Technical Field

[0001] The utility model relates to the technical field of textiles, and particularly relates to a warp knitted fabric with a two-color grid structure. Background Art

[0002] At present, the market not only requires the shoe material fabric to have excellent physical properties such as tensile strength and abrasion resistance, but also a unique appearance. The breathable two-color single-sided shoe upper usually achieves the two-color effect through post-treatment methods such as printing on the breathable base layer, or through the two-color effect formed by the interweaving of yarns. However, the former printing is easy to fall off, and the latter is prone to impure color due to the overlap of coils of two colors. Summary of the Utility Model

[0006] The second jacquard layer includes a third color area and a fourth color area; in the third color area, the first jacquard comb structure changes to a plush stitch structure, and the second jacquard comb structure changes to a weft insertion structure; in the fourth color area, the second jacquard comb structure changes to a plush stitch structure, and the first jacquard comb structure changes to a weft insertion structure.

[0007] Wherein, the basic structures of the first jacquard comb structure and the second jacquard comb structure are warp plain structures.

[0008] Wherein, the thickness of the first jacquard layer is greater than that of the second jacquard layer.

[0009] Wherein, the grid base layer is composed of a first ground comb structure, a second ground comb structure, and a third ground comb structure.

[0010] Wherein, the first ground comb structure and the second ground comb structure are variable weft insertion structures, and the maximum lateral movement of the first ground comb and / or the second ground comb is greater than 3 needles.

[0011] Among them, the third ground comb structure is a chain stitch structure.

[0012] Among them, the first ground comb structure uses fully drawn yarn, the second ground comb structure uses fully drawn yarn, the third ground comb structure uses 1F fully drawn yarn, the fourth ground comb structure uses 1F fully drawn yarn, the first jacquard comb structure uses fully drawn yarn or drawn textured yarn, and the second jacquard comb structure uses fully drawn yarn or drawn textured yarn.

[0013] Among them, the first ground comb structure, the second ground comb structure, the third ground comb structure, the fourth ground comb structure, and the first jacquard comb structure use the same yarn material and are different from the yarn material used in the second jacquard comb structure.

[0019] To describe in detail the technical content, achieved objectives, and effects of the present utility model, the following is described in conjunction with the embodiments and in cooperation with the drawings.

[0020] A warp knitted fabric with a two-color grid structure includes a grid base layer and a first jacquard layer and / or a second jacquard layer woven on the grid base layer. Both the first jacquard layer and the second jacquard layer are composed of a first jacquard comb structure, a second jacquard comb structure, and a fourth ground comb structure;

[0021] The first jacquard layer includes a first color area and a second color area; in the first color area, the first jacquard comb structure changes to a chain stitch structure and a loop-forming structure, and the second jacquard comb structure changes to a weft insertion structure; in the second color area, the second jacquard comb structure changes to a chain stitch structure and a loop-forming structure, and the first jacquard comb structure changes to a weft insertion structure;

[0022] The second jacquard layer includes a third color area and a fourth color area; in the third color area, the first jacquard comb structure changes to a warp pile structure, and the second jacquard comb structure changes to a weft insertion structure; in the fourth color area, the second jacquard comb structure changes to a warp pile structure, and the first jacquard comb structure changes to a weft insertion structure.

[0023] As can be seen from the above description, the beneficial effects of the present utility model are as follows: The first jacquard layer and the second jacquard layer are obtained by changing the yarn and the process structure. The first jacquard layer only forms strip-shaped first color area and second color area at the grid edge. The second jacquard layer covers the grid base layer and obtains a third color area and a fourth color area in the form of color blocks. The warp knitted fabric with a two-color grid structure of the present utility model can achieve a pure two-color effect and has good air permeability and support performance.

[0024] Furthermore, the basic structures of the first jacquard comb structure and the second jacquard comb structure are warp plain structures.

[0025] Furthermore, the thickness of the first jacquard layer is greater than that of the second jacquard layer.

[0026] As can be seen from the above description, the second jacquard layer presents in the form of color blocks, has a thinner thickness and better air permeability.

[0027] Furthermore, the grid base layer is composed of a first ground comb structure, a second ground comb structure and a third ground comb structure.

[0028] As can be seen from the above description, the structure of the grid base layer can ensure that the shoe upper has good physical property indexes such as tensile force and dimensional stability.

[0029] Furthermore, the first ground comb structure and the second ground comb structure are changing weft insertion structures, and the maximum lateral displacement of the first ground comb and / or the second ground comb is greater than 3 needles.

[0030] As can be seen from the above description, the size of the grids in the grid base layer is determined by the changing weft insertion structure and by adjusting the lateral displacement of the first ground comb and / or the second ground comb.

[0031] Furthermore, the third ground comb structure is a chain stitch structure.

[0032] As can be seen from the above description, the chain stitch structure plays a bottoming role and is used to fix the weft insertion to form the grid.

[0033] Furthermore, the first ground comb structure uses full-drawn yarn, the second ground comb structure uses full-drawn yarn, the third ground comb structure uses 1F full-drawn yarn, the fourth ground comb structure uses 1F full-drawn yarn, the first jacquard comb structure uses full-drawn yarn or drawn textured yarn, and the second jacquard comb structure uses full-drawn yarn or drawn textured yarn.

[0034] As can be seen from the above description, the fully drawn yarn of 1F is a monofilament, and the color of the monofilament is transparent, which can endow the fabric with a certain degree of permeability. Under the same conditions, the fully drawn yarn is more permeable than the drawn textured yarn. The monofilament is transparent and has a certain strength. The mesh base layer obtained by using 2 fully drawn yarns + 1 monofilament has a comfortable hand feeling and a certain degree of support.

[0035] Furthermore, the yarn materials used in the first ground comb structure, the second ground comb structure, the third ground comb structure, the fourth ground comb structure, and the first jacquard comb structure are the same and different from the yarn material used in the second jacquard comb structure.

[0036] As can be seen from the above description, the yarn materials used in the first ground comb structure, the second ground comb structure, the third ground comb structure, the fourth ground comb structure, and the first jacquard comb structure can ensure that the color of the jacquard area formed by them is consistent with that of the base layer. In combination with the second jacquard comb structure with a different yarn material, a two-color effect is achieved after dyeing.
