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 co-efficient 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.

Highlights

The process of converting fibers into yarn is complex which requires many investigations and new technical & technological solutions [1]
The volume of production on rotor spinning has increased in recent years which are quite understandable considering the present trend in the production and consumption of textile products [5]
CVm% were decreased with the increment of rotor speed and rotor diameter

Summary

Introduction

The process of converting fibers into yarn is complex which requires many investigations and new technical & technological solutions [1]. There are many spinning systems are available such as ring spinning, air vortex spinning, friction spinning, disc spinning, solo spun spinning, Siro spinning, air jet spinning, wrap spinning and rotor spinning [2]. The best process of producing better quality yarn from very poor grade of cotton and even from wastage is rotor spinning. Rotor spinning gives a new era to produce more uniform, fuller, aerated and regular in strength cotton yarn [6]. Rotor spinning is a recognized spinning system mainly for medium and course counts. The yarn characteristics of rotor spun yarn are affected by many factors mainly related to raw material, machine and processing parameters
