner layer are separately manufactured, there is a problem of productivity deterioration, environmental pollution caused by adhesives or hot melt films, etc. used in the bonding process, and also, defects such as fabric distortion or bending due to tension imbalance between the outer layer and the inner layer in the bonding process, and fabric contamination such as adhesive marks are problematic.

[0005] Korean Registered Patent No. 10-2447575 (PTL 1) discloses a multi-layered fabric including a lower fabric, an upper fabric, and a binding part. PTL 1 has a limitation in that the structure of the upper fabric is complex, possibly resulting in decreased productivity during manufacturing, and also, weaving uses only general weaves, not twisted weaves. In addition, PTL 1 has a limitation in that the fabric, which is a knitted yarn and not a regular yarn, cannot be applied to Jacquard weaving that can express complex patterns, and further, it is a general dobby fabric and not a twisted weave that can actively ensure air permeability.CITATION LIST

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0016] In this description, fabrics are largely divided into a non-twisted weave and a twisted weave. In this description, the non-twisted weave refers to a fabric without twisted warps on the left and right sides in a plan view, and is also referred to as a general weave. The general weave refers to a fabric in which warps and wefts intersect at right angles in a plan view, and may refer to the three-way weaves represented by a plain weave, a twill weave, and a satin weave.

[0017] In this description, the twisted weave refers to a fabric in which the wefts are parallel, but the warps are twisted by alternating left and right at regular intervals in a plan view, and may refer to a leno weave that is formed as two warps including a first warp and a second warp forming one warp pair cross each other in opposite directions while twisting around the weft to form a shed and the weft passes through the shed. For the leno weave described herein, two warps forming the warp pair are crossed and twisted such that the first warp of the warp pair always goes under the weft and the second warp always goes over the weft, while the first warp always goes over the second warp.

[0018] Meanwhile, in general, weaving a fabric involves threading the warps through the heddle eyes positioned in the centers of the heddles, moving the heddles up and down to raise and lower the warps to form sheds between adjacent warps, and inserting the wefts through the sheds. Depending on the types of the shedding device, the fabrics may be classified into dobby fabrics that enable simple weaves or small patterns, and Jacquard fabrics that enable large or complex patterns.

[0019] When relatively small patterns are desired for the fabric, the dobby fabric is woven using a dobby device in which multiple heddles, which are fixed to each of, for example, 20 to 40 heddle frames (harnesses) depending on the patterns, are moved up and down together, forming sheds between the warps through the controlled movement of the heddle frames, and the wefts are inserted into the formed sheds.

[0020] The Jacquard fabric is formed by a Jacquard loom in which each warp is controlled by an independent heddle, and the loom weaves the fabric as the heddle, which is not fixed to the heddle frame but movable up and down independently, controls the heddle motion and forms a shed between the warps, and the weft is inserted into the formed shed.

[0021] In this disclosure, the shoe upper including a general weave and a twisted weave may be woven continuously in a single process by a weaving machine for weaving hybrid weave fabrics that includes a Jacquard heddle and a leno heddle. In this regard, Korean Registered Patent No. 10-1557130 (PTL 2) discloses a weaving machine for weaving hybrid weave fabrics, and a shoe upper and a shoe woven using the same.

[0022] Specifically, referring to the drawings provided in PTL 2, in the weaving machine for weaving hybrid weave fabrics, twisted weave can be woven when the leno heddle 10 is operated, and non-twisted, general weave can be woven when the Jacquard heddle 20 is operated and the leno heddle 10 is not operated. Here, rather than being fixed to the heddle frames, both the Jacquard heddle 20 and the leno heddle 10 are movable up and down independently, thus controlling the heddle motion.

[0023] Fabrics woven in a single process as described above by the weaving machine for weaving hybrid weave fabrics that includes the Jacquard heddle and the leno heddle are called leno-Jacquard fabrics. Therefore, the leno-Jacquard fabric according to the present disclosure may include a hybrid structure of a general weave and a leno weave, or may include only the general weave, or may include only the leno weave.

[0024] Meanwhile, according to the present disclosure, a one-piece shoe upper may be woven as described above, and details regarding such an integrally woven shoe upper can be found in Korean Registered Patent No. 10-1437472 (PTL 3).

