Inventor: GLENZ OSKAR
IPC: D04H1/587
Filed: 1964-05-27
Abstract: A flat textile element is treated (see Divisions B2 and D1) with an aqueous dispersion of a spontaneously cross-linking copolymer of a monomer (a) of the formula <FORM:1039877/C3/1> in which R represents H or methyl and X represents an organic radical bonded by way of N and containing at least one group of the formula <FORM:1039877/C3/2> wherein R1 represents an alkyl group, preferably with one to four carbon atoms.  The textile element may subsequently be heated to cross-link the polymer. The radical X may be the residue of melamine, urea, ethyleneurea propylenurea or acetylenebis-urea, that has been methylolated and the methylol groups then etherified.  The other monomer or monomers of the copolymers may belong to one or more of the following classes: (b) olefinically unsaturated compounds containing a carbonamide or a hydroxyl group, e.g. acrylamide, an ester of an acrylic acid with a polyhydric alcohol, or the corresponding derivatives of methacrylic acid; (c) compounds of the formula <FORM:1039877/C3/3> in which R represents H or methyl and R11 represents an alkyl radical of one to eight carbon atoms, or an acyl radical, e.g. acetyl, propionyl or benzoyl; (d) olefinically unsaturated monomers which, when polymerized alone yield soft, flexible polymers, such as alkyl esters of acrylic acid with one to twelve carbon atoms in the alkyl radical, alkyl esters of methacrylic acid with eight to twelve carbon atoms in the alkyl group, diolefines such as 1,3-butadiene or isoprene, or vinyl alkyl ethers in which the alkyl group contains one to four carbon atoms; and (e) polymerizable olefinic monomers which, when polymerized alone, yield hard, stiff polymers, e.g. styrene, substituted styrenes, acrylonitrile, methacrylonitrile, vinyl and vinylidene halides, alkyl methacrylates with one to four C atoms in the alkyl group, acrylic, methacrylic and itaconic acids and vinyl acetate and propionate.  In Examples (1)-(7), copolymers of ethyl acrylate, acrylamide and: <FORM:1039877/C3/4> (compound Ia), methacrylamide-N-methylol methylol methyl ether, <FORM:1039877/C3/5> are used.  In other Examples, copolymers are of:  (8) butyl acrylate, acrylamide and compound Ia; (9) butyl acrylate, acrylonitrile and compound Ia; (10) butyl acrylate, acrylonitrile, acrylamide and compound Ia; (11) butyl acrylate, acrylonitrile acrylic acid and compound Ia; (12) butyl acrylate, styrene, acrylamide and compound Ia; (13) butyl acrylate, vinyl acetate, and compound Ia; (14) ethyl acrylate, butyl acrylate, methyl methacrylate, acrylamide and compound Ia; (15) butyl acrylate, vinylidene chloride, acrylamide, acrylic acid and compound Ia; (16) butadiene, acrylonitrile, acrylamide, methacrylic acid and compound Ia; (17) butyl acrylate, polybutadiene, acrylamide and compound Ia; (18) ethyl acrylate, methacrylic acid and compound Ia; (19) isooctyl acrylate and compound Ia; and (20) butyl acrylate, styrene, acrylamide and compound Ia.ALSO:A flat textile element is treated with an aqueous dispersion of a spontaneously cross-linking copolymer of a monomer (a) of the formula: <FORM:1039877/B1-B2/1> in which R represents H or methyl and X represents an organic radical bonded by way of N and containing at least one group of the formula <FORM:1039877/B1-B2/2> , wherein R1 represents an alkyl group, preferably with one to four carbon atoms.  The textile element may subsequently be heated to cross-link the polymer.  The expression "treatment of flat textile elements" includes the coating of textiles.  The radical X may be the residue of melamine, urea, ethyleneurea, propylenurea or acetylene-bis-urea, that has been methylolated and the methylol groups then etherified.  The other monomer or monomers of the copolymer may belong to one or more of the following classes: (b) olefinically unsaturated compounds containing a carbonamide or a hydroxyl group, e.g. acrylamide, an ester of a acrylic acid with a polyhydric alcohol, or the corresponding derivatives of methacrylic acid; (c) compounds of the formula: <FORM:1039877/B1-B2/3> in which R represents H or methyl and R11 represents an alkyl radical of one to eight carbon atoms, or an acyl radical, e.g. acetyl, propionyl or benzoyl; (d) olefinically unsaturated monomers which, when polymerized alone, yield soft, flexible polymers, such as alkyl esters of acrylic acid with one to twelve carbon atoms in the alkyl radical, alkyl esters of methacrylic acid with eight to twelve carbon atoms in the alkyl group, diolefines such as 1, 3-butadiene or isoprene, or vinyl alkyl ethers in which the alkyl group contains one to four carbon atoms; and (e) polymerizable olefinic monomers which, when polymerized alone, yield hard, stiff polymers, e.g. styrene, substituted styrenes, acrylonitrile, methacrylonitrile, vinyl and vinylidene halides, alkyl methacrylates with one to four C atoms in the alkyl group, acrylic, methacrylic and itaconic acids and vinyl acetate and propionate.ALSO:A flat textile element is treated with an aqueous dispersion of a spontaneously cross-linking copolymer of a monomer (a) of the formula <FORM:1039877/D1-D2/1> in which R represents H or methyl and X represents an organic radical bonded by way of N and containing at least one group of the formula <FORM:1039877/D1-D2/2> , wherein R1 represents an alkyl group, preferably with one to four carbon atoms.  The textile element may subsequently be heated to cross-link the polymer.  The expression "treatment of flat textile elements" includes the impregnation or spraying of fibre fleeces to bind and consolidate them into non-woven textiles, and the impregnation of woven fabrics to improve their texture or to provide a crease-resistant finish.  The radical X may be the residue of melamine, urea, ethyleneurea, propylenurea or acetylene-bis-urea, that has been methylolated and the methylol groups then etherified. The other monomer or monomers of the copolymer may belong to one or more of the following classes: (b) olefinically unsaturated compounds containing a carbonamide or a hydroxyl group, e.g. acrylamide, an ester of a acrylic acid with a polyhydric alcohol, or the corresponding derivatives of methacrylic acid; (c) compounds of the formula <FORM:1039877/D1-D2/3> in which R represents H or methyl and R11 represents an alkyl radical of one to eight carbon atoms, or an acyl radical, e.g. acetyl, propionyl or benzoyl; (d) olefinically unsaturated monomers which, when polymerized alone, yield soft, flexible polymers, such as alkyl esters of acrylic acid with one to twelve carbon atoms in the alkyl radical, alkyl esters of methacrylic acid with eight to twelve carbon atoms in the alkyl group, diolefines such as 1, 3-buadiene or isoprene, or vinyl alkyl ethers in which the alkyl group contains one to four carbon atoms; and (e) polymerizable olefinic monomers which, when polymerized alone, yield hard, stiff polymers, e.g. styrene, substituted styrenes, acrylonitrile, methacrylonitrile, vinyl and vinylidene halides, alkyl methacrylates with one to four C atoms in the alkyl group, acrylic, methacrylic and itaconic acids and vinyl acetate and propionate.  In the Examples, these copolymers are used to bond fibrous fleeces of cuprammonium rayon of nylon 6 and of a mixture of these two fibres.
