Manufacturing method of elastic concave-convex warp knitted fabric and warp knitted fabric

Abstract

The invention provides a manufacturing method of an elastic concave-convex warp knitted fabric. The method comprises the steps of weaving preparation, guide bar configuration, knitting and the like. When a convex area of a concave-convex pattern is woven, GB4 is subjected to yarn laying and looping on a rear needle bed of a double-needle-bed warp knitting machine, and because low-elasticity yarn or non-elastic yarn serves as the GB4 for embroidering, the resilience amount of the woven yarn is relatively small or the woven yarn is not resilient. When a concave area of the concave-convex pattern is woven, GB3 is subjected to yarn laying and looping on the rear needle bed of the double-needle-bed warp knitting machine, the woven yarn is relatively large in resilience amount because spandex core-spun yarn serves as the GB3, and the yarn contracts to a bottom layer, so that a surface layer is sunken downward to the bottom layer, and the formed concave-convex structure has certain elasticity. Compared with a traditional technical scheme, the concave-convex warp knitted fabric can be directly woven without subsequent treatment, the process is simple, and the production cost is relatively low.

Description

technical field [0001] The invention relates to a fabric weaving method and fabric, in particular to a method for making an elastic concave-convex warp knitted fabric and the warp knitted fabric. Background technique [0002] The concave-convex warp knitted fabric is the warp knitted fabric with concave-convex jacquard effect on the surface. Because of its strong three-dimensional effect and good touch effect, it is widely used in various bags, shoes and clothing products. [0003] At present, this kind of concave-convex warp knitted fabric is usually difficult to obtain directly through weaving, but it needs to carry out specific treatment after the weaving is completed, such as the production method of a jacquard plush fabric disclosed in the Chinese invention patent application with the publication number CN101979741A. Knitting is performed on a double-needle-bar raschel machine equipped with five guide bars, equipped with a separate jacquard comb JB3.1 for loop formation...
