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 a composite yarn made of nylon filaments twisted with viscose staple yarn and a preparation method thereof, belonging to the technical field of textiles. The composite yarn of nylon filament twisted viscose staple yarn of the present invention comprises 60-70% viscose staple fiber and 30-40% nylon filament; nylon filament twisted viscose staple fiber of the present invention The weight per hundred meters of the composite yarn of the yarn is 3.5-4g; the breaking strength of the single yarn is 900-1000cN; the twist is 530-630. The present invention combines the viscose spun yarns and nylon filaments that are not easy to be compounded together by means of air-flow mesh joint strands, and the elastic properties of the nylon filaments are stretched by the yarn guide and the tension control device, and the yarn is reassembled at the same time as the network. To endow the composite yarn with elastic properties. The composite yarn material of the nylon filament twisted viscose staple fiber yarn in the present invention has clear bead patterns, and the elasticity and drape feeling are perfectly matched.

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 repeated deformation. 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, ...
