Abstract
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.