[0025] Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings, and the same components described with reference to one of the drawings will not be redundantly described with reference to the other drawings.

[0029] FIG. 3B shows the compound weave of the shoe upper in a bottom view (i.e., rear view).

[0030] FIG. 4 shows photographs of a portion of the shoe upper, in which at least a portion of the shoe upper shown in FIG. 1 is applied. Specifically, FIG. 4A is a photograph of a portion of the shoe upper seen in a plan view (i.e., front view), and FIG. 4B is a photograph of a portion of the shoe upper seen in a bottom view (i.e., rear view).

[0032] FIG. 6 shows photographs of another portion of the shoe upper, in which at least a portion of the shoe upper shown in FIG. 1 is applied. Specifically, FIG. 6A is a photograph of a portion of the shoe upper seen in a plan view (i.e., front view), and FIG. 6B is a photograph of a portion of the shoe upper seen in a bottom view (i.e., rear view).

[0033] FIG. 7 shows photographs of a portion of a leno weave of the shoe upper shown in FIG. 4 in enlargement. Specifically, FIG. 7A is a photograph of a portion of the shoe upper seen in a plan view (i.e., front view) in enlargement, and FIG. 7B is a photograph of a portion of the shoe upper seen in a bottom view (i.e., rear view) in enlargement.

[0034] Referring to FIGS. 1 to 7, the shoe upper according to an embodiment of the present disclosure is formed by binding the wefts 110 and 210 and the warps 120 and 220.

[0035] The wefts 110 and 210 include the first wefts 111 and 211 and the second wefts 112 and 212 which are picked adjacently in the weaving process.

[0036] Referring to FIG. 1, in order from the bottom of the drawing, a first weft 111a is inserted in an x-axis direction and binds with the warp 120, and then a second weft 112a is also inserted in the x-axis direction and binds with the warp 120.

[0037] Meanwhile, referring to FIGS. 6 and 7, the first weft 211 and the second weft 212 are inserted adjacently but bind together by the warps 220.

[0038] Here, the shoe upper includes first pattern areas 310 and 410 having a double-weave structure formed by overlapping the first weaving areas 140 and 240 and the second weaving areas 150 and 250, in which the first weaving areas 140 and 240 formed by the first wefts 111 and 211 and the warps 120 and 220 are disposed in a first layer, and the second weaving areas 150 and 250 formed by the second wefts 112 and 212 and the warps 120 and 220 are disposed in a second layer positioned on the back surface of the first layer. Referring to FIGS. 1 to 3, FIG. 1 shows the first weaving area 140 formed by the first wefts 111 and the warps 120, and the second weaving area 150 formed by the second wefts 112 and the warps 120 on a plane, and FIG. 2 shows the first weaving area 140 and the second weaving area 150 shown in FIG. 1 individually, respectively.

[0039] Meanwhile, FIG. 3 shows a compound weave in which the simple weave structure shown in FIG. 1 is formed across a plurality of layers. Specifically, referring to FIG. 3, the first weaving area 140 formed by the first wefts 111 and the warps 120 is disposed in the first layer, and the second weaving area 150 formed by the second wefts 112 and the warps 120 is disposed in the second layer positioned on the back surface of the first layer. As a result, the first pattern area 310 having a double-weave structure formed by overlapping the first weaving area 140 and the second weaving area 150 is formed.

[0040] Referring to FIGS. 6 and 7, in the leno weave of FIGS. 6 and 7, the first weaving area 240 formed by the first wefts 211 and the warps 220 is disposed in the first layer, and the second weaving area 250 and 250' formed by the second weft 212 and the warp 220 are disposed in the second layer positioned on the back surface of the first layer. Accordingly, the first pattern areas 410 and 410' of the double-weave structure are formed by overlapping the first weaving area 240 and second weaving area 250.

[0041] Meanwhile, in a plan view, the number of weft upper points of the first wefts 111 and 211 in the first pattern areas 310 and 410 is greater than the number of weft upper points of the second wefts 112 and 212. Accordingly, the first wefts 111 and 211 are disposed in the first layer, and the second wefts 112 and 212 between the first wefts 111 and 211 and the other first wefts 111 and 211 are disposed in the second layer positioned on the back surface of the first layer.

