ABSTRACT:
The suede-like fabric according to the invention is produced by the process which comprises the steps of supplying aqueous chemical composed of acrylic resin, emulsifying agent and water to treating rollers through chemical coating means; passing the raw fabric cloths between the treating rollers having the chemical supplied and supporting rollers to produce a uniform chemical coating of 70˜200 g/m2, the rollers pressing and fixing the passing raw fabric cloths; de-watering and drying the raw fabric cloths having the chemical coating fixed under pressing in a thermal chamber maintained at a temperature between 80 and 200° C.; and heating and pressing the dried raw fabric cloths by means of heating rollers at a temperature between 130 and 150° C. to finish the acrylic coating through this ironing step; and a further step of rubbing-off the coated surfaces of the raw fabric cloths for abrasion by rotating a striker drum made of wood for a predetermined period. The suede-like fabric according to the invention offers the advantage of reducing the effort and expense for maintenance of products and can provide, in spite of a new product, a comfortable and fashionable atmosphere of a long-used old leather due to the appearance of the fabric surface so as to produce a unique optical effect which is not felt from ordinary leather products (FIG.4).
