Abstract
A process for printing textile materials consisting of cellulosic fibers, or of blends of cellulosic fibers and synthetic fibers, using a print paste which contains a synthetic thickener and a disperse dye, with or without conventional assistants, and, per 1,000 parts by weight of print paste, from 40 to 250 parts by weight of an N-methylol compound or N-methylol-ether compound of urea, of a urea derivative or of a carbamic acid ester, the print being fixed at an elevated temperature. The resulting prints have exceptionally good washfastness.
Claims8
A process for printing textile materials consisting of cellulose fibers or mixtures thereof with synthetic fibers, comprising:
- formulating a print paste consisting essentially of a synthetic thickening agent which is a homopolymer or copolymer of an ethylenically unsaturated carboxylic acid of 3 to 5 carbon atoms, a disperse dye, a fixing agent and auxiliaries, said formulation containing from 40 to 250 parts by weight of a fixing agent selected from the group consisting of N-methylol compounds of urea and urea derivatives, N-methylol ether compounds of urea and urea derivatives, and N-methylol and N-methylol ether compounds of carbamic acid esters per 1000 parts by weight of said print paste;
- applying said print paste to said textiles;
- and fixing said dye at an elevated temperature.
A print paste for printing textile materials, consisting essentially of:
- a synthetic thickening agent, a disperse dye and from 40 to 250 parts by weight of a compound selected from the group consisting of N-methylol compounds of urea and urea derivatives, N-methylol ether compounds of urea and urea derivatives, and N-methylol and N-methylol ether compounds of carbamic acid esters per 1000 parts by weight of said print paste.
A process for printing textile materials consisting of cellulose fibers or mixtures thereof with synthetic fibers, comprising:
- formulating a print paste consisting essentially of a synthetic thickening agent which is a homopolymer or copolymer of 3 to 5 carbon atoms, a disperse dye, a fixing agent and optionally at least one assistant selected from the group consisting of emulsifiers, dispersants, levelling agents, pH regulators, fixing accelerators, anti-foam agents, oxidizing agents and reducing agents, said formulation containing from 40 to 250 parts by weight of a fixing agent selected from the group consisting of N-methylol compounds of urea and urea derivatives, N-methylol ether compounds of urea and urea derivatives, and N-methylol and N-methylol ether compounds of carbamic acid esters per 1000 parts by weight of said print paste;
- and
- applying said print paste to said textiles;
- and
- fixing said dye at an elevated temperature.
