The process for mafg. suede type artificial leather using non-woven fabrics made by a seaisland type complex fiber of ultra-fine fibrousness, is composed of the steps of: 1st, dipping the nonwoven fabric into hot water, then shrinking, and extracting the sea type component; 2nd, pressing by a sylinder type dryer; 3rd, adding the polyurethane polymer contg. 5-80 wt.% of collagen w.r.t. the wt. of solid of the polyurethane; 4th, washing, dring and buffing the product. The ave. particle size of collagen is 8-20 micrometer. The obtd. artifical leather has improved high density, wettability, flexibility, light resistance and stiffness.
