Definitions
- the invention relates to a process for the fat filling of fur skins and the use of certain monocarboxylic acid partial esters for the fat filling of fur skins.
- Wool fat as such is difficult to incorporate into fur skins due to its pasty consistency. It is therefore usually liquefied with mineral oils, which considerably improves the penetration of the wool fat into the fur skins.
- the fur skins are first subjected to an extraction with solvents, mineral oils being extracted practically quantitatively and wool fat due to its poorer solubility only to a small extent.
- the fur skins are then cleaned to remove adhering wool fat from the skins.
- the object on which the invention is based was therefore to develop constant-quality whale oils which give fur skins consistently good performance properties. Furthermore, the whale oils to be developed should not have their own smell, be liquid and be easy to incorporate into fur skins.
- the invention relates to a process for the churning of fur skins, wherein the fur skins are drummed at 30 to 50 ° C. with chalk oils containing C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters and then the monocarboxylic acid partial adhering to the fur skins can be removed in a manner known per se by refining.
- Another object of the present invention is the use of C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters for the fat greasing of fur skins.
- the whale oils according to the invention can contain non-volatile hydrocarbons, for example mineral oils and / or alkylbenzenes, the content of hydrocarbons resulting from the desired viscosity and from the desired penetration capacity of the whale oils to be used.
- non-volatile hydrocarbons for example mineral oils and / or alkylbenzenes
- Most of the liquid carboxylic acid partial esters to be used according to the invention already have such a good penetration ability into the fur skins that there is no need to add hydrocarbons.
- the whale oils according to the invention can contain complex-active emulsifiers, for example C 8-22 citric acid alkyl esters and / or phosphoric acid esters of alkoxylated C 8-22 fatty alcohols, and / or nonionic emulsifiers, such as alkoxylated C 8-22 fatty alcohols.
- the monocarboxylic acid partial esters to be used in whale oils according to the invention can be prepared in a manner known per se by esterifying linear and / or branched-chain, saturated and / or unsaturated C 12-18 carboxylic acids with diglycerol and / or triglycerol in the presence of catalysts, for example sulfuric acid, p-toluenesulfonic acid or Caustic soda, with and without
- Suitable C 12-18 carboxylic acids of natural and / or synthetic origin are, for example, lauric acid, myristic acid, palmitic acid, C 16 gueretic acid, pamitolic acid, stearic acid, 2-methylheptadecanoic acid, oleic acid, C 20 gueretic acid.
- Guerbet acids can be prepared from fatty alcohols, which are converted into Guerbet alcohols in the presence of alkaline catalysts and then oxidized to the corresponding Guerbet acids (G. Dieckelmann and HJ Heinz: "The Basics of Industrial Oleochemistry, pp. 145-147, Peter Pomp GmbH 1988).
- the monocarboxylic acid partial esters are used in amounts of 50 to 400 g per fur skin.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Walkfettung von Pelzfellen sowie die Verwendung bestimmter Monocarbonsäurepartialester zur Walkfettung von Pelzfellen.The invention relates to a process for the fat filling of fur skins and the use of certain monocarboxylic acid partial esters for the fat filling of fur skins.
Für die Fettung von Pelzfellen in Hammerwalken und ähnlichen für diesen Zweck konzipierten Einrichtungen werden sogenannte Walköle eingesetzt, die als Hauptbestandteile Wollfett und Mineralöle enthalten ("Rauchwarenherstellung und Pelzkonfektion", Seite 123, VEB Fachbuchverlag Leipzig, 1970).For the greasing of fur in hammer whales and similar devices designed for this purpose, so-called fulling oils are used which contain wool fat and mineral oils as main components ("Tobacco production and fur making", page 123, VEB Fachbuchverlag Leipzig, 1970).
