AbstractA composite fabric and its method of disposal after use. Garments, linens, drapes, towels and other useful articles are provided as the composite of a reusable first component and a woven, non-woven, knitted or otherwise formed fabric of thermoplastic polyvinyl alcohol polymer as a second component. The second component is water soluble in temperatures above approximately 140° F. After use, the composite is subjected to water of sufficient temperature to substantially dissolve the thermoplastic polyvinyl alcohol component but not the reusable first component.
