A COMPARATIVE STUDY OF DENIM FABRICS DEVELOPED USING RING AND ROTOR BAMBOO/COTTON YARNS

Abstract

In this paper, the functional properties of bamboo, cotton and bamboo/cotton blended denim fabrics have been studied. In this study, twenty denim fabric samples have been developed using ring and rotor spun yarns with different blend proportions of bamboo/cotton like 70:30, 50:50 & 30:70. The fabric samples were evaluated for their comfort and mechanical properties like air permeability, water vapour permeability rate (WVTR), Over all Moisture Management Capability (OMMC), crease recovery, tensile and tear strength. It is observed that with increase in the bamboo content in the blend improves the comfort and mechanical properties in both the ring and rotor yarn fabrics. Ring yarn fabrics exhibited better moisture management properties, water vapour transmission rate , tensile and tear strength than the rotor yarn fabrics. In contrary, rotor yarns have better air permeability, crease recovery, fabric assistance than the ring yarn fabrics. 70:30 bamboo/cotton blends have better comfort and mechanical properties than other blends
