    Abstract: Cellulosic fabric is dyed by affixing a hydroxymethyl phosphonium-nitrogen based polymer to the fabric and thereafter dyeing it with a cotton dye having anionic groups, in an acidic or neutral environment. In addition, a new method of affixing the polymer to the fabric is provided comprising contacting the fabric with a solution of urea and a precondensate of urea and tetrakis hydroxymethyl phosphonium salt.

    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.
