Interrelationship Research of Bending Properties between Yarn and Fabric

The bending properties such as the bending rigidity and hysteresis with various twists of yarn and densities of grey fabric and finished fabric were studied for analysing the effect of finishing process. As a result, bending rigidity of finished fabric was smaller than those of yarn and grey fabric, and the effects of yarn twist and fabric weft density to the bending rigidity were not shown in the state of grey fabric but in finished fabric. The hysteresis of the finished fabrics showed less values than those of the yarn and grey fabric, and the effects of finishing processes to the bending hysteresis were larger than those of the yarn twist and the fabric density.
