AI Technical Summary

Technical Problem

The prior art is difficult to achieve rapid moisture-absorbing and dimensional stability of denim fabrics at the same time, and commonly used hydrophilic finishing agents may lead to skin allergies and short-term hygroscopicity.

Method used

A novel filament structure yarn is used, which is made of coaxial spinning, including cellulose fibers in the outer layer, low melting point chemical fibers in the intermediate layer, and high initial modulus chemical fibers in the inner layer. This structure forms a water conduction channel during the post-organization process, improving moisture absorption and moisture conduction properties while maintaining the dimensional stability of the fabric.

Benefits of technology

The high moisture absorption and moisture conductivity of the yarn are achieved, avoiding the problems of high shrinkage rate and unstable size of the fabric, while improving wear comfort and anti-static properties.

Abstract

The invention discloses a novel filament structure yarn and fabric, and belongs to the field of textile, the yarn comprises a three-layer structure formed by coaxial spinning, the three-layer structure sequentially comprises an inner layer, a middle layer and an outer layer from inside to outside, the outer layer is made of cellulosic fibers, the inner layer and the middle layer are made of chemical fibers, and the melting point of the middle layer is lower than that of the inner layer and that of the outer layer; the initial modulus of the inner layer is larger than that of the middle layer and that of the outer layer, and the elastic elongation of the middle layer is larger than that of the outer layer. The middle layer is melted and collapsed in the process of after-treatment, a water guide channel is formed between the outer layer and the inner layer, cellulose fibers of the outer layer are high in hygroscopicity and comfortable in touch feeling, water absorbed by the outer layer can be conveyed through the channel formed after the middle layer collapses, the yarn has the hygroscopicity and the moisture conductivity, the initial modulus of the inner layer is high, shape keeping of the yarn is facilitated, and the yarn is more attractive in appearance. Large shrinkage of the fabric caused by high shrinkage rate of the cellulose fibers and collapse of the middle layer is avoided, and the prepared fabric is small in shrinkage rate and stable in size.
