Description

Verfahren zum Färben von Halbwolle Die Erfindung bezieht sich auf ein Verfahren zum Färben von Halbwolle, insbesondere mit alkaliechten Farbstoffen.Method of dyeing semi-wool The invention relates to a process for dyeing half wool, especially with alkali-fast dyes.

Beim Färben von Halbwolle entstehen, z. B. infolge trüben Aufziehens der Farbe oder Verklebungen bzw. Verfilzungen des Halbwollematerials, Schwierigkeiten.When dyeing half wool arise, z. B. as a result of cloudy pulling up the color or sticking or matting of the semi-wool material, difficulties.

Unter Umständen ergeben sich Färbungen, die verhältnismäßig wenig Echtheit gegenüberWaschen zeigen, wobei die Färbungen verhältnismäßig tief ausfallen können.Under certain circumstances, there are stains that are relatively little Show fastness to washing, the colorations turning out to be comparatively deep can.

Es ist vorgeschlagen worden, Sulfitcelluloseablauge, d. h. lignosulfonsaures Natrium, Färbebädern zum Färben von Halbwolle zuzusetzen. Ein Erfolg wird durch einen solchen Zusatz nicht erreicht. Im Gegenteil wird unter Umständen eine trübere Färbung erhalten und ein Verfilzen bzw. Verkleben des gefärbten Halbwollematerials nicht verhindert.It has been proposed to use sulphite cellulose waste liquor, i.e. H. lignosulfonic acid Sodium, add dye baths for dyeing half wool. A success will be through such an addition was not achieved. On the contrary, it may become cloudy Obtained dyeing and felting or gluing of the dyed half-wool material not prevented.

Nach der Erfindung wird nun vorgeschlagen, diese Übelstände aus der Welt zu schaffen durch Durchführen des Färbens von Halbwolle unter Zusatz von löslichen, unsulfurierten, verhältnismäßig hochmolekularen Ligninumwandlungsprodukten, insbesondere solchen, die -durch Behandlung von Holzhydrolyselignin z. B. mit alkalischen Flüssigkeiten, wie verdünnter Natronlauge, gewonnen @verden können. Auch können durch ein solches Vorgehen Färbungen erzielt werden, die gegenüber Wäschen verhältnismäßig echt und tiefer sind als die ohne Zusatz erhaltenen.According to the invention, it is now proposed that these shortcomings from the To create the world by performing the dyeing of half wool with the addition of soluble, unsulfurized, relatively high molecular weight lignin conversion products, in particular those -by treatment of wood hydrolysis z. B. with alkaline liquids, like diluted caustic soda, obtained @verden. Also can through such a proceed Dyes are achieved that are relatively real and deeper than washes are than those obtained without addition.

Statt eines solchen Alkalilignins können auch die Behandlungsprodukte von Ligninkörpern mit anderen Stoffen, wie z. B,. Phenol, Alkohol, Dioxan oder Glykol mit oder ohne Säure, wie z. B@. Salzsäure, oder sauer wirkende Stoffe als Katalysatoren verwendet werden. Als Ausgangsstoffe dienen verhältnismäßig wenig oder gar nicht abgebaute Ligninstofe, da die Wirkung um so besser ist, je höhermolekular diese Ligninstoffe und-die Ligninbehandlungsprodukte sind. Insbesondere sind geeignet die Ligninstoffe, die bei Verfahren anfallen, bei denen es auf das Herauslösen der Gellulose aus dem Ligninskelett ankommt. So eignen sich vor allem die Restprodukte der Holzhydrolyse; nicht geeignet für die Erfindung sind Reaktionsprodukte von stark abgebautem Lignin mit schwefliger Säure, da diese Umwandlungsprodukte S 0"3H-Gruppen enthalten. Solche Reaktionsprodukte sind nicht als Ligninumwandlungsprodukte gemäß der Erfindung aufzufassen.Instead of such an alkali lignin, the treatment products of lignin bodies with other substances, such as B ,. Phenol, alcohol, dioxane or glycol with or without acid, such as B @. Hydrochloric acid or acidic substances as catalysts be used. Relatively little or not at all are used as starting materials degraded lignin substances, since the higher molecular weight, the better the effect Lignin substances and -which are lignin treatment products. In particular, are suitable the lignin substances that arise in procedures that involve the leaching of the Cellulose arrives from the lignin skeleton. The residual products are particularly suitable wood hydrolysis; reaction products of stark are not suitable for the invention degraded lignin with sulphurous acid, since these conversion products S 0 "3H groups contain. Such reaction products are not in accordance with as lignin conversion products of the invention to be understood.

