Abstract
A method of disposing of garments after use. The garments, linens, drapes, towels and other useful articles are provided as woven, non-woven, knitted or otherwise formed fabric of thermoplastic polyvinyl alcohol polymer fiber, the fiber being water soluble only at temperatures above approximately 37 °C and preferably above 50 °C. After use, the fabric is subjected to water at a sufficient temperature to substantially dissolve the fabric whereupon the water and dissolved fabric are subjected to disposal.
