Method for producing elastic spacer fabric through two-needle bar warp knitting machine

Abstract

The invention discloses a method for producing an elastic spacer fabric through a two-needle bar warp knitting machine. Guide bars in the warp knitting machine comprises the spacer yarn guiding guide bar, the ground guide bars and the elastic guide bars, wherein the spacer yarn guiding guide bar is arranged at the middle position, the ground guide bars are arranged on the two sides of the spacer yarn guiding guide bar, and the elastic guide bars are arranged on the outer sides of the ground guide bars. The distance between needle bars of the warp knitting machine is correspondingly set according to different applications of the spacer fabric to be produced. Yarns comprise the spacer yarns, the face yarns and the elastic yarns, and the face yarns and the elastic yarns with corresponding thread density are selected according to different surface structures of the spacer fabric. The spacer yarn guiding guide bar penetrates into the spacer yarns, the ground guide bars penetrate into the face yarns, and the elastic guide bars penetrate into the elastic yarns. The face yarns and the elastic yarns are matched to form the upper surface layer and the lower surface layer of the spacer fabric in a knitting mode, and the spacer yarns form the middle interlayer of the spacer fabric in a knitting mode. The spacer fabric produced through the method is good in elasticity, high in reset rate, compact, good in handfeel and high in comfort.

Description

Technical field: [0001] The invention belongs to the field of fabric weaving, in particular to a method for producing elastic spacer fabrics by a double needle bed warp knitting machine. Background technique: [0002] At present, many products for shoe materials, clothing, luggage and seats are made of warp-knitted spacer fabrics, because the warp-knitted spacer fabrics have good air and moisture permeability, light weight, good compression resistance, easy to wash and quick-drying During the process, it can provide a good microenvironment, effectively dissipate heat, ventilate and replenish fresh air, and improve the comfort during use, and the warp knitted spacer fabric also has the advantages of one-time molding and high production efficiency. [0003] There are many models for producing warp knitted spacer fabrics. The imported models include RD4N~RD7N, RD6DPLM~RD8DPLM and Racop D4~Racop D6, etc. Domestic models include GE298, GE2291B, GE6N, E2291 / 6 and E2291 / 7. These...

AI Technical Summary

Problems solved by technology

There are high motion coordination requirements between the two needle beds, between the knitting parts in the two needle beds, and between the two needle beds and the bar. The warp knitting machine is complex and has higher matching requirements, so it is difficult to produce a high gauge double needle bed warp knitting machine

Therefore, most spacer fabrics are produced with coarser gauges, and the fabric style is rough, making it difficult to produce denser spacer fabrics.

[0005] To sum up, the spacer fabric produced by the existing double-needle bed warp knitting machine is insufficient in elasticity, compact and compact, and has poor comfort, which cannot meet people's needs in the fields of clothing and decoration.
