Description
Weichen von Fellen und Häuten Es ist bekannt, Enzyme der Bauchspeicheldrüse in neirtralerL ösung alsM'eichmittel für Felle undHäute, die zti Leder verarbeitet werden sollen, zu verwenden. Bei dieser Behandlung wird die Hautsubstanz eilieblich angegriffen. Das Verfahren hat deshalb bei der Lederherstellung keine praktische Bedeutung erlangt. Des weiteren wurde ein Weichverfahren beschrieben, bei dein wässerige Lösungen von Hefepilzkulturen oder selbstverdauter Hefe verwendet wurden. Derartige Lösungen gehen rasch in Fäulnis über und zeigen nur ungenii;eside Weicheffekte. So wurde deshalb die M'irkung der Hefepilzkulturen durch Zusatz voll Netzmitteln und Aktivatoren, unter anderem auch 1Natriiinibisulfit. zu steigern versucht. Das Verfahren hasich jedoch trotzdem nicht durchsetzen können, vor allein auch deshalb, weil es nicht möglich ist, die Enzyme zu dosieren und den gewünschten Weicheffekt in zuverlässiger Meise zu erzielen. Ferner hat man Pilztryptase zusammen mit Ammoniumsalzen und Bisul9it in schwachsaurer Lösung auf bereits geweichte od-#---r sogar- geäscherte Felle und Häute zur Einwirkung gebracht. um damit einen Enthaarung-s- oder Geizeffekt zu erzielen. Es wurde auch schon vorgeschlagen, in besonderen Fällen Rohfelle unmittelbar in tiiiScbimiiielpilztryptase enthaltendesEnthaarungs-1>ad einzubringen. Diese Arbeitsweise führt jedoch ivcgeri der langen Dauer leicht zu Hautschä(ligungen.Soaking off pelts and hides is known to have pancreatic enzymes in neutral solution as a calibrating agent for hides and skins, which are partly processed by leather should be used. With this treatment, the skin substance becomes indelible attacked. The method is therefore not practical in leather manufacture Gained importance. Furthermore, a softening process was described in the case of the aqueous Solutions of yeast cultures or self-digested yeast have been used. Such Solutions quickly go into putrefaction and show only inadequate soft effects. The effect of the yeast cultures was therefore fully enhanced by the addition of wetting agents and activators, including 1Natriiiniibisulfit. tried to increase. That However, I have not been able to enforce the procedure, mainly because because it is not possible to dose the enzymes and the desired soft effect to achieve in a reliable manner. There is also mushroom tryptase along with ammonium salts and bisulfite in a weakly acidic solution on already soaked od - # --- r even-ashed Hides and skins brought to action. to create a depilatory or stinging effect to achieve. It has also been suggested to use raw hides directly in special cases in tiiiScbimiiielfilztryptase containing depilatory 1> ad to be introduced. This way of working However, if it lasts for a long time, it easily leads to skin damage.
Es wurde nun gefunden, daß die Verwendung 2iiier v-ä sserigen, schwach sauren Lösung von Bakterienproteasen in Anwesenheit vor, Ammoniumsalzen und reduzierenden Verbindungen zum Weichen von Fellen und Häuten eine zuverlässige Kontrolle des Weichvorgangs ermöglicht und zu einem ausgezeichneten Weicheffekt ohne Schädigung der Hautsubstanz führt. Bakterienprotease hat sich gegenüber den Enzymen rler Bauchspeicheldrüse sowie den Pilztryptasen in @li@@@cr Hinsicht überlegen erwiesen. Zur Erzielung bestimmter Effekte können auch andere proteolytische Enzyme mitverwendet werden.It has now been found that the use of 2iiier v-external, weak acidic solution of bacterial proteases in the presence of ammonium salts and reducing Connections for soaking pelts and hides provide reliable control of the soaking process and an excellent soft effect without damaging the skin substance leads. Bacterial protease has opposed the enzymes in the pancreas as well as the mushroom tryptases have been shown to be superior in @li @@@ cr respect. To achieve certain Effects, other proteolytic enzymes can also be used.
Tlei getrockneter Rohware bietet diese -Methode die \löglicbkeit. die MTeiehdauer erheblich abzukürzen. Die flaut wird dal)ei so gründlich durchgeweicht, daß clie :@scliercliemilcalieri gleichmäßig und ohne Er7euung des gefürchtetere Narbenzugs aufgenommen werden. Diese Vorteile hat man nicht nur bei getrockneter Rohware, sondern auch bei der Behandlung von gesalzenen Fellen.This method offers the possibility of partially dried raw material. to shorten the rental period considerably. The doldrums are so thoroughly soaked that clie: @scliercliemilcalieri evenly and without renewing the more feared Scar pull are recorded. These advantages are not only available with dried ones Raw material, but also in the treatment of salted pelts.
Arsainmen finit den angeführten @nz1-ineil kann man auch mit diesen verträgliche \Tetzinittel verwenden. Es besteht aber auch die Möglichkeit, solche Netzmittel vor der Anwendung der Enzyme auf die Felle zur Einwirkung zu bringen. Als \Tetzmittel für die @'orbehandlung kommen z. B. Fettalkoholsulfonate, Fettsäurekondensationsprodukte und All:ylarvlsulfonate in Betracht, ebenso nicht ionogene Produkte. wie Polyglykoläther, oder kationaktive Produkte, wie quarterriäre Ammoniumsalze. Für die gleichzeitige Verwendung zusammen mit dem Enzym kommen vor allem nicht ionogerie Netzmittel. wie Polyglykoläther, od,r aridere damit verträgliche Produkte. wie Ni-substituierte Aminocarbonsäuren, in Frage. Die Kombination mit -Netzmitteln unterstützt die Enzymwirkung und <"-irl:t zudem günstig auf die Emulgierung des Naturfettes. Beispiel 1 Trockene, südafrikanische Rindshäute werden in der Grube mit 9.000%,Wasser, 2% Bakterienprotease, 1'0;0 \Tatriumbisulfit, 1% Amrnoniunichiorid 3 Tage bei pli 5 bis 5,5 geweicht. Beispiel "? Trockene Lammfelle werden mit 10000,'0 Wasser. 1% ßakterienprotease, 0,5% Polyglylcoläther, 0,3% Natriumbisulfit, l'0/0 Ammoniumsulfat bei p;16 geweicht.Arsainmen finite the quoted @ nz1-ineil can also be used with these use compatible \ Tetzinmittel. But there is also the possibility of such Bringing wetting agents to action on the pelts before the enzymes are applied. As a detting agent for the treatment, z. B. fatty alcohol sulfonates, fatty acid condensation products and All: ylarvlsulfonate into consideration, as well as non-ionic products. like polyglycol ether, or cation-active products, such as quarterly ammonium salts. For the simultaneous Mainly non-ionic wetting agents are used together with the enzyme. how Polyglycol ether, or other compatible products. like Ni-substituted Aminocarboxylic acids. The combination with wetting agents supports the enzyme action and <"- irl: t also has a beneficial effect on the emulsification of natural fat. Example 1 Dry, South African cowhides are in the pit with 9,000%, water, 2% bacterial protease, 1'0; 0 \ Tatrium bisulfit, 1% ammonium dichloride soaked for 3 days at pli 5 to 5.5. Example "? Dry lambskins are treated with 10000, '0 water. 1% bacterial protease, 0.5% polyglyl col ether, 0.3% sodium bisulfite, l'0 / 0 ammonium sulfate at p; 16 soaked.
