Problems solved by technology

Especially when the blending components are chemical fibers such as polyester or nylon that do not have flame retardant function, the flame retardant performance of the blended fabric is greatly affected
The flame retardant problems such as droplet and shrinkage of polyester / cotton blended flame retardant fabrics with a high proportion are still difficult to solve

Embodiment Construction

[0017] With 75D high-strength polyester filament as the core and combed cotton as the covering layer, the ratio is: polyester / cotton = 35 / 65, spinning cotton-polyester core-spun yarn, and the yarn count is 22s. The yarn is usually The weaving process is to weave the fabric, the fabric size is 108×55, after desizing, singeing, and scouring pre-treatment, the core-spun yarn fabric is obtained, and the weight per unit area is 150g / m 2 , using the Proban flame-retardant post-finishing process of cotton fabrics to prepare flame-retardant core-spun yarn fabrics. Its performance index is: weight per unit area 165g / m 2 ;Flame retardant performance: the continuous burning and smoldering in the warp and weft direction are both 0s, the damage length is not more than 100mm, carbonization, no droplet, no shrinkage, and the single tongue tear strength in the warp and weft direction is not less than 41N; the tensile breaking strength in the warp direction is not less than 900N , The weft di...

Abstract

The invention discloses a flame-retardant covering yarn fabric and application thereof. The product is made from covering yarns, wherein the covering yarns are subjected to the processing of flame-retardant after finishing; the core yarns of the covering yarns are polyester, nylon, spandex, vinylon, polyethylene or composite yarns thereof; and the cladding material of the covering yarns are cotton fibers, viscose fibers or composite fiber materials thereof. The flame-retardant covering yarn fabric can be applied to the manufacturing of protective clothing, military clothing or military coverlets. The flame-retardant covering yarn fabric provided by the invention can keep higher physical mechanical strength and has a flame-retardant effect.

Description

technical field [0001] The invention relates to a flame-retardant core-spun yarn fabric and its application. Background technique [0002] For some special labor protection clothing and military functional clothing, protective fabrics with high mechanical strength and good wearing and flame-retardant functions are becoming more and more important. [0003] Cellulose fiber fabrics, such as cotton or viscose fabrics, are cheap, rich in sources, have a hygroscopicity similar to that of human skin, and feel comfortable. The flame-retardant finishing technology of cotton or viscose fabrics is mature and has good flame-retardant properties. , especially when burning, it does not shrink, does not melt, and has no melting holes. After high-temperature carbonization, it still retains the original skeleton, which can play a role in heat insulation protection. However, after chemical flame-retardant finishing of cotton or viscose fabrics, its There is a great loss of strength, reachin...
