Influence of Changes in the Mechanical-Physical Properties of Fibers on Yarn Quality

Abstract

This article investigated and examined the change in the basic physical and mechanical properties of fibers and their degree of purification in the technological process of spinning. The laws of the influence of the degree of purification on the basic physic mechanical properties of fibrous materials in the process of opening, cleaning and carding were also studied. The basic purpose of this study determine the to optimizing the technological parameters of spinning process for normal yarns by using fiber which is estimated as the average quality by the Uster®.  Short fiber cotton was used to produce normal counts, i.e. Ne 30 normal yarns, spun on Zinser 72 Ring frame. Yarn produced by spinning processes from semi-finished products collected at different type technological parameters of spinning process shows variable yarn properties. The study of all these parameters plays important role to achieve better quality output of the spinning processes.
