Abstract
Description
Aus DE-OS 16 69 347 ist ein Verfahren zum Fetten von Leder bekannt unter Verwendung von in Wasser emulgierbaren Sulfobernsteinsäureestern, die erhalten worden sind durch Veresterung von alkoholische Hydroxylgruppen sowie lipophile Reste enthaltenden fett- oder ölartigen Verbindungen mit Maleinsäureanhydrid und Umsetzung des Veresterungsproduktes mit einer dem eingesetzten Maleinsäureanhydrid annähernd äquimolaren Menge eines Sulfits oder Bisulfits. Die Anwendung derartiger Verbindungen beschränkt sich jedoch auf die Lederfettung. Ein Einsatz während der Chrom- oder Aluminiumgerbung bzw. -Nachgerbung ist wegen der mangelhaften Emulsionsbeständigkeit der Sulfobernsteinsäureester gegenüber Chrom- oder Aluminiumsalzen nicht möglich.From DE-OS 16 69 347 a method for greasing leather is known using water-emulsifiable sulfosuccinic acid esters, which have been obtained by esterification of alcoholic hydroxyl groups and lipophilic residues containing fatty or oily compounds with maleic anhydride and reaction of the esterification product with a maleic anhydride used approximately equimolar amount of a sulfite or bisulfite. However, the use of such compounds is limited to leather greasing. Use during chrome or aluminum tanning or post-tanning is not possible due to the poor emulsion resistance of the sulfosuccinic acid esters to chrome or aluminum salts.
Es wurde nun die überraschende Feststellung gemacht, daß Sulfobernsteinsäureester auch während der Chrom- oder Aluminiumgerbung bzw. -nachgerbung in der Gerbflotte als Fettungsmittel bei der Herstellung von Leder und Pelzen eingesetzt werden können, wenn man sie mit bestimmten anionischen oder nichtionischen Emulgatoren kombiniert.It has now been made the surprising finding that sulfosuccinic acid esters can also be used as greasing agents in the production of leather and furs during the chrome or aluminum tanning or retanning in the tanning liquor if they are combined with certain anionic or nonionic emulsifiers.
Gegenstand der Erfindung ist somit ein Verfahren zur Herstellung von Leder und Pelzen durch Chrom- oder Aluminiumgerbung bzw. -nachgerbung, gekennzeichnet durch die Verwendung einer Kombination aus
- (A) 90 bis 40 Gewichtsprozent Sulfobernsteinsäureestern, die als Veresterungskomponente Ci2-C24-Fettreste enthalten und die in Form ihrer Salze vorliegen, und
- (B) 10 bis 60 Gewichtsprozent nichtionischen und/oder anionischen Emulgatoren aus der Gruppe der Alkylenoxidaddukte an C8-C20-Fettalkohole, -Alkylphenole, -Fettsäuren oder -Fettsäurealkanolamide und deren Schwefelsäureester in Form ihrer Alkali-, Ammonium- oder Aminsalze
in einer Gesamtmenge von 0,1 bis 6,0 Gewichtsprozent, bezogen auf Blößen- bzw. Falzgewicht, als Fettungsmittel in der Gerbflotte.The invention thus relates to a process for the production of leather and furs by chrome or aluminum tanning or retanning, characterized by the use of a combination of
- (A) 90 to 40 percent by weight of sulfosuccinic acid esters which contain as esterifying component C i2 -C 24 fatty residues, and are in the form of their salts, and
- (B) 10 to 60 percent by weight of nonionic and / or anionic emulsifiers from the group of the alkylene oxide adducts with C 8 -C 20 fatty alcohols, alkylphenols, fatty acids or fatty acid alkanolamides and their sulfuric acid esters in the form of their alkali metal, ammonium or amine salts
in a total amount of 0.1 to 6.0 percent by weight, based on the weight of the skin or seam, as a fatliquor in the tanning liquor.
Das Verhältnis der Komponenten (A): (B) in der Gerbflotte beträgt vorzugsweise 85 : 15-50 : 50 Gewichtsprozent. Die Komponenten können der Flotte getrennt oder in Form eines konfektionierten Produktes zugesetzt werden.The ratio of components (A): (B) in the tanning liquor is preferably 85: 15-50: 50 percent by weight. The components can be added to the fleet separately or in the form of a made-up product.
Die Herstellung der Sulfobernsteinsäureester (A) erfolgt in bekannter Weise durch Veresterung von Maleinsäureanhydrid mit 1 bis 2 Äquivalenten der gewünschten Veresterungskomponente und anschließende Umsetzung mit einer dem Maleinsäureanhydrid annähernd äquivalenten Menge eines Sulfits oder Bisulfits. Als Veresterungskomponente kommen Fettreste mit 12 bis 24 C-Atomen sowie Hydroxylgruppen enthaltende Verbindungen in Betracht.The sulfosuccinic acid esters (A) are prepared in a known manner by esterification of maleic anhydride with 1 to 2 equivalents of the desired esterification component and subsequent reaction with an amount of a sulfite or bisulfite which is approximately equivalent to the maleic anhydride. Fat residues with 12 to 24 carbon atoms and compounds containing hydroxyl groups are suitable as esterification components.
