Abstract
A process is proposed for the fireproofing treatment of textile materials by impregnating them initially with a melamine-formaldehyde resin or organosilicon substances, and then with a solution of a complex compound of the ammonia salt of amidoalkylphosphonic acid with ammonium chloride. Materials treated in accordance with the invention have reduced combustibility and low toxicity of the gases given off during combustion.
