We analysed a shearing deformation behaviour of fabriclike model, which was made of rubber strings (warp direction) and glass rods (weft direction), by the dynamical method described in a previous paper. It was found that the relationship between the properties of model elements and the one of glass rods may be shown by the formula.
Where f: the numbers of rubber strings, n-1: no_??_ of glass rods, l: an interval of glass rod in cm, A: contact area between glass rod and rubber string in cm², E: young's modulus of rubber string in dyne cm^-2, and Es: apparent shear modulus of fabric shear in dyne.
The contact area was determined by means of Finch's method i.e. carbon black coating method and Heltz's theoretical calculus.
From this result, we obtain some useful hints for the analysis of more complicated cases as apparel fabfics.
