Problems solved by technology

[0003] (1) Foaming and wrinkling: in the three-layer structure, in order to achieve the effect of two-color or multi-color dyeing after fabric dyeing, at least two kinds of weaving materials must be used, such as nylon, polyester, cationic, etc., and the dryness of different weaving materials The thermal shrinkage rate is different, and each kind of weaving raw material is divided into categories such as non-elastic, low-elastic, medium-elastic, high-elastic, etc., and the elastic shrinkage rates are also different; this leads to the three-layer structure Double jacquard mesh is easy to foam and wrinkle;
[0004] (2) Irregular through holes: In the three-layer structure, the front and back of the gray cloth are prone to offset and misalignment during the weaving production process, which leads to the problem of uneven through holes in the mesh formed by weaving on the fabric, and the through hole rate is average. only reach around 50%;
[0005] (3) Exposed line in the hole: In the three-layer structure, during the weaving production process, the front side of the gray cloth and the back side of the gray cloth are prone to offset and dislocation, resulting in the connection line of the middle connecting layer being exposed in the mesh, and this exposure relationship is due to The difference in offset and dislocation rate between the front and back of the gray cloth presents an irregular and disorderly distribution, which seriously reduces the beauty of the woven fabric and reduces the qualified rate of the product;
[0006] (4) Low physical properties and low supporting force: the middle connecting layer is formed by knitting the Jacquard bar JB1 or Jacquard bar JB2 on the double needle bed double Jacquard warp knitting machine, and the middle connecting layer is knitted in the horizontal direction. The reduction of connecting lines in the horizontal weaving plane leads to low physical properties and low supporting force of the woven double jacquard jacquard mesh. The tear strength, tensile breaking strength and breaking strength of the fabric often fall short of those of some international shoe-making brands. Requirements are often lowered fabric standards through negotiation with customers, which seriously reduces the company's income;

Abstract

The invention discloses a knitting method of a double-jacquard net cloth. The knitting method comprises the steps of firstly defining the basic structure of a guide bar, and then performing double-jacquard net cloth knitting, wherein double-jacquard net cloth knitting comprises the steps of conducting working of guide bar yarn laying by a ground guide bar GB1 in coordination with a jacquard pattern guide bar JB1 at a leading bar, and forming the jacquard pattern effect of the obverse side of a grey cloth through knitting; forming a base fabric of the grey cloth through joint knitting of a ground guide bar GB6 and a jacquard pattern guide bar JB2, and forming the V-point jacquard effect of the obverse side of the grey cloth through knitting of jacquard pattern guide bar JB2; forming an obverse and reverse face connecting line through knitting of a ground guide bar GB5, under the knitting effect of the ground guide bar GB5, integrally knitting and connecting the obverse and reverse faces of the grey cloth into one, and knitting and forming the double-jacquard net cloth. According to the knitting method of the double-jacquard net cloth, during knitting, the obverse and reverse faces of the grey cloth are knitted and connected into one closely without gap, the problems of blistering and wrinkling, irregular through holes, exposed stitching in the holes, low physical property, low support power and the like are solved, and the knitting production quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mesh production, in particular to a weaving method for a double jacquard mesh that can effectively weave and connect the gray cloth front and the gray cloth back tightly without gaps. Background technique [0002] In the existing mesh production technology, the double jacquard mesh is generally woven by a double needle bed double jacquard warp knitting machine, and the double jacquard mesh made by weaving is generally composed of the gray cloth front and middle connecting layer. It is composed of three layers on the reverse side of the gray cloth. The fabric actually has a three-layer structure. The double jacquard mesh made of weaving has the following defects: [0003] (1) Foaming and wrinkling: in the three-layer structure, in order to achieve the effect of two-color or multi-color dyeing after fabric dyeing, at least two kinds of weaving materials must be used, such as nylon, polyester, cationic, etc....
