Provided are a textile fabric sheet having stain and liquid resistance including a fabric sheet, a polyurethane coating layer formed on the fabric sheet and a silicon coating layer formed on the polyurethane coating layer and a method of preparing the same. Thus, a texture characteristic of the fabric substrate itself can be exhibited, and due to the polyurethane coating layer and the silicon coating layer stacked in two steps, excellent water resistance, stain resistance and air permeability can be exhibited. |

1. 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/m2, a curing agent and an organic solvent. |
