The technological process of yarn production is long and complicated, therefore costly.

Abstract:

 The technological process of yarn production is long and complicated, therefore costly. Modern spinning systems tend to shorten this process by assembling machines in technological lines or by eliminating some of them. This task is facilitated by modern draft regulators, whose application is to improve the quality of yarn produced . Especially important is the non-uniformity of the linear density of spun products, which should not increase when shortening the technological process, hence, the number of joints in the product should not be decreased within the process. This work presents an analysis of the possibilities of the manufacture of polyester yarns using the shortened cotton system when applying a carding draft regulator with a modified operation algorithm which takes into consideration the phenomenon of spinning sliver retardation after the short-section regulation.
