Enzyme-dispersible bandage
Abstract
Abstract A readily disposable, multi-ply pad for contacting the body and absorbing body wastes consists of multiple plys of non-woven, fibrous material of good dry- and wet-strength, wet-strength being conferred on the materials by a binder which is essentially unaffected over periods of serveral hours or more by aqueous body wastes, but which is rapidly degraded by exposure to aqueous media containing enzymes; one or moreof the interior plys can be plain, untreated, non-woven fibrous material in the form of an absorbent pad; the whole pad being readily dispersed and disposable in domestic waste disposal systems by the addition of enzyme to the disposal receptacle together with the used pad, and such disposal having the advantage that even long-continued disposal of numerous pads has little or no deleterious effect upon domestic disposal systems.
