10 m min the drying apparatus typically works as a thermal drying manner and a thermal drying temperature is typically at a range of about 80 degrees celsius u00b0 c to 200 u00b0 c when the gravure roll 104 rotates the coating solution 112 in the tank 102 is brought to bumps on the surface of the gravure roll 104 and then is coated on a surface of the textile 114 at a pressing point between the gravure roll 104 and the pressure roller 106 typically the size of the bump on the surface of the gravure roll 104 is in a range of about 40 mesh per square inch mesh in 2 to 200 mesh in 2 and preferably in a range of about 40 mesh in 2 to 180 mesh in 2 a pressure between the gravure roll 104 and the pressure roller 106 is 2 kilograms weight per square centimeter kgw cm 2 or less a viscosity of the spreading solution 112 is not limited herein however preferably in a range of 10 centipoises cps to 10000 cps and more preferably in a range of 200 cps to 5000 cps a weight of the polymer composition with the reactive groups which is brought onto the surface of the textile 114 by the coating solution 112 is less than 100 g m 2 actually by applying the gravure coating manner disclosed by the present invention the weight.