Die Gewinnung der Ligninumwandlungsprodukte nach der Erfindung geschieht auf an sich bekannte Weise. Bei Produkten, die aus Sulfitcelluloseablauge gewonnen wurden, ist das Lösen in Alkali, Phenol usw. versucht worden. Im Gegensatz zu diesen Stoffen löst sich das Holzhydrolyselignin in Alkalilaüge nicht vollständig, jedoch kann die Lösung ohne weiteres von dem Rückstand abgetrennt werden.The lignin conversion products are obtained according to the invention in a known way. For products made from sulphite cellulose waste liquor dissolving in alkali, phenol, etc. has been attempted. In contrast to these In substances, the wood hydrolysis lignin does not completely dissolve in alkali, but it does the solution can be readily separated from the residue.

Für die Erfindung kommt vor allem das Färben mit alkaliechten Farbstoffen in Betracht, insbesondere dann, wenn Alkaliumwandlungsprodukte des Lignins angewendet werden. Diese Alkaliumwandlungsprodukte können in der anfallenden Behamdlungslösung, gegebenenfalls nach Eindampfen, verwendet werden, oder es können auch die Ligninumwandlungsprodukbe aus den Lösungen auf an sich bekannte Weise, z. B,. Aussalzen und/oder Einengen, zur Trockene gebracht werden.Dyeing with alkali-resistant dyes is particularly important for the invention into consideration, especially if alkali conversion products of lignin are used will. These alkali conversion products can be found in the resulting treatment solution, optionally after evaporation, or the lignin conversion products can also be used from the solutions in a manner known per se, e.g. B ,. Salting out and / or concentration, brought to dryness.

Die optimale Menge des Ligninumwandlungskörpers kann durch einfache Vorversuche ermittelt werden. Es genügen verhältnismäßig sehr geringe Mengen, z. B. von 5 g und weniger je Liter. Eine wesentliche Verteuerung des Verfahrens tritt nicht ein. Der Preis der_Ligninumwandlungskörper spielt im Verhältnis zu dem hervorgebrachten Effekt keine Rolle.The optimal amount of the lignin conversion body can be determined by simple Preliminary tests are determined. Relatively very small amounts are sufficient, e.g. B. of 5 g and less per liter. A substantial increase in the cost of the procedure occurs not a. The price of the lignin conversion body plays in relation to what is produced Effect does not matter.

Beispiel 5o g Halbwolle (5o% Zellwolle, 5o% tierische Faser) werden in der üblichen Weise mit einem für die Unifärbung geeigneten Farbstoff, z. B. Halbwollgrün B, einem Diäthylsafranin-azodimethylanilin, unter gleichzeitigem Zusatz von 5 g je Liter eines Ligninumwandlungskörpers gefärbt, der auf folgende Weise erhalten wurde: iooo Teile Holzhydrolyselignin werden während z Stunden in dem Flottenverhältnis i : io mit einer 5%igen Natronlauge gekocht. Dann wird von dem ungelöst Gebliebenen abgetrennt und die .erhaltene braune Lösung auf einen Trockengehalt von etwa 5o bis 6o0% an organischer Substanz eingedampft.Example 50 g half wool (50% viscose wool, 50% animal fiber) in the usual way with a dye suitable for solid color, e.g. B. Half-wool green B, a diethylsafranine azodimethylaniline, with the simultaneous addition of 5 g colored per liter of a lignin conversion body obtained in the following manner was: 10000 parts of wood hydrolysis lignin are in the liquor ratio for z hours i: io cooked with a 5% sodium hydroxide solution. Then it becomes of what has remained unsolved separated and the brown solution obtained to a dry content of about 5o evaporated up to 60% of organic matter.

Es ergibt sich eine weit tiefere Anfärbung mit wesentlich besserer Echtheit gegenüber dem Waschprozeß als bei Durchführung einer Normalfärbung unter genau gleichen- Bedingungen, jedoch ohne Alkaliligninzusatz.The result is a much deeper staining with a much better one Fastness to the washing process than when carrying out normal dyeing under exactly the same conditions, but without the addition of alkali lignin.
