Warp-knitted insulation fabric and production method and application thereof

Abstract

The invention discloses a warp-knitted insulation fabric and a production method and application of the wrap-knitted insulation fabric. The wrap-knitted insulation fabric is a plain-cloth warp-knitted fabric of a three-layer structure; 15 to 50 wt% by parts of spun polyester yarn structures transversely move in a distance not greater than two stitch length to form an upper surface layer and a lower surface layer; 85 to 50 wt% by parts of viscose yarn structures of which the break strength is more than 1.8cN / dtex transversely move in a distance not greater than three stitch length to form a medium layer. The fabric has the moisture-absorption and heat-generation performances, and the temperature can be raised to be 24 to 26 DEG C; in addition, the fabric touches soft and is high in air permeability; the fabric can be used for manufacturing sports wears, linings or trousers.

Description

technical field [0001] The invention relates to a warp-knitted thermal insulation fabric and its production method and application. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the comfort and thermal insulation performance of clothing. At present, thermal insulation fabrics on the market are generally realized by cotton fibers, viscose fibers or chemical fiber blended fabrics. For cotton fiber fabrics, because the cotton fiber has natural curls, the cross-section has a cavity, and the heat retention is better, it will be more comfortable after wearing it at first, but after a period of human metabolism, it will feel more sticky, especially easier to sweat For those who live, the moisture produced is more difficult to volatilize, especially in winter, the moisture that cannot volatilize will give people a feeling of clamminess, and cotton fiber fabrics have the disadvantages of being easy to wrinkle, ...

AI Technical Summary

Problems solved by technology

For cotton fiber fabrics, because the cotton fiber has natural curls, the cross-section has a cavity, and the heat retention is better, it will be more comfortable after wearing it at first, but after a period of human metabolism, it will feel more sticky, especially easier to sweat For those who live, the moisture produced is more difficult to volatilize, especially in winter, the moisture that cannot volatilize will give people a feeling of clamminess, and cotton fiber fabrics have the disadvantages of being easy to wrinkle, shrink, and not crisp in appearance; for viscose fiber In terms of fabrics, the market is mainly divided into woven and circular knitting. Although it has good thermal insulation performance, woven fabrics have problems such as poor air permeability and rough handle, while circular knitting has relatively high elasticity, easy to fall apart, and forming Poor performance and other problems; for chemical fiber blended fabrics, although the price is cheap, it is easy to generate static electricity, which will absorb a lot of dust and dander

[0003] Chinese patent document CN101979736A discloses a composite yarn formed by blending polyester fiber and viscose fiber. Although the antistatic property and comfort of the fabric produced by using this yarn are improved to a certain extent, because the blended yarn is made of short Formed by fibers, the yarn strength is low, the hairiness is high, and the weaving performance is poor. It is not suitable for warp knitted fabrics with good loosening resistance and formability, and cannot meet the needs of customers with higher quality requirements.
