Description
Weichen von Häuten und Fellen Es ist bekannt, daß das Weichen von Häuten und Fellen durch verschiedene Zusätze zum Weichwasser gefördert werden kann. Es sind z. B. Weichbrühen beschrieben, die Natronlauge, Natriumsulfid, Natriumsulfhydrat oder Natriumsülfit enthalten. Diese Mittel bewirken auf Grund ihrer Alkalität unerwünschte Schwellungserscheinungen und lassen den Weichvorgang in einem pH-Gebiet vor sieh gehen, in welchem das Bakterienwachstum gesteigert ist. Es ist weiterhin bekannt, die Weiche durch Zugabe von Mercaptocarbonsäuren oder deren Salzen zur Weichbrühe zu beschleunigen. Die Nachbeile in der Verwendung dieser Verbindungen liegen darin, daß bei scharf getrockneten Häuten und Fellen eine hinreichende Auflockerung, d. h. Aufhebung der Faserverklebung in verhältnismäßig kurzer Zeit nicht erreicht wird. Man erhält wenig volle Leder mit härtlichem Griff und rauhem Narben.Soaking of hides and skins It is known that soaking of Hides and skins can be promoted through various additives to the soft water. There are z. B. soft broths described, the sodium hydroxide solution, sodium sulfide, sodium sulfhydrate or sodium sulphate. Due to their alkalinity, these agents cause undesirable effects Signs of swelling and allow the softening process to take place in a pH range go, in which the bacterial growth is increased. It is also known the soft by adding mercaptocarboxylic acids or their salts to the soft stock to accelerate. The disadvantages of using these compounds are that with sharply dried hides and skins a sufficient loosening, d. H. Removal of the fiber bonding is not achieved in a relatively short time. Little full leather with a hard feel and rough grain is obtained.
Es wurde nun gefunden, daß man die oben geschilderten Schwierigkeiten beheben kann, wenn man das Weichen von schwer aufweichbaren, starken Häuten mit niedrigmolekularen Mercaptoalkansulfonsäuren bzw. deren Salzen durchführt.It has now been found that one can overcome the difficulties outlined above can be remedied by soaking tough, tough skins with low molecular weight mercaptoalkanesulfonic acids or their salts.
Als Mercaptoalkansulfonsäuren kommen in Betracht die 2-Mercaptoäthansulfonsäure, 1,3-Mercaptopropansulfonsäure, 1,3 - Mercaptobutansulfonsäure, 1,4 - Mercaptobutansulfonsäure. Vorteilhafterweise wendet man diese Sulfonsäuren in Form ihrer wasserlöslichen Salze an. Besonders geeignet sind sie in Form ihrer Alkali- oder Ammoniumsalze oder in Form der Salze von organischen Basen, wie Salze des Dimethylamins, Triäthanolamins, Diäthanolamins.Suitable mercaptoalkanesulfonic acids are 2-mercaptoethanesulfonic acid, 1,3-mercaptopropanesulfonic acid, 1,3-mercaptobutanesulfonic acid, 1,4-mercaptobutanesulfonic acid. These sulfonic acids are advantageously used in the form of their water-soluble salts at. They are particularly suitable in the form of their alkali or ammonium salts or in Form of salts of organic bases, such as salts of dimethylamine, triethanolamine, Diethanolamine.
Weiterhin wird der Weichvorgang dadurch günstig beeinflußt, daß man die erfindungsgemäßen Mercaptoalkansulfonsäuren in Verbindung mit anionaktiven oder nichtionogenen Netzmitteln anwendet.Furthermore, the softening process is favorably influenced by the fact that the mercaptoalkanesulfonic acids according to the invention in conjunction with anion-active or uses non-ionic wetting agents.
Der Zusatz der erfindungsgemäßen Mercaptoalkansulfonsäu@ren oder von deren Salzen zum Weichwasser erfolgt in Mengen von 0,05 bis 1 g/1. Der Netzmittelzusaitz beträgt 0,5 bis 1 g/1.The addition of the mercaptoalkanesulfonic acids according to the invention or of their salts to the soft water take place in amounts of 0.05 to 1 g / l. The wetting agent additive is 0.5 to 1 g / l.
Abgesehen von den bereits eingangs genannten Vorteilen haben die Mercaptoalkansulfonsäuren gegenüber den bekannten Mercaptocarbonsäuren den weiteren Vorteil, daß sie in viel geringeren Konzentrationen wirksam sind. Trotzdem ist die Weichgeschwindigkeit durch das leichte Eindringen der erfindungsgemäßen Sulfonsäuren bzw. deren Salze noch größer als die der Mercaptocarbonsäuren.Apart from the advantages already mentioned above, the mercaptoalkanesulfonic acids have compared to the known mercaptocarboxylic acids the further advantage that they are in a lot lower concentrations are effective. Even so, the soft speed is through the easy penetration of the sulfonic acids according to the invention or their salts greater than that of the mercaptocarboxylic acids.
Beispiele 1. Getrocknete Ziegenfelle werden mit einer Lösung von 0,1 g/1 des Triäthanolaminsalzes der 1,4-Mercaptobutansulfonsäure im Faß geweicht. Nach 3 Tagen ist eine einwandfreie Weiche erreicht. Als Wasseraufnahme ergab sich 124'%. Bei Zusatz von 0,5 g Natriumthioglykolat betrug die Wasseraufnahme dagegen nach 3 Tagen nur 107%.Examples 1. Dried goat skins are with a solution of 0.1 g / 1 of the triethanolamine salt of 1,4-mercaptobutanesulfonic acid soaked in the barrel. To A perfect turnout is reached within 3 days. The water uptake was 124%. On the other hand, when 0.5 g of sodium thioglycolate was added, the water uptake was lower 3 days only 107%.
2. Sonnengetrocknete Büffelhaut wird geweicht mit 0,5 g/1 des 1,3-mercaptopropansulfonsaurem Dimethylamins und 0,2g/1 eines handelsüblichen Netzmittels z. B. Alkylsulfonat oder Alkylbenzolsulfonat. Nach vollendeter Weiche (etwa 2 Tage) erhält man eine besonders gut aufgelockerte, gleichmäßig durchgeweichte Rohhaut.2. Sun-dried buffalo skin is soaked with 0.5 g / l of 1,3-mercaptopropane sulfonic acid Dimethylamine and 0.2g / 1 of a commercial wetting agent z. B. alkyl sulfonate or Alkyl benzene sulfonate. When the soak is complete (about 2 days) you get a special one well-loosened, evenly soaked rawhide.
