AI Technical Summary

Technical Problem

Existing anti-permeability fabrics, while maintaining lightness and breathability, have low anti-permeability effects and a generally stiff texture. Their three-dimensional structure is difficult to maintain stability and fluffiness during long-term washing and wearing.

Method used

The structure adopts a first braided layer and a second braided layer. The second braided layer is made of core-spun yarn woven into the first braided layer through a braiding process. The edges of the core-spun yarn are cut and high-temperature set to form a three-dimensional plush structure. The core-spun yarn is made of high-melting-point yarn and glass fiber yarn twisted together. The low-melting-point yarn shrinks to form a spiral shape during high-temperature setting, which enhances the stability and impermeability of the three-dimensional structure.

Benefits of technology

During long-term wear and washing, the three-dimensional waterproof fabric maintains its softness and drape while improving its waterproofness and three-dimensional shape, avoiding the problem of the fabric's overall texture being too stiff and maintaining a good three-dimensional shape.

Abstract

The invention relates to the field of textile fabrics, and discloses a three-dimensional anti-transparent fabric and a preparation process thereof. The three-dimensional anti-transparent fabric comprises a first weaving layer and a plurality of second weaving layers, the second weaving layers are manufactured by weaving covering yarns on the first weaving layer through a weaving process, and the edges of the second weaving layers are of a three-dimensional plush structure formed by cutting and high-temperature shaping of the covering yarns. Core yarn of the covering yarn is formed by twisting a plurality of high-melting-point yarn and at least one glass fiber yarn, and wrap yarn is low-melting-point yarn. According to the three-dimensional anti-transparent fabric, after the covering yarn on the edge of the second woven layer is cut and subjected to high-temperature setting, the covering yarn shrinks to form a spiral shape, a three-dimensional plush structure is formed on the edge of the second woven layer, and under the cooperative supporting effect of the covering yarn and the shrinkage wrap yarn, the three-dimensional anti-transparent fabric with the stable three-dimensional structure is formed; in the long-term wearing and water washing process, the fabric is not prone to deformation, and good softness, three-dimensional performance and anti-permeability are kept.