[0042] Typically, fabric is formed by repeating a basic minimum unit of the weave vertically and horizontally. This basic minimum unit is called 'one complete repeat (1Repeat)', and this minimum structure is called 'complete weave' or 'one repeat weave'.

[0043] In addition, a diagram showing the interlacing pattern of the warps and the wefts in fabric is called a 'weave draft'. In the fabric weave draft, the warp upper point (warp-raise) marking method is generally used, which indicates the state in which the warp passes over the weft using various symbols or markings on the grid paper, and in certain cases, the weft upper point (weft-raise) marking method is also used, which indicates the state in which the weft passes over the warp.

[0044] In this regard, referring to FIG. 2, the warp upper point is represented by a black dot (M1), and the weft upper point is represented by a gray dot (M2).

[0045] Here, regarding the number of weft upper points in the first weaving area 140, the number of one complete weaves in a complete weave or one repeat weave is 8. Meanwhile, among the warps A to H binding with weft 1, the weft upper points occur on the warps B to H. Accordingly, the number of weft upper points of the first weaving area 140 is 7 / 8.

[0046] Likewise, regarding the number of weft upper points in the second weaving area 150, the number of one complete weaves in a complete weave or one complete weave is 4. Meanwhile, among the warps C to F binding with weft 9, the weft upper points occur on the warps C and G. Accordingly, the number of weft upper points of the second weaving area 150 is 1 / 4.

[0047] Likewise, regarding the number of weft upper points of the third weaving area 160 to be described below, the number of one complete weaves in a complete weave or one repeat weave is 8. Meanwhile, among the warps A to H binding with weft 17, the weft upper points occur on the warps A to H. Accordingly, the number of weft upper points of the third weaving area 160 is 1 / 8.

[0048] Accordingly, according to the principle which will be described below, the first weaving area 140 with the largest number of weft upper points is disposed at the front, followed by the second weaving area 150, and the third weaving area 160 (to be described below) is disposed at the back.

[0049] Meanwhile, referring to FIG. 6, regarding the number of weft upper points of the first weft 211 in one repeat weave R1 of the first pattern area 410, for 6 out of the total 12 warp ends of the warp pair 220 including the first warp 221 that includes three warp ends and the second warp 222 that includes three warp ends, the weft upper points occur. Accordingly, the number of weft upper points of the first weft 211 is 6 / 12.

[0050] Likewise, regarding the number of weft upper points of the second weft 212 (see FIG. 6B), for five out of the total 12 warp ends of the warp pair 220, the weft upper points occur. Accordingly, the number of weft upper points of the second weft 212 is 5 / 12.

[0051] Accordingly, according to the principle which will be described below, the first weaving area 240 with the largest number of weft upper points is disposed at the front, and then the second weaving area 250 is disposed at the back.

[0052] Meanwhile, referring to FIG. 7, regarding the number of weft upper points of the first weft 211 in one repeat weave R2 of the first pattern area 410', for 6 out of the total 12 warp ends of the warp pair 220 including the first warp 221 that includes three warp ends and the second warp 222 that includes three warp ends, the weft upper points occur. Accordingly, the number of weft upper points of the first weft 211 is 6 / 12.

[0053] Likewise, regarding the number of weft upper points of the second weft 212 (see FIG. 7B), for four out of the total 12 warp ends of the warp pair 220, the weft upper points occur. Accordingly, the number of weft upper points of the second weft 212 is 4 / 12.

[0054] Accordingly, according to the principle which will be described below, the first weaving area 240' with the largest number of weft upper points is disposed at the front, and then the second weaving area 250' is disposed at the back.

[0055] In another embodiment of the present disclosure, the first pattern area 310 is woven as a general weave by binding the wefts 110 and the warps 120.

