Vibrational Property of Filament Woven Fabrics Based on Shear Deformation

Abstract

In order to study basic phenomenon of dynamic drape of filament woven fabrics, dependency of vibrational property of woven fabrics based on shear deformation on fabric tension was investigated precisely in relation to shear property of the woven fabrics. The shear vibration of fabric dampled linearly with time in a small shear deformation range (<0.035rad) under all the fabric tensions examined here (0.1-3.5kg/m). This means the vibration damps by inter-fiber and/or inter-yarn friction in the woven fabrics. Optimum range of the fabric tension where the shear vibration continued the longest was recognized to exist experimentally and theoretically. The damping ratio correlated well with a combined characteristics of shear property measured by KES system; 2HG0/_??_G0, and this could be considered as a parameter of shear vibrational property of woven fabrics. Vibration of silk woven fabrics continued longer than that of the similar type of silk-like polyester woven fabrics.
