  • Another advantage of the method according to the invention relates to the reduction in the setting which is achieved by the presence of a compound of the formula (1) or (1 ') in the dyebath.
  • a setting is an undesired fixation of the wool fibers that occurs during the dyeing process, which is caused by rearrangement of the disulfide bridges contained in the wool.
  • Such undesirable fixations can, for example, result in a deformation (flattening) of the wool yarns on bobbins, one Compacting the wool fibers as well as expressing a loss in the volume of the wool.
  • the antisetting effect of a wool protection agent can e.g. based on A.M. Wemys and M.A. White, Proc. Ind. Japan-Australia, Joint Symp. On objective measurement, Kyoto (1985), page 165, can be determined by punching rondelles out of wool test fabric, folding them in the middle and sewing them together at the edge. The test specimens are then dyed in the pressed state in the presence of the wool protection agent, the fabric samples are then opened and a thread is pulled out in each case. After a recovery period in warm water, the angle of the threads is measured. The more the previously compressed yarn has opened and the closer the measured angle approaches 180 °, the better the anti-setting effect of the wool protection agent. A measured angle of approximately 120 to 180 ° and in particular 140 to 180 ° indicates a good anti-setting effect.
  • Parts mean parts by weight, percentages by weight.
  • Example 2 18.4 parts of glycerol, 55.9 parts of maleic anhydride and 0.3 part of tributylamine are placed in a sulfonation flask. The mixture is carefully warmed to about 100 ° C. and then left to stir at this temperature for about 5 hours. The titration of the carboxyl groups indicates the end of the reaction. It is cooled to about 50 ° C., diluted with 40 parts of water and neutralized to pH 6 by adding about 303 parts of 2N sodium hydroxide solution. After filtering off undissolved particles, one obtains the compound of formula as a 20% solution.
  • Example 5 20.1 parts of 1,1,1-trihydroxymethylpropane, 41.9 parts of maleic anhydride and 0.3 part of tributylamine are placed in a sulfonation flask. The mixture is carefully warmed to about 100 ° C. and then left to stir at this temperature for about 5 hours.

Description

Die vorliegende Erfindung betrifft ein neues Verfahren zum Hochtemperatur-Färben von Wolle oder wollhaltigen Fasermaterialien.The present invention relates to a new process for high-temperature dyeing wool or wool-containing fiber materials.

Es ist bekannt, Wolle oder wollhaltige Fasermaterialien in Gegenwart von Hilfsmitteln zu färben, um so Faserschädigungen entgegenzuwirken, welche insbesondere beim Hochtemperatur-Färben auftreten. Viele der bekannten Hilfsmittel enthalten Formaldehyd oder setzen beim Erhitzen Formaldehyd frei, was toxikologisch nicht unbedenklich ist.It is known to dye wool or wool-containing fiber materials in the presence of auxiliaries in order to counteract fiber damage which occurs in particular during high-temperature dyeing. Many of the known auxiliaries contain formaldehyde or release formaldehyde when heated, which is not toxicologically harmless.

Es wurde nun überraschend ein verbessertes Verfahren zum Hochtemperatur-Färben von wollhaltigen Fasermaterialien gefunden, welches auf der Verwendung einer neuen Klasse von Wollschutzmitteln basiert.Surprisingly, an improved process for high-temperature dyeing of wool-containing fiber materials has now been found, which is based on the use of a new class of wool protection agents.

Gegenstand der vorliegenden Erfindung ist somit ein Verfahren zum Färben von wollhaltigen Fasermaterialien mit anionischen Farbstoffen, welches dadurch gekennzeichnet ist, dass man diese Materialien in Gegenwart eines Wollschutzmittels enthaltend mindestens eine Verbindung der Formel

Bevorzugt ist die Verwendung von Alkylenglykolen als Verdünnungsmittel für die erfindungsgemässen Wollschutzmitteln.The products of the formula (1) and (1 ') obtained in the reaction can either be used directly or, e.g. after dilution with one or more suitable solvents, they can be used as wool protection agents. Solvents suitable for dilution are e.g. Water or alkylene glycols or alkylene glycol ethers such as e.g. Polyethylene glycol 200, propylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol, tripropylene glycol or their monomethyl, monoethyl, monobutyl, dimethyl, diethyl or dibutyl ether, e.g. Diethylene glycol monomethyl ether or monoethyl ether, diethylene glycol dimethyl ether or diethyl ether, ethylene glycol monobutyl ether or dibutyl ether or diethylene glycol monobutyl ether or dibutyl ether. Preferred is the use of alkylene glycols as diluents for the wool protection agents according to the invention.