Wollfett als solches läßt sich aufgrund seiner pastösen Konsistenz nur schwer in Pelzfelle einarbeiten. Es wird daher üblicherweise mit Mineralölen verflüssigt, wodurch die Penetration des Wollfettes in die Pelzfelle erheblich verbessert wird.Wool fat as such is difficult to incorporate into fur skins due to its pasty consistency. It is therefore usually liquefied with mineral oils, which considerably improves the penetration of the wool fat into the fur skins.
Nach dem Walkprozeß mit wollfetthaltigen Walkölen und gegebenenfalls Dünnschneiden werden die Pelzfelle zunächst einer Extraktion mit Lösungsmitteln unterworfen, wobei Mineralöle praktisch quantitativ und Wollfett aufgrund seiner schlechteren Löslichkeit nur zu geringen Teilen extrahiert wird. Anschließend werden die Pelzfelle geläutert, um anhaftendes Wollfett aus den Fellen zu entfernen.After the milling process with wool oils containing wool oils and possibly thin cutting, the fur skins are first subjected to an extraction with solvents, mineral oils being extracted practically quantitatively and wool fat due to its poorer solubility only to a small extent. The fur skins are then cleaned to remove adhering wool fat from the skins.
Durch die Walkfettung mit wollfetthaltigen Walkölen erhalten Pelzfelle günstige Gebrauchseigenschaften, insbesondere Weichheit, Zügigkeit und Griffigkeit. Die Verwendung von Wollfett in Walkölen ist jedoch mit einigen Nachteilen verbunden: die erzielten Gebrauchseigenschaften gewalkter Pelzfelle hängen von dem in der Qualität immer schwankenden Naturprodukt Wollfett ab. Um Pelzfelle mit gleichbleibend guten Gebrauchseigenschaften zu erhalten, ist es daher erforderlich, das Mischungsverhältnis Wollfett zu Mineralölen und/oder die Walkdauer der Qualität des eingesetzten Wollfettes anzupassen. Die Notwendigkeit, Mineralöle in wollfetthaltigen Walkölen einzusetzen, erfordert darüberhinaus eine Extraktion der Mineralöle mit Lösungsmitteln, beispielsweise halogenierten Kohlenwasserstoffen, wodurch sich Entsorgungsprobleme der lösungsmittelhaltigen Extraktionsrückstände ergeben. Des weiteren besitzen Pelzfelle, die mit wollfetthaltigen Walkölen behandelt wurden, immer den typischen Wollfettgeruch.Because of the wool greasing with wool oils containing wool, fur has good usage properties, especially softness, elasticity and grip. The use of wool fat in whale oils However, there are some disadvantages: the performance characteristics of milled fur skins depend on the natural product wool fat, which always fluctuates in quality. In order to obtain fur skins with consistently good usage properties, it is therefore necessary to adjust the mixing ratio of wool fat to mineral oils and / or the milling duration to the quality of the wool fat used. The need to use mineral oils in woolen-containing whale oils also requires extraction of the mineral oils with solvents, for example halogenated hydrocarbons, which leads to problems with the disposal of the solvent-containing extraction residues. Furthermore, fur skins that have been treated with wool oils containing whale oils always have the typical smell of wool fat.
Die der Erfindung zugrunde liegende Aufgabe bestand daher in der Entwicklung von Walkölen konstanter Qualität, die Pelzfellen gleichbleibend gute Gebrauchseigenschaften verleihen. Des weiteren sollen die zu entwickelnden Walköle keinen Eigengeruch besitzen, flüssig sein und sich gut in Pelzfellen einarbeiten lassen.The object on which the invention is based was therefore to develop constant-quality whale oils which give fur skins consistently good performance properties. Furthermore, the whale oils to be developed should not have their own smell, be liquid and be easy to incorporate into fur skins.
Es wurde nun gefunden, daß die an die zu entwickelnden Walköle gestellten hohen Anforderungen von bestimmten C12-18-Monocarbonsäurediglycerinpartialestern und/oder C12-18-Monocarbonsäuretriglycerinpartialestern erfüllt werden.It has now been found that the high demands placed on the whale oils to be developed are met by certain C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters.
