Description

TECHNICAL FIELD

[0001] The utility model relates to weaving technology field especially relates to a heddle weaving of upper is used in fabric. BACKGROUND

[0002] The feature of the woven shoe upper lies in the tight structure formed by the interlacing of warp and weft. This structure endows the shoe upper with excellent strength and durability. Compared with the knitted shoe upper, the woven shoe upper is more flat and smooth, and is suitable for making shoes that require high support and stability, such as sports shoes, formal shoes, and some outdoor shoes.

[0003] The heddle weaving process forms a stable and breathable grid structure through the interlacing of weft yarns in and out between warp yarns. This structure enables the shoe upper to create more regular and breathable mesh holes while maintaining toughness and stability, thereby improving the comfort and breathability of the shoe. The drawback of the traditional heddle weaving process is that the warp yarns can only be pre-made into a disc head according to product process requirements. The disc head is made of more than 20,000 TPEE or PET yarns of the same specification and color, which has a long construction period, high cost, and large waste. Changing the warp design requires a large time and material cost.

[0004] Chinese patent application No. 202210416469.8 discloses a lightweight and breathable shoe upper fabric and a lightweight and high-elasticity fiber spinning process. The fabric is woven by a through-hole heddle weaving method. The ground warp in the warp yarns includes PEBA fiber, and the heddle yarns are any one of PEBA fiber, TPEE fiber, TPU fiber, polyester, spandex, nylon, and polyolefin fiber. The weft yarns include one or more of PEBA fiber, TPEE fiber, TPU fiber, polyester, spandex, nylon, and polyolefin fiber. The weight percentage of PEBA fiber in the fabric is 18-100%. In the fiber spinning process, PEBA elastomer uses long-chain nylon 11, long-chain nylon 12, nylon 56, etc. as the hard segment, and polytetrahydrofuran, polypropylene glycol, and polyethylene glycol as the soft segment. The advantages of this invention are: under the same weaving method, the fabric weight can be effectively reduced by 20%, while maintaining the tensile strength and tear strength of the warp and weft directions, the bursting strength is much higher than that of traditional fabrics, the low-temperature bending resistance is better, there is no crack after 40,000 times of low-temperature bending, the use environment is wider, the transparency is higher, and the visual appearance is better. However, the warp direction cannot be changed at will, and a large time and material cost is required to change the warp design.

[0005] Chinese patent application No. 202420619155.2 discloses a woven fabric and a shoe comprising the woven fabric, comprising: a weft yarn group, a warp yarn group and a functional yarn group; the weft yarn group is interlaced with the warp yarn group, and the weft yarn group and the warp yarn group are uniformly spaced; the functional yarn group passes under the weft yarn group from both sides of the warp yarn group and is pressed on the upper surface of the warp yarn group, so that the adjacent two weft yarn groups and the adjacent two warp yarn groups are jointly arranged to form a gap hole. The functional yarn group floats on the upper layer of the warp yarn group, and is interlaced with the weft yarn groups on the left and right sides of the warp yarn group, forming a hole with a gap, which has certain air permeability under the premise of ensuring firmness and not easy to deform, thereby improving the comfort during wearing; it is more suitable for off-road runners to use, can cope with various scenes and complex road conditions in off-road running, has improvement in durability, can prolong the service mission of the upper, and is also lighter and thinner, realizing the demand of runners for light weight. However, the mesh of the upper does not have a rhombus or hexagonal shape, and the upper does not have a raised texture. Utility model content

[0006] Therefore, in view of the above problems, the utility model provides a shuttle weaving harness fabric for an upper, solves the problem that the warp yarn cannot be changed at will during the weaving of the existing upper, the mesh of the upper does not have a rhombus or hexagonal shape, and the upper does not have a raised texture.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] A shuttle weaving harness fabric for an upper, comprising a fabric body, the fabric body comprising a polygonal shuttle weaving mesh organization and a raised texture organization; the fabric body is woven from warp yarn and weft yarn, the weft yarn comprising first weft yarn, second weft yarn, third weft yarn, fourth weft yarn, fifth weft yarn and sixth weft yarn; the warp yarn comprising harness warp and ground warp, the ground warp comprising first ground warp and second ground warp, the harness warp and the ground warp required to define a yarn hole being a harness group, one harness warp and one first ground warp in one harness group, i.e. the harness warp: first ground warp = 1:1, the interlacing mode of one harness group being one harness one, the second ground warp being five 0.12mm TPEE lustrous crease-resistant filaments;

[0009] The fabric body adopts two weaving methods of harness weaving and local harness weaving, the harness weaving being that the harness warp is controlled by the jacquard needle holes on both sides of the harness needle, the left side being jacquard, the harness needle being on the left side of the harness needle, the right side being jacquard, the harness needle being on the right side of the harness needle; the left and right jacquard makes the harness needle use the weft yarn to flip left and right to fix;

[0010] The local harness weaving being that the harness needle and the weft yarn are interlaced perpendicularly with each other, the harness needle single-side jacquard being hidden in the reverse side, so that the harness needle is not exposed on the front side and is in the non-harness state;

[0011] The left side jacquard is specifically as follows: when the left side jacquard is needed, the jacquard needle hole located at the left side of the binding needle lifts the corresponding warp yarn (including the binding warp and the ground warp); the binding needle is at the left side of the binding needle, so that the binding warp is turned to the left under the action of the left side jacquard needle hole; meanwhile, the weft yarn is introduced and interwoven with the turned binding warp, to form a specific pattern.

