A process for rendering cellulose and cellulose containing fabrics fire resistant by first impregnating the fibers with a solution of an aminoplast resin, an acid and an effective amount of a dialkyl phosphono methylol alkylamide to produce fire retardancy in the resulting fabric having the formula ##STR1## wherein R is lower alkyl having 1 to 6 carbon atoms and x is an integer from 1 to 3 and polymerizing the resin while the fibers are wet and swollen. The fabric is then cured, washed and dried. The fabric obtained from this process possesses high fire-retardancy values, soft hand, and tensile values similar to that of the untreated fabric.

Fire retardant fabrics and method for preparation thereof

A process for rendering cellulose and cellulose containing fabrics fire resistant by first impregnating the fibers with an aminoplast resin and polymerizing the resin while the fibers are wet and swollen. Thereafter, the fabric is impregnated with tetrakis (hydroxymethyl) phosphonium hydroxide, cured, washed and dried. The fabric obtained from this process possesses high fire-retardency values, soft hand, and tensile values similar to that of the untreated fabric.