[0056] Here, in the first pattern area 310, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process. At this time, as described above, the first wefts 111a and 111b and the second wefts 112a and 112b are woven with the warps 120 such that the number of weft upper points of the first wefts 111a and 111b is greater than the number of weft upper points of the second wefts 112a and 112b. Accordingly, by the operation of a body reed, the first wefts 111a and 111b are disposed in the first layer, and the second wefts 112a and 112b between the first weft 111a and another first weft 111b are disposed in the second layer positioned on the back surface of the first layer.

[0057] With reference to FIGS. 1 to 3 and 4, in more detail, the shoe upper is woven as a non-twisted general weave.

[0058] Specifically, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process.

[0059] In an embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted with each other at a ratio of 1:1. For example, the first weft 111a, the second weft 112a, the first weft 111b, and the second weft 112b may be alternately inserted in this order in an y-axis direction from the bottom of FIG. 1A.

[0060] In another embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted at a ratio of 2:1. For example, the first weft 111a, the first weft 111b, the second weft 112a, the first weft 111a, the first weft 111b, and the second weft 112b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A. In another embodiment, the first wefts 111a and 111b and the second wefts 112a and 112b may be alternately inserted at a ratio of 3:1 or higher.

[0061] At this time, referring to FIG. 1A, as described above, when the first wefts 111a and 111b and the second wefts 112a and 112b are woven with the warps 120 such that the number of weft upper points of the first wefts 111a and 111b is greater than the number of weft upper points of the second wefts 112a and 112b, the first first weft 111a and second weft 112a are sequentially inserted and bind with the warp 120 (in which the third weft 113 is considered omitted), and then when the second first weft 111b is inserted and bind with the warp 120, when the body reed is operated in the -y direction, the second first weft 111b passes over the upper part of the warps B, C, E, F, G, H positioned under the first weft 111 and is placed adjacent to the first first weft 111a. Accordingly, by the operation of the body reed, the first wefts 111a and 111b are disposed in the first layer, and the second wefts 112a and 112b between the first weft 111a and another first weft 111b are disposed in the second layer positioned on the back surface of the first layer.

[0062] In another embodiment, the shoe upper further includes a second pattern area 320 formed as a general weave having a double-weave structure by overlapping a first weaving area 140' and a second weaving area 150', in which the second weaving area 150' is formed by the second wefts 112a and 112b and the warps 120 and disposed in the first layer, and the first weaving area 140' is formed by the first wefts 111a and 111b and the warps 120 and disposed in the second layer positioned on the back surface of the first layer.

[0063] FIG. 4 shows photographs of a portion of the shoe upper further including the second pattern area 320.

[0064] Here, in the second pattern area 320, the first wefts 111a and 111b and the second wefts 112a and 112b are picked adjacently in the weaving process, and are woven with the warps 120 such that the number of weft upper points of the second wefts 112a and 112b is greater than the number of weft upper points of the first wefts 111a and 111b. Accordingly, by the operation of the body reed, the second wefts 112a and 112b are disposed in the first layer, and the first wefts 111a and 111b between the second weft 112a and another second weft 112b are disposed in the second layer positioned on the back surface of the first layer.

[0065] The second pattern area 320 is configured in the same manner as the first pattern area 310, with the different number of weft upper points of the first wefts 111a and 111b and the second wefts 112a and 112b.

[0066] In another embodiment, the weft 110 further includes the third wefts 113.

[0067] FIGS. 1 to 3 and 5 schematically show the shoe upper of general weave further including the third wefts 113.

[0068] Referring to FIGS. 1 to 3 and 5, the shoe upper further includes a third pattern area 330 formed as a general weave having a triple-weave structure by overlapping the first weaving area 140 and 140', the second weaving area 150, and the third weaving area 160, in which the third weaving area 160 is formed by the third weft 113 and the warp 120 and disposed in the third layer positioned on the rearmost side.

[0069] The third pattern area 330 of FIGS. 3 and 5 has the triple-weave structure formed by overlapping the first weaving area 140, the second weaving area 150, and the third weaving area 160 sequentially from the front of the shoe upper. Referring to FIG. 5, the second weaving area 150 is not shown in FIG. 5 because the first weaving area 140 is disposed on the front surface of the shoe upper and the third weaving area 160 is disposed on the back, and the second weaving area 150 is disposed therebetween.

