Abstract
Äschern von vorgeweichten Häuten unter Zusatz von Schwefelsäureestern ungesättigter oder gesättigter Fettalkohole mit 6 bis 12 Kohlenstoffatomen.Liming of pre-soaked hides with the addition of sulfuric acid esters of unsaturated or saturated fatty alcohols with 6 to 12 carbon atoms.
Description
Verfahren zur Herstellung von gerbfertigen Hautblößen Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung gerbfetrtiger Hautblößen unter Gehinnung der Haare. Durch das neue Verfahren wird eine vorzügliche Durchäschertmg der Haut bei gleichzeitiger Gewinnung der Haare in unbeschädigtem, für die Verarbeitung in der Textilindustrie geeignetem Zustand .erzielt.Process for the production of ready-to-tan hide pelts The present invention is a process for the preparation of tannin skin pelts with coagulation of the hair. The new process ensures excellent cremation the skin while obtaining the hair in undamaged, for processing suitable condition in the textile industry.
Die Arbeitsweise besteht darin, daß man, wie üblich, geweichte Rohhäute und Felle in einem schwachen, gegebenenfalls Sulfidionen enthaltenden Äscher unter Zusatz von Schwefelsäureestern ungesättigter Fettalkohole oder Schw.efelsäur,estern gesättigter- Fettalkohole mit 6 bis 12 Kohlenstoffatomen behandelt. Beispiel i Süddeutsche gesalzene Kalbfelle Vorweiche: Einige Stunden in gewöhnlichem Wasser.The way of working consists in the fact that, as usual, raw hides are softened and hides in a weak liming, optionally containing sulphide ions Addition of sulfuric acid esters of unsaturated fatty alcohols or sulfuric acid esters saturated fatty alcohols with 6 to 12 carbon atoms. Example i South German Salted calfskins soaking: a few hours in ordinary water.
Hauptweiche: 5oo bis 8oo% Wasser, 6o g Natriumsalz des Ricinolschwefelsäur.ebutylesters je Kubikmeter, Sog Methylcyclöhexanol je Kubikmeter. Äscher: 60'o gebrannter Kalk vom Weichgewicht der Felle, o,5 bis o,750'0 Schwefelnatrium kond. vom Weichgewicht der Felle, 759 Fettalkdholsulfonat je Kubikmeter. Dauer: 2 Tage.Main switch: 500 to 8oo% water, 60 g sodium salt of ricinoleic acid butyl ester per cubic meter, suction methylcyclohexanol per cubic meter. Liming: 60'o quick lime of the soft weight of the skins, 0.5 to 750'0 sulphurous sodium cond. of the soft weight of the skins, 759 fatty alcohol sulfonate per cubic meter. Duration: 2 days.
Temperatur: i8 bis 2o'. Beispiel 2 Rindshäute (oder Kalbfelle) für Fahlleder Vorweiche: i Tag in gewöhnlichem Wasser. Hauptweiche: 5oo bis 8ooo'o Wasser.Temperature: i8 to 2o '. Example 2 cowhides (or calfskins) for Pale leather pre-soak: 1 day in ordinary water. Main switch: 5oo to 8ooo'o water.
3oo bis 400 9 Ätznatron je Kubikmeter, i 2o g Natriumsalz des RicinoIschwefelsäurebutylesters je Kubikmeter, 6o,- Methylcyclähexanol je Kubikmeter.300 to 400 9 caustic soda per cubic meter, 12o g of the sodium salt of butyl ricinosulfate per cubic meter, 6o, - methylcyclahexanol per cubic meter.
Dauer: 2 Tage. Temperatur: 18 bis 2o".Duration: 2 days. Temperature: 18 to 2o ".
Weißkalkäscher: 8% gebrannter Kalk vom Weichgewicht der Häute bzw. Felle. igog Fettalkoholsulfonat je Kubikmeter.White lime incinerator: 8% quicklime of the soft weight of the hides or Skins. igog fatty alcohol sulfonate per cubic meter.
Dauer: 5 bis 6 Tage (bzw. 3 bis q. Tage bei Kalbfellen).Duration: 5 to 6 days (or 3 to q days for calfskins).
Temperatur:. 18 bis 2o`.Temperature:. 18 to 2o`.
