The ease-abilities of several man-made leathers for apparel use, having different structure and finishing, are investigated and correlated with their mechanical properties. The three dimensional shape formed by eased-in is evaluated by Moiré Topography method.
The ease-ability along machine direction of the leather is higher than along the other directions but the difference is not so large. In general, the ease-ability of the leathers is lower than that of woven fabrics. The significant correlations between the ease-abilities and mechanical properties (tensile, bending, shearing and compression) are obtained.
The vertical fold of the three dimensional shape formed by eased-in is higher and the peak of vertical fold is nearer to the ease-line in leather than in woven fabric.
