Abstract
A suede-like or deer skin-like raised woven or knitted fabric having at least one raised surface is produced by providing a woven or knitted fabric using a yarn consisting of synthetic hollow composite fibers each composed of two or more fiber-forming polyester constituents and two or more fiber-forming polyamide constituents and having a hollow space surrounded by the polyamide and polyester constituents which are arranged alternately with each other and adhered to each other side-by-side so as to form a tube-shaped body, and raising a surface of the fabric while allowing the hollow composite fibers located in at least the raised surface portion of the fabric to be divided into numerous very fine fibrils consisting of said polyester and polyamide constituents.
