Study on Mechanical Properties of Polyester Woven Fabric (II)- Honlinearity of Shear Properties -

The shear behavior of fabrics is an important characteristic in fabrics whose end-use is for apparel purpose. The shear properties of the fabrics influence the draping, pliabiltiy and hand of fabrics. Moreover, the shearing behaviors of fabric have been applied in designing air ship, space suit and inflatable shelters. Therefore shear behavior plays very important role among the various mechanical properties of fabrics. The purpose of this paper is to analyze shear properties of polyester fabric in association with such fabric structural parameters as twist level, fineness, fabric density. Weave structure and processing factors. So far, correlation between shear properties and fabrics structural parameters and processing shrinkage with weave structure is examined. What is more. non-linear correlation between shear properties and fabric structural parameters is analyzed. Finally the regression analysis between processing shrinkage and shear properties and fabric structural parameters is carried on.
