    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.

    摘要: A composite fabric useful as a substratam sheet for artificial leather is composed of a woven or knitted fabric constituent and at least one non-woven fabric constituent consisting of numerous fibrous bundles composed of a plurality of individual fibers arranged parallel to each other, and varying in the number of the individual fibers from which the bundles are formed, and numerous individual fibers independent from each other and from the fibrous bundles, the individual fibers and the fibrous bundles being randomly distributed and entangled with each other to form a body of non-woven fabric, and the non-woven fabric constituent and woven or knitted fabric constituent being superimposed and bonded together, to form a body of composite fabric, in such a manner that portions of the individual fibers and the fibrous bundles of the non-woven fabric constituent penetrate into the inside of the woven or knitted fabric and are entangled with a portion of fibers in the woven or knitted fabric constituent.
