Abstract

Abstract A rubber coated fabric comprises a base fabric and a coating material laminated on at least one side of the base fabric. The coating material comprises, as its main ingredient, a product of reaction between liquid rubber and polyisocyanate. According to the invention, there are also provided methods for producing the rubber coated fabric comprising steps of mixing and stirring liquid rubber and polyisocyanate together in a mixing-dispensing machine and coating the mixed liquid rubber and polyisocyanate on a base fabric either directly or by means of a release paper or film. According to the invention, curing of the coating material is performed in a low temperature of 120° C. or below resulting in various advantages including saving of energy consumption, prevention of curling of the product and of volatilization of low-boiling point ingredients. In the rubber coated fabric, adhesion of dusting powder to the coating material is excellent and little dusting powder applied to the coating material comes off. If a fabric treated previously in a water and oil repellent is used as the base fabric, leaking of the coating material from the base fabric is prevented and a rubber coated fabric of excellent appearance, peeling resisting property and draping quality is obtained.
