Abstract

Abstract Disclosed is a suede-like raised woven fabric of a combination weave having raised extra fine fibers on the surface thereof, which fabric comprises a continuous multifilament yarn used as warp, a yarn of a bundle comprising continuous extra fine filaments used as a first weft and a continuous multifilament yarn used as a second weft. The preparation of the raised fabric comprises weaving a fabric using appropriate material yarns, subjecting the fabric to heat treatment and subjecting the fabric to raising. The yarn constituting the first weft may be produced from a bundle of multi-core composite filaments by removing a component surrounding the cores. The fabric has an excellent suede-like touch, appearance and feel.
