Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a woven shoe upper with a knitted style. Background Technology

[0002] Knitted shoe uppers are favored by the market for their comfortable fit and lightweight silhouette, but their production efficiency is low and their cost is high. In contrast, woven fabrics have the advantages of high production efficiency, significant cost advantages, and strong abrasion resistance, and are widely used in the footwear materials industry. However, traditional woven fabrics have the following limitations: the mesh structure of fixed woven fabrics is mainly square, lacking design variation and aesthetics, and failing to meet consumers' pursuit of a knitted visual effect; they are generally not elastic, affecting the actual wearing experience of the product, putting them at a disadvantage in the high-end market competition.

[0003] Chinese patent application number 202122455147.8 discloses a quadrilateral mesh woven fabric, comprising a main body of fabric with multiple continuously and evenly distributed square units on the front side. Each square unit has overlapping and tightly joined top, bottom, left, and right boundaries, and each square unit includes four evenly distributed square mesh holes. This invention improves the breathability of the fabric by incorporating mesh holes in the woven structure, and by evenly distributing four square mesh holes within a single square unit, it maintains the fabric's strength and durability while enhancing breathability. However, this mesh fabric has a simple twisted structure and a monotonous surface finish.

[0004] Chinese Patent Application No. 202220997937.0 discloses a high-strength woven shoe upper fabric, comprising a woven fabric layer, a top surface of which is covered with a sprayed coating layer, and the bottom surface of the woven fabric layer is fixed to the top surface of an inner lining layer. An inner padding layer is fixedly disposed on the bottom surface of the inner lining layer, and ventilation holes are provided through the inner padding layer. This high-strength woven shoe upper fabric employs a novel structural design, improving the structure of the warp and weft threads of the woven fabric, greatly enhancing its structural strength. Combined with the surface spraying layer, it significantly slows down the wear rate of the woven fabric, ensuring its long-term stable use. However, this shoe upper fabric suffers from low elasticity and poor comfort. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a woven shoe upper with a knitted style, which solves the problems of the existing woven mesh fabric having a simple twisted structure, monotonous fabric effect, low elasticity and poor comfort.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A woven upper with a knitted appearance includes a fabric body comprising a polygonal woven mesh structure and a raised texture structure; the fabric body is woven from warp and weft yarns, the warp yarns comprising skein warp and ground warp, wherein the skein warp and ground warp required to form one yarn hole are defined as a skein group, wherein both the skein warp and ground warp in a skein group are three 0.2mm high-low temperature TPU composite low-elasticity monofilaments, and the interlacing method of a skein group is three-twist-three, wherein the skein warp and ground warp are inserted together into a reed; the weft yarns include a first weft yarn, a second weft yarn, and a third weft yarn.

[0008] Furthermore, the polygonal woven mesh structure is formed by: after weaving in a first weft yarn, two or more strands are simultaneously twisted once; after weaving in a second or third weft yarn in the next row, a ribbing structure is simultaneously twisted once.

[0009] Furthermore, the polygonal woven mesh structure is rhomboid or hexagonal.

[0010] Furthermore, the raised texture structure is formed by using a controllable design of the weft yarn float length on the surface of the fabric body, so that the weft stitch points are continuously arranged on the surface of the fabric body. During the shaping process, some areas will show raised texture on the surface under the shrinkage effect of 0.2mm high and low temperature TPU composite low elastic monofilament.

[0011] Furthermore, the first weft yarn is polyester DTY 150D / 36F*2 semi-dull low-elastic core-spun yarn; the semi-dull low-elastic core-spun yarn includes a first core yarn and a first covering yarn, the first core yarn is 180D spandex, and the first covering yarn is 840D polyester.

[0012] Furthermore, both the second and third weft yarns are polyester low-elasticity yarns, and the specifications of the polyester low-elasticity yarns are polyester DTY 333dtex / 96F / 2*3 semi-dull low-elasticity yarns. The polyester low-elasticity yarns are treated with S-twist, and the twist is 80 twists / meter.

[0013] Furthermore, the first and second weft yarns are white, and the third weft yarn is black.

[0014] Furthermore, the 0.2mm high and low temperature TPU composite low elastic monofilament is colorless and transparent.

[0015] Furthermore, the specification of the 0.2mm high and low temperature TPU composite low elastic monofilament is 400D.

[0016] Furthermore, the number of warp threads is 4362, the number of shuttles for the first weft yarn is 109, the number of shuttles for the second weft yarn is 219, and the number of shuttles for the third weft yarn is 108.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0018] 1. The core-shell type high- and low-temperature TPU composite low-elasticity monofilament is selected, with 190℃ high-melting-point TPU as the core layer and 170℃ low-melting-point TPU as the sheath layer. When the setting temperature is higher than 170℃, the core layer does not melt, while the sheath layer melts and solidifies, bonding the warp and weft threads of the woven fabric and stabilizing the mesh shape.

