METHOD FOR PRODUCING PRODUCT COMPOSED OF SHEET-LIKE MATERIAL HAVING GOOD DYEING PROPERTY AND JOINING PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a molded product having good dyeing property and joining property, capable of simply carrying out treatment without accompanying complicated operation such as control, or the like, of processing treatment condition and free from occurrence of dyeing unevenness when applying a readily dyeable primer resin to a sheet-shaped material, prior to process a sheet-like material mainly composed of a sheet-shaped fiber aggregate and a polyurethane, particularly a leather-like sheet-shaped material used as one material to shoes, or the like, by injection molding method.;SOLUTION: This method for producing the molded product comprises applying methylethyl ketone or a treating agent mainly composed of methylethyl ketone to at least injection molded surface of the molded product and integrally molding the molded product with an other member by an injection molding method, when producing the product by integrally molding with other member the molded product composed of a sheet-shaped material (A) containing a polyurethane or an elastic polymer mainly composed of the polyurethane in a sheet-shaped fiber aggregate or a sheet-shaped material (B) having a coating layer comprising a polyurethane or an elastic polymer mainly composed of the polyurethane on one surface or both surfaces of the sheet-shaped fiber aggregate.;COPYRIGHT: (C)2006,JPO&NCIPI
