Abstract

Manufacture of yarn from Polyester- cotton core yarn is one of the most important developments in textile Industry. Use of core yarns is mainly aimed to improve the strength, comfort, durability, aesthetic and other functional properties of the final yarn. The article reports the results of investigation on core spun yarns made from polyester filament as core and cotton as sheath material.

Polyester filaments with different proportions were chosen for the core component and cotton at sheath total six different core yarns were made and results were compared with 100% cotton Ring Spun yarn.

It is observed that core yarns are having improved physical properties over that of 100% cotton ring spun yarn.

Introduction

Core yarn structure consists of two components, one of which forms the center axis or core of the yarn and other is the covering. Continuous multifilament yarn generally used as a core while cotton staple fibers are used for covering the filaments or used as sheath material.

Core spun yarn shows some improved characteristics over 100% spun staple yarn on 100% filament yarns. To improve the strength and comfort core spun yarn is preferred over blended staple spun yarn. There is a phenomenal improvement of durability & aesthetic property are observed by using core spun yarn. As the cotton is wrapped over polyester filaments improvements are on yarn properties like moisture absorption, heat resistance, air permeability, depth of shed in dyeing. The tensile strength of yarn increases because of presence of Polyester Filament at core, which is the main load carrier.
