Abstract
Condensation products of formaldehyde with aminotriazines are used in the production of dyed and printed materials. The aminotriazines specified are melam, 2 : 4 : 6-triamino-1 : 3 : 5 - triazine, 2 - chloro - 4 : 6 - diamino-1 : 3 : 5-triazine and 2-oxy-4 : 6-diamino-1 : 3 : 5-triazine and others referred to in Specification 468,677. Products of any degree of condensation may be used, the highly condensed products being dissolved by mixtures of water and ethyl alcohol or acids, such as hydrochloric or formic acid. Various types of dyestuffs may be fixed, even on materials which normally have no affinity for the dyestuff. The dyestuffs may be made soluble in water or an organic solvent, by salt formation, by formation of leuco-compounds, by esterifying hydroxyl groups, (cf. Specification 480,358). Intermediates in a soluble form may similarly be fixed on the fibre. The solutions may be true or colloidal. At some stage in the process the condensation product is hardened as described below, and the affinity of the hardened product for acid or basic dyestuffs, may be increased by incorporating basic or acid substances, e.g. ethylene diamine, triethanolamine, ethylamine, oxalic, citric or gallic acid, phenols, tannin or quebracho. Specified materials dyed or printed are cotton, mercerized cotton, ramie, jute, hemp, sisal, viscose and acetate artificial silks, ordinary and tussore silks, wool, paper, wood, leather, feathers, skins, furs, horn, artificial horn, ivory nut and films having a cellulose basis. In examples: (1) a paste prepared by dissolving the methylol compound of 2 : 4 : 6-triamino-1 : 3 : 5-triazine in hot water, adding tragacanth thickening, ammonia and Orange R in alcohol and, just before use, ammonium sulphocyanide, is printed on a cotton fabric; other acid dyes, e.g. Brilliant keton red B or Acid green or direct cotton dyes, e.g. Chlorantine fast orange, red or blue may be used; the prints are fast to soap solution and do not bleed; (2) a paste containing a condensation product obtained by reacting 2 : 4 : 6-triamino-1 : 3 : 5-triazine with formaldehyde on a water bath until a sample yields a thick turbidity on dilution with 10 times its volume of alcohol, Acid violet 6B, tragacanth and ammonia with addition of ammonium sulphocyanide just before use, is printed on cotton; if the condensation is carried further the printed places are stiffer and harder; (3) cotton is impregnated with a solution of the methylol compound of (1) containing ammonium sulphocyanide dried at 70 DEG C. and dyed with Kiton blue A, Orange II, Alizarin sapphire blue B or Benzyl green B; formic acid may be added to the pretreatment solution as a hardening accelerator or the material partly hardened at 70 DEG C. may be passed between heated engraved rollers to produce higher degrees of hardening locally; these parts are dyed weakly or not at all; (4) the dyestuff is incorporated with the pretreatment solution in the process of (3); (5) cotton is dyed with Direct fast orange SE, Chlorantine fast red 5BL, Cotton blue 3G, or Carbide black ER, dried and aftertreated with a solution of the methylol compound in (1) containing ammonium sulphocyanide, and dried and hardened at 70 DEG C.; (6) fabrics of cotton and of slightly chlorinated wool are printed with a paste containing tragacanth, ethyl tartrate, the methylol compound of (1) and a basic dye, e.g. Thioflavine T, Fast green JJO or Rhodamine B or an acid dye, e.g. Kiton pure blue V or Cloth fast brilliant red 2B; (7) cotton dyed with various specified direct dyes is treated as in (5), steamed or heated at 120 DEG C., for 4 minutes; (8) cotton is impregnated with a solution containing the methylol compound of (1), Indigosol O and formic acid, dried and developed with nitrous acid; (9) cotton sateen is impregnated with a solution containing the methylol compound of (1), sodium 2-naphthol-6-sulphonate and formic acid, dried, and developed in a solution of diazotized aniline; (10) cotton dyed with Rosanthrene B is aftertreated with a solution of the methylol compound of (1) and formic acid, hardened for 4 minutes at 120 DEG C., treated with nitrous acid and developed with b -naphthol; (11) cotton is printed with a paste containing the methylol compound of (1), starch-tragacanth-thickening and Ciba blue 2BD or Cibanone blue GCD, and drawn through a solution containing glycerol, potash, hydrosulphite R conc., isopropylnaphthalene - sulphonic acid and Glauber salt; (12) filter paper, foils from regenerated cellulose, wood chips, or leather are treated with a solution containing ammonia, the methylol compound of (1), an alcoholic solution of Brilliant kiton red B or Orange II, and ammonium sulphocyanide and the treated material is heated to 120 DEG C. The usual textile assistants such as filling, softening, anticreasing and water-repelling agents may be used in conjunction with the condensation products. Dye or printing preparations in liquid, paste or powder form containing the condensation products may be prepared. Specification 477,841 also is referred to.