[0012] The right side jacquard is specifically as follows: when the right side jacquard is needed, the jacquard needle hole located at the right side of the binding needle lifts the corresponding warp yarn; the binding needle is at the right side of the binding needle, so that the binding warp is turned to the right under the action of the right side jacquard needle hole; similarly, the weft yarn is introduced and interwoven with the turned binding warp, to form another side pattern.

[0013] The combination of the left and right jacquards can realize the left and right turning of the binding warp; through different arrangements and combinations of the jacquard needle holes, complex and changeable pattern designs can be created; in this process, the binding warp is firmly fixed in the fabric under the interweaving action of the weft yarn, to form a unique twisting structure.

[0014] Further, the weaving method of the polygonal weft-knitted mesh fabric is as follows: the binding warp and the ground warp are inserted into one reed together; two or more than two binding groups are staggered and the weft yarn and the ground yarn are twisted at the same time, that is, one weft yarn is inserted in one course and twisted at the same time, and three or more than three odd weft yarns are inserted in the next course and twisted at the same time.

[0015] Further, the weaving method of the convex texture fabric is as follows: the controllable design of the weft yarn float on the surface of the fabric body makes the weft yarn points continuously arranged on the surface of the fabric body, and part of the area is exposed on the surface under the shrinkage action of the TPU high-low temperature composite low-elasticity monofilament and the TPU light high-elasticity monofilament in the setting process, to form a convex texture on the surface.

[0016] The weft yarn float refers to the continuous non-interwoven part of the yarn on the fabric surface; the raw materials of the TPU high-low temperature composite low-elasticity monofilament and the TPU light high-elasticity monofilament are thermoplastic polyurethane, which will shrink under the action of heat and external force in the setting process. The shrinkage will cause the part of the fabric in contact with the TPU to be extruded and stretched, so as to form a convex or concave texture effect on the surface of the fabric.

[0017] Further, the binding warp and the first ground warp are 0.20 mm TPU high-low temperature composite low-elasticity monofilament.

[0018] The TPU high-low temperature composite low-elasticity monofilament features a core-sheath structure, with a 190℃ high-melting-point TPU core and a 170℃ low-melting-point TPU sheath. When the setting temperature exceeds 170℃, the core does not melt, while the sheath melts and solidifies, bonding the warp and weft threads and fixing the mesh shape. TPU is transparent, soft, and durable, preserving the original color of the fabric to the maximum extent while enhancing its strength and abrasion resistance. The high-low temperature composite low-elasticity monofilament has a specification of 400D, ensuring that it will not break even after multiple continuous twisting processes.

[0019] Furthermore, the fifth weft yarn is a 0.20mm TPU bright high-elastic monofilament, and the first, second, third, fourth and sixth weft yarns are all polyester DTY167dtex / 36F semi-glossy high-elastic yarn.

[0020] Furthermore, the warp, ground warp, and fifth weft yarn are all transparent.

[0021] Furthermore, the specification of the 0.20mm TPU high and low temperature composite low elastic monofilament is 400D.

[0022] Furthermore, the specification of the 0.20mm TPU bright high-elastic monofilament is 400D.

[0023] Furthermore, the number of warp yarns in the twisted warp is 2568, and the number of warp yarns in the ground warp is 6430; the number of shuttles for the first weft yarn, the second weft yarn, the third weft yarn, and the fourth weft yarn is 539, the number of shuttles for the fifth weft yarn is 179, and the number of shuttles for the sixth weft yarn is 40.

[0024] Furthermore, the first and second weft yarns are pink, the third and fourth weft yarns are white, and the sixth weft yarn is black.

[0025] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0026] 1. The fabric body adopts a skein weaving method. The warp skein is made of transparent TPU high and low temperature composite low elastic monofilament. The ratio of skein warp to ground warp in a skein is 1:1. The two are twisted together to make the surface present clear and evenly distributed yarn holes.

[0027] 2. By misaligning two or more twisted groups and simultaneously twisting the yarn structure and ribbing structure, the traditional square shape of the woven yarn hole is broken, so that the mesh shape presents a rhombus or hexagon, just like the mesh of a knitted net.

[0028] 3. Using TPU glossy high-elastic monofilament as the fifth weft yarn, the shoe achieves elasticity in areas such as the toe, while maintaining strong support in other areas, making it more accommodating to different foot shapes.

[0029] 4. The controllable design of the weft yarn floating on the surface makes the weft structure points continuous; and the weft structure points are arranged on the surface and show slight convex texture on the surface under the shrinkage of the TPU material during setting.

[0030] 5. The jacquard partition design is used to distribute different structures in different positions.

[0031] 6. The shoe upper fabric product woven by the creel and shuttle weaving heddle braid equipment has good air permeability, better wrapping effect, more brilliant color and higher economic value, has a shorter product development cycle and more stable product quality; compared with the traditional shuttle weaving heddle braid product, while meeting the shoe upper air permeability function of the local opening of the shuttle weaving heddle braid, the wrapping capacity can be improved by 30% and the product weight can be reduced by 20% due to the participation of different specifications of warp creel yarns; in the process, more than 20,000 disc head processes are not needed, only the corresponding special yarn hanging operation is needed, and the average working period can be reduced by more than 2 days.
