Abstract

Wetting agents are described for a mercerising and/or alkalising treatment, containing alkali metal and/or ammonium salts of 2-ethylhexyl sulphate and a mixture of end group capped polyethers, with or without trialkyl phosphates.

Description

Die Erfindung betrifft Mercerisier- und/oder Laugiernetzmittel, die Alkali- und/oder Ammoniumsalze von 2-Ethylhexylsulfat, endgruppenverschlossene Polyether und gegebenenfalls Trialkylphosphate enthalten.The invention relates to mercerizing and / or lye wetting agents which contain alkali and / or ammonium salts of 2-ethylhexyl sulfate, end group-capped polyethers and optionally trialkyl phosphates.

Das Mercerisieren und Laugieren von Baumwolle, d. h. die Behandlung von Zellulose mit Laugen unterschiedlicher Konzentrationen dient dem Zweck, den Fasern bessere Glanzeffekte, ein gesteigertes Aufnahmevermögen für Farbstoffe, größere Reißfestigkeiten und einen weicheren, fülligeren Griff zu verleihen. Die in der Praxis verwendete konzentrierte Natronlauge besitzt jedoch kein großes Netzvermögen. Außerdem wird das Netzen durch die an den Zellulosefasern anhaftenden hydrophoben Stoffe stark erschwert. Zur Erzielung einer raschen und gleichmäßigen Reaktion der Lauge mit der Zellulose werden daher in vielen Fällen den Mercerisier- und/oder Laugierflotten Netzmittel zugesetzt (Chwala/ Anger : "Handbuch der Textilhilfsmittel" Seiten 347 - 350, 1977).Mercerizing and leaching cotton, i.e. H. the treatment of cellulose with lyes of different concentrations serves the purpose of giving the fibers better gloss effects, an increased absorption capacity for dyes, greater tear strengths and a softer, fuller feel. However, the concentrated sodium hydroxide solution used in practice does not have a large wetting power. In addition, wetting is made very difficult by the hydrophobic substances adhering to the cellulose fibers. In order to achieve a rapid and uniform reaction of the lye with the cellulose, wetting agents are therefore added to the mercerizing and / or leaching liquors in many cases (Chwala / Anger: "Handbook of Textile Aids" pages 347-350, 1977).

Neben einem guten Netzvermögen sollen die Netzmittel kein Schäumen in den Laugen verursachen, innerhalb eines großen Alkalikonzentrationsbereiches stabil sein und biologisch sehr gut abgebaut werden. Diese hohen Anforderungen werden jedoch von den meisten bekannten Mercerisier- und/oder Laugiernetzmitteln nicht in zufriedenstellender Weise erfüllt. So neigen beispielsweise die als Netzmittel häufig verwendeten Salze von 2-Ethylhexylsulfat in Mercerisier- und/oder Laugierflotten zu starker Schaumentwicklung.In addition to good wetting ability, the wetting agents should not cause foaming in the alkalis, should be stable within a large alkali concentration range and should be very well biodegraded. However, these known requirements are not satisfactorily met by most known mercerizing and / or lye wetting agents. For example, the salts of 2-ethylhexyl sulfate that are frequently used as wetting agents tend to be in mercerising and / or lye liquors to excessive foaming.

In DE-A-12 45 898 werden Gemische aus verzweigtkettigen Carbonsäureestern, Phosphorsäureestern von aliphatischen Alkoholen, Fettsäuren oder Seifen und alkoxylierte Verbindungen oder Alkylschwefelsäureester als schaumarme Netzmittel beschrieben. Aus dem Chemical Abstract Referat CA 93, 115887 g - (1980) ist ferner bekannt, daß Fettalkohole, alkoxyliert mit 20 Mol Ethylenoxid in Kombination mit 2-Ethylhexyl-Natriumsulfat das Netzvermögen von Mercerisierflotten verbessern und die Schaumentwicklung in diesen Flotten reduzieren.DE-A-12 45 898 describes mixtures of branched-chain carboxylic acid esters, phosphoric acid esters of aliphatic alcohols, fatty acids or soaps and alkoxylated compounds or alkylsulfuric acid esters as low-foaming wetting agents. From Chemical Abstract Unit CA 93 , 115887 g - (1980) it is also known that fatty alcohols, alkoxylated with 20 moles of ethylene oxide in combination with 2-ethylhexyl sodium sulfate, improve the wetting ability of mercerizing liquors and reduce the foaming in these liquors.