Gegenstand der Erfindung ist ein Verfahren zur Walkfettung von Pelzfellen, wobei die Pelzfelle bei 30 bis 50 °C mit Walkölen, enthaltend C12-18-Monocarbonsäurediglycerinpartialester und/oder C12-18-Monocarbonsäuretriglycerinpartialester gewalkt werden und anschließend die an den Pelzfellen oberflächlich anhaftenden Monocarbonsäurepartialester in an sich bekannter Weise durch Läutern entfernt werden.The invention relates to a process for the churning of fur skins, wherein the fur skins are drummed at 30 to 50 ° C. with chalk oils containing C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters and then the monocarboxylic acid partial adhering to the fur skins can be removed in a manner known per se by refining.
Ein weiterer Gegenstand der vorliegenden Erfindung ist die Verwendung von C12-18-Monocarbonsäurediglycerinpartialestern und/oder C12-18-Monocarbonsäurtriglycerinpartialestern zur Walkfettung von Pelzfellen.Another object of the present invention is the use of C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters for the fat greasing of fur skins.
Die erfindungsgemäßen Walköle können nichtflüchtige Kohlenwasserstoffe, beispielsweise Mineralöle und/oder Alkylbenzole, enthalten, wobei sich der Gehalt an Kohlenwasserstoffen aus der gewünschten Viskosität und aus dem gewünschten Penetrationsvermögen der einzusetzenden Walköle ergibt. Die meisten erfindungsgemäß einzusetzenden flüssigen Carbonsäurepartialester besitzen bereits ein so gutes Penetrationsvermögen in die Pelzfelle, daß sich ein Zusatz von Kohlenwasserstoffen erübrigt. Ferner können die erfindungsgemäßen Walköle komplexaktive Emulgatoren, zum Beispiel Citronensäure-C8-22-alkylester und/oder Phosphorsäureester alkoxylierter C8-22-Fettalkohole, und/oder nichtionische Emulgatoren, wie alkoxylierte C8-22-Fettalkohole, enthalten.The whale oils according to the invention can contain non-volatile hydrocarbons, for example mineral oils and / or alkylbenzenes, the content of hydrocarbons resulting from the desired viscosity and from the desired penetration capacity of the whale oils to be used. Most of the liquid carboxylic acid partial esters to be used according to the invention already have such a good penetration ability into the fur skins that there is no need to add hydrocarbons. Furthermore, the whale oils according to the invention can contain complex-active emulsifiers, for example C 8-22 citric acid alkyl esters and / or phosphoric acid esters of alkoxylated C 8-22 fatty alcohols, and / or nonionic emulsifiers, such as alkoxylated C 8-22 fatty alcohols.
Die erfindungsgemäß in Walkölen einzusetzenden Monocarbonsäurepartialester können in an sich bekannter Weise durch Veresterung von linearen und/oder verzweigtkettigen, gesättigten und/oder ungesättigten C12-18-Carbonsäuren mit Diglycerin und/oder Triglycerin in Gegenwart von Katalysatoren, beispielsweise Schwefelsäure, p-Toluolsulfonsäure oder Natronlauge, mit und ohneThe monocarboxylic acid partial esters to be used in whale oils according to the invention can be prepared in a manner known per se by esterifying linear and / or branched-chain, saturated and / or unsaturated C 12-18 carboxylic acids with diglycerol and / or triglycerol in the presence of catalysts, for example sulfuric acid, p-toluenesulfonic acid or Caustic soda, with and without
