<P>PROBLEM TO BE SOLVED: To provide a cooling sheet material capable of repeatedly performing cooling by being impregnated in water for the time of use. <P>SOLUTION: The cooling sheet material (10) is constituted of: a moisture adsorptive and desorptive sheet (11) which has a continuous pore structure and is cooled by vaporization heat of moisture; a moisture assisting sheet (12) which is laminated on one surface of the moisture adsorptive and desorptive sheet, and replenishes moisture to the moisture adsorptive and desorptive sheet; and a moisture adsorptive sheet (13) which is laminated on the other surface of the water assisting sheet and adsorbs humidity of a contact surface. The moisture adsorptive and desorptive sheet is constituted of sponge or nonwoven fabric made of a polyvinyl alcohol resin, the moisture assisting sheet is constituted of the nonwoven fabric of nylon resin fibers and/or polyester resin fibers, and the moisture adsorptive sheet is constituted of woven fabric of the nylon resin fibers and/or the polyester resin fibers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
