  • Method for converting and maintaining a fabric material in a fire retardant, heat resistant state
    Patent number: 4686109
    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.
