Embodiment Construction

[0010] A method for producing a warp-knitted biaxially felted reinforced fabric, comprising the steps of producing a single weft cloth, the step of pulling the single weft cloth into a bias weft cloth by a diagonal weft machine, and the step of producing a biaxially felted warp-knitted fabric,

[0011] 1. The steps of producing single weft fabric are woven from the spun yarn layer located in the 0° direction and the weft yarn layer located in the 90° direction through the binding yarn located in the 0° direction; the binding yarn is polyester low elastic yarn, and the binding yarn number is 55.5 -83.3dtex, the spun yarn layer in the 0° direction is glass fiber spun yarn, the maximum number of glass fiber spun yarn is 136dtex, the upper machine density is 3.0-5.0M / cm, and the weight per unit area is 400-600g / m 2 , the machine speed is 400-600r / min, and the binding yarn adopts braided chain structure;

[0012] 2. The step of pulling the single weft cloth into a diagonal weft clo...

Abstract

The invention belongs to the field of production of warp-knitted fabrics, and in particular relates to a method for producing a warp-knitted biaxial felted reinforced fabric. The method for producing the warp-knitted biaxial felted reinforced fabric comprises the steps of producing single weft cloth, drawing the single weft cloth into skewing weft cloth through a skewing weft knitting machine, and producing a biaxial felted warp-knitted fabric. The method has the advantages that the weft direction of the biaxial felted reinforced fabric knitted by the process is unlikely to extend to two sides; the structural stability of the biaxial felted reinforced fabric is improved; a special structural design requirement on a biaxial felted fabric caused by a customer is met; fabrics with different breadths can be produced; the warp-knitted biaxial felted reinforced fabric has the characteristics of low extension rate, high strength and high resin permeability.

Description

technical field [0001] The invention belongs to the production field of warp-knitted fabrics, in particular to a production method of warp-knitted biaxial felt reinforced fabrics. Background technique [0002] The conventional method of weaving biaxial felt reinforced fabric is to bundle and weave it by laying reinforcing fibers in the direction of 0°, laying the reinforcing fibers in the direction of ±60° or ±45°, and weaving them according to the weaving method of warp flat or variable warp flat into reinforced fabrics. The biaxial felt-reinforced fabric woven by the conventional method tends to expand to both sides in the weft direction, has poor structural stability, and has a single fabric width, which cannot meet the special requirements of customers for fabric performance. Contents of the invention [0003] The purpose of the present invention is to propose a production method for a biaxially reinforced fabric with felt, which can pass through the upper and lower ...
