IPC: D06M15/263
Filed: 1952-10-14
Abstract: Compositions for the production of moistureproof coatings, impregnations, prints or dyeings on fibrous materials comprise aqueous dispersions of polymers containing both halogen and acid amide groups, hardenable initial condensation products of thermosetting resins and, if desired, hardening agents and/or pigments.  Suitable polymers are copolymers of acrylamide and vinyl chloride or as-dichlorethylene; methacrylamide and a -chloracrylic acid esters, vinyl-b -chlorethyl ether or acrylic or methacrylic acid-b -chlorethyl ester.  The copolymers may also contain styrene, butadiene or acrylates.  Mixtures of acrylonitrile-as-dichlorethylene and acrylamide-ethyl acrylate copolymers may also be used.  Suitable condensation products are those of formaldehyde and urea, thiourea, alkylated ureas, acetylene diurea, melamine, dicyandiamide, guanidine, urethanes, diurethanes, glyoxal monourein and phenol, or methylol ethers. The dispersions may also contain emulsions of benzine, xylene, toluene or trichlorethylene, softeners, protective colloids, fillers, waterproofing and flameproofing agents.  Examples describe the use of aqueous dispersions of (1) a copolymer of b -chlorethyl acrylate, methyl acrylate and acrylamide containing ammonia, tetramethylol-acetylene diurea, trimethylolmelamine or dimethylol urea, ammonium polyacrylate and nitrate and the azo dyestuff from 2 mols of diazotized 2.4-dichloraniline coupled with diaceto-acetyl-3.31-tolidine; (2) a copolymer of as-dichlorethylene, butyl acrylate and acrylamide, ammonia, gum tragacanth, dimethylol-1.4-butanediol diurethane, ammonium nitrate, white spirit and copper phthalocyanine paste; (3) a copolymer of vinyl chloride, methyl and butyl acrylates and acrylamide, ammonia, gum tragacanth, glycerine, trimethylol melamine, ammonium thiocyanate, white spirit and aluminium powder wetted with an oleyl alcohol-ethylene oxide reaction product; (4) a copolymer of vinyl chloride, butyl acrylate and methacrylamide, methyl cellulose, a formaldehyde-glyoxal monourein condensate, ammonia, ammonium sulphate, trichlorethylene and copper phthalocyanine paste; (5) a copolymer of b -chlorethyl methacrylate, propyl acrylate and acrylamide, sodium alginate, formaldehydemelamine condensate, ammonium nitrate and iron oxide; (6) a copolymer of vinyl-b -chlorethylether and methyl acrylate, a copolymer of butyl acrylate, acrylonitrile and acrylamide, sodium pectinate, dimethylol-dimethyl urea, ammonia, ammonium nitrate, gasoline and the pigment of (1); (7) a copolymer of as-dichlorethylene, acrylonitrile and propyl acrylate, a copolymer of vinyl chloride, butyl acrylate and methacrylamide, sodium polyacrylate, bismethyl ether of tetramethylolmelamine, tartaric acid, xylene, ammonia and copper phthalocyanine paste. The compositions may be applied to fibres of natural or regenerated cellulose, cellulose acetate, polyamide, polyacrylonitrile, polyesters, wool, silk or leather, dried at 50 DEG  to 100 DEG  C. and then heated, e.g. at 100 DEG  to 200 DEG  C.ALSO:Compositions for the production of moistureproof coatings, impregnations, prints or dyeings on fibrous materials comprise aqueous dispersions of polymers containing both halogen and acid amide groups, hardenable initial condensation products of thermo-setting resins and, if desired, hardening agents and/or pigments.
