Effects of Structure and Finishing on the Mechanical and Dimensional Properties of Wool Fabrics

Abstract

We have investigated the effects of the interaction between fabric cover factor and finishing on fabric properties with a systematically designed array of fabric structures and finishing treatments. Permanent setting induced in finishing had the greater effect on fabric mechanical and dimensional properties. For lightly finished fabrics with a low degree of set, the influence of cover factor was significant. For the entire range of plain weave and twill fabrics, the hygral expansion could be related to the weave crimp and the shear properties of the fabric. There was also a contribution from yarn cur vilinear expansion.
