    • A method of leather processing which, without need of using a large amount of a hardener, etc., can yield a leather which can retain a three-dimensional shape, especially one with a fine, highly attractive design, for a long time and has high stretchability and high recovery while retaining the flexibility inherent in leathers; and a leather of a three-dimensional shape, especially a processed leather of a pattern and shape such as ones formed by wringing the leather together. The method comprises deforming a flat leather into a three-dimensional shape having recesses and protrusions and heating at least part of either or both of the protrusions (2) and recesses (1) to cure the heated parts and thereby cause the leather to retain the three-dimensional shape. More specifically, the protrusions and the recesses are partly heated while keeping the remaining parts being insulated from the heat to cure the heated parts only.
    • 一种皮革加工方法,无需使用大量的硬化剂等,可以产生可以长时间保持三维形状,特别是具有精细,高吸引力的设计的皮革,并且具有 高拉伸性和高恢复性,同时保持皮革固有的柔韧性; 以及三维形状的皮革,特别是通过将皮革拧在一起而形成的图案和形状的加工革。 该方法包括使扁平皮革变形成具有凹陷和突起的三维形状并加热突起(2)和凹部(1)中的一个或两个的至少一部分,以固化加热部分,从而使皮革保持 三维形状。 更具体地,突出部和凹部被部分加热,同时保持其余部分与热绝缘而仅固化加热部件。