Die Verbindungen der Formel (5), (6a), (6b) und (6c) sind an sich bekannt oder können nach an sich bekannten Methoden erhalten werden.The compounds of the formula (5), (6a), (6b) and (6c) are known per se or can be obtained by methods known per se.

Die erfindungsgemäss eingesetzten Wollschutzmittel können eine oder mehrere der Verbindungen der Formel (1) enthalten. Eine Ausführungsform der vorliegenden Erfindung ist dadurch gekennzeichnet, dass man ein Wollschutzmittel enthaltend je mindestens eine Verbindung der Formeln (1) und (1') verwendet. Es ist auch möglich, Wollschutzmittel zu verwenden, die eine Verbindung der Formel (1) oder (1') und eine weitere Verbindung mit wollschützender Wirkung, z.B. 3-Chlor-1,2-propandiol, enthalten.The wool protection agents used according to the invention can contain one or more of the compounds of the formula (1). One embodiment of the present invention is characterized in that a wool protection agent containing at least one compound of the formulas (1) and (1 ') is used. It is also possible to use wool protection agents which contain a compound of formula (1) or (1 ') and another compound with a wool protection effect, e.g. 3-chloro-1,2-propanediol.

Man geht z.B. so vor, dass man das wollhaltige Fasermaterial zuerst mit dem Wollschutzmittel in einem wässrigen Bad vorbehandelt und anschliessend durch Zugabe des Farbstoffs zu diesem Bad färbt. Man kann auch so vorgehen, dass man das Färbegut gleichzeitig mit dem Wollschutzmittel und dem Farbstoff in einem wässrigen Bad behandelt.One goes e.g. so that the wool-containing fiber material is first pretreated with the wool protection agent in an aqueous bath and then dyed by adding the dye to this bath. It is also possible to treat the material to be dyed simultaneously with the wool preservative and the dye in an aqueous bath.

Es hat sich als praktikabel erwiesen, das Wollschutzmittel in einer Menge von z.B. 0,1 bis 20 Gew.-%, bevorzugt 0,1 bis 10 Gew.-%, besonders bevorzugt 1 bis 10 Gew.-% und insbesondere bevorzugt 1 bis 6 Gew.-%, jeweils bezogen auf das Gewicht des Färbeguts, einzusetzen.It has proven to be practical to use the wool protection agent in an amount of, for example, 0.1 to 20 wt .-%, preferably 0.1 to 10 wt .-%, particularly preferably 1 to 10 wt .-% and particularly preferably 1 to 6 wt .-%, each based on the weight of the material to be used.

Bei dem wollhaltigen Fasermaterial kann es sich um Wolle allein oder um Mischungen aus z.B. Wolle/Polyamid oder Wolle/Polyester handeln. Dabei werden Gemische aus Wolle und synthetischem Polyamid vorzugsweise mit anionischen Farbstoffen und Gemische aus Wolle und Polyesterfasern vorzugsweise mit Dispersions- und anionischen Farbstoffen gefärbt. Geeignete anionische Farbstoffe und Dispersionsfarbstoffe sind dem Fachmann bekannt.The wool-containing fiber material can be wool alone or a mixture of e.g. Trade wool / polyamide or wool / polyester. Mixtures of wool and synthetic polyamide are preferably dyed with anionic dyes and mixtures of wool and polyester fibers are preferably dyed with disperse and anionic dyes. Suitable anionic dyes and disperse dyes are known to the person skilled in the art.

Das Fasermaterial kann in den verschiedensten Verarbeitungsstadien vorliegen, z.B. in Form von Garnen, Flocken, Kammzug, Maschenware, wie Strickware oder Gewirke, als Faservliesstoff oder vorzugsweise als Gewebe.The fiber material can be in various stages of processing, e.g. in the form of yarns, flakes, sliver, knitwear such as knitwear or knitted fabrics, as a nonwoven fabric or preferably as a woven fabric.

Bei den Mischfasermaterialien handelt es sich vorzugsweise um Fasermischungen aus Wolle und Polyester, die in der Regel in einem Teilverhältnis von 20 bis 50 Gewichtsteilen Wolle zu 80-50 Gewichtsteilen Polyester vorliegen. Die für das Verfahren bevorzugten Fasermischungen enthalten 45 Teile Wolle und 55 Teile Polyesterfasern.The mixed fiber materials are preferably fiber blends of wool and polyester, which are generally present in a proportion of 20 to 50 parts by weight of wool to 80-50 parts by weight of polyester. The fiber mixtures preferred for the process contain 45 parts of wool and 55 parts of polyester fibers.

