To obtain a fabric having design rich in variation by applying crease finishing to a fabric, carrying out pleat processing of the fabric in plural steps and subjecting a mixture of various pleats having undefined length and width to wet crushing processing.

A fabric comprising a thermoplastic fiber is packed into doughnut-like ring of a container having a double cylinder, in which air vent is provided and heat-treated and subjected to crease processing to afford a semi-product 7 and paper 16 is applied to the lower face of the fabric while spreading width of the fabric and the fabric is subjected to pleat processing through a pair of nipping heat rolls 10 and 11 having different surface rates and paper 16 is superposed to the upper face side of the semi-product 7 and the semi-product 7 is again subjected to pleat processing through a pair of nipping heat rolls 13 and 14 to provide the object finished product, in which various pleats different in length, width and direction are mixed, subjected to crush processing.
