Des weiteren sind aus DE-OS 34 19 405 Fettungsmittel zur Herstellung von Leder und Pelzen bekannt, die Sulfobernsteinsäureester in Kombination mit bestimmten anionischen und/oder nichtionischen Emulgatoren enthalten. Auch mit diesen Fettungsmitteln, die in der Gerbflotte eingesetzt werden, wird eine Hydrophobierung der Leder und Pelze nicht erzielt.Furthermore, from DE-OS 34 19 405 fatliquoring agents for the production of leather and furs are known which contain sulfosuccinic acid esters in combination with certain anionic and / or nonionic emulsifiers.

Leather and furs, which are treated with such fatliquor mixtures, are distinguished by possibly less good hydrophobing properties in comparison to leather and fur, which are treated with fatliquors containing sulfosuccinic acid monoamide without sulfated, sulfonated, sulfited, sulfochlorinated and / or phosphated fat substances very high softness.
In den für das erfindungsgemäße Verfahren geeigneten Fettungsmitteln, die neben Sulfobernsteinsäuremonoamiden weitere Komponenten enthalten (Fettungsmittelgemische) liegt der Anteil an Sulfobernsteinsäuremonoamiden zwischen etwa 10 und etwa 60 Gewichtsprozent, vorzugsweise zwischen etwa 20 und etwa 50 Gewichtsprozent, jeweils bezogen auf Aktivsubstanz.In the fatliquoring agents which are suitable for the process according to the invention and which contain further components in addition to sulfosuccinic acid monoamides (fatliquor mixtures), the proportion of sulfosuccinic acid monoamides is between about 10 and about 60 percent by weight, preferably between about 20 and about 50 percent by weight, in each case based on active substance.
Die für das erfindungsgemäße Verfahren geeigneten Fettungsmittel liegen beispielsweise in Form von Pasten, wäßrigen Emulsionen oder Mikroemulsionen vor.The lubricants suitable for the process according to the invention are present, for example, in the form of pastes, aqueous emulsions or microemulsions.
Nach dem erfindungsgemäßen Verfahren werden gegebenenfalls gefärbte Leder und Pelze in wäßriger Flotte bei etwa 35 bis 70 °C, vorzugsweise bei etwa 40 bis 55 °C mit Fettungsmitteln auf Basis von Sulfobernsteinsäure monoamiden gefettet. In Abhängigkeit von den zu behandelnden Leder- und Pelztypen werden etwa 3 bis 15 Gewichtsprozent - bezogen auf Aktivsubstanz sowie auf Falz- oder Fellgewicht - an Fettungsmitteln eingesetzt. Der pH- Wert der Lickerflotte liegt zwischen etwa 4 und 8, vorzugsweise zwischen etwa 4 und 6. Der Lickerfettung kann sich eine an sich bekannte Behandlung mit einem Polyacrylatgerbstoff anschließen, bevor mit Säure, beispielsweise Ameisensäre ein pH-Wert zwischen etwa 3,8 und 4,2 eingestellt wird. Danach werden die Fettungsmittel auf Basis von Sulfobernsteinsäuremonoamiden in an sich bekannter Weise mit polyvalenten Metallsalzen, insbesondere mit Aluminium-, Chrom-, Titan- und/oder Zirkonsalzen in wäßriger Form fixiert. Die Einsatzmengen der Salze liegen zwischen etwa ein und zehn Gewichtsprozent bezogen auf Falz- oder Fellgewicht.In the process according to the invention, colored leather and furs are optionally dipped in an aqueous liquor at about 35 to 70 ° C., preferably at about 40 to 55 ° C., with degreasing agents based on sulfosuccinic acid greased monoamides. Depending on the types of leather and fur to be treated, about 3 to 15 percent by weight - based on the active substance as well as the weight of the fold or fur - is used in fatliquoring agents. The pH of the liquor liquor is between about 4 and 8, preferably between about 4 and 6. The licker lubrication can be followed by a treatment with a polyacrylate tanning agent known per se, before a pH between about 3.8 and with acid, for example formic acids 4.2 is set. Thereafter, the fatliquoring agents based on sulfosuccinic acid monoamides are fixed in a known manner with polyvalent metal salts, in particular with aluminum, chromium, titanium and / or zirconium salts in aqueous form. The amounts of salts used are between about one and ten percent by weight based on the weight of the fold or skin.