Lösungsmittel bei erhöhten Temperaturen hergestellt werden (Drew Myers: "Surfactant Science and Technology", Seiten 69 bis 71, VCH Verlagsgesellschaft mbH, Weinheim 1988; Fette, Seifen, Anstrichmittel 82, 93 (1980); J. Am. Oil Chem. Soc. 66, 153 (1989)). Geeignete C12-18-Carbonsäuren natürlichen und/oder synthetischen Ursprungs sind beispielsweise Laurinsäure, Myristinsäure, Palmitinsäure, C16-Guerbetsäure, Pamitoleinsäure, Stearinsäure, 2-Methylheptadecansäure, Ölsäure, C20-Guerbetsäure. Guerbetsäuren können aus Fettalkoholen hergestellt werden, die in Gegenwart alkalischer Katalysatoren in Guerbetalkohole überführt und anschließend zu den entsprechenden Guerbetsäuren oxidiert werden (G. Dieckelmann und H. J. Heinz: "The Basics of Industrial Oleochemistry, S. 145 - 147, Peter Pomp GmbH 1988).Solvents are produced at elevated temperatures (Drew Myers: "Surfactant Science and Technology", pages 69 to 71, VCH Verlagsgesellschaft mbH, Weinheim 1988; Fette, Seifen, Anstrichmittel 82 , 93 (1980); J. Am. Oil Chem. Soc. 66, 153 (1989)). Suitable C 12-18 carboxylic acids of natural and / or synthetic origin are, for example, lauric acid, myristic acid, palmitic acid, C 16 gueretic acid, pamitolic acid, stearic acid, 2-methylheptadecanoic acid, oleic acid, C 20 gueretic acid. Guerbet acids can be prepared from fatty alcohols, which are converted into Guerbet alcohols in the presence of alkaline catalysts and then oxidized to the corresponding Guerbet acids (G. Dieckelmann and HJ Heinz: "The Basics of Industrial Oleochemistry, pp. 145-147, Peter Pomp GmbH 1988).
Die Monocarbonsäurepartialester werden in Mengen von 50 bis 400 g pro Pelzfell eingesetzt.The monocarboxylic acid partial esters are used in amounts of 50 to 400 g per fur skin.
Die Walkfettung wird nach der Gerbung der Pelzfelle beispielsweise in einer Hammer- oder Kurbelwalke durchgeführt. Die Walköle werden entweder vor dem Walken auf die Felle aufgetragen oder direkt beim Walken zugegeben. Die Walkzeit liegt üblicherweise zwischen 1 und 3 Stunden. Nach dem Walkprozeß werden die Felle in an sich bekannter Weise dünngeschnitten - sofern nicht bereits gegerbte, dünngeschnittene Pelzfelle eingesetzt werden - und in einer Läutertrommel mit Sägespänen, die mit Wasser und Netzmitteln angefeuchtet sind, geläutert, um oberflächlich anhaftende Carbonsäurepartialester aus den Fellen zu entfernen.After the fur has been tanned, the greasing is carried out, for example, in a hammer or crank roller. The whale oils are either applied to the skins before drumming or added directly when drumming. The walking time is usually between 1 and 3 hours. After the milling process, the skins are thinly cut in a manner known per se - unless tanned, thinly cut fur skins are already used - and refined in a refining drum with sawdust, which are moistened with water and wetting agents, in order to remove superficially adhering carboxylic acid partial esters from the skins.
Die erfindungsgemäßen Walköle sind flüssig und besitzen ein Wasseraufnahme- bzw. Emulgiervermögen, das einer überdurchnittlichen Wollfettqualität entspricht. Des weiteren haben die meisten Carbonsäurepartialester bereits ein so gutes Penetrationsvermögen in die Felle, daß sich die Mitverwendung von Kohlenwasserstoffen, beispielsweise Mineralölen und/oder Alkylbenzolen, erübrigt. Wird die Walkfettung mit Walkölen durchgeführt, die keine oder nur geringe Mengen an Mineralölen enthalten, so erübrigt sich die Lösungsmittelextraktion vor dem Läuterungsprozeß und es entfallen die Entsorgungsprobleme lösungsmittelhaltiger Extraktionsrückstände.The whale oils according to the invention are liquid and have a water absorption or emulsification capacity which corresponds to an above-average wool fat quality. Furthermore, most carboxylic acid partial esters already have such good penetration ability in the skins that the use of hydrocarbons, for example mineral oils and / or alkylbenzenes, is unnecessary. If the whale greasing is carried out with whale oils that contain no or only small amounts of mineral oils, there is no need for solvent extraction before the refining process and the disposal problems of solvent-containing extraction residues are eliminated.
