Effect of fibre cross-sectional shape on handle characteristics of polyester-viscose and polyester-cotton ring and MJS yarn fabrics

Abstract

The relationships between handle characteristics of polyester-viscose and polyester-cotton ring and MJS yarn fabrics and yarn bulk and rigidity have been studied using FAST evaluation system. Generally, MJ S yarn fabrics are relatively thicker, more rigid and provide a lower shear rigidity and enhanced formability. There are significant changes in the

compression, shear rigidity and formability with variation in fibre profile, and a marked improvement in these characteristics is obtained with trilobal polyester fibre. Increased polyester component leads to a noticeable increase in bending and shear rigidities. A polyester-cotton fabric has been found preferable to a polyester-viscose fabric in respect of fabric handle.
