Abstract
27 samples of fabric were prepared from the cotton yarns of 600, 1000 and 1400 twists per meter; the structures of the fabrics were plain weave; 4-harness twill and 8-harness satin. The crease resistance along the warp and weft yarns were measured and the following results were obtained: The crease resistance of the fabric decreases in general with the increase of the twist but in some of them it increases or goes through a minimum or maximum point.
The authors indicated the above changes in the crease resistance in relation to the twist numbers of the warp and weft yarns. The freedom of the single filaments in a yarn decreases gradually with the yarn-twist but the yarn is, at the same time, reinforced by the twist. The above phenomena seems to be caused by the change in the relative intensity of these two factors.
