IMPROVED JOINT STRUCTURE OF WATERPROOFED CLOTH |
| 摘要 |
An improved joining structure for a waterproof fabric composed of a base fabric with a soft (elastomeric) resin film adhered thereon is provided. The joining structure is formed in a welt seam in which a hot-melt resin adhesive layer is interposed as a part of intermediate layers of the structure. The joining structure has properties of (1) bond strength >/= 25 kg/25 cm width, (2) bending stiffness </= 20 gf.cm<2>/cm and (3) water resistance after rubbing 1,000 times according to Scott shape method >/= 800 mm H2O. The joining structure can be formed by a method including joining the waterproof fabrics to form a welt seam with a hot melt resin layer put between and following that applying a high-frequency welding to the welt seam portion at a condition with an insulating elastic sheet interposed between the welt seam portion and electrode means to cause the hot-melt resin to be melted. <IMAGE> |
