Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an intermediate product of soft artificial leather increased in mechanical resistance. SOLUTION: The method comprises (a) a step for producing a microfibril nonwoven fabric intermediate product comprising microfibril of one or more polymer selected from polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyacrylonitrile and polyamide, (b) a step for producing an intermediate multilayer product containing at least one layer of the above-mentioned nonwoven fabric microfibril intermediate product and at least one layer of reinforcing textile products by bonding with an adhesive, and (c) a step for obtaining the multilayer intermediate products impregnated with polyurethane by impregnating one or more polyurethane solutions to the multilayer intermediate products produced in the step (b).
