Abstract

Bending rigidity of plain weave cotton fabric in principal directions (warp, weft) and 45º bias was investigated. Textile samples were prepared by finishing them with different concentrations (0 g/l, 5 g/l, 10 g/l, 15 g/l) of polyvinyl acetate based temporary stiffener. Two different experimental methods, a conventional cantilever method and buckling wave method were applied. Sensitivity range of the apparatus to the variation of stiffness was investigated. Linear dependence between bending rigidity and concentration of stiffener, obtained with the cantilever method, was supported with additional samples treated with 2.5 g/l and 7,5 g/l concentrations of stiffener. The influence of stiffener’s concentration upon changes of buckling wave’s geometry was analysed.
