Down products having bonding pattern lines formed by high-frequency bonding technique and Preparation thereof

摘要

According to the present invention, the heat-reactive adhesive liquid is printed and dried on the inner surface of the lining and / or the outer surface or on the reinforcing member in a predetermined printing pattern, and after the lining, the reinforcing member, The reinforcing member and the outer cloth are bonded together by an adhesive liquid so that the down product formed with the pattern bonding line for dividing the compartment can be manufactured without forming the sewing hole and without damaging the fabric.INDUSTRIAL APPLICABILITY According to the present invention, since a high-frequency bonding method using a heat-sensitive adhesive and / or a dividing line is first formed to produce a double fabric, and a post-bonding post-cutting method is used, internal joining lines having excellent adhesion and durability, It is possible to manufacture a down product having an excellent finish quality and having an aesthetically excellent surface pattern line integrated with a bonding pattern line, and mass production of down products by mechanization and automation.;
