ABSTRACT:
Flame resistance is imparted to cellulosic textiles by the application of compositions prepared by reacting phosphonic acid derivatives with ammonia or appropriate amine compounds. Textile compositions thusly obtained exhibit levels of flame resistance which remain essentially unchanged after 50 or more launderings. A comparison of textiles containing the instant compositions to textiles containing prior art flame retardants using verticle flammability tests, reveals that flame resistant textiles of the invention required one half or less of the amount of added compositions to pass the test as did prior art textiles.
