Embodiment Construction

[0015] The production method of triaxial warp knitted fabric, step comprises three steps,

[0016] In the first step, the uniaxial warp knitted fabric is produced by warping, upper shaft and weaving on the common biaxial warp knitting machine, and the uniaxial warp knitted fabric is a single weft cloth,

[0017] Warp the weft yarn and binding yarn first, lay the weft yarn layer in the 90° direction, and then weave through the binding yarn in the 0° direction. 145~155g / m 2 , the machine speed of the warp knitting machine is 650-700r / min, and the binding yarn adopts a knitting chain structure;

[0018] In the second step, the single weft is woven into oblique weft cloth,

[0019] Place two sets of single weft fabrics on the roll unwinding device behind the multiaxial warp knitting machine, and then pull them into two sets of diagonal weft fabrics through the oblique weft machine, and the weft angle of one set of oblique weft fabrics is + 45° inclined, the weft angle of the ot...

Abstract

The invention belongs to the field of a processing method of woven fabric and particularly relates to a method for producing triaxial warp knitted fabric. The method comprises the following steps: producing mono-axial warp knitted fabric by warping, winding and weaving on a common double-axial warp knitting machine; drawing single-weft fabric into oblique-weft fabric; and producing the triaxial warp knitted fabric from the oblique-weft fabric on a conventional multi-axial warp knitting machine. Compared with the prior art, the invention has the advantages that the cost for producing a unit finished gray fabric is low, the width of the gray fabric of the triaxial warp knitted fabric can be flexibly controlled and the requirements of customers on different widths of the triaxial warp knitted fabric are well met.

Description

technical field [0001] The invention belongs to the field of production methods of textile fabrics, in particular to the production methods of triaxial warp knitted fabrics. Background technique [0002] The warp-knitted tri-axial fabric is produced in one step on the conventional multi-axial warp knitting machine. Due to the expensive equipment, the unit finished gray fabric consumes more funds, the cost is higher, and the width is limited. Generally, only 2.54m can be produced. and a width of 1.27m. Contents of the invention [0003] The present invention aims at the shortcomings of the high cost and limited width of the triaxial fabric produced by the one-step method in the above-mentioned technology, and proposes a production method of the triaxial warp knitted fabric produced by the three-step method, which has the equipment cost of Low cost, less capital consumed per unit of finished gray fabric, saving production cost, and the width of the produced fabric is not li...
