CHANGE IN TECHNOLOGICAL AND QUALITATIVE INDICATORS OF CARD SLIVER FROM LOW-GRADE FIBER AND FIBROUS WASTE DURING THE CARDING PROCESS ON MODERN CARDING MACHINES

Abstract

The study of the factors influencing the course of the carding process and the quality of the carding sliver produced from low-grade fiber and fibrous waste, or rather the modeling of its unevenness, is one of the most actual tasks in the modern textile industry. In this article, researches and experiments were carried out to identify the influence of factors affecting the content of neps in the card sliver and a complex indicator of the structure of the card sliver. Using mathematical methods for planning experiments, a general regression model of the object under study was obtained for a relatively small number of tests and an isometry of the dependence of the factors under study on the quality of the card sliver was constructed using the MatCad computer program. Based on the studies of the process of carding low-grade cotton fiber and fibrous waste, as well as the joint analysis of the obtained regression and isometric equations based on technological and economic requirements, results were obtained for the analysis and optimization of the carding process on modern carding machines.
