HOT CLOTH

PURPOSE:To hold a bonded part to a dry state and to effectively heat a local place by bonding a water absorbing material to the single surface of a polymer film or that of the metal vapor deposition surfaces of the polymer film having metal vapor-deposited on both surfaces thereof and bonding heat-insulating cloth to the surface opposite to the water absorbing material bonded surface. CONSTITUTION:Water absorbing materials 4 are bonded to the single surface of a flexible polymer film 1 having an aluminum vapor deposition film 2 in a scattered state and a protective film composed of a polyester nonwoven fabric for pressing the water absorbing materials 4 is bonded to the surfaces of said water absorbing materials 4. A heat insulating material composed of flannel is bonded to the entire surface opposite to the surface having the water absorbing materials 4 bonded thereto. As the material quality of the vapor deposition film, aluminum is used but other corrosion-resistant metal such as chromium may be used. As the water absorbing materials, a saponified substance of a vinyl acetate/methyl acrylate copolymer is used and, as the material quality thereof, a molded body of a mixture consisting of a water-absorbable polymer material and pulp is used.
