Abstract
A process for effecting flame retardation of fibrous structures, such as fabrics, particularly fabrics made from mixtures of natural and synthetic fibers, such as cotton and nylon. The process includes the steps of contacting the fabric to be treated with halomonomers and/or inorganic salts, followed by fluorocarbon grafting, and then by photohalogenation. The aforesaid treatment results in fabrics which are not only flame resistant but also have improved hand, manifested by softness, silkiness, and unwettability of the resulting fabric.