Aus DE-A-33 15 951, DE-A-37 27 378 und DE-A-38 00 490 sind endgruppenverschlossene Alkylalkoholethoxylate als schaumdrückende Zusätze in schaumarmen Reinigungsmitteln bekannt.DE-A-33 15 951, DE-A-37 27 378 and DE-A-38 00 490 end-capped alkyl alcohol ethoxylates are known as foam-suppressing additives in low-foam cleaning agents.

Die Aufgabe der Erfindung bestand in der Entwicklung von schaumarmen, alkalistabilen und biologisch gut abbaubaren Mercerisier- und/oder Laugiernetzmitteln mit sehr gutem Schrumpfnetzvermögen.The object of the invention was to develop low-foaming, alkali-stable and readily biodegradable mercerizing and / or lye wetting agents with very good shrink wetting properties.

Überraschenderweise wurde gefunden, daß Netzmittel, die Alkali-und /oder Ammoniumsalze von 2-Ethylhexylsulfat, spezielle endgruppenverschlossene Polyether und gegebenenfalls Trialkylphosphate enthalten, die an sie gestellten hohen Anforderungen weitgehend erfüllen.Surprisingly, it was found that wetting agents which contain alkali and / or ammonium salts of 2-ethylhexyl sulfate, special end group-capped polyethers and optionally trialkyl phosphates largely meet the high demands placed on them.

Chem. 64, 213 - 220 (1952)) werden einer Oxalkylierung mit Ethylenoxid, Propylenoxid und/oder Butylenoxid, vorzugsweise einer Ethoxylierung unterworfen ("Chemische Technologie" Band 7, Seite 131 - 132, Carl-Hanser Verlag, München-Wien (1986)) und anschließend vorzugsweise mit Alkylhalogeniden mit 1 bis 6 C-Atomen, beispielsweise Methylchlorid, Ethylchlorid, Propylchlorid, Butylchlorid, Butylbromid, Pentylchlorid und/oder Hexylchlorid bei Temperaturen zwischen 60 und 140 °C umgesetzt (DE-OS 37 44 525). Beispiele für die zur Herstellung von Guerbetalkoholen benötigten Alkohole sind Capryl-, Caprin-, Lauryl-, Myristyl-, Cetyl-, Stearylalkohol sowie Mischungen dieser Alkohole.The end group-capped polyethers of the general formula A can be obtained by known processes: Guerbet alcohols, prepared by reacting saturated, primary alcohols with 1-20 C atoms in the presence of alkali (see, for example, in Angew. Chem. 64 , 213-220 (1952) ) are subjected to an oxyalkylation with ethylene oxide, propylene oxide and / or butylene oxide, preferably ethoxylation ("Chemical Technology" Volume 7, pages 131-132, Carl-Hanser Verlag, Munich-Vienna (1986)) and then preferably with alkyl halides with 1 to 6 carbon atoms, for example methyl chloride, ethyl chloride, propyl chloride, butyl chloride, butyl bromide, pentyl chloride and / or hexyl chloride, are reacted at temperatures between 60 and 140 ° C. (DE-OS 37 44 525). Examples of the alcohols required for the production of Guerbet alcohols are caprylic, capric, lauryl, myristyl, cetyl, stearyl alcohol and mixtures of these alcohols.

