Abstract

In order to study basic phenomenon of dynamic drape of filament weaves, damping behavior of fabric shear vibration in the large shear deformation region (>0.035rad); that is, the region in which the vibration damped non-linearly with time, was investigated in detail in relation to shear property of the fabric. It was shown that the non-linearity increased with the shear angle and the increase was mainly caused by the increase of shear hysteresis. The damping behavior of silk filament weaves was typed in four patterns and the patterns corresponded well with the four combinations of basic mechanical parameters of shear property; G and 2HG, in the degree of changes with shear angle, obtained by KES system. Bending vibration behavior changed less than the shear vibration for four typed silk fabrics, and it was suggested that dynamic drape behavior of _??_ clothes was more related with shear property than bending property.
