Abstract
A method of evaporative cooling using sorbent sheet materials comprising a fibrous web that includes entangled fibers and a solid high sorbency liquid-sorbent polymeric material is disclosed. A sorbent sheet material useful for administering cold water therapy is also described.
Claims21
A method of evaporative cooling comprising
- (a) wetting a sorbent sheet material comprising a web comprising fibers having an average diameter of about 1-20 microns and a solid high-sorbency liquid-sorbent polymeric material contained within said web with a liquid for which said polymeric material exhibits high-sorbency;
- (b) placing said wetted sorbent sheet material in contact with the object to be cooled;
- and
- (c) allowing said liquid contained in said wetted sorbent sheet material to evaporate while said wetted sheet material is in contact with the object to be cooled to provide a cooling effect on said object.
