Description
Verfahren zur Herstellung eines wasserunlöslichen Azofarbstoffs auf pflanzlichen Fasern Es wurde gefunden, daß man lebhafte rüte Färbungen auf pflan#zli#lilen Fasern erhält, wenn man- 2- (2, 3'-Oxynaphi.thoylamino) -naphthalin mit diazotiertem i-Amino-2-m#eihoxybeilzol-5-stilfonsäure-n-bu,tylamid nach Eisfarbdnart vereinigt.Process for the preparation of a water-insoluble azo dye Vegetable Fibers It has been found that vivid, dark colorations can be found on vegetable fibers Fibers are obtained when 2- (2, 3'-Oxynaphi.thoylamino) naphthalene is diazotized i-Amino-2-m # eihoxybeilzol-5-stilfonsäure-n-bu, tylamide combined according to ice color.
Man erhält im Gegensatz zu den Angaben in der Patetitschlift 604 135 eine gut naßechte sowie sehr gut lichtechte lebhafte rote Färbung, die der bekannten, durch Kuippeln vo-ndiazotiertem i-Amin0-2-Ä.thoxybenz,ul-5-s-ulfo,n,säuredim,eth.ylanud mit der gleich-en Azokomponente erhältlichen Färbung in der Lebhaftigkeit des Farbtons und in der Lichtechtheit überlegen ist. Beispiel 50 g abgekochtes Baumwollgarn werden in dem nachstehenden Grundierungsbad a 1/2 Stunde behandelt, durch Abwinden, Ab- quetschen oder Schleudern gut entm,ässert und in nachstehendem Entwicklungsbad b 1/2 Stunde entwickelt.In contrast to the information in Patetitschlift 604 135, the result is a good wetfast and very good lightfast vivid red coloration, similar to the known i-amin0-2-Ä.thoxybenz, ul-5-s-ulfo, n, säuredim, eth.ylanud with the same azo component available coloring is superior in the vividness of the hue and in the lightfastness. Example 50 g of boiled cotton are treated in the following Grundierungsbad a 1/2 hour, by unwinding, squeezing off or spinning entm well ässert and indicated in the following developing bath b 1/2 hour developed.
a. Grundierungsbad 2 9 2-(2', 3'-Oxynaphthoylamino)-iiaphthalin, 4 ccm Soprozentiges Türkischrotöl, 6 - Natronlauge von 34' B6, 2 - 3oprozentige Formaldehydlösung, 5oo. - siedendes Wasser, dann -mit Wasser aufgefüllt auf 1 1. b. Entwicklungsbad 2,6 g i-Amino-2-methoxybenzol-5-sulfonsäuren-butylarnid vom F. i:o3' C werden mit 2#,8 ccm Salzsäure von 22' B6 und o,7 g in etwas Wasser gelöstem Natriumnitrit unter Eiszusatz diazotiert. Nach Beendigung der Diazotierung stumpft man die Lösung mit etwa - 2,5 g Natriumacetat ab, setzt eine Lösung von 25,0 g Natriumchlorid in Wasser zu und füllt mit Wasser auf 11 auf. Dann wird Idas Färbegut gespült, kocIiend geseift, nochmals gespült und getrocknet.a. Primer bath 2 9 2- (2 ', 3'-Oxynaphthoylamino) -iiaphthalin, 4 ccm 5% Turkish red oil, 6 - caustic soda from 34' B6, 2 - 3% formaldehyde solution, 500. - boiling water, then -filled with water to 1 1. b. Development bath 2.6 g of i-amino-2-methoxybenzene-5-sulfonic acid butyl amide from F. i: o3 ' C are mixed with 2 #, 8 ccm of hydrochloric acid from 22' B6 and 0.7 g of sodium nitrite dissolved in a little water with the addition of ice diazotized. After completion of the diazotisation blunts the solution of about - 2.5 g of sodium acetate from a solution is of 25.0 g of sodium chloride in water and made up to 1 1 with water. Then Idas dyed material is rinsed, soaped with coconut oil, rinsed again and dried.
Man erhält so einelebhafte roteFärbungvon gu-#ten Naßechtheiten und sehr guter Lichtechtheit.This gives a vivid red coloration with good wet fastness properties and very good lightfastness.
