Title:
DOUBLE-LAYER WARP-KNITTED SPACER FABRIC AND WARP KNITTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/042869
Kind Code:
A1
Abstract:
The present invention relates to the technical fields of warp-knitted spacer fabrics and textile equipment, and disclosed therein are a double-layer warp-knitted spacer fabric and a warp knitting machine. The double-layer warp-knitted spacer fabric described in the present invention comprises: a first double-fabric layer and a second double-fabric layer; the first double-fabric layer and the second double-fabric layer are sewn together by means of a sewing layer to form the double-layer warp-knitted spacer fabric, wherein the difference between the elastic coefficient of the first double-fabric layer and the elastic coefficient of the second double-fabric layer meets a first preset requirement. According to the present solution, the difference between the elastic coefficient of the first double-fabric layer and the elastic coefficient of the second double-fabric layer meets a first preset requirement, thus the first double-fabric layer and the second double-fabric layer have different elastic potential energy, i.e., compression performance. Therefore, two surfaces of the double-layer warp-knitted spacer fabric that is formed after the first double-fabric layer and the second double-fabric layer are sewn by means of the sewing layer have different anti-compression performance.
