Forming method of compression-resistant structure warp knitting interval fabric

Abstract

Disclosed is a formation method of a warp-knitted spacer fabric with improved compression resistance capability through morphological stability of interval yarns. Said method is performed at a double needle bar warp machine and comprises steps as follows: utilizing knitting needle combers corresponding to front and back needle bar to feed yarn to form plaiting chain structure tissue at each needle bar; utilizing combers in middle of the warp machine to front and back connect and weave yarn fed, wherein plaiting chains of adjacent needle bars are connected with a certain interval distance, to form a plurality of unattached trapezia band shaped tissue with a certain width; selectively breadthwise connecting knitting needle of each needle bar, with weft insertion or loop formation modes, corresponding to front and back needle bar knitting needle combers, and weaving breadthwise unattached band shaped plaiting chains to a mesh structure tissue, wherein connection parts of every two plaiting chain form the cylinder body of the mesh tissue, and the unconnected parts are pulled into holes of the mesh tissue, in a word, connecting a plurality of trapezia band shaped tissue with a certain width into a space type mesh warp-knitted fabric of a whole integral structure, with a thickness; with regard to landscape orientation connecting comber, synthetically considering two needle bars cooperating with each other to get through each other to ensure that the mesh weaven by front and back needle bars is kept in a stagger state along landscape fabric orientation, and the space yarns connecting plaiting chains weaven by front and back needle bar knitting needles are made form continuous 'W' shapes at cross sections of fabrics. Therefore, the purpose to improve compression resistance capability and morphological stability of interval yarns are achieved.

Description

Technical field [0001] The invention relates to a method for forming a warp-knitted spacer fabric, in particular to a method for forming a warp-knitted spacer fabric with a compression-resistant structure, and belongs to the field of knitted industrial fabrics. Background technique [0002] At present, the existing process design method makes the warp-knitted spacer fabric made in the structural form. Generally, the spacer yarns in the middle are basically arranged in parallel to each other, which makes the overall spacer fabric have a different parallelogram shape. Stability, especially when the thickness of the spacer is large, it is easy to "get down" under pressure, so it is difficult to make the product form a larger spacer thickness or have a greater compression resistance, which affects the use of warp-knitted spacer fabrics. Contents of the invention [0003] In order to overcome the deficiencies of the existing warp-knitted spacer fabrics in structural form, space...

[0002] At present, the existing process design method makes the warp-knitted spacer fabric made in the structural form. Generally, the spacer yarns in the middle are basically arranged in parallel to each other, which makes the overall spacer fabric have a different parallelogram shape. Stability, especially when the thickness of the spacer is large, it is easy to "get down" under pressure. Therefore, it is difficult to make the product form a larger spacer thickness or have a greater compression resistance, which affects the use of warp-knitted spacer fabrics.
