Abstract
527,834. Dyeing textiles. KODAK, Ltd. March 14, 1939, No. 8113. Convention date, March 14, 1938. [Classes 2 (ii), 2 (iii) and 15 (ii)] Cellulose esters or ethers, dyeing. - The fastness, especially to acid fading, of dyeings on textile materials made of or containing an organic derivative of cellulose is improved by treating the materials, before, during or after dyeing, with melamine or an N-substituted derivative thereof without substantial formation of resinous compounds or compounds of melamine or its derivatives with cellulose. Alternatively, the melamine or its derivative may be incorporated in the solution from which the fibres are spun. Specified N-derivatives of melamine are the monoacetyl-, monomethyl-, monoamyl-, monophenyl-, tributyl- and 2- acetyl-4-methyl-derivatives. Specified dyeings are those obtainable on cellulose acetate materials with the following dyestuffs, viz. : (a) the 1 : 4-di-methylamino-, 1 : 4-di-#-hydroxyethylamino-, 1 - amino - 4 - #- hydroxyethylamino -, 1 - hydroxy - 4 - methylamino -, 1 : 4 - diamino -, 1 - methylamino - 4 - p - aminophenylamino -, 1 - metbylamino - 4 - ethylamino -, 1 - methylamino - 4 - #- hydroxyethylamino - and 1 - # - hydroxyethylamino - 4 - p - aminophenylamino - derivatives of anthraquinone, (b) the azo dyestuffs, 2 : 4 - dinitro - 6 - bromoaniline # 1: 5 - aminonaphthol and 4 - nitro - 2 - chloroaniline# 1-#-hydroxyethylamino-5-naphthol, (c) the indophenols obtained by reaction of 2:4:6- trichlorophenol with 4-amino-3-methyl-N-dimethylaniline or of 2:4-dibromophenol with 4- amino-N-diethylaniline in presence of sodium chromate, (d) 2:5:8-tri-methylamino-1:4-naphthoquinone. In examples, (1) a cellulose acetate yarn or fabric is entered into a bath at 45- 55‹ C. containing a dispersion in soap solution of 1:4-di-methylamino anthraquinone which has been finely ground with soap or sodium oleylglyceryl sulphate, the temperature being gradually raised to 80-85‹ C. and so maintained for several hours with addition, if desired, of sodium chloride to exhaust the dyebath, whereupon the material is washed, soaped, rinsed, treated for three-quarters of an hour with an aqueous solution of melamine at 65‹ C. and dried to obtain a blue dyeing fast to acid fading and to light; (2) a cellulose acetate fabric similarly dyed with 1-methylamino-4-ethylamino-, 1-methylamino-4-#-hydroxyethylamino- or 1 - #- hydroxyethylamino - 4 - p - aminophenylamino-anthraquinone is similarly after-treated ; (3) and (4) a cellulose acetate fabric, dyed with the indophenol from (3) 2:4- dibromophenol and 4-amino-N-diethylaniline or (4) 2:4:6-trichlorophenol and 4-amino-3-methyl- N-dimethylaniline, is treated for one hour with an aqueous solution at 65‹ C. containing melamine and sodium carbonate and dried to obtain a blue-green dyeing fast to acid fading ; (5) a cellulose acetate fabric, dyed with 2:5:8-trimethylamino-1:4-naphthoquinone (cf. Specification 304,804, [Class 15 (ii)]), is similarly treated with melamine. Specification 243,841, [Class 15 (ii)], also is referred to. Monoacetylmelamine is obtained by acetylating melamine. Monomethyl-, monoamyl- and monophenylmelamines are obtained by heating cyanuryl chloride (1 mol.) with an aqueous solution of methylamine, amylamine or aniline (1 mol.) and heating the product with liquid ammonia (1 mol.) under pressure. Tributylmelamine is obtained by heating cyanuryl chloride (1 mol.) with butylamine (3 mols.) at 150‹ C. under pressure, if desired in presence of a solvent, e.g., water. 2-Acetyl-4-methylmelamine is obtained by reacting monomethylmelamine with acetic anhydride. Sodium oleylglyceryl sulphate is obtained by neutralizing with sodium carbonate or hydroxide the product of the reaction of chlorosulphonic acid or glyceryl trioleate.
