Description

Verfahren zum Färben von Celluloseestern und -äthern I#ie meisten Azofarbstoffe, welche eine Sulfogruppe enthalten, zeigen keine Verwandtschaft zu Celluloseestern und -äthern.Process for dyeing cellulose esters and ethers - most of them Azo dyes which contain a sulfo group show no relationship Cellulose esters and ethers.

Wie gefunden wurde, haben die durch Kuppeln von unsulfierten aromatischen Diazoverbindungen. mit 2 - 4-Diaminophenylmethanstilfosäure entstehenden Farbstoffe bei, guter Wasserlöslichkeit starke Verwandtschaft zu Celltiloseestern und -äthern. Sie ziehen z. B. auf Acetatseide mit gelber bis roter Tönung auf. Beispiel r 2,5 Teile des Farbstoffes Aminobenzolazo ) 2 - 4 - diarninophenylmethansulfosäure werden in i ooo Teilen Wasser heiß gelöst. Man färbt Acetatseide mit oder ohne Zusatz von Sulfaten 81, Stunde bei 70'. Die Färbung ist strohgelb. Beispiel 2 2"5 Teile des Farbstoffes 4-NitrO-1-aminobenzolazo > 2 -4-diaminophenylmethansulfosäure werden in i ooo Teilen Wasser gelöst. Man verfährt wie in Beispiel i und erhält ein Corinth.The coupling of unsulfated aromatic diazo compounds has been found to have. for 2 - 4 Diaminophenylmethanstilfosäure resulting dyes upon, good water solubility strong relationship to Celltiloseestern and -äthern. You pull z. B. on acetate silk with a yellow to red tint . Example r 2.5 parts of the dye Aminobenzolazo) 2 - 4 - diarninophenylmethansulfosäure are dissolved in i ooo parts of water hot. Acetate silk is dyed with or without the addition of sulfates 81, hour at 70 '. The color is straw yellow. Example 2 2 "5 parts of the dye 4-NitrO-1-aminobenzolazo > 2 -4-diaminophenylmethanesulfonic acid are dissolved in 1,000 parts of water. The procedure is as in Example 1 and a Corinth is obtained.

Beispiel 3 Man ersetzt den in Beispiel i genannten Farbstoff durch die gleiche Menge des Farbstoffes i-Aminonaphthaaazo -> 2 - 4-diaminophenylmethansulfosäure. Man erhält ein Orange.EXAMPLE 3 replaces the example in i-mentioned dye by the same amount of the dye I Aminonaphthaaazo -> 2-4-diaminophenylmethansulfosäure. You get an orange.