[0019] 2. The three-twisted weaving method is adopted. The warp yarns are all transparent high- and low-temperature TPU composite low-elastic monofilaments. The ratio of twisted warp to ground warp in a twisted group is 3:3. The two twist each other to make the surface present clear and evenly distributed yarn holes.

[0020] 3. 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.

[0021] 4. By using polyester-coated spandex as the 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.

[0022] 5. By utilizing the controllable design of the weft yarn floating on the surface, the weft weft points are continuously arranged on the surface. During the setting process, under the shrinkage effect of TPU, a slight raised texture is revealed on the surface.

[0023] 6. Utilize jacquard partitioning design to distribute different tissues in different locations.

[0024] 7. The pre-setting process uses a high-temperature, rapid setting method, while the finished product stentering uses a slightly lower temperature, slower setting method. This ensures the fabric surface is stable during the final setting process without damaging the internal structure of the raw materials, thus extending the fabric's lifespan. The fabric is woven from colored yarn and requires no post-dyeing treatment; it only needs to undergo a flat-width wash. Simultaneously, auxiliaries are used to remove oil and modify the fabric.

[0029] The polygonal woven mesh structure is formed as follows: after weaving in a first weft yarn, two or more strands are simultaneously twisted once; a second weft yarn is woven into the next row while simultaneously twisting once; then, after weaving in a first weft yarn, two or more strands are simultaneously twisted once; a third weft yarn is woven into the next row while simultaneously twisting once; the polygonal woven mesh structure is rhomboid.

[0030] The raised texture is formed by using a controllable design of the weft yarn float on the surface of the fabric body, so that the weft points are continuously arranged on the surface of the fabric body. During the shaping process, some areas will show raised texture on the surface under the shrinkage effect of 0.2mm high and low temperature TPU composite low elastic monofilament.

[0032] The above-described method for preparing a knitted shoe upper includes the following steps:

[0033] (1) Selection of raw yarn

[0034] The raw materials include the following specifications: 0.2mm high and low temperature TPU composite low elastic monofilament, polyester DTY 150D / 36F*2 semi-dull low elastic core-spun yarn, and polyester low elastic yarn;

[0035] The 0.2mm high and low temperature TPU composite low elastic monofilament has a specification of 400D; the semi-dull low elastic core-spun yarn includes a first core yarn and a first covering yarn, the first core yarn is 180D spandex, and the first covering yarn is 840D polyester; the polyester low elastic yarn has a specification of polyester DTY 333dtex / 96F / 2*3 semi-dull low elastic yarn, and the polyester low elastic yarn is treated with S-twist, with a twist of 80 twists / meter;

[0036] (2) Weaving

[0037] The raw yarn is woven into a greige fabric using a yarn frame weaving heddle machine. The greige fabric includes a polygonal woven mesh structure 2 and a raised texture structure 3. The greige fabric is woven from warp and weft yarns.

[0038] (3) Pre-order type

[0039] The fabric is pre-shaped at 190°C. The pre-shaped machine is an EAG-2000-CBR-0 Ligen pre-shaped machine. The input speed of the fabric is set at 15 yards / min. The fabric is fed into the pre-shaped machine along the reverse weave direction. First, the fabric is stretched or contracted to the pre-shaped size by the overfeed roller device and the pin chain stretching device. Then, it is pre-shaped by multiple dry heat sealed oven devices. After the pre-shaped fabric is cooled, the pre-shaped process is completed.

[0040] The setting machine uses high-temperature hot air setting technology, which makes hot air act evenly on both sides of the fabric. When the temperature inside the closed oven of the setting machine is higher than the glass transition temperature of the fabric, the polymer inside the fiber raw material is reorganized, thereby changing the surface dimensions of the fabric.

[0041] (4) Flat-width washing

[0042] First, the fabric is absorbed at 60°C in box one. Then, the temperature is raised to 90°C in box two. Next, 4% degreasing agent Z41, 2% degreasing agent Z83, and 1% chelating dispersant are added, with the remainder being water. The fabric is then heated in boxes three and four, transferred to box five, and the temperature is lowered to 60°C. Finally, the temperature is lowered to room temperature in box six for squeezing and drying. The fabric is then discharged.

[0043] (5) Tensioning and Shaping

[0044] The stenter is set using an EAG-2300-CBR-0 stenter, with the temperature set at 180℃ and the fabric input speed set at 15 yards / min.

[0045] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
