Embodiment Construction

[0011] The braiding method of warp-knitted biaxial reinforcement fabric, it comprises the steps,

[0012] a. The laying of reinforced fibers in the direction of 0°, place the bobbins of reinforced fibers on the creel, and the reinforced fibers pass through the tension control device to each splitting device to the warp let-off roller, and then through the splitting device and finally introduced to the interlining warp In the device, the laying of reinforcing fibers in the 0° direction is completed;

[0013] b. For the laying of reinforced fibers in the 90° direction, the bobbin of reinforced fibers is placed on the creel, through the tension control device to each yarn dividing device to the weft laying device of the biaxial warp knitting machine, the weft laying The device is used to complete the lay-up of reinforcing fibers in the 90° direction;

[0014] c. Feed the reinforcement fibers in the 0° direction and the reinforcement fibers in the 90° direction to the knitting me...

Abstract

The invention belongs to the field of methods for knitting warp-knitted fabrics and in particular relates to a method for knitting a warp-knitted biaxial reinforced fabric. The method comprises the following steps: laying reinforced fibers in directions of 0 degree and 90 degrees, feeding the reinforced fibers in the directions of 0 degree and 90 degrees into a knitting mechanism of a biaxial warp-knitting machine, binding, and knitting the reinforced fibers into the biaxial reinforced fabric. The method has the advantages that the biaxial reinforced fabric produced by the method is not easily ravelled in a warp direction when being cut, the structural stability of a uniaxial reinforced fabric is improved, the requirements of customers on avoidance of the ravelling of the warp yarns of the biaxial fabric in a cutting process are met, the product quality of the biaxial reinforced fabric is greatly improved, and the fabric has the characteristics of low elongation rate, high strength, good toughness and the like.

Description

technical field [0001] The invention belongs to the field of warp-knitted fabric weaving methods, in particular to a weaving method for warp-knitted biaxially reinforced fabrics. Background technique [0002] The conventional method for weaving biaxially reinforced fabrics is to bundle and weave them into reinforced fabrics by laying reinforcing fibers in the 0° direction and laying the reinforcing fibers in the 90° direction according to warp flat or variable warp flat weaving methods. When the biaxially reinforced fabric woven by the conventional method is cut, the warp yarns are easy to fall apart, and the structural stability is poor, which cannot meet the special requirements of customers for the shear performance of the fabric. Contents of the invention [0003] The object of the present invention is to propose a weaving method for biaxially reinforced fabrics in view of the fact that the above-mentioned conventional biaxially reinforced fabric weaving methods cannot...
