Promising Effect of Processing Parameters on Yarn Properties in Rotor Spinning

Abstract

Fabric characteristics significantly depend on the physical properties of yarn and the qualities of rotor yarn greatly governed by processing parameters. The aim of this study is to observe the effect of processing parameters such as rotor diameter and speed on the physical properties of yarn in rotor spinning process. Mixing of spinning waste with the virgin cotton is a common phenomenon in rotor spinning. 0.11 sliver hank of 100% cotton fibre with 65% virgin cotton and 35% wastage was used to produce 12 Ne yarn. The favorable impact of processing parameters on the yarn characteristics were accessed by coefficient of variation (CVm %), imperfection index (IPI), hairiness, tenacity, count strength product (CSP) and force at break. The yarn qualities were improved with increasing of rotor speed and rotor diameter.
