ABSTRACT A process for the preparation of a suede-like raised woven or knitted fabric is described,wherein a raised woven or knitted fabric is first prepared,comprising extra-fine fibres, the monofilament denier of which is in the range of 0.0001 to 0.8. An aqueous liquid of hydroscopic and heat-active urethane pre-polymer having an isocyanate group blocked by bisulfites is applied to the fabric in a dry amount of 1 to 20% by weight of urethane pre-polymer to weight of fabric. The applied fabric is heat-treated at a temperature of 100 to 120°C to form polyurethane polymer in the fabric, and finally, at least one surface of the fabric is buffed. The raised woven fabric may comprise a weft yarn consisting of the extra-fine fibres with a warp yarn of crimped textured filament. The Ph of the aqueous liquid may be in the range of 5.0 to 7.0 measured at 20°C.