Das Flottenverhältnis kann beim erfindungsgemässen Verfahren innerhalb eines weiten Bereiches gewählt werden; es beträgt z.B. 1:1 bis 1:100 und vorzugsweise 1:10 bis 1:50.The liquor ratio can be selected within a wide range in the process according to the invention; it is e.g. 1: 1 to 1: 100 and preferably 1:10 to 1:50.

Das Färbebad kann neben dem Farbstoff, Wasser und dem Wollhilfsmittel weitere übliche Zusätze enthalten. Zu erwähnen sind z.B. Mineralsäuren, organische Säuren und/oder deren Salze, die der Einstellung des pH-Werts des Färbebads dienen, weiterhin Elektrolyte, Egalisier-, Netz- und Entschäumungsmittel sowie, falls es sich um das Färben von Wolle/Polyester-Gemischen handelt, Carrier und/oder Dispergiermittel.In addition to the dye, water and the wool auxiliary, the dyebath can contain other customary additives. Worth mentioning are e.g. Mineral acids, organic acids and / or their salts, which serve to adjust the pH value of the dye bath, further electrolytes, leveling agents, wetting agents and defoamers and, if dyeing wool / polyester mixtures, carriers and / or dispersant.

Das Färbebad weist einen pH-Wert von z.B. 4 bis 6,5 und vorzugsweise von 5,2 bis 5,8 auf. Das erfindungsgemässe Verfahren wird im allgemeinen bei einer Temperatur von z.B. 60 bis 130°C durchgeführt.The dye bath has a pH of e.g. 4 to 6.5 and preferably from 5.2 to 5.8. The process according to the invention is generally carried out at a temperature of e.g. 60 to 130 ° C carried out.

Wenn das zu färbende Material Wolle allein ist, erfolgt die Färbung zweckmässig nach dem Ausziehverfahren, z.B. bei einer Temperatur im Bereich 60 bis 106°C, vorzugsweise 95 bis 98°C. Die Färbedauer kann in Abhängigkeit von den Erfordernissen variieren, beträgt jedoch vorzugsweise 60-120 Minuten.If the material to be dyed is wool alone, the dyeing is expediently carried out by the exhaust process, for example at a temperature in the range from 60 to 106 ° C., preferably from 95 to 98 ° C. The dyeing time can vary depending on the requirements, however, it is preferably 60-120 minutes.

Die Färbungen der Polyester/Wolle-Mischfasermaterialien erfolgen mit Vorteil einbadig aus wässriger Flotte nach dem Ausziehverfahren. Man färbt vorzugsweise nach dem sogenannten Hochtemperaturverfahren in geschlossenen, druckbeständigen Apparaturen bei Temperaturen von über 100°C, zweckmässig zwischen 110 und 125°C und vorzugsweise bei 118-120°C und gegebenenfalls unter Druck.The dyeing of the polyester / wool mixed fiber materials is advantageously carried out in a single bath from an aqueous liquor using the exhaust process. Dyeing is preferably carried out by the so-called high-temperature process in closed, pressure-resistant apparatus at temperatures above 100 ° C., expediently between 110 and 125 ° C. and preferably at 118-120 ° C. and optionally under pressure.

Die Mischfasermaterialien können auch nach dem üblichen Carrier-Färbeverfahren bei Temperaturen unter 106°C, z.B. im Temperaturbereich von 75 bis 98°C in Gegenwart eines oder mehrerer Carrier gefärbt werden.The mixed fiber materials can also be processed by the usual carrier dyeing process at temperatures below 106 ° C, e.g. in the temperature range from 75 to 98 ° C in the presence of one or more carriers.

Das Färben der Polyester/Wolle-Mischfasermaterialien kann so durchgeführt werden, dass man das Färbegut zuerst mit dem Wollschutzmittel und gegebenenfalls dem Carrier behandelt und anschliessend färbt. Man kann auch so vorgehen, dass man das Färbegut gleichzeitig mit dem Wollschutzmittel, den Farbstoffen und gegebenenfalls Hilfsmitteln behandelt. Vorzugsweise geht man mit dem Textilmischfasermaterial in eine Flotte ein, die das Wollschutzmittel und gegebenenfalls weitere übliche Hilfsmittel enthält und eine Temperatur von 40-50°C aufweist, und behandelt das Material 5 bis 15 Minuten bei dieser Temperatur. Danach erhöht man die Temperatur auf ca. 60 bis 70°C, gibt den Farbstoff zu, erhitzt langsam auf die Färbetemperatur und färbt dann ca. 20 bis 60, vorzugsweise 30 bis 45 Minuten, bei dieser Temperatur. Am Schluss wird die Flotte auf etwa 60°C abgekühlt und das gefärbte Material wie üblich aufgearbeitet.The dyeing of the polyester / wool mixed fiber materials can be carried out by first treating the material to be dyed with the wool protection agent and, if appropriate, the carrier, and then dyeing. One can also proceed in such a way that the material to be dyed is treated simultaneously with the wool preservative, the dyes and, if appropriate, auxiliaries. The textile mixed fiber material is preferably added to a liquor which contains the wool protection agent and, if appropriate, other customary auxiliaries and has a temperature of 40-50 ° C., and the material is treated at this temperature for 5 to 15 minutes. The temperature is then increased to about 60 to 70 ° C., the dye is added, the mixture is slowly heated to the dyeing temperature and then dyeing is carried out at this temperature for about 20 to 60, preferably 30 to 45 minutes. Finally, the liquor is cooled to about 60 ° C and the colored material is worked up as usual.

