ABSTRACT:
A liquid proof seam construction is provided. A double needle flat-felled seam is constructed having a melt adhesive polymer film disposed within the seam. The seam is then passed through a hot air/pressure device which melts the film and compresses the seam. This forms a liquid, e.g. waterproof, bond between adjacent layers of material and also fills up any area around the stitching formed by needle holes.
