Verfahren zur Herstellung von lederähnlichen Produkten.
Die Erfindung betrifft ein Verfahren zur Herstellung lederähnlicher Produkte, welches darin besteht, dass die Häute von Fischen (insbesondere von Haifischen) und Walfischen den in der Gerberei üblichen Behandlungsweisen (Beizen, Spülen, Gerben usw.) unterworfen werden.
Eine besondere Ausführungsart des Verfahrens ist beispielsweise folgende :
Die Häute worden gesalzen und gespült, auf Rahmen gespannt, getrocknet, von den Stacheln befreit, dann in lauwarmem Wasser geweicht und gebrochen und in eine Lösung von 200 l Wasser und 1 kg Arsenik oder Schwefelnatrium oder je 1/. kg beider Stoffe gelegt, in der sie zirka drei Tage verbleiben.
Sodann werden die Häute in wässerige Kalkmilch gebracht, in der sie ebenfalls zirka drei Tage verbleiben, kommen sodann in eine Lösung von 1 1 Salzsäure auf 50 l Wasser, werden in derselben zirka fünf Minuten lang umgerührt und dann in einer Walke mit 100 Wasser, 25 bis 30 l Hühnerkot und 1/2 leg einer beliebigen chemischen Beize (auf zirka 180C erwärmt) gebeizt. Nach dem Beizen werden die Häute zuerst in reinem lauwarmen Wasser und dann in einer Lösung von 11 Salzsäure auf 200 l Wasser gespült.
Darauf werden die Häute in einen Bottich mit Brühe von zirka 5 bis 6"gebracht, der ein geeigneter Gerbstoff an jedem dritten Tage zugesetzt wird, bis die Häute fertig gegerbt sind.
Die Behandlung der Fischhäute ist nicht unbedingt an die vorbeschnebene gebunden ; je nach den gewünschten Eigenschaften des zu erzielenden Lederersatzes können auch andere in der Gerbtechnik übliche Massnahmen in Anwendung kommen.

Process for the production of leather-like products.
The invention relates to a method for the production of leather-like products, which consists in subjecting the skins of fish (especially sharks) and whales to the methods of treatment (pickling, rinsing, tanning, etc.) customary in tannery.
A special embodiment of the method is, for example, the following:
The skins were salted and rinsed, stretched on frames, dried, freed from the spines, then soaked in lukewarm water and broken and placed in a solution of 200 l of water and 1 kg of arsenic or sodium sulphide or 1 / each. kg of both substances, in which they remain for about three days.
The skins are then placed in watery milk of lime, in which they also remain for about three days, are then placed in a solution of 1 liter of hydrochloric acid to 50 liters of water, are stirred for about five minutes and then in a fulling machine with 100 water, 25 up to 30 l chicken droppings and 1/2 layer of any chemical stain (heated to approx. 180C) pickled. After pickling, the hides are first rinsed in pure lukewarm water and then in a solution of 11% hydrochloric acid in 200 liters of water.
The hides are then placed in a vat of about 5 to 6 "broth to which a suitable tanning agent is added every third day until the hides are completely tanned.
The treatment of fish skins is not necessarily tied to the pre-snow level; Depending on the desired properties of the leather substitute to be achieved, other measures customary in tanning technology can also be used.
