MULTILAYER COMPOSITE SHEET USEFUL AS A SUBSTRATE FOR ARTIFICIAL LEATHER

摘要

A multilayer composite sheet useful as a substrate for artificial leather, comprises at least three fibrous layers, namely, a superficial layer (A) consisting of a spun-laid web composed of extremely fine fibers having an average denier of 0.5 or less and three-dimensionally entangled with each other; and intermediate layer (B) consisting of a web of staple fibers having a length of 50 mm or less and entangled together; and a base layer (C) consisting of a woven or knitted fabric, the above-mentioned three fibrous layers being superimposed on each other and combined together in such a manner that a portion of the fibers in each layer penetrates into the adjacent layers and becomes entangled three-dimensionally with the fibers in the adjacent layers.
