  • Patent number: 4067687
    Abstract: Textile treating compositions containing the elements phosphorus, nitrogen, and bromine and the processes for imparting flame resistance to organic fibrous materials have been prepared. This is accomplished by impregnating the textile treating compositions consisting of (1) tris(hydroxymethyl)phosphine mixed with nitrogenous compounds containing at least two members of the group hydrogen and methylol radicals (--CH.sub.2 OH) attached to trivalent nitrogen atoms, or (2) soluble methylol phosphine adducts which contain one or more methylol phosphine radicals (P--CH.sub.2 OH) prepared by reacting tris(hydroxymethyl)phosphine with an amide or amine which contains one or more hydrogens attached to a trivalent nitrogen with an organic bromine containing material with at least 10% bromine in the form of bromine atoms attached to carbon atoms, in proportions selected so that generally the phosphorus contained in structures of the group (--CH.sub.2).sub.

  • Patent number: 4006274
    Abstract: 2,4,6-Tris(carbamoylmethylamino)-1,3,5-s-triazine, abbreviated TCMT, is prepared by the reaction of 2,4,6-tris(carbethoxymethylamino)-1,3,5-s-triazine with ammonia. The methylol derivative of TCMT is prepared and applied to cotton textiles and blends of cotton and polyester to impart wrinkle recovery thereto.

  • Patent number: 3987098
    Abstract: Novel quaternary arylaminoalkyl phosphonium salts having the formula [(ArNHCHR).sub.4 P].sup.+X.sup.-, where R is a radical selected from the group consisting of hydrogen, alkyl and aryl, Ar is aryl, and X is halogen, are prepared by the reaction of primary aromatic amines with quaternary hydroxyalkyl phosphonium salts having the formula [(HOCHR).sub.4 P].sup.+X.sup.-, where R and X are similarly defined. The compounds of this invention are useful as flame retardant for cotton, plasticizers, lubricant additives, and surface-active agents.

    Inventors: Arlen W. Frank, George L. Drake, Jr.
  • Patent number: 3979533
    Abstract: Derivatives of dicarboxylic acids containing a phosphono group in the alpha and alpha prime position have been made. These have a wide variety of uses as intermediates. Specifically, one of the new compounds is useful in imparting wrinkle resistance as well as flame retardance to cellulosic textiles.

  • Patent number: 3949108
    Abstract: Organic fibrous materials especially cellulosic and other textiles are rendered flame resistant upon treatment with an emulsion containing either (1) an organic bromine containing material having at least 65% bromine such as polyvinylbromide, (2) polyvinylbromide and an N-methylol agent such as trimethylolmethylglycoluril, (3) polyvinylbromide and a metal oxide such as antimony oxide, and (4) polyvinylbromide, N-methylol agent and metal oxide. The emulsions are applied to various fibers by the pad-dry-cure technique. The finish contained the added quality of wrinkle resistance and rot resistance. The treated textiles, including polyester/cotton blends remain highly flame resistant through innumerable laundry cycles.

  • Patent number: T100601
    Abstract: The tetramethylol derivatives of 2,4-diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine, namely: 2,4-bis[di(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-bis[di(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazin e, respectively, were used in combination with colloidal antimony oxides and or water emulsifying agents and suitable solvent to impart durable flame-retardancy to cellulosic materials, protein fibers such as wool, and to blends of cellulosic materials and synthetic fibers, particularly to cotton textiles or textiles composed of blends of cotton and polyester. Afterglow was eliminated by the use of small amounts of reactive phosphorus compounds.
