Abstract
A durable, single or multi-use cooling garment is provided having a multilayer structure. The cooling garment includes an inner layer of a thermoplastic polymer material that is liquid impermeable and vapor permeable, an outer liquid permeable reinforcing layer such as a web of thermoplastic polymer fibers, and a central absorbent layer that contains a stabilized matrix of about 55% to 95% cellulosic fibers and from about 5% to 45% thermoplastic polymer fibers. The layers are bonded together and the absorbent layer is bonded to at least one of the other layers by regionally applying sufficient energy to the layers wherein the thermoplastic polymers melt and resolidify to form inter-fiber bonds. The cooling garment can be saturated with water or other liquids and provide the wearer with relief from the heat such as may be achieved by evaporative cooling.