[0070] Meanwhile, the third pattern area 330' of FIG. 5 has the triple-weave structure formed by overlapping the second weaving area 150', the first weaving area 140', and the third weaving area 160 sequentially from the front of the shoe upper. Referring to FIG. 5, the first weaving area 140' is not shown in FIG. 5 because the second weaving area 150' is disposed on the front surface of the shoe upper and the third weaving area 160 is disposed on the back, and the first weaving area 140' is disposed therebetween.

[0071] Meanwhile, the third weft 113 is positioned and inserted between the first weft 111 and the second weft 112 in the weaving process.

[0072] Specifically, referring to FIG. 1A, in an embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 1:1:1. For example, the first weft 111a, the second weft 112a, the third weft 113a, then the first weft 111b, the second weft 112b, and the third weft 113b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A.

[0073] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 2:2:1. For example, the first weft 111a, the second weft 112a, the first weft 111b, the second weft 112b, the third weft 113a, then the first weft 111c, the second weft 112c, the first weft 111d, the second weft 112d, and the third weft 113b may be alternately inserted in this order in the y-axis direction from the bottom of FIG. 1A.

[0074] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 may be alternately inserted at a ratio of 3:3:1 or higher.

[0075] At this time, the third weft 113 is woven with the warp 120 such that the number of weft upper points of the third weft 113 is the smallest compared to the number of weft upper points of the first weft 111 and the number of weft upper points of the second weft 112. As described above, the number of weft upper points of the third weaving area 160 in FIG. 2 is 1 / 8.

[0076] Accordingly, by the operation of the body reed, the third weft 113 is configured to be disposed in the third layer positioned on the rearmost side. This is the same as the configuration described above in which the first weft 111 and the second weft 112 of the first pattern area 310 are woven with the warp 120.

[0077] Specifically, referring to FIG. 1A, when the first weft 111a is inserted and then the second weft 112a is inserted, by the operation of the body reed in the -y direction, the second weft 112a with the smaller number of weft upper points is pushed from the back of the warp 120 in the -y direction and then pushed to the back (back in a z direction) of the first weft 111a with the larger number of weft upper points and positioned under the first weft 111a.

[0078] Next, when the third weft 113a is inserted, by the operation of the body reed in the -y direction, the second weft 112a with the smallest number of weft upper points is pushed from the back of the warp 120 in the -y direction, and then pushed to the back (back in the z direction) of the second weft 112a with the larger number of weft upper points to be positioned under the second weft 112a.

[0079] As shown in FIG. 5, the shoe upper including the third pattern area 330 can variously implement the patterns by the first wefts and the patterns by the second wefts on the exterior of the shoe upper, and also form the inner layer by the third wefts on the interior of the shoe upper. In this way, the outer layer and the inner layer can be woven simultaneously in a single process.

[0080] In another embodiment, the first weft 111, the second weft 112, and the third weft 113 forming the weft 110 are alternately inserted at an insertion ratio of 2:2:1 or higher. At this time, a thickness D3 of the third weft 113 is at least two times a thickness D1 of the first weft 111 and a thickness D2 of the second weft 112.

[0081] Referring to FIGS. 1A and 5, generally, loop yarn (a decorative yarn that creates a change by forming a loop shape on the surface of the yarn) or chenille yarn (a decorative yarn that creates a hairy appearance by twisting acrylic into two warp yarns and then cutting the same) that has a soft feel, and the like are used for the inner layer wefts.

[0082] When the thickness D3 of the third weft 113, which is the inner layer weft, is relatively thicker than the other wefts, the third wefts 113 with the relatively thicker thicknesses may overlap each other if the first weft 111, the second weft 112, and the third weft 113 are inserted at the same ratio, which may cause defects due to disharmony such as the fabric becoming thicker or stiffer.

[0083] To prevent these problems, the third wefts 113 are inserted relatively less than the first wefts 111 and the second wefts 112.

[0084] In another embodiment of the present disclosure, the shoe upper includes the first pattern areas 410 and 410' woven as a leno weave.

