Abstract
A process is provided for flameproofing cellulosics in which an aqueous solution is applied thereto which contains PA0 (A) the phosphorinane of the formula ##STR1## (B) an aminoplast precondensate, e.g. a methylolmelamine, and, optionally, (C) a latent acid catalyst, e.g. 2-amino-2-methyl-1-propanolchloride. The cellulosics, e.g. textiles containing natural or regenerated cellulose, are then dried up to 100.degree. C. and subjected to a heat treatment above 100.degree. C., e.g. at 130.degree. to 200.degree. C.
