PVC COATING METHOD FOR DOUBLE WALL FABRICS HAVING DESIGN ON ITS SURFACE

摘要

PURPOSE: A PVC coating method for dual space paper with a pattern is provided to repeatedly perform PVC coating on the outside surfaces of first fabric and second fabric which are vertically arranged, thereby preventing air filled within the first fabric and the second fabric from being leaked to the outside. CONSTITUTION: A PVC coating method for dual space paper with a pattern comprises following steps. Dual space paper which includes first fabric arranged vertically, second fabric arranged vertically and a supporting member interposed between the first fabric and the second fabric is prepared (S310). A first PVC coating is performed by applying heat in order to form a first coating layer on the outside surfaces of the first fabric and the second fabric (S320). A second PVC coating is performed by applying heat in order to form a second coating layer on the first coating layer. The second PVC coating is performed at a higher temperature than that of the first PVC coating.