[0085] Specifically, referring to FIGS. 4 and 6 to 7, the first weft 211 and the second weft 212 are picked adjacently in the weaving process. This is the same as previously described. That is, the first weft 211 and the second weft 212 may be alternately inserted at a ratio of 1:1, 2:1, or higher.

[0086] Meanwhile, in the first pattern areas 410 and 410', the warp 220 includes the first warp 221 and the second warp 222, in which the first warp 221 and the second warp 222 cross each other in opposite directions while twisting to form a shed. Here, the first pattern areas 410 and 410' are woven as a leno weave as the first weft 211 and the second weft 212 pass through the shed and bind.

[0087] The leno weave in the present disclosure is to be understood as previously defined.

[0088] Meanwhile, the first warp 221 includes a plurality of warp ends 221a, 221b and 221c.

[0089] A plurality of warp ends 221a, 221b and 221c are configured so as not to individually bind with the first weft 211, but to individually bind with the second weft 212. Accordingly, the first weft 211 and the second weft 212 are woven with the warp 220 such that the number of weft upper points of the first weft 211 is greater than the number of weft upper points of the second weft 212. Accordingly, the first weft 211 is disposed in the first layer, and the second weft 212 between a first weft 211a and another first weft 211b is disposed in the second layer positioned on the back surface of the first layer.

[0090] By additionally binding the second weft 212 with the plurality of warp ends 221a, 221b and 221c on the back surface of the first weft 211, the first weft 211 disposed on the front surface may be uniformly disposed without a gap of warping or opening.

[0091] In another embodiment, referring to FIG. 6, the first weft 211 passes through first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222.

[0092] Meanwhile, the second weft 212 individually binds with the plurality of warp ends 221a, 221b and 221c on the back surface of the first weft 211 to form a general weave. That is, in FIG. 6B, all of the plurality of warp ends 221a, 221b and 221c pass through the back surface of the first weft 211 (when seen in a plan view).

[0093] Specifically, each of a plurality of weft ends 212a and 212b forming the second weft 212 individually binds with the plurality of warp ends 221a, 221b and 221c to form a general weave.

[0094] This configuration is possible because all of the plurality of warp ends 221a, 221b and 221c pass through the leno heddle together while each of them is individually attached to the Jacquard heddle. That is, all of the plurality of warp ends 221a, 221b and 221c passing through the leno heddle act as one warp end 221 to form a leno weave with the weft, while each of the plurality of warp ends 221a, 221b and 221c attached to the Jacquard heddle forms a general weave with another weft.

[0095] In another embodiment, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222.

[0096] Meanwhile, the plurality of warp ends 221a, 221b and 221c cross each other in opposite directions while twisting to form a second shed, and the second weft 212 passes through the second shed and individually binds with the plurality of warp ends 221a, 221b and 221c to form a leno weave.

[0097] Specifically, the plurality of warp ends 221a, 221b and 221c cross each other in opposite directions while twisting to form a second shed, and each of the plurality of weft ends 212a and 212b forming the second weft 212 passes through the second shed and bind with each other to form a leno weave by itself.

[0098] In another embodiment, referring to FIG. 7, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222. Meanwhile, the second weft 212 simultaneously passes through a third shed formed between the plurality of warp ends 221a, 221b and 221c.

[0099] Specifically, referring to FIG. 7B, the plurality of warp ends 221a, 221b and 221c form the third shed between warp ends 221b and 221c and the warp end 221a. In FIG. 7B, the warp ends 221b and 221c passing between the first weft 211 and the second weft 121 are hidden by the second weft 121 and thus are not visible. At this time, the second weft 212 passes through the third shed formed between the warp ends 221b and 221c and the warp end 221a. In another embodiment, the weft 210 further includes a third weft 213.

[0100] FIG. 5 schematically shows the shoe upper of the leno weave further including the third weft 213.

[0101] Referring to FIG. 5, the shoe upper according to the present disclosure further includes a fourth pattern area 440 woven as a leno weave having a triple-weave structure formed by overlapping the first weaving area 240, the second weaving area 250, and a third weaving area 260, in which the third weaving area 260 is formed by the third weft 213 and the warp 220 and disposed in the third layer positioned on the rearmost side.