Im Rahmen des erfindungsgemäßen Verfahrens können Leder und Pelze mit Fettungsmitteln auf Basis von Sulfobernsteinsäuremonoamiden behandelt werden, indem alle Fettungsmittelbestandteile zusammen der Flotte zugesetzt werden. In manchen Fällen erweist es sich jedoch als vorteilhaft, die einzelnen Fettungsmittelbestandteile nacheinander der Flotte zuzusetzen. In Abhängigkeit vom Anteil der hydrophobierenden und/oder imprägnierenden Fettungsmittel wird eine mehr oder weniger stark ausgeprägte Wasserdichtigkeit erzielt.In the process according to the invention, leather and furs can be treated with fatliquoring agents based on sulfosuccinic acid monoamides by adding all the fatliquoring constituents together to the liquor. In some cases, however, it proves to be advantageous to add the individual fatliquor components to the liquor one after the other. Depending on the proportion of the hydrophobizing and / or impregnating greasing agents, a more or less pronounced water resistance is achieved.
Die Verwendung von Fettungsmitteln auf Basis von Sulfobernsteinsäuremonoamiden zur Hydrophobierung von Leder und Pelzen ist ein weiterer Gegenstand der Erfindung.The use of fatliquors based on sulfosuccinic acid monoamides for the hydrophobization of leather and furs is a further subject of the invention.
Vorzugsweise verwendete Fettungsmittel enthalten Sulfobernsteinsäuremonoamide in Form ihrer Alkali- und/oder Ammoniumsalze.Fatting agents preferably used contain sulfosuccinic acid monoamides in the form of their alkali and / or ammonium salts.
Fettungsmittel, die Salze der Sulfobernsteinsäuremonoamide mit ein oder zwei 12 bis 24 C-Atome, vorzugsweise mit ein oder zwei 14 bis 22 C-Atome enthaltenden gerad- und/oder verzweigtkettigen, gesättigten und/oder ungesättigten Alkylresten in den Aminkomponenten enthalten, werden besonders bevorzugt verwendet.Fatting agents which contain salts of sulfosuccinic acid monoamides with one or two 12 to 24 C atoms, preferably with one or two 14 to 22 C atoms containing straight and / or branched chain, saturated and / or unsaturated alkyl radicals in the amine components are particularly preferred used.
Im Rahmen der Erfindung können Fettungsmittel, die als einzige Komponente Sulfobernsteinsäuremonoamide enthalten, verwendet werden.In the context of the invention, fatliquoring agents which contain sulfosuccinic acid monoamides as the only component can be used.
Vorzugsweise werden jedoch Fettungsmittel verwendet, die neben Sulfobernsteinsäuremonoamiden als weitere Komponenten hydrophobierende und/oder imprägnierende Fettungsmittel und/oder Neutralöle enthalten.However, fatliquoring agents are preferably used which, in addition to sulfosuccinic acid monoamides, contain hydrophobing and / or impregnating fatliquoring agents and / or neutral oils as further components.
Geeignete hydrophobierende und/oder imprägnierende Fettungsmittel sind beispielsweise oxidierte und/oder sulfoxidierte C16-30-Kohlenwasserstoffe und/oder C32-40-Wachse, Alkylphosphate mit 12 bis 24 C-Atomen in den gerad- und/oder verzweigtkettigen,gesättigten und/oder ungesättigten Alkylresten, Polycarbonsäurepartialester wie Citronensäurepartialalkylester mit 12 bis 24 C-Atomen in den gerad- und/oder verzweigtkettigen,gesättigten und/oder ungesättigten Veresterungskomponenten und/oder Partialester von Polyalkoholen beispielsweise Sorbitan-, Glycerin- und/oder Pentaerythritfettsäureester mit 12 bis 24 C-Atomen in den gerad- und/oder verzweigtkettigen, gesättigten und/oder ungesättigten Fettsäureresten.Suitable hydrophobicizing and / or impregnating lubricants are, for example, oxidized and / or sulfoxidized C 16-30 hydrocarbons and / or C 32-40 waxes, alkyl phosphates with 12 to 24 C atoms in the straight and / or branched chain, saturated and / or unsaturated alkyl radicals, polycarboxylic acid partial esters such as partial citric acid partial alkyl esters with 12 to 24 C atoms in the straight and / or branched chain, saturated and / or unsaturated esterification components and / or partial esters of polyalcohols, for example sorbitan, glycerol and / or pentaerythritol fatty acid esters with 12 to 24 C. -Atoms in the straight and / or branched chain, saturated and / or unsaturated fatty acid residues.
