The present invention provides a method for manufacturing a sheet-like product having good surface quality and texture and, in particular, excellent moist heat resistance, by means of an environmentally-friendly manufacturing step in which, regardless of the polyurethane hardening method, a reaction with a crosslinking agent is performed and the texture of the product is maintained so as to be similar to the texture before crosslinking. This method for manufacturing a sheet-like product is characterized in that a liquid solution, in which a crosslinking agent is dissolved or dispersed, is applied to a sheet obtained by impregnating a fibrous base material with a water-dispersed polyurethane as a binder and hardening the impregnated material, and then the sheet is heated to 100°C–200°C. |
