Abstract

This article presents a comparative analysis of the properties of cotton yarn spun on aerodynamic compact spinning and open-end rotor spinning systems. Yarn samples with a linear density of 50 Tex, 37 Tex, 30 Tex, 25 Tex, and 20 Tex were spun both on the aerodynamic compact and rotor spinning systems using the same finisher drawn sliver of medium staple cotton which were produced by a specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, and tensile behavior (strength in count strength product, elongation percentage) of the yarn samples were assessed and analyzed. The results revealed that aerodynamic compact spun yarn had a lower unevenness and mass variation, a higher imperfection in case of a finer count, less hairiness, higher tensile strength, and lower elongation% compared to the open-end rotor spun yarn samples. Finally, paired- samples t-test and regression analysis were carried out by using IBM SPSS 25 to check the significance of yarn quality parameters and correlation among them.

Highlights

The global competitive situation has forced the modern textile market to focus vigorously on issues like productivity and cost reduction in manufacturing yarn and fabric while maintaining the quality at a high level

The above study was carried out to determine the significant differences in the properties of compact and open-end rotor spun yarns, which were influenced by the inner structure of the yarns and their linear density

Summary

Introduction

The global competitive situation has forced the modern textile market to focus vigorously on issues like productivity and cost reduction in manufacturing yarn and fabric while maintaining the quality at a high level. The yarn is spun in a simplex machine and ring frame sequentially. The production rate in the ring frame determines the production output [1] [2]. In the case of ring spinning, the twist is inserted into yarn by the aid of a rotating traveler. In compact spinning, tension differences between fibers during the twist insertion are smaller than those in-ring spinning due to the reduction of the spinning triangle [4]. It has been claimed that compact spinning has the possibility of attaining yarn strength identical to that in typical ring yarn with approximately 10% lower twist [5]. The production rate of open-end rotor spinning (OERS) is up to 200 meters per minute for up to 20 Tex linear density [6]
