1,253,513. Emulsion for textile treatment. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 Dec., 1968 [1 Jan., 1968], No. 119/68. Heading B1V. [Also in Divisions C3 and Dl] An emulsion used in the treatment of cellulosic textile materials comprises a halogenated hydrocarbon solvent, water, a resin precondensate which is an initial-stage condensation product of formaldehyde with a nitrogen containing compound or an alkyl ether thereof in which the alkyl group contains 1-4 carbon atoms which is selfcuring under acid conditions and/or is capable of reacting with the hydroxyl groups present in the cellulosic textile material, and a catalyst which is an acid or acid-generating substance. The emulsion may contain as emulsifying agent, e.g. ethylene glycol dioleate, an amine salt of a long chain fatty acid and butyl carbitol, the isopropylamine salt or dodecyl benzene sulphonic acid, sortitan, mono oleate or a mixture of sulphated cetyl/oleyl alcohols. The resin precondensate may be a condensation product of formaldehyde with urea, thiourea, dicyan-diamide, an amide, carbamate, aminotriazine, uron, urein, ureides, imidazolidinone pyrimidone or triozane or alkyl ether thereof, the catalyst may be monochloracetic acid, dodecyl benzene sulphonic acid, 2, 2-bis (hydroxymethyl) butyl phosphonic acid, magnesium chloride, zinc nitrate, methyl ptoluene sulphonate, cetyl pyridinium bromide or stearamidomethylpyridinium chloride and the halogenated hydrocarbon solvent may be trichloroethylene, perchloroethylene, 1, 1, 1- trichloroethane or 1, 1, 2-trichloro-1, 2, 2-trifluoroethane. The emulsion may also contain lubricants and softeners, e.g. low molecular weight polyethylene waxes, water repellents, e.g. silicones, methylol stearamides and stearamidomethyl pyridinium chlorides, and stiffening agents, e.g. polyvinyl acetate.
