LEAKPROOF SEAMS FOR NON-CONTAINABLE WATERPROOF/BREATHABLE FABRIC COMPOSITES

摘要

A prefabricated multi-layered flexible product which can be used as a liner for an outer shell or as a stand-alone product. A substrate fabric material is placed in parallel with a synthetic film membrane to form a two ply laminate with excess membrane at an edge thereof. A pair of the laminates are overlaid with the substrate fabrics opposing each other with the fabric edges aligned, and a thermoplastic film is strategically placed in between the layers to enhance bonding between the fabric layers and the excess membranes. The laminate(s) and/or separate sheets of above materials are assembled by using a radio frequency welding process and then out into two or three dimensional forms, which in their bonded state form either a prefabricated component liner or a prefabricated stand-alone product. The form may be a glove, sock, shirt, boot/shoe, hat, jacket, pant, etc.