Pelzfelle, die mit carbonsäurepartialesterhaltigen Walkölen gefettet wurden, sind sehr weich und geschmeidig, besitzen im Vergleich zu Pelzfellen, die mit Wollfett behandelt wurden, einen deutlich besseren Geruch sowie sehr gute Lichtechtheits- und Wärmevergilbungseigenschaften.Fur skins that have been greased with whale oils containing carboxylic acid partial esters are very soft and supple, have a significantly better odor and very good light-fastness and heat yellowing properties compared to fur skins that have been treated with wool grease.
Mit den erfindungsgemäßen Walkölen lassen sich auf allen Pelzfelltypen, beispielsweise Kaninchenfellen, Nerzfellen, Bisamfellen und Nutriafellen, gute Gebrauchseigenschaften erzielen.With the whale oils according to the invention, good performance properties can be achieved on all types of fur, for example rabbit fur, mink fur, muskrat and Nutria fur.

Pro Pelzfell wurden 200 g Walköl eingesetzt. Die Walkzeit betrug 2 Stunden und die Walktemperatur 33 bis 40 °C. Anschließend wurden die Pelzfelle über Nacht abgelagert und anschließend 24 Stunden hängegetrocknet.200 g of whale oil were used per fur. The milling time was 2 hours and the mill temperature 33 to 40 ° C. The fur skins were then deposited overnight and then dried for 24 hours.
Zur Weiterverarbeitung wurden die mit einem der Walköle A, B oder C behandelten Pelzfelle in einer Läutertrommel mit Sägespänen, die mit Wasser und etwas Netzmittel angefeuchtet waren, eine Stunde geläutert. Danach wurden die gebrauchten Sägespäne durch frische, wiederum mit Wasser und Netzmittel angefeuchtete Sägespäne ersetzt und eine Stunde geläutert. Danach wurden die gebrauchten Sägespäne durch trockene ersetzt und eine weitere Stunde geläutert.For further processing, the fur skins treated with one of the whale oils A, B or C were refined in a refining drum with sawdust moistened with water and some wetting agent for one hour. Then the used sawdust was replaced by fresh, again sawdust moistened with water and wetting agent and cleaned for one hour. The used sawdust was then replaced by dry one and refined for another hour.
Die mit dem handelsüblichen Walköl behandelten Pelzfelle wurden in einer Böwe-Entfettungsanlage in einem geschlossenen System 2 x 3 Minuten mit Perchlorethylen extrahiert und anschließend in einer Läutertrommel mit Sägespänen, die mit Wasser und etwas Netzmittel angefeuchtet waren, 2 Stunden geläutert.The fur skins treated with the commercial whale oil were extracted in a closed system in a Böwe degreasing system in a closed system 2 x 3 minutes with perchlorethylene and then refined in a refining drum with sawdust which had been moistened with water and a little wetting agent for 2 hours.
Nach dem Läuterungsprozeß wurden die mit einem der Walköle A bis D behandelten Pelzfelle in eine Schütteltrommel gegeben und innerhalb von 30 Minuten von den an den Fellen anhaftenden Sägespänen befreit. Nach dem Strecken auf einer Kürschnerbank wurden die Pelzfelle in einer Läutertrommel mit trockenen Sägespänen eine Stunde geläutert und anschließend in einer Schütteltrommel innerhalb von 30 Minuten von anhaftenden Sägespänen befreit.After the refining process, the fur skins treated with one of the whale oils A to D were placed in a shaking drum and the sawdust adhering to the skins was removed within 30 minutes. After stretching on a furrier's bench, the fur skins were refined with dry sawdust in a refining drum for one hour and then removed from adhering sawdust in a shaking drum within 30 minutes.