Die Fettreete können gesättigt oder ungesättigt, gerad- oder verzweigtkettig sein. Sie können sich herleiten von Fettalkoholen, durch Oxosynthese hergestellten verzweigtkettigen Alkoholen, oder Fettsäuremono- oder -diglyceriden z. B. C12-C18-Kokosfettalkohol, C16-C18-Talgalkohol Ce-C24-Oxoalkohol, C16-C1s-Talgfettsäuremonoglycerid, oder von Addukten von 1 bis 6 Mol Alkylenoxid an die genannten Fettalkohole oder Fettsäureglyceride oder an Fettsäuren, z. B. das Addukt von 2 bis 3 Mol Ethylenoxid an C16-C18-Talgfettalkohol oder von 4 bis 6 Mol Ethylenoxid an ein C16-C24-Fettsäuregemisch oder von 2 Mol Ethylenoxid an ein C12-C18-Fettsäuregemisch. Die Sulfobernsteinsäureester werden in Form ihrer Salze, vorzugsweise Natrium- und/oder Ammoniumsalze, verwendet.The fatty reeds can be saturated or unsaturated, straight or branched. They can be derived from fatty alcohols, branched chain alcohols produced by oxosynthesis, or fatty acid mono- or diglycerides e.g. B. C 12 -C 18 coconut fatty alcohol, C 16 -C 18 tallow alcohol C e -C 24 oxo alcohol, C16-C1s tallow fatty acid monoglyceride, or of adducts of 1 to 6 mol of alkylene oxide with the fatty alcohols or fatty acid glycerides mentioned or with fatty acids, e.g. B. the adduct of 2 to 3 moles of ethylene oxide with C 16 -C 18 tallow fatty alcohol or from 4 to 6 moles of ethylene oxide with a C 16 -C 24 fatty acid mixture or from 2 moles of ethylene oxide with a C 12 -C 18 fatty acid mixture. The sulfosuccinic acid esters are used in the form of their salts, preferably sodium and / or ammonium salts.
Geeignete Emulgatoren (B), die in Kombination mit den Sulfobernsteinsäureestern (A) eingesetzt werden, sind beispielsweise die Addukte von 5 bis 25 Mol Ethylenoxid an Ce-C2o-Fettalkohole oder -Alkylphenole wie C12-C18-Kokosfettalkohol + 8 EO, C16-C18-Talgfettalkohol + 20 EO, Nonylphenol + 9 EO, oder die Sulfate der Addukte von 1 bis 6 Mol Ethylenoxid an Ce-C2o-Fettalkohole, -Fettsäuren oder -Fettsäurealkanolamide, z. B. die Sulfate von C12-C18-Kokosfettsäureethanolamid + 2 EO, C8-C16-Fettsäureethanolamid + 2 EO oder C12-C18-Kokosfettalkohol + 5 EO in Form ihrer Alkali- oder Ammoniumsalze, vorzugsweise Natriumsalze.Suitable emulsifiers (B) which are used in combination with the sulfosuccinic acid esters (A) are, for example, the adducts of 5 to 25 mol of ethylene oxide with Ce-C2o-fatty alcohols or -alkylphenols such as C 12 -C 18 coconut fatty alcohol + 8 EO, C 16 -C 18 tallow fatty alcohol + 20 EO, nonylphenol + 9 EO, or the sulfates of the adducts of 1 to 6 moles of ethylene oxide with Ce-C2o fatty alcohols, fatty acids or fatty acid alkanolamides, e.g. B. the sulfates of C 12 -C 18 coconut fatty acid ethanol amide + 2 EO, C 8 -C 16 fatty acid ethanol amide + 2 EO or C 12 -C 18 coconut fatty alcohol + 5 EO in the form of their alkali metal or ammonium salts, preferably sodium salts.
Die Sulfobernsteinsäureester werden zusammen mit den Emulgatoren den Gerb- oder Nachgerbflotten vor, während oder nach der Gerbstoffzugabe zugesetzt, wobei je nach gewünschtem Ledertyp 0,1 bis 6,0 Gewichtsprozent, vorzugsweise 0,5 bis 4,0 Gewichtsprozent Aktivsubstanz, bezogen auf das Blößen-oder Falzgewicht, eingesetzt werden. Die Flotten zeichnen sich durch gute Beständigkeit aus. Man erhält Leder bzw. Pelzfelle von sehr guter Weichheit. Die Festnarbigkeit ist gegenüber den üblicherweise verwendeten Sulfitierungsprodukten wesentlich verbessert.The sulfosuccinic acid esters, together with the emulsifiers, are added to the tanning or retanning liquors before, during or after the addition of tanning agents, depending on the leather type desired, 0.1 to 6.0 percent by weight, preferably 0.5 to 4.0 percent by weight, of active substance, based on the nakedness -or fold weight, can be used. The fleets are characterized by good durability. Leather or fur skins of very good softness are obtained. The solid grain is significantly improved compared to the commonly used sulfitation products.
