Abstract

Research was carried out to study the quality indicators of yarn. For this purpose, yarns were obtained under laboratory conditions from fibers of currently zoned varieties and varieties under trial, and their quality indicators were determined using modern equipment. The results show that, compared with yarn from cotton fiber of the industrial variety S-9085, yarns from the industrial varieties KK-3565 and KK-3523 had, respectively, 11.6% and 17.1% lower strength, 1.1% and 5.7% lower specific breaking strength, 7.1% and 3.1% higher coefficient of variation of strength, 9.9% and 9.0% higher elongation at break, and 2.7% and 21.2% higher coefficient of variation of elongation at break. It follows that the physical and mechanical properties of yarn from S-9085 fiber have been proven superior to those of yarn from other industrial varieties. To produce high-quality yarn, which is in high demand, spinning mills should above all choose the fiber composition correctly.
