A kind of production method of polyester/cotton blended flame-retardant core-spun yarn

Abstract

The invention relates to a polyester / cotton blended flame-retardant core spun yarn and a production method thereof. The yarn is produced by blending 40 to 60 weight percent of polyester and 40 to 60 weight percent of cotton fibers. A process comprises the following steps: performing opening picking and carding on polyester to obtain polyester card slivers, performing blowing-carding, pre-drawing and combing on cotton to obtain cotton drawn slivers, performing drawing, roving and spinning on the polyester card slivers and the cotton drawn slivers to obtain polyester / cotton core yarns, and performing plasma pretreatment and yarn flame-retardant finishing to obtain flame-retardant polyester / cotton core yarns; blending polyester fibers and cotton fibers by a blowing-carding procedure, and performing pre-drawing, combing, drawing and roving to obtain polyester / cotton covering thick yarns; performing spinning on the obtained flame-retardant polyester / cotton core yarns and the obtained polyester / cotton covering thick yarns to obtain polyester / cotton blended core spun yarns in a core spinning manner, and performing plasma pretreatment and yarn flame-retardant finishing to obtain polyester / cotton blended flame-retardant core spun yarns. According to the polyester / cotton blended flame-retardant core spun yarn and the production method thereof, polyester and cotton are blended in the core spinning manner, and the core yarns and spun yarns are subjected to flame-retardant treatment, so that the spun yarns have high flame retardance.

Description

technical field [0001] The invention relates to the field of novel yarns, in particular to a polyester / cotton blended flame-retardant core-spun yarn and a production method thereof. Background technique [0002] Cotton fiber is currently the most widely used natural cellulose fiber. The fabric made of cotton fiber has good skin affinity, excellent hygroscopicity, strong alkali resistance, good heat insulation and heat resistance, and is easy to dye. It has poor wrinkle resistance and stretchability, is not resistant to strong acids, and is prone to mildew and flammability. The fabrics made of it also have a series of problems. Polyester fiber is an important variety of synthetic fibers. Polyester fiber has a series of excellent properties. The fabric made of it has high strength, good elasticity, excellent light resistance, easy washing and quick drying, but the hygroscopicity and air permeability of polyester fabric are poor. , poor dyeability, easy to pilling and easy to ...
