ABSTRACT:
The disclosed composite fabric, useful as a substratum for artificial leather, comprises a woven or knitted frabic and at least one non-woven fabric firmly bonded to the woven or knitted fabric, and is produced by providing a precursory sheet with two or more layers from a woven or knitted fabric and one or more fibrous webs which consist of numerous extremely fine fibers having an average diameter of from 0.1 to 6.0 microns, and uniformly impacting the fibrous web surface of the precursory sheet with numerous fluid jets ejected under a high pressure of from 15 to 100 kg/cm.sup.2, at a ratio of a total impact area of the fluid jets on the precursory sheet surface to an area of the precursory sheet surface to be impacted of at least 1.5, in order to allow the extremely fine fibers in the fibrous web to randomly entangle with each other and also to allow a portion of the extremely fine fibers to penetrate into the inside of the woven or knitted fabric and entangle with a portion of the fibers in the woven or knitted fabric.
