Abstract

The work described in this study focuses on determining the influence of various parameters such as assembly and twisting nozzle pressures, yarn count, and material type on the properties of two-ply air-jet spun yarns produced using a spin-assembly-winder concept on the PLYfiL system. The results show that the tenacity, irregularity, and hairiness of both untwisted and twisted yams are influenced by changes in the nozzle pressure. Lower pressures in this range generally result in better tenacity values for twisted yarns. It is also likely that the properties of fibers and sliver are factors that affect yarn quality in air-jet spinning.
