Viscose imitation silk yarn production device and spinning method thereof

Abstract

The invention discloses a viscose imitation silk yarn production device and a spinning method thereof. The viscose roving is drawn to obtain fiber strands, and then the twist generated by a winding system is twisted at the initial twisting point to form an initial viscose spun yarn. An annular twisting belt is set at the front of the front roller. The viscose spun yarn passes between the front and rear side belts of the twisting belt at the initial twisting point. The motor drives the twisting belt to rotate and then twists the passed viscose spun yarn. Function, the twisting degree is transmitted upwards and downwards respectively, and the upper transmission performs pre-reverse twisting on the fiber strands opposite to the twisting direction, so that the initial twisting point is moved up, and the first fiber bundle is obtained to improve the initial twisting section strength, reduce end breakage, and the lower transmission produces pre-positive twist on the spinning section, which greatly enhances the twist of the spinning section. After the first fiber bundle passes through the twisting belt, its own pre-reverse twist immediately matches the spinning The pre-forward twisting twist of the yarn segment is offset, and then immediately re-twisted by the twisting twist to obtain the final viscose spun yarn with high strength and less hairiness.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a new ring spinning method, in particular to a viscose imitation silk yarn production device and a spinning method thereof. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements are put forward for the development of textile raw materials and textile technology. Among them, high-quality, high-performance textiles and clean production and processing have become the main development direction of the modern textile industry and an effective way to improve product grades and added value. With the improvement of modern living standards and the acceleration of the pace of work, the high shape retention and easy care of textiles have become important attribute...

AI Technical Summary

Problems solved by technology

However, there are still many problems in shape retention of fabrics made of different fiber materials. For example, cotton fabrics are easy to wrinkle when worn, poor flatness after washing and drying, and need to be ironed; Chemical fiber fabrics are easy to arch and keep shape when worn

Many practical problems such as insufficient shape retention, unstable shape retention effect, and difficulty in controlling the environmental protection index of the existing shape retention technology have become serious obstacles to high-quality textiles, and can no longer meet people's needs for high-quality clothing in modern society.
