Problems solved by technology

Existing multi-layer non-woven fabrics, its structure is mainly multi-layer single non-woven fabrics, and the binder that is arranged between adjacent single non-woven fabrics, but the multi-layer non-woven fabrics of this pattern, when using at least There are the following disadvantages: first, the multi-layer single non-woven fabric is only connected by adhesive, so the connection strength is not enough; second, the non-woven fabric is hot-pressed after the short fibers are evenly spread out, so Lack of neatly styled lines, patterns
[0005] However, the warp knitting process in this invention patent has the problem that the strength in the warp direction is not significantly improved after warp knitting, and the warp knitting thread is easy to fall.

Abstract

The invention belongs to the technical field of woven cloth, in particular to a warp knitting method for producing composite fiber cloth. In the present invention, an inner adhesive is arranged between the main non-woven fabric and the auxiliary non-woven fabric, and then the warp-knitted thread is used to weave and fix, and finally the first cover adhesive, the second cover adhesive and the thread ends are coated. The method of binder can achieve the effect of higher structural strength and richer thread pattern of the composite non-woven fabric with warp-knitted thread structure. The invention has high stability of the W-shaped weaving structure of the warp-knitted threads on the composite non-woven fabric, and the warp-knitted threads themselves are not easy to loosen. The thread ends are not easy to fall off and the covering effect is good, the double-sided cover structure has high stability, the entire composite fiber cloth has high integrity, and different types of fibers can be flexibly selected for compounding.

Description

technical field [0001] The invention belongs to the technical field of woven cloth, in particular to a warp knitting method for producing composite fiber cloth. Background technique [0002] Composite fiber cloth refers to a type of cloth that contains a variety of different fibers, such as blended cloth and multi-layer non-woven cloth. Existing multi-layer non-woven fabrics, its structure is mainly multi-layer single non-woven fabrics, and the binder that is arranged between adjacent single non-woven fabrics, but the multi-layer non-woven fabrics of this pattern, when using at least There are the following disadvantages: first, the multi-layer single non-woven fabric is only connected by adhesive, so the connection strength is not enough; second, the non-woven fabric is hot-pressed after the short fibers are evenly spread out, so Lack of neatly styled lines, patterns. [0003] So to sum up, there is an urgent need in the market for a new type of composite fiber cloth with...
