Siro compact spinning blended yarn of cotton crystal and long stapled cotton, and spinning technology thereof

Abstract

The invention discloses a siro compact spinning crystal cotton, long-staple cotton blended yarn and its spinning process. The dry weight ratio of crystal cotton and long-staple cotton is: crystal cotton: 30-50%; long-staple cotton: 50-70%. Including: (1) raw material processing: raw material health preservation, adding and blending crude oil, anti-sugar agent, antistatic agent; (2) cleaning and carding process: mixing and opening of raw materials; further mixing and opening; carding and removing impurities to form raw sliver ; (3) Pre-drawing process: drafting, and; (4) Strip and coiling process: and, roll; (5) Combing process: further carding to remove neps, impurities, and short fibers; (6) Drawing process: further drafting and merging; (7) Roving process: drafting, twisting, winding, forming; (8) Spinning process: further drafting by Siro spinning, twisting and rolling of compact spun condensed fibers Winding and forming into spun yarn; (9) Winding process: further remove defects, wind and form into bobbin. The invention solves the problem of difficult spinning of crystal cotton and widens the market space of crystal cotton.

Description

technical field [0001] The invention relates to a yarn made of natural fiber "crystal cotton" and long-staple cotton (combed) for Siro compact blending and its spinning process. Background technique [0002] At present, the primary natural fibers used in textiles in the world's textile industry are divided into two categories: plant fibers and animal fibers. Various animal furs and silks are animal protein fibers. Among plant fibers, cotton is the one that produces fibers at one time. [0003] Cotton is a major player in global textiles. Since its appearance, it has a history of 7,000 years. The global textile industry and raw material industry have been looking for a fiber similar to cotton, but have been unsuccessful. But in 2005, Hu Huimin, chairman of Shanghai Magic Tree Biotechnology Co., Ltd., discovered a natural plant fiber crystal cotton in the fruit of a certain shrub in the virgin forest of Yunnan. It is similar to cotton in terms of performance, and is super...

Problems solved by technology

[0006] The relative density of crystal cotton fiber is very small, very light, and the fiber is easy to float during the spinning process; the surface of the fiber is very smooth, the cohesion between the fibers is poor, and it is difficult to comb into a web and sliver; the fiber is rigid and fragile, so it is difficult to process pure spinning
