Abstract

Yarn characteristics extensively influence by spinning process. The aim of this study is to observe the effect of conventional ring and compact spinning processes on properties of yarn. 100% CIS-Turkey cotton was used to produce conventional ring card yarn and card compact yarn. The twist per inch of 16.99 and 19.57 were settled to fabricate 20 Ne and 30 Ne count of yarn respectively both for conventional ring and compact spinning. The positive effect of spinning process on the yarn properties were evaluated by co-efficient of variation (CVm %), imperfection index (IPI), hairiness, tenacity, count strength product (CSP) and elongation (%). The results exposed that yarn qualities of compact spinning were exhibited higher than conventional ring spinning.

Highlights

Spinning is the process of producing yarn from various raw fibre materials
The yarn hairiness is one of the most important parameters influences the performance of subsequent processes, appearance and end use of the final fabric
Less hairy and more even yarns were produced than conventional ring spinning

Summary

Introduction

Spinning is the process of producing yarn from various raw fibre materials. Characteristics of the yarn differ based on the material used, fibre length, alignment, quantity of fibre used and degree of twist [1]. Achievement of improved yarn quality is the main goal of any spinning company that will ensure better competitiveness. Development efforts in ring spinning were focused on improving the existing technology and incorporating automation and process-linking capabilities. The advancement of spinning technology has generally altered the relationships between fiber properties and yarn quality. Different spinning processes are likely to involve different fiber–machine interactions, which in turn alter the optimum combinations of fiber properties [2]
