A green water‐soluble cyclophosphazene as a flame retardant finish for textiles

Abstract

Poly and cyclophosphazenes are excellent flame retardants but currently, are not used as textile finishing agents because watersoluble and permanent washing systems are missing. Here, we demonstrate for the first time, the successful usage of a watersoluble cyclotriphosphazene derivative for textile finishing for cotton, different cotton/polyester, and cotton/polyamide blend fabrics. A durable finish was achieved using a photoinduced grafting reaction. The flame retardant properties of the various fabrics were improved with a higher limiting oxygen index, a reduced heat release rate, and an exhibition of intumescent. Furthermore, the finished textiles passed several standardized flammability tests.
