Patent ID: 8795780

Claim:
A method of preparing a textile fabric sheet having stain and liquid resistance, said textile fabric sheet comprising a fabric substrate; a polyurethane coating layer; and a silicon coating layer in this order, said method comprising: (i) providing the fabric structure; (ii) knife-coating a polyurethane coating composition at least once on one surface of the fabric substrate, drying the polyurethane coating composition, and forming the polyurethane coating layer having thickness of 1 to 200 μm on the one surface of the fabric substrate; and (iii) coating a silicon coating composition on the polyurethane coating layer and drying the silicon coating composition to form the silicon coating layer of a thickness of 1 to 30 μm to give the textile fabric sheet comprised of the fabric substrate, polyurethane coating layer and the silicon coating layer, in this order; wherein in step (i), the fabric substrate is knife-coated twice with the polyurethane coating composition; and during knife coating, a diameter angle of the knife is 20 to 90 degrees; and wherein the polyurethane coating composition includes a polyurethane resin at 10 to 100 g/m 2 , a curing agent and an organic solvent.
