Abstract

A garment sealing tape or patch may be used to waterproof seams of or repair discontinuities in a wide variety of garments or other products, such as surgeon's gowns and firefighter's turnout coats, in a simple, inexpensive and long lasting manner with minimal smoke emission. The garment sealing tape or patch may include a first layer of a dimensionally stable heat reflecting film such as a polyurethane microporous film, and a second layer bonded to the first layer. The second layer is an uncured thermosetting polyurethane or polyester adhesive having a thickness between about 0.5-12 mils. The tape or patch may also comprise a third layer which is a fabric (such as a polyester tricot having a weight between about 0.7-2.5 ounces per square yard) adhesively bonded (e.g. by hot melt adhesive) to the heat reflecting surface of the film. The tape or patch may be applied by a laundry press or iron, or using an autoclave, to apply heat sufficient to thermoset the adhesive. The tape or patch may be constructed by applying an adhesive to a first surface of the film, mating the adhesive on the film with the fabric, pressing the mated film and fabric together to adhesively secure the film to the fabric, applying the seam sealing adhesive to a second surface of the film, and slitting or cutting the resulting laminate to produce a fabric tape ribbons or fabric repair patches.