[0102] The fourth pattern area 440 of FIG. 5 has the triple-weave structure formed by overlapping the first weaving area 240, the second weaving area 250, and the third weaving area 260 sequentially from the front of the shoe upper. Referring to FIG. 5, the second weaving area 250 is not shown in FIG. 5 because the first weaving area 240 is disposed on the front surface of the shoe upper and the third weaving area 260 is disposed on the back, and the second weaving area 250 is disposed therebetween.

[0103] Meanwhile, the third weft 113 is positioned and inserted between the first weft 111 and the second weft 112 in the weaving process. This is the same as previously described. That is, the first weft 211, the second weft 212, and the third weft 213 may be alternately inserted at a ratio of 1:1:1, 2:2:1, or higher.

[0104] At this time, the third weft 213 is woven with the warp 220 such that the number of weft upper points of the third weft 113 is the smallest compared to the number of weft upper points of the first weft 211 and the number of weft upper points of the second weft 212. Accordingly, the third weft 213 is configured to be disposed in the third layer positioned on the rearmost side.

[0105] In another embodiment, the first weft 211 passes through the first shed formed by all of the plurality of warp ends 221a, 221b and 221c and the second warp 222. The second weft 212 simultaneously passes through a third shed formed between the plurality of warp ends 221a, 221b and 221c. In addition, the third weft 213 simultaneously passes through a fourth shed formed between the plurality of warp ends 221a, 221b and 221c. Here, the number of warp ends passing under the second weft 212 is greater than the number of warp ends passing under the third weft 213.

[0106] Specifically, the plurality of warp ends 221a, 221b and 221c form the third shed between the warp ends 221b and 221c and the warp end 221a. At this time, the second weft 212 passes through the third shed while passing over the warp ends 221b and 221c and under the warp end 221a.

[0107] Meanwhile, the plurality of warp ends 221a, 221b and 221c also form the fourth shed between the warp end 221b and the warp end 221c. At this time, the second weft 212 passes through the fourth shed while passing over the warp end 221b and under the warp end 221c. By forming a leno weave using a relatively thick inner layer weft, the decrease in air permeability due to the influence of the decorative yarn used as the inner layer weft can be prevented.

[0108] In another embodiment, referring to FIGS. 4 and 6, in the shoe upper according to the present disclosure, the first pattern areas 310 and 410 include a first pattern area-a 311 and a first pattern area-b 411.

[0109] The first pattern area-a 311 is woven as a general weave where the weft 110 and the warp 120 bind, and the first pattern area-b 411 is woven as a leno weave as the first weft 211 and the second weft 212 pass through the shed and bind.

[0110] Meanwhile, the first weft 211 and the second weft 212 participating in the weaving of the first pattern area-b 411 continuously participate in the weaving of the first pattern area-a 311. At this time, the first pattern area-a 311 and the first pattern area-b 411 are woven continuously in one process by the weaving machine for weaving hybrid weave fabrics that includes the leno heddle and the Jacquard heddle.

[0111] In another embodiment, referring to FIGS. 4 and 6, the first wefts 111 and 211 and the second wefts 112 and 212 participate in the weaving of the first pattern areas 310 and 410 and the second pattern area 320. At this time, the first pattern areas 310 and 410 and the second pattern area 320 are woven continuously in one process by the weaving machine for weaving hybrid weave fabrics that includes the leno heddle and the Jacquard heddle.

[0112] In another embodiment, referring to FIG. 5, the weft 110 further includes the third wefts 113 and 213.

[0113] Here, the shoe upper further includes fourth pattern areas 330 and 440 having a triple-weave structure.

[0114] At this time, the fourth pattern areas 330 and 440 include a fourth pattern area-a 331 and a fourth pattern area-b 441, in which the fourth pattern area-a 331 is woven as a general weave, and the fourth pattern area-b 441 is woven as a leno weave.

[0115] The third weft 213 is configured to be disposed on the third layer positioned on the rearmost side.

[0116] At this time, the first wefts 111 and 211, the second wefts 112 and 212, and the third wefts 113 and 213 continuously participate in the weaving of the fourth pattern area-a 331 and the fourth pattern area-b 441.
