Abstract:
Hydroxymethylphosphine-ammonia and similar polymers, solubilized by hydroxymethylphosphonium salts and formaldehyde, were allowed to react with nitrogenous compounds such as urea, trimethylolmelamine and ammonia to (a) prepare flame-resistant polymers and (b) prepare flame-, glow-, wrinkle and shrink-resistant woven and knit textiles which contain 25% or more cellulosic fibers.
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.
Abstract:
The subject of the invention is a process for the manufacture of water-soluble condensation products of hydroxymethylphosphonium compounds and thiourea or biuret, characterised in that (a) one mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 0.5 mol, preferably 0.1 to 0.3 mol, of optionally methylolated thiourea or biuret at 40.degree. to 120.degree.C, optionally in the presence of formaldehyde or a formaldehyde-releasing agent and optionally in the presence of an inert organic solvent, the condensation is optionally thereafter continued at temperatures of 100.degree. to 150.degree.C and, if appropriate, free hydroxyl groups are etherified at least partially with at least one alkanol with 1 to 4 carbon atoms and, if appropriate, the salts of the condensation products are converted into the corresponding hydroxides. In addition to the preferred molar ratio range of 1:0.1 to 0.3, the range of 0.2 to 0.5 is also advantageous.The condensation products are used for flameproofing organic fibre material, especially textiles.
Abstract:
The subject of the invention is a process for the manufacture of condensation products of hydroxymethylphosphonium compounds and guanidines, characterised in that (a) 1 mol of a tetrakis(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 0.5 mol, preferably 0.1 to 0.3 mol, of guanidine, guanidine salt, guanylurea, guanylurea salt or methylolated guanidine or guanylurea at 40* to 120*C, optionally in the presence of formaldehyde or a formaldehyde-donating agent and optionally in the presence of an inert organic solvent, optionally subsequently further condensed at temperatures of 100* to 150*C and, if appropriate, free hydroxyl groups are at least partially etherified with at least one alkanol with 1 to 4 carbon atoms and if appropriate the salts of the condensation products are converted into the corresponding hydroxides. The condensation products are used for flameproofing organic fibre material, especially textiles.

The invention also includes method of rendering the resin article fireproof with said composition.
Abstract:
METHYLOL PHOSPHINE, METHYLOL PHOSPHINES IN COMBINATION WITH NITROGENOUS COMPOUNDS OR WATER SOLUBLE ADDUCTS OF THE PHOSPHINE AND NITROGENOUS COMPOUNDS ARE USED TO TREAT ORGANIC FIBROUS DERIVATIVES CONTAINING PRIMARY AND/OR SECONDARY AMINO GROUPS SUCH AS WOOL, LEATHER, NYLON AND AMINIZED COTTONS, ETC., TO PRODUCE FIBROUS DERIVATIVES WHICH ARE FLOW-, WRINKLE-, ROT- AND SHRINK-RESISTANT.
Abstract:
A flame resistant textile is provided. The textile is a sateen weave fabric containing cellulosic fibers, where the sateen weave fabric has a thickness of at least 19.5 mils, a thickness of at least 25 mils after 3 home washes at 120° F., an air permeability of at least 60 cfm, and a weight of less than about 7 oz/yd2. The sateen weave fabric also contains a treatment, where the treatment contains a tetramethylhydroxy phosphonium salt or its condensate and chemical selected from the group consisting of urea, guanidines, guanyl urea, glycoluril, and polyamines. When the sateen weave fabric to which the treatment has been applied has been heat-cured and oxidized at least a portion of the cellulosic fibers have a pentavalent phosphate compound polymerized therein. The method for producing the flame resistant textile is also provided.
