Title: Improvements in or relating to methods of printing or colouring textile fabrics and the textile colouring composition used in said method
IPC: D06P1/44
Filed: 1948-04-15
Abstract: Textile fabrics are printed or coloured by treating them with an aqueous suspension of a pigment and an ammonium or amine salt of a copolymer of styrene, methyl-, butyl- or chlorostyrene, with maleic anhydride or a partial ester of a maleic acid, such as a half ester of isopropyl or secondary butyl maleate, and then heating to 200 DEG to 325 DEG  F.  The copolymers may include minor amounts of vinyl acetate, vinyl chloride, vinyl ethyl ether, indene, vinyl methyl ketone and acrylic esters, and the salts may be those of ammonia, guanidine, methyl-, butyl- or amyl-amines, and phenyl or benzyl tri-methyl ammonium hydroxide. Formaldehyde, paraformaldehyde, trioxane, melamine- or urea-formaldehyde resins or their methyl, ethyl, or butyl ether derivatives, e.g. the tetra-methyl ether of tetra-1-methylol melamine, or mixtures thereof may be added to the suspension in small amounts, e.g. 10-20 per cent, or the fabric may be after-treated with a dilute aqueous solution of a heavy metal salt, e.g. copper, aluminium, calcium or zirconium chloride, acetate, or formate, in order to increase the permanency. Pigments used include red iron oxide, phthalocyanine green, a coupled paranitroorthotoluidine-orthotoluidide of b -oxynaphthoic acid compound, a mixed lead chromate-ferric ferrocyanide-basic lead carbonate pigment, a reduced phosphotungstic lake green, carbon black, ferric oxide, lead carbonate or chromate, ochre, carmine.  The fabrics may be of cotton, viscose, acetate or cuprammonium rayon, wool, nylon, glass, linen, flax, hemp, jute, ramie, silk, vinyl chloride-vinyl acetate copolymer.  Screen or roller printing, or a dipping process may be used, the latter being followed by padding, quetching or mangling before the heating stage.ALSO:Textile fabrics are printed or coloured by treating them with an aqueous suspension of a pigment and an ammonium or amine salt of a copolymer of styrene, methyl, butyl or chlorostyrene, with maleic anhydride or a partial ester of maleic acid, such as a half ester of isopropyl or secondary butyl maleate, and then heating to 200 DEG  to 325 DEG  F.

Formaldehyde, paraformaldehyde, trionane, melamine- or urea-formaldehyde resins or their methyl, ethyl or butyl ether derivatives, e.g. the tetramethyl ether of tetramethylol melamine or mixtures thereof may be added in small amounts, e.g. 10-70 per cent, to the suspension, or the fabric may be after-treated with a dilute aqueous solution of a heavy metal salt, e.g. copper, aluminium, calcium, or zirconium chloride, acetate, or formate, in order to increase the permanency.  Pigments used include red iron oxide, phthalocyanine green, or coupled paranitro ortho toluidine-ortho toluidide of b -oxynaphthoic acid compounds, a mixed lead chromate-ferric ferrocyanide-basic lead carbonate pigment, a reduced phospho-tungstic lake green, carbon black, ferric oxide, lead carbinate or chromate, ochre, and carmine.  Fabrics treated may be of cotton, viscose acetate or cuprammonium rayon, wool, nylon, glass, linen, flax, hemp, jute, ramie, silk, vinyl chloride-vinyl acetate copolymer, using the screen, roller printing, or dipping processes, the latter being followed by padding, quetching or mangling before the heating stage.
