Problems solved by technology

[0007] The present invention aims to solve the problems of high production cost, complicated production steps and thick bead yarn formed in the prior art. Its preparation method, in the preparation of the composite yarn of nylon filaments twisted with viscose spun yarns, the viscose staple fibers and nylon filaments which are not easy to be compounded are joined by airflow net joint strands Make it composite together, make the elastic properties of nylon filaments pass through the drafting of the yarn guide and tension control device, and give the composite yarns elastic properties again at the same time as the network

Abstract

The invention discloses polyamide yarn and viscose staple yarn twisted composite yarns and a preparation method thereof, belonging to the technical field of textile. The polyamide yarn and viscose staple yarn twisted composite yarns are prepared from 60-70% of viscose staple fibers and 30-40% of polyamide yarns; the mass of per hundred meters of the polyamide yarn and viscose staple yarn twisted composite yarns is 3.5-4g; the single yarn breaking strength is 900-1000cN, and degree of twist is 530-630. The viscose staple yarns and the polyamide yarns, which are hard to compound together, are compounded together by means of air-flow net join strands; the elastic property of the polyamide yarns is drawn by means of a yarn guide and tension control device, so that the composite yarns are endowed with the elastic property again while being woven. The polyamide yarn and viscose staple yarn twisted composite yarns provided by the invention is clear in bead patterns, and has perfectly matchedelasticity and drape feeling.

Description

technical field [0001] The invention relates to a composite yarn made of nylon filaments twisted with viscose staple yarn and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] The fabric woven with viscose staple fiber as knitting yarn has the characteristics of excellent hygroscopicity and good drapability, but due to the low wet strength of viscose staple fiber itself, it is easy to cause the fabric to deform and wrinkle. Nylon filament fabric has low moisture absorption rate, low initial modulus, easy deformation during use, excellent resilience, and good resistance to multiple deformations. The fabric produced by pure nylon filament has good strength and elasticity, fluffy, but relatively sticky When the staple fiber has good moisture absorption, it has poor wearability. How to make full use of the high hygroscopicity, bright color, smooth hand feeling of rayon and the fluffy and good elongation of nylon filaments,...
