Title: Innovations in Fire Retardant Fabrics by Marshall W. Duke
Introduction
Marshall W. Duke is an accomplished inventor based in Aiken, South Carolina. He has made significant contributions to the field of fire retardant fabrics, holding two patents that showcase his innovative methods. His work focuses on enhancing the safety and performance of cellulose and cellulose-containing fabrics.
Latest Patents
Duke's latest patents include a process for rendering cellulose and cellulose-containing fabrics fire resistant. The first patent describes a method that involves impregnating the fibers with a solution of an aminoplast resin, an acid, and a dialkyl phosphono methylol alkylamide. This process results in a fabric that possesses high fire-retardancy values, a soft hand, and tensile values similar to that of untreated fabric. The second patent outlines a similar process, where the fibers are first treated with an aminoplast resin and then with tetrakis (hydroxymethyl) phosphonium hydroxide. This method also yields a fabric with excellent fire-retardancy properties.
