Optimization of Technology for the Use of Spinning Waste in Yarn Production

Abstract

The paper considers issues related to the development of technology for the use of spinning waste in the production of cotton yarn. The process of forming a column of cotton fibers with included waste in an improved feeder-hopper of a loosening-scutching unit designed for cleaning from foreign impurities and dust is theoretically analysed. The optimal design parameters of an improved hopper-feeder with perforated walls have been determined depending on the performance of the loosening-scutchingunit. The approximate distribution of the concentration of foreign impurities and dust is determined depending on the technological and design features of the improved hopper-feeder with perforated walls. The optimal technological parameters of the post-treatment of the formed fibrous layer of cotton after the hopper-feeder have been determined.
