Description

Verfahren zur Erhöhung der Echtheitseigenschaften von Färbungen auf Acetylcellulosen mit wasserlöslichen Farbstoffen Acetylcellulose (Acetatseide) läßt sich bekanntlich mit bestimmten wasserlöslichen Farbstoffen, welche meist Alkali- oder Ammoniumsalze von Sulfo- oder Carbonsäuren sind, färben. Diese Färbungen sind aber durchweg nicht wasserecht, d. h. sie bluten schon bei einigem Verweilen in Wasser aus.Process for increasing the fastness properties of dyeings Acetyl celluloses with water-soluble dyes Acetyl cellulose (acetate silk) leaves known to be with certain water-soluble dyes, which are mostly alkali or are ammonium salts of sulfo or carboxylic acids, color. These colorations are but not water-proof, d. H. they bleed even if they linger a while Water out.

Es wunde nun überraschenderweise gefunden, daß man diesen Übelstand beheben und wasserechte Färbungen erzielen kann, wenn man die mit wasserlöslichen Farbstoffen gefärbte Acetylcellulose mit wäßri,gen Lösungen fällend wirkender organischer Salze, welche selbst in organischen Lösungsmitteln, wie Essigester, löslich sind, nachbehandelt. Insbesondere eignen sich hierzu die Salze der Arylbiguanide.Surprisingly, it has now been found that this deficiency can be found fix and achieve water-fast colorations if you use those with water-soluble Acetyl cellulose colored with dyes with aqueous solutions of organic precipitating effects Salts that are soluble in organic solvents such as ethyl acetate, post-treated. The salts of the aryl biguanides are particularly suitable for this purpose.

Beispiel i: 2o g Acetylcellulose (Acetatseide), welche mit dem Farbstoff q. - nitro - i- aminobenzolazo r i-methyl-a-oxybenzol-3-carbonsaures Natrium 2,5prozentig gefärbt sind, werden bei Zimmertemperatur in ein Bad getaucht, welches aus einer Lösung von 2,5 g salzsaurem Phenylbiguanid und q. g Natriumchlorid in 8oo ccm Wasser besteht. Das Bad. wird 1/2 Stunde lang auf 6o bis 70° erwärmt, die Seide öfter umgezogen, darauf gespült und getrocknet.Example i: 20 g of acetyl cellulose (acetate silk), which is mixed with the dye q. - nitro - i- aminobenzolazo r i-methyl-a-oxybenzene-3-carboxylic acid sodium 2.5 percent colored are immersed in a bath at room temperature, which consists of a Solution of 2.5 g of hydrochloric acid phenyl biguanide and q. g of sodium chloride in 8oo cc of water consists. The bathroom. is heated for 1/2 hour to 6o to 70 °, the silk is changed more often, then rinsed and dried.

ao g Acetylcellulose (Acetatseide), welche mit dem Farbstöff 3, ,q. - Dichlor - i- aminobenzol-6-sulfosäureazo -> - a-äthylaminonaphthalin z, 5prozentig gefärbt sind, werden wie in Beispiel i mit einer Lösung von salzsaurem z-Naphthylaminbiguanid und q. g Natriumchlorid :(oder 3 g Natriumchlorid und i g Natriumacetat) in 8oo g Wasser nachbehandelt. Die Färbung ist jetzt wasch- und wasserecht.ao g acetyl cellulose (acetate silk), which is mixed with the dye 3,, q. - Dichloro - i-aminobenzene-6-sulfonic acid azo -> - a-ethylaminonaphthalene z, 5 percent are colored, as in Example i with a solution of hydrochloric acid z-naphthylamine biguanide and q. g sodium chloride: (or 3 g sodium chloride and ig sodium acetate) in 8oo g water. The dye is now washable and waterfast.

Das 2-Naphthylaminbiguanid, C@2N5H13, entsteht aus salzsaurem 2-Naphthylamin und Dicyandiamid (Cyanguanidin) durch Kochen der wäßrigen Lösung. Es bildet weiße, in Wasser schwer lösliche Blättchen vom Schmp. 17q.°. N-Gehalt: Nach der Theorie 30,8 Prozent, gefunden 3o,68 Prozent. Das salzsaure Salz bildet weiße Nadeln, die in heißem Wasser leicht löslich sind. N-Gehalt: Nach der Theorie 26,6 Prozent, gefunden 26,1 Prozent.The 2-naphthylamine biguanide, C @ 2N5H13, is formed from hydrochloric acid 2-naphthylamine and dicyandiamide (cyanguanidine) by boiling the aqueous solution. It forms white, sparingly water-soluble leaflets with a melting point of 17q. °. N-content: According to the theory 30.8 percent, found 3o, 68 percent. The hydrochloric acid salt forms white needles that are easily soluble in hot water. N content: According to the theory, 26.6 percent, found 26.1 percent.

Statt der erwähnten Arylbiguanide lassen sich auch die salzsauren Lösungen von Guanylharnstoff, z-Naphthylamin, p-Aminodiphenylamin und andere verwenden.Instead of the aryl biguanides mentioned, the hydrochloric acid can also be used Use solutions of guanylurea, z-naphthylamine, p-aminodiphenylamine, and others.
