Description

Verfahren zum Färben von Kunstseide aus Celluloseestern oder -äthern bzw. deren Umwandlungsprodukten Die Aminoanthrachinone und ihre Derivate besitzen die Eigenschaft, in feiner Verteilung, in sogenannter Pastenforrn, Acetatseide kräftig anzufärben. Die so erzielten Ausfärbungen sind jedoch nicht echt; es ist z. B. die Reibechtheit ungenügend.Process for dyeing rayon from cellulose esters or ethers or their conversion products The aminoanthraquinones and their derivatives have the property, in fine distribution, in so-called paste form, acetate silk strong to color. However, the colorations achieved in this way are not genuine; it is Z. B. the Inadequate rubbing fastness.

Es wurde nun gefunden, daß man unter Verwendung gewisser Zusätze zum Färbebad diese Übelstände völlig vermeiden kann. Als besonders geeignet haben sich die Einwirkungsprodukte von Schwefel auf Phenole, wie sie z. B. in -der Patentschrift 348 530 und ihren Zusätzen beschrieben sind, erwiesen. Die so hergestellten Färbungen entsprechen allen Anforderungen. Man. kann je nach Wahl der Aminoanthrachinone gelbe, orange, violette, blaue und durch Gemische auch grüne Färbungen erzielen.It has now been found that these inconveniences can be completely avoided by using certain additives to the dye bath. The products of action of sulfur on phenols, such as those used, for. B. in -the patent 348 530 and its additions are proven. The dyeings produced in this way meet all requirements. Man. can, depending on the choice of aminoanthraquinones, achieve yellow, orange, violet, blue and, through mixtures, also green colorations.

Man kann auch die Anthrachinonderivate mit dem Zusatz mischen und diese direkt zum Färben verwendbaren Mischungen in den Handel bringen.You can also mix the anthraquinone derivatives with the additive and bring these mixtures which can be used directly for dyeing on the market.

Die bei diesem neuen Färbeverfahren verwendeten Zusätze haben gegenüber denjenigen von Seifen, Türkischrotölen den Vorzug, wasch- und wasserechtere Färbungen zu ergeben.The additives used in this new dyeing process have opposite those of soaps, Turkish red oils prefer, dyeings that are more resistant to washing and water to surrender.

Beispiel Durch Lösen von a-Aminoanthrachinon in konz. Schwefelsäure und Eingießen der Lösung in Wasser usw. stellt man eine neutrale Paste her. Man löst in der Färbeflotte etwa 5 % des neutralen Einwirkungsproduktes von Schwefel auf Phenol (siehe Patent 348 530) bezogen auf das Färbegut und färbt im Flottenverhältnis i :2o in einer Stärke von i bis s % festen Farbstoffs bei 6o bis 7o° etwa drei Viertel bis eine Stunde aus. Der Farbstoff zieht auf Acetatseide in leuchtenden orangen Tönen von sehr guter Reib-, Wasch-, Wasser-und Lichtechtheit auf.Example By dissolving α-aminoanthraquinone in conc. Sulfuric acid and pouring the solution into water, etc. to make a neutral paste. Dissolve about 5% of the neutral action product of sulfur on phenol (see patent 348 530) based on the material to be dyed in the dye liquor and dye in a liquor ratio of i: 2o with a strength of 1 to 5% solid dye at 6o to 7o ° about three quarters up to an hour. The dye is absorbed onto acetate silk in bright orange tones of very good rub, wash, water and lightfastness.

ß-Aminoanthrachinon.gibt in gleicher Weise gefärbt ein schönes Gelb von sehr guten Echtheitseigenschaften.ß-Aminoanthraquinone gives a beautiful yellow colored in the same way of very good fastness properties.

i # 4-Daminoanthrachinon färbt die Seide leuchtend violett mit sehr guter Reib-, Wasch-und Wasserechtheit.i # 4-Daminoanthraquinone colors the silk bright purple with very good rubbing, washing and water fastness.

i - 4 - 5 ' 8-Tetraminoanthrachinon gibt auf der Seide ein schönes klares, sehr echtes Blau. a-Methylaminoanthrachinon gibt ein schönes Rot.i - 4 - 5 '8-Tetraminoanthraquinone gives a beautiful appearance to the silk clear, very real blue. a-methylaminoanthraquinone gives a nice red color.

Auch Mischungen obiger Farbstoffe lassen sich verwenden. So gibt ein Gemisch. von ß-Aminoanthrachinon mit i # 4 # 5 # 8-Tetraminoanthrachnon ein Olive.Mixtures of the above dyes can also be used. So gives a Mixture. of ß-aminoanthraquinone with i # 4 # 5 # 8-tetraminoanthraquinone an olive.
