Role of fibre, yarn and fabric parameters on bending and shear behaviour of plain woven fabrics

Abstract

Influence of fibre blend, yarn count and fabric sett (thread density) on bending and shear rigidities of plain woven fabric has been studied. Fifteen plain woven square fabrics have been woven using 20, 30 and 40 Ne yarns of three different blends (100% cotton, 100% polyester and 50:50 polyester-cotton). The fabric samples are produced at three levels according to the Box and Behnken design of experiment methodology. Fabric bending and shear rigidities are measured by using Kawabata Evaluation System (KES) at low stress region. An increasing trend of fabric bending and shear rigidities are observed with lower proportion of polyester, coarser yarn count and higher fabric sett. Yarn count is found to be the most important parameter influencing fabric bending and shear rigidities followed by fabric sett and blend proportion of polyester. A strong degree of association is found between bending and shear rigidities of fabric.
