ABSTRACT:
A soft and strong composite sheet for artificial leather comprises a woven or knitted fabric and a non-woven layer intertwined with the fabric. The fabric comprises a high twist yarn and the non-woven layer has in it a number of fibers of a length greater than 20 mm, the number being at least 10 fibers/cm.sup.2. The sheet includes a binder.
A method which can be employed for making such a sheet comprises superimposing on one another a fabric constructed at least partly from a highly twisted yarn and a non-woven fiber web, intertwining fibers of the non-woven fiber web with the said fabric by needle punching and thereafter applying to the resultant structure a binder.
