Description

A method for producing elastic spacer fabrics on a double-needle bed warp knitting machine

Technical field:

The invention belongs to the field of fabric weaving, in particular to a method for producing elastic spacer fabrics on a double-needle bed warp knitting machine.

Background technique:

At present, many products for shoe materials, clothing, luggage and seats are made of warp-knitted spacer fabrics, because warp-knitted spacer fabrics have good air and moisture permeability, light weight, good compression resistance, and are easy to wash and dry quickly. During the process, it can provide a good micro-environment, 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.

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 models are equipped with 1 to 3 spacer yarn guide combs, and the others are ground combs. The spacer yarn guide combs usually penetrate monofilaments such as polyester, nylon, and polypropylene, and the ground combs usually penetrate polyester, nylon, polypropylene, etc. Chemical fiber filaments are woven. Since the double-needle bed machines are not equipped with spandex bars, the warp-knitted spacer fabrics produced by these machines are insufficient in elasticity, small in deformation capacity, and not compact in structure, and their comfort and aesthetics are affected during use.

The most commonly used spacer fabric warp knitting machine gauge is E24, that is, 24 knitting needles per inch. In order to increase the fineness and compactness of the spacer fabric, the gauge of the double-needle bed spacer fabric warp knitting machine can be increased, and the current highest gauge is E32. The double-needle bed spacer fabric warp knitting machine has two needle beds, two weaving needles, two sets of guide needles, two sets of sinkers and two sets of knockout plates. 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 coordination requirements, so it is difficult to produce a high gauge double needle bed warp knitting machine. Therefore, most spacer fabrics are produced in coarse gauges, and the fabric style is rough, making it difficult to produce denser spacer fabrics.

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, and cannot meet people's needs in the fields of clothing and decoration.