Die endgruppenverschlossenen Polyether der allgemeinen Formel B lassen sich ebenfalls nach literaturbekannten Verfahren herstellen. Als Edukte werden aliphatische, gesättigte und/oder ungesättigte Alkohole natürlichen und/oder synthetischen Ursprungs mit 8 - 22 C-Atomen beispielsweise Octyl-, Decyl-, Dodecyl-, Myristyl-, Cetyl-, Stearyl-, Oleyl-, Linoleyl-, Behenyl-, Erucaalkohol oder Mischungen dieser Alkohole eingesetzt. Bevorzugt werden Alkohole mit 12 - 18 C-Atomen, beispielsweise Lauryl-, Myristyl-, Cetyl-, Stearyl-, Oleylalkohol sowie Mischungen dieser Alkohole. Die Oxalkylierung dieser Alkohole mit Ethylenoxid, Propylenoxid und/oder Butylenoxid, vorzugsweise mit Ethylenoxid werden nach bekannten großtechnischen Verfahren durchgeführt (siehe beispielsweise im "Chemischen Technologie" Band 7, Seite 131 - 132, Carl-Hanser Verlag, München-Wien (1986)). Anschliessend werden die oxalkylierten Alkohole in an sich bekannter Weise vorzugsweise mit Alkylhalogeniden mit 1 - 6 C-Atomen, beispielsweise Methylchlorid, Ethylchlorid, Propylchlorid, Butylchlorid, Butylbromid, Pentylchlorid und/oder Hexylchlorid zu den endgruppenverschlossenen Polyethern umgesetzt.The end group-capped polyethers of the general formula B can also be prepared by processes known from the literature. The educts are aliphatic, saturated and / or unsaturated alcohols of natural and / or synthetic origin with 8-22 carbon atoms, for example octyl, decyl, dodecyl, myristyl, cetyl, stearyl, oleyl, linoleyl, behenyl -, Eruca alcohol or mixtures of these alcohols used. Alcohols with 12-18 C atoms, for example lauryl, myristyl, cetyl, stearyl, oleyl alcohol and mixtures of these alcohols, are preferred. The alkoxylation of these alcohols with ethylene oxide, propylene oxide and / or butylene oxide, preferably with ethylene oxide, is carried out by known industrial processes (See, for example, in "Chemical Technology" Volume 7, pages 131-132, Carl-Hanser Verlag, Munich-Vienna (1986)). The alkoxylated alcohols are then reacted in a manner known per se, preferably with alkyl halides having 1 to 6 carbon atoms, for example methyl chloride, ethyl chloride, propyl chloride, butyl chloride, butyl bromide, pentyl chloride and / or hexyl chloride, to give the end group-capped polyethers.

Die gewünschtenfalls in den erfindungsgemäßen Netzmitteln enthaltenen Trialkylphosphate werden in an sich bekannter Weise beispielsweise durch Umsetzung von Phosphoroxychlorid mit Alkylalkoholen hergestellt (Chem. and Ind. 1962, 1032 - 1035). Als Alkylalkohole werden beispielsweise Methanol, Ethanol, Propanol, n-Butanol, n-Pentanol oder n-Hexanol eingesetzt. Vorzugsweise enthalten die erfindungsgemäßen Netzmittel 0,5 bis 5 Gew.-% Trialkylphosphate.The trialkyl phosphates optionally contained in the wetting agents according to the invention are prepared in a manner known per se, for example by reacting phosphorus oxychloride with alkyl alcohols (Chem. And Ind. 1962 , 1032-1035). As alkyl alcohols, for example, methanol, ethanol, propanol, n-butanol, n-pentanol or n-hexanol are used.

Die Herstellung der erfindungsgemäßen Netzmittel erfolgt bei 18 bis 50 °C, indem man die einzelnen Komponenten, gegebenenfalls nach Aufschmelzen, zu einer homogenen Lösung verrührt.The wetting agents according to the invention are prepared at 18 to 50 ° C. by stirring the individual components, if appropriate after melting, to give a homogeneous solution.

Die erfindungsgemäßen Netzmittel, die in Form wäßriger Lösungen vorliegen, zeichnen sich durch ein hohes Schrumpfnetzvermögen bei gleichzeitiger Schaumarmut aus. Des weiteren sind sie sehr gut biologisch abbaubar. Die erfindungsgemäßen Netzmittel enthalten keine oder nur geringe Mengen an Lösungsmitteln wie Polyalkohole, beispielsweise Hexylenglycol und/oder Butylenglycol.The wetting agents according to the invention, which are in the form of aqueous solutions, are notable for high shrink wetting capacity and low foaming. Furthermore, they are very easily biodegradable. The wetting agents according to the invention contain no or only small amounts of solvents such as polyalcohols, for example hexylene glycol and / or butylene glycol.

Aufgrund ihrer Stabilität in einem weiten Alkalikonzentrationsbereich lassen sich die erfindungsgemäßen Netzmittel sowohl zum Mercerisieren als auch zum Laugieren von beispielsweise zellulosehaltigen Webwaren, Wirkwaren und/oder Garnen verwenden. In den Mercerisier- und/oder Laugierflotten liegt der Gehalt der erfindungsgemäßen Netzmittel zwischen 2 und 12 g/l Flotte.Because of their stability in a wide range of alkali concentrations, the wetting agents according to the invention can be used Use both for mercerizing and for leaching, for example, cellulose-containing woven goods, knitwear and / or yarns.
