High-strength flame-retardant jean and production process and uses thereof

Abstract

The invention discloses high-strength flame-retardant jean and a production process and uses thereof. The high-strength flame-retardant jean comprises wefts of aramid fiber, and the aramid fiber has the good properties such as superhigh strength, high modulus, high temperature resistance, acid-base resistance, light weight, insulation, ageing resistance and long life. Through the use of the aramid fiber for the wefts of the jean, the jean can be higher in strength and wear resistance, the jean can be flame retardant, and the application range of the jean is widened. Warp-wise breaking strength of the high-strength flame-retardant jean is 1.4 times as high as that in common jean, and weft-wise breaking strength is up to 7 times as high as that in common jean; warp-wise tearing strength of the high-strength flame-retardant jean is 1.5 times as high as that of the common jean, and the weft-wise tearing strength is 4 times as high as that of the common jean; the high-strength flame-retardant jean is twice as wear resistant as the common jean; accordingly, the high-strength flame-retardant jean is available for both casual clothes and some industrial fields, and is also available for protective work suits used in places of electrowelding, automobile racing and the like. The jean can be still fashionable in various fields.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to high-strength flame-retardant denim and its production process and application. Background technique [0002] Along with the increase of denim style, people are also more and more higher to the requirement of denim, although textile technology improves constantly, still there are some defectives that cannot satisfy demand. At present, most of the warp and weft materials of denim on the market are some ordinary materials, such as cotton, or some relatively cheap polyester fibers, spandex, etc. are added. Although the cost is reduced and the elasticity is increased, the strength of denim is still inferior. enhanced. In particular, some denim garments need to make special hole effects, which have higher requirements on the strength of the weft yarns of denim. Ordinary yarns are not strong enough, which can easily cause the fabric at the hole to rot, thereby expanding the hole and ...

AI Technical Summary

Problems solved by technology

At present, most of the warp and weft materials of denim on the market are some ordinary materials, such as cotton, or some relatively cheap polyester fibers, spandex, etc. are added. Although the cost is reduced and the elasticity is increased, the strength of denim is still inferior. enhance

In particular, some denim garments need to make special hole effects, which have higher requirements on the strength of the weft yarns of denim. Ordinary yarns are not strong enough, which can easily cause the fabric at the hole to rot, thereby expanding the hole and failing to achieve the desired effect. specific decorative effect

Moreover, the denim fabric woven with ordinary yarns has limited strength and no flame-retardant function, so it can only be used for casual clothing, and its application range is relatively narrow.
