Abstract

The compact spinning technique is one of the major improvements of classical ring spinning which has superior yarn structure and quality in terms of hairiness and strength. With a view to achieve, this paper reveals the significant correlation of differently aged lattice aprons of sussen compact spinning attachment with different yarn quality characteristics and fitting both simple and multiple linear regression equation. The 100% cotton compact yarns of 30’s Ne are spun with differently aged lattice apron from the same cotton fibers, same roving and on the same spindles of the same ring frame with keeping the machine speed and doff length constant. The unevenness of mass variation U%, imperfection index (IPI), hairiness (H), countstrength- product (CSP), tenacity, elongation% of yarns are tested with quality control equipment and analyzed. Comparing with the new to 9-month aged lattices apron the evenness, strength, imperfections, and hairiness of produced yarns show decrement trends with an increment in elongation. The established multiple linear regression fitting line elicits the manufacturers to predict the quality of compact ring spun yarns.
