Title:
METHOD OF BONDING WATERPROOF FABRICS
Document Type and Number:
WIPO Patent Application WO/2000/009795
Kind Code:
A1
Abstract:
A method of bonding waterproof fabrics comprising the steps of disposing a hot melt resin bonding material layer between the waterproof fabrics, waterproofed with a resin film, sewing them together, clamping the sewn portion between a set of metal electrodes curved in an arcuate form, and fusing the hot melt resin adhesive by radio frequency heating to bond the fabrics. This bonding method can uniformly bond the sewn portion even when the sewn portion is curved within a plane or is curved three-dimensionally or the thickness of the sewn portion is partially different, such as a collar stitching portion, a sleeve stitching portion, a crotch portion of clothes, and can impart excellent waterproofness to the overall sewn portion. Further, the sewn portion of a sewn article has high bonding strength but does not become rigid.
