Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile technology especially relates to a concave-convex three-dimensional warp knitting fabric. BACKGROUND

[0002] Traditional textiles have been unable to meet the changing consumer concepts, and new materials, new technologies and new processes need to be introduced to empower traditional textiles with technological innovation. At present, the concave-convex effect of warp-knitted fabric is mostly achieved by using the high-elasticity and high-shrinkage properties of spandex cover yarn combined with weaving processes to make the fabric achieve the concave-convex effect. However, such warp-knitted concave-convex fabric has the disadvantages of easy aging and breaking of spandex, easy color migration of dyeing, easy exposure of spandex on the fabric surface, and excessive overall elasticity, which is not suitable for use as a warp-knitted shoe upper.

[0003] Chinese patent application No. 202322142350.9 discloses a warp-knitted sun-protective fabric, which is a warp plain weave made of nylon, with nylon being 40D-100D nylon textured yarn and the weave structure being 1-0 / 3-4 / / . The fabric has a concave-convex shape, with yarn densities being 70-100 stitches / inch in the horizontal direction and 70-100 stitches / inch in the vertical direction. It has good sun-protective properties and also has the advantages of softness, good hand feeling and comfort. However, the fabric has the problems of easy aging and breaking and easy exposure on the fabric surface.

[0004] Chinese patent application No. 202221276104.1 discloses a texture-sensitive knitted warp-knitted fabric, which is knitted by three-needle bar organization. The three-needle bar organization specifically includes front comb GB1, middle comb GB2 and three comb GB3. The weave structure of front comb GB1 includes 10 / 12 / / and 10 / 23 / / , the weave structure of middle comb GB2 is 10 / 23 / / , and the weave structure of three comb GB3 is double-needle bar warp organization 02 / 31 / / . The texture-sensitive knitted warp-knitted fabric provided by the utility model has the advantages of smooth and crisp texture, clear concave-convex texture, no wrinkles and bulges when stretched and recovered, always keeping a close fit, no raw edges and rolled edges when cutting, and no scattering effect when cutting. However, the fabric does not have the effects of breathable mesh and comfortable plain weave. SUMMARY

[0005] Therefore, in view of the above problems, the utility model provides a concave-convex three-dimensional warp-knitted fabric to solve the problems of easy aging and breaking of existing concave-convex three-dimensional warp-knitted fabric, exposure on the fabric surface, and lack of breathable mesh and comfortable plain weave.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0031] Furthermore, the GB5 is used to connect the front and rear needle bed coils to form a three-layer mesh structure.

[0032] Furthermore, GB6 is used to control the coil direction and assist in forming the mesh.

[0033] Furthermore, the Jacquard comb uses a coiled active warp feeding mechanism.

[0034] Furthermore, the TPEE high-shrinkage, fold-resistant yarn is looped in the front and back needle mattress yarns to form a recessed area; the TPEE is only looped in the front needle mattress yarns to form a raised area.

The rear of the jacquard guide bar has a single filament ground comb, GB5, which is used to connect the front and rear needle bed loops to form a three-layer mesh structure, and a chain knitting ground comb, GB6, which is used to control the loop direction and assist in forming the mesh. The jacquard guide bar selects a disc head positive type warp let-off mechanism, the yarn tension is balanced, and longitudinal streak defects do not occur. The front jacquard guide bars JB3.1 and JB3.2 pass through the TPEE high shrinkage and folding resistant yarn, the concave and convex effects of the fabric are realized by using the material properties and the jacquard guide bar needle selection technology, the TPEE high shrinkage and folding resistant yarn is looped on the front and rear needle beds, due to the high shrinkage characteristics of the TPEE high shrinkage and folding resistant yarn, the two fabric surfaces on the bottom are tightened to form a concave area, and the TPEE high shrinkage and folding resistant yarn is looped on the front needle bed only to form a convex area, and the concave area and the convex area jointly form the concave and convex three-dimensional pattern. The rear jacquard guide bars JB4.1 and JB4.2 pass through the polyester DTY100D / 48F light mesh yarn, and can form breathable mesh holes of different sizes and lengths in any area. The polyester and yarn configuration on the surface and the bottom of the fabric makes the surface of the fabric shallow, and another color can be displayed from the mesh, so that the color and the level are more rich.
