Abstract
Flame-retardant acrylic filaments containing a flame retardant which is the reaction product of a dibasic acid amide, an oxyacid of phosphorus and a polyhydroxy alcohol, the flame retardant being bound to the acrylic filaments by a cross-linking agent. The filaments are made flame-retardant by applying the flame retardant and cross-linking agent to the filaments and subsequently heating the filaments to chemically bind the flame retardant to the acrylic filaments.