Mittels des erfindungsgemässen Verfahrens ist es möglich, Wolle oder insbesondere Wolle/Polyester-Fasergemische bei hoher Temperatur unter einwandfreiem Schutz des Wollanteils, d.h. unter Erhaltung der wichtigen, fasertechnologischen Eigenschaften der Wolle, wie Reissfestigkeit, Berstbeständigkeit und Dehnung, zu färben. Hervorzuheben ist weiterhin, dass der Polyesteranteil bei Mischgeweben keine Angilbung zeigt.By means of the method according to the invention it is possible to wool or in particular wool / polyester fiber mixtures at high temperature with perfect protection of the wool content, i.e. dyeing while preserving the important fiber-technological properties of the wool, such as tear resistance, bursting resistance and elongation. It should also be emphasized that the proportion of polyester in mixed fabrics shows no yellowing.

Ein weiterer Vorteil des erfindungsgemässen Verfahrens betrifft die Verringerung des Settings, die durch die Anwesenheit einer Verbindung der Formel (1) bzw. (1') im Färbebad erreicht wird. Als Setting bezeichnet man eine unerwünschte während des Färbeprozesses auftretende Fixierung der Wollfasern, welche durch Umordnung der in der Wolle enthaltenen Disulfid-Brücken verursacht wird. Solche unerwünschten Fixierungen können sich z.B. in einer Deformation (Verflachung) der Wollgarne auf Spulen, einer Kompaktierung der Wollfasern sowie in einem Verlust des Volumens der Wolle äussern.Another advantage of the method according to the invention relates to the reduction in the setting which is achieved by the presence of a compound of the formula (1) or (1 ') in the dyebath. A setting is an undesired fixation of the wool fibers that occurs during the dyeing process, which is caused by rearrangement of the disulfide bridges contained in the wool. Such undesirable fixations can, for example, result in a deformation (flattening) of the wool yarns on bobbins, one Compacting the wool fibers as well as expressing a loss in the volume of the wool.

Der Antisetting-Effekt eines Wollschutzmittels kann z.B. in Anlehnung an A.M. Wemys und M.A. White, Proc. Ind. Japan-Australia, Joint Symp. on objective measurement, Kyoto (1985), Seite 165, bestimmt werden, indem man Rondelle aus Woll-Testgewebe ausstanzt, in der Mitte faltet und am Rand zusammennäht. Die Prüflinge werden dann in gepresstem Zustand in Gegenwart des Wollschutzmittels gefärbt, anschliessend die Gewebemuster geöffnet und jeweils ein Faden herausgezogen. Nach einer Erholungsphase in warmem Wasser wird der Winkel der Fäden gemessen. Je mehr sich das vorher zusammengepresste Garn geöffnet hat und um so mehr sich der gemessene Winkel an 180° annähert, um so besser ist der Antisetting-Effekt des Wollschutzmittels. Ein gemessener Winkel von ca. 120 bis 180° und insbesondere 140 bis 180° zeigt einen guten Anti-Setting-Effekt an.The antisetting effect of a wool protection agent can e.g. based on A.M. Wemys and M.A. White, Proc. Ind. Japan-Australia, Joint Symp. On objective measurement, Kyoto (1985), page 165, can be determined by punching rondelles out of wool test fabric, folding them in the middle and sewing them together at the edge. The test specimens are then dyed in the pressed state in the presence of the wool protection agent, the fabric samples are then opened and a thread is pulled out in each case. After a recovery period in warm water, the angle of the threads is measured. The more the previously compressed yarn has opened and the closer the measured angle approaches 180 °, the better the anti-setting effect of the wool protection agent. A measured angle of approximately 120 to 180 ° and in particular 140 to 180 ° indicates a good anti-setting effect.
