Pure cotton yarn production method utilizing seamless joint of roving and finespinning

Abstract

The invention discloses a pure cotton yarn production method utilizing seamless joint of roving and finespinning. Through reasonable raw cotton matching and through an automatic doffing roving frame,an all-digital integrated spinning automatic doffing finespinning machine and an automatic roving and finespinning conveying system, seamless joint of the roving process and the finespinning process in the pure cotton yarn production process is realized, continuous roving and finespinning production is realized, production labor is significantly reduced, moreover, influence of yarn faults and hairiness caused by touch, friction, collision and the like in the transporting process of a roving drum in the operation process is reduced, labor is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a method for producing pure cotton yarn using thick and thin yarns. Background technique [0002] At present, in addition to policy, environment and cost impacts, labor costs and shortages have become a grim reality for the textile industry. Due to the severe labor shortage, textile enterprises in some regions have chosen to suspend or partially suspend production, which has seriously affected the development of the textile industry. The new automation equipment such as blowing-carding unit and automatic can changing device of draw frame that have been widely used in the industry, especially the promotion of high-speed and large-package equipment, has greatly reduced the labor required in the pre-spinning process. At present, most of the labor is still concentrated in the three processes of coarse, fine and winding. The work of taking, inserting and transporting yarn after doff...

AI Technical Summary

Problems solved by technology

At present, foreign thick and thin joints and thin joints have been widely used, but the product price is expensive, which is more than three times the price of domestic assembled thick and thin joints, and the technology blockade and market monopoly are imposed on our country; after decades of development in China, great achievements have been made, but Compared with international advanced equipment, there is still a big gap in terms of intelligence, continuous level, online quality monitoring, equipment stability and reliability, etc.
