Method for manufacturing sheet-like product

Abstract

Provided is a production method in which a sheet-like article that has high moist heat resistance and has good surface quality and texture can be produced, regardless of the coagulation technique used for the polyurethane, by an environmentally friendly manufacturing process that is designed to cause reaction of a crosslinking agent while maintaining the texture possessed by the material before crosslinking. The production method for sheet-like articles is a sheet-like article production method characterized by impregnating a fibrous base material with water dispersed polyurethane as a binder, coagulating it to provide a sheet, adding a solution or dispersion liquid of a crosslinking agent to the sheet, and then heating it at a temperature of 100° C. or more and 200° C. or less.
