Abstract

A substrate having an appearance similar to that of nubuk-leather or pile-leather, respectively, or of a textile pile consists of a textile carrier body being at least partially impregnated with a, preferably cross-linked, polymeric synthetic plastics material consisting of a foam which has open cells formed by introducing air and optionally has closed cells formed of hollow microspheres. The textile carrier body consists of a fleece or of a knitting, preferably of a crimped fleece of synthetic fibres, which is needled together with a knitting or with a fleece, strengthened by thermal embossing, in such a manner that the fibres extend through the knitting. The knitting may consist of a roughened stockinet, i.e. a stockinet having opened loops. The carrier body is ground at least at its one impregnated surface and is thus rough and can be provided with a coating.
