Preparation method of knitted nonwoven joint cloth

Abstract

The invention relates to a preparation method of knitted nonwoven joint cloth, and belongs to the technical field of textiles. The preparation method is carried out on a nonwoven needling machine, andincludes the two steps of needling strengthening and knitted stitch forming; on one hand, a yarn guide device and a yarn threading device are added, on the other hand, first-row needles on a needle plate in the moving direction of a fiber web is changed into latch needles. When felting needles and the latch needles on the needle plate move together, the felting needles can complete nonwoven forming, the latch needles hook and take yarn which is guided out by the yarn guide device into the yarn threading device, and stitch knitting can be completed. Movements of the felting needles and the latch needles are combined together to omit an additional knitted stitch forming device, so that nonwoven forming and knitted forming are combined together to be completed, the time is reduced, the process is simplified, and finally, not only can the knitted nonwoven effect be formed, but also the strength of the joint cloth can be improved. The preparation method is ingenious in design, convenient to operate, unique in product effect and suitable for application and promotion.

Description

technical field [0001] The invention relates to a method for preparing a knitted nonwoven combined fabric, which belongs to the technical field of textiles. Background technique [0002] The combined technology of knitting and nonwovens is widely used in production and life, mainly divided into web-type stitch-bonded non-woven materials and yarn-type stitch-bonded non-woven materials, as well as composite materials of knitted fabrics and non-woven fabrics. Although the fiber mesh type stitch-bonded nonwoven material also directly reinforces the fiber mesh, the strength of the cloth is not enough due to the reinforcement produced by fiber looping alone, and there are a large number of exposed fibers. Although yarn-type stitch-bonded nonwoven materials use additional yarns to form loops to strengthen the fiber web, the current loop-forming effect is similar to that of warp knitting, and the fiber web reinforcement is not very strong. Although the composite material of knitted...

AI Technical Summary

Problems solved by technology

Although the composite material of knitted fabric and nonwoven fabric contains two kinds of cloth surface effects, the composite process is complicated and easy to separate

There is no report on the method that can not only produce knitted and non-woven cloth surface effects, but also optimize the process and increase the strength of the cloth surface
