AI Technical Summary

Technical Problem

Existing fabrics, while improving abrasion resistance, suffer from reduced breathability, affecting the comfort of clothing and making it difficult to meet the needs of outdoor sports and other scenarios.

Method used

The outer layer is made of nylon nonwoven fabric, and a polyacrylic acid coating is formed by modifying zinc acetate and a first finishing solution. This is combined with polyester textile fabric as the inner layer, and the modified zinc acetate is washed off by a second finishing solution to form a microporous structure, which improves breathability and abrasion resistance.

Benefits of technology

The preparation of a lightweight, microporous, breathable, and wear-resistant composite fabric has been achieved, maintaining the fabric's wear resistance and breathability while improving user comfort.

Abstract

The invention relates to the technical field of fabric preparation, in particular to a preparation method of a light and thin microporous breathable wear-resistant composite fabric, comprising the following steps: S1, mixing chinlon chips with modified zinc acetate, and performing melt spinning, lapping and hot rolling reinforcement to obtain an outer fabric; s2, performing melt spinning, spinning and weaving on polyester chips to obtain an inner-layer fabric; s3, spraying a first finishing liquid to the surface of the outer-layer fabric to obtain a finished outer-layer fabric; s4, coating the inner-layer fabric with a polyurethane hot melt adhesive, and performing hot pressing to obtain a pressed fabric; s5, soaking the laminated fabric in the second finishing liquid for multiple times to obtain the wear-resistant composite fabric. The wear resistance of the outer-layer fabric is improved through the first finishing liquid, the softness of the wear-resistant composite fabric is improved through the second finishing liquid, and modified zinc acetate is eluted, so that a microporous structure appears on the outer-layer fabric, and the air permeability and wear resistance of the wear-resistant composite fabric are ensured.
