To readily produce a hairy fabric, wider than a gray fabric while keeping the color variation same as the conventional product by dyeing the fabric with the hair consisting of a nonwoven fabric composed of an ultrafine synthetic fiber and including a polyurethane resin, and carrying out a simultaneous dry heat set and tentering set of the dyed fabric at a specific temperature and at a specified tentering rate.
A hairy fabric consisting of a nonwoven fabric composed of a polyester-based or polyamide-based ultrafine synthetic fiber having 0.001-0.1 de single fiber size, and a polyurethane resin regulated so that the weight ratio of the ultrafine synthetic fiber to the polyurethane resin may be (90:10)-(35:65) is dyed, and the dyed fabric is simultaneously subjected to a dry heat set and a tentering set at 5-40% tentering rate satisfying the equation [tentering rate (%)]={1-(A/B)} ×100 (A is the width of the fabric after the dry heat set; B is the width of the fabric before the dry heat set), at ≥130°C, preferably 130-220°C, more preferably 150-190°C. The resultant fabric is subjected to a reduction cleaning treatment.