Als Neutralöle eignen sich insbesondere tierische und/oder pflanzliche Fette und Öle beispielsweise Klauenöl, Fischöl, Talge, Sojaöl, Sonnenblumenöl, Palmöl und/oder Kokosöl, chlorierte und/oder nicht chlorierte Fettsäuremethylester wie chlorierter Talgfettsäuremethylester, langkettige Kohlenwasserstoffe und /oder Chlorparaffine.Suitable neutral oils are in particular animal and / or vegetable fats and oils, for example claw oil, fish oil, tallow, soybean oil, sunflower oil, palm oil and / or coconut oil, chlorinated and / or non-chlorinated fatty acid methyl esters such as chlorinated tallow fatty acid methyl ester, long-chain hydrocarbons and / or chlorinated paraffins.
Als weitere Bestandteile können die erfindungsgemäß zu verwendenden Fettungsmittel durch Sulfatierung, Sulfonierung, Sulfitierung, Sulfochlorierung oder Phosphatierung von Fetten und/oder Ölen hergestellte Fettstoffe sowie deren Mischungen enthalten. Der Anteil dieser Fettstoffe in Sulfobernsteinsäuremonoamid-haltigen Fettungsmitteln kann bis zu etwa 40 Gew.-% - bezogen auf Aktivsubstanz - betragen. Leder und Pelze, die mit solchen Fettungsmittelgemischen behandelt werden, zeichnen sich im Vergleich zu Leder und Pelzen, die mit Sulfobernsteinsäuremonoamid-haltigen Fettungsmitteln ohne sulfatierte, sulfonierte, sulfitierte, sulfochlorierte und/oder phosphatierte Fettstoffe behandelt werden, durch gegebenenfalls weniger gute Hydrophobierungseigenschaften, jedoch durch sehr hohe Weichheit aus.The fatliquors to be used according to the invention may contain, as further constituents, fat substances and mixtures thereof produced by sulfation, sulfonation, sulfitination, sulfochlorination or phosphatization of fats and / or oils. The proportion of these fatty substances in fat-releasing agents containing sulfosuccinic acid monoamide can be up to about 40% by weight, based on the active substance. Leather and furs, which are treated with such fatliquor mixtures, are distinguished by possibly less good hydrophobing properties in comparison to leather and fur, which are treated with fatliquors containing sulfosuccinic acid monoamide without sulfated, sulfonated, sulfited, sulfochlorinated and / or phosphated fat substances very high softness.
In den erfindungsgemäß zu verwendenden Fettungsmitteln, die neben Sulfobernsteinsäuremonoamiden weitere Komponenten enthalten, liegt der Anteil an Sulfobernsteinsäuremonoamiden zwischen etwa 10 und etwa 60 Gewichtsprozent, vorzugsweise zwischen etwa 20 und etwa 50 Gewichtsprozent, jeweils bezogen auf Aktivsubstanz.In the fatliquors to be used according to the invention, which contain further components in addition to sulfosuccinic acid monoamides, the proportion of sulfosuccinic acid monoamides is between about 10 and about 60 percent by weight, preferably between about 20 and about 50 percent by weight, based in each case on the active substance.
Die erfindungsgemäß zu verwendenden Fettungsmittel liegen beispielsweise in Form von Pasten, wäßrigen Emulsionen oder Mikroemulsionen vor.The fatliquors to be used according to the invention are, for example, in the form of pastes, aqueous emulsions or microemulsions.
Die erfindungsgemäßen Fettungsmittel werden von Leder und Pelzen gut aufgenommen und verteilen sich sehr gleichmäßig über den gesamten Lederquerschnitt. Des weiteren wird mit diesen eine ausgeprägte Wasserdichtigkeit der Leder und Pelze erzielt. Im Vergleich zu Leder und Pelzen, die mit Fettungsmitteln enthaltend Sulfobernsteinsäureester gefettet werden, weisen Leder und Pelze, die mit den erfindungsgemäßen Fettungsmitteln behandelt wurden, einen deutlich verzögerten Wasserdurchtritt sowie eine verringerte Wasseraufnahme auf. Die Färbung der mit den erfindungsgemäßen Fettungsmitteln behandelten Leder und Pelze ist im Vergleich zu Leder und Pelzen, die mit Fettungsmitteln enthaltend Sulfobernsteinsäuremonoester behandelt wurden, gleichmäßiger und brillanter.The fatliquoring agents according to the invention are well absorbed by leather and furs and are distributed very evenly over the entire leather cross section. Furthermore, the leather and furs have a pronounced waterproofness. Compared to leather and furs, which are greased with fatty agents containing sulfosuccinic acid esters, leather and furs, which have been treated with the greasing agents according to the invention, have a significantly delayed passage of water and a reduced water absorption. The coloration of the leather and furs treated with the fatliquoring agents according to the invention is more uniform and brilliant than that of leather and fur that has been treated with fatliquoring agents containing sulfosuccinic acid monoesters.
