ABSTRACT:
Novel phosphonic acid salts produced from ethane- or methanephosphonic acid, dicyandiamide and/or guanidine and optionally ammonia and corresponding to the formula ##STR1## wherein n, p, q, t and y are each 1 or 2, are particularly suitable for fireproofing organic fibre materials. Synthetic and/or cellulose-containing fibre materials are treated with an aqueous solution of the phosphonic acid salts and are then dried preferably at 60.degree. to 200.degree. C. The applied phosphonic acid salts impair only negligibly the textile-mechanical properties of the treated fibre materials, especially of the cellulose-containing fibre materials dried at 120.degree. to 150.degree. C.
