Next, 50kg of polyurethane resin (Fine Chemical 1150, Fine Chemical Co., Ltd.), 20 kg of polyurethane adhesion promoter (Fine Chemical 1145, Fine Chemical Co., Ltd.), 30 kg of toluene and crosslinking agent (Dongsung Chemical 575, Dongsung Co., Ltd.) Chemical preparation) 3kg is mixed to prepare a polyurethane coating composition. The prepared polyurethane coating composition is contained in the first chamber and the second chamber and then coated in the primary chamber at 150 ° C., and then coated in the secondary chamber at 145 ° C., at a rate of 30 g / m 2 at a speed of 30 to 35 m / min. The fabric was coated three times. Physical properties of the fabric produced are shown in Table 1 below.
