Abstract
A garment has a particular stitched seam that very effectively cooperates with a seam sealing tape to provide an effective and long lasting seal at the seam. First and second portions of the fabric are joined together by a stitched seam comprising a 300 class stitch with Top stitch, using about Tex 30 or smaller thread, and the seam sealing tape seals the stitched seam. The thread may comprise a polyester continuous filament sewing thread size Tex 30-10, with about 8-10 stitches per inch. The 300 class stitch may comprise a plain stitch, and the stitched seam may comprise a superimposed seam. The seam is readily produced using either a Single or Double Lockstitch Machine which contains one or two needles, one or two hooks, and one or two bobbins, respectively. The sealing tape may comprise a first layer of a dimensionally stable heat reflecting film having a heat reflecting surface, a second layer bonded to the first layer and comprising an uncured thermosetting polyurethane or polyester adhesive having a thickness between about 0.5 to 12 mils, and a fabric adhesively bonded to the heat reflecting surface.
