ABSTRACT:
A method for converting and maintaining a fabric material in a fire retardant state through the steps of integrating a substantially non-toxic hydrophilic substance amidst the fibers of a fabric material where the hydrophilic substance is possessed of reversible hydration characteristics towards absorbing water in a non-heat or fire environment and alternatively releasing water in a heat or fire environment. The hydrophilic material is further capable of being reversibly restored to a further fire retardancy after the alternative release of water in a heat-fire environment. The steps embodied by the method include hydrating the incorporated hydrophilic material to a desired level of hydration at equilibrium in which the fire retardant material preferably comprises a hydrogel substance which not only releases at a "safe", relatively low, triggering temperature, with a substantially high water retention capability--to reduce or eliminate the ability of such a treated fabric to sustain a flame or high levels of heat, in which the fire retardant itself is a poly (acrylic acid), poly (ethylene oxide) or carbox (polyethylene oxide (PEO)) methyl cellulose compound or the like.
