摘要： The present invention relates to a novel method of recovering and recycling active tannins from spent vegetable tanning liquors. Using a low molecular weight alcohol as the extraction agent produces an alcohol fraction or precipitate containing extracted active tannins, and leaves virtually all non-tannins in the aqueous phase of the spent tanning liquor. The methods and resulting chemical mixtures of the present invention have a variety of uses and applications. The method can be applied to freshly produced or aged spent vegetable tanning liquors. The methods are further applicable to dried forms of spent tanning liquors through aqueous reconstitution of dried ReTan, followed by alcohol extraction. The recovered chemical mixture contains recovered tannins which can be recycled through combination with fresh tanning liquors to form an improved tanning liquor.

摘要： Verfahren zur Formung eines Oberleders für einen Lederstiefel. Ein schlauchförmiges einstückiges Oberleders wird aus einem Abschnitt eines Beinbereichs einer Bovidenhaut gewonnen. Das Oberleders wird unter Verwendung von Fett und Licker fettgegerbt und unter steigender Konzentration einer Gerbstoffmischung, die etwa 49 Teile eines pflanzlichen Gerbstoffs und etwa 51 Teile eines synthetischen Tannin-Gerbstoffes enthält, nachgegerbt. Die Konzentration der Gerbstoffmischung steigt von 3 zu 6 Grad Beaumé an. Das Oberleder wird mit einer Lickermischung gelickert, die Wasser, einen anionischen Emulgator und einen Licker aufweist, wobei das Wasser eine Temperatur von etwa 45 °C aufweist. Ein Stiefelschaftweiter wird in einen Schaft des Oberleders eingeführt und der Schaft wird mit dem Stiefelschaftweiter um mindestens 100 % aufgeweitet.

摘要： The present invention refers to a process for obtaining a plant extract containing condensed tannins, with astringent characteristics, modified by copolymerization, to be used for tanning and retanning of skins; it also refers to the plant extract thus obtained; and it also refers to the use thereof for treating hides.
The process according to the present invention comprises the following steps:

(a) adding water to a reactor at a ratio between 2.0 and 5.8%, by weight, to the total desired weight of the load;
(b) adding to the reactor an amount between 1.2 and 2.5%, by weight, of a copolymerization agent, selected from acrylic acid, metacrylic acid, mixtures of acrylic acid and metacrylic acid or esters thereof; all the while stirring the mixture;
(c) adding thioglycolic acid at a ratio between 0.1 and 1.7%, by weight, while cooling the mixture, allowing the same to react whereupon there occurs the exothermal reaction and the temperature reaches 95° C, and after the said reaction the product obtained from the reaction being left to cool;
(d) adjusting the pH to values in the range between 3.5 and 7.0, by adding an alkali to the mixture;
(e) mixing a powdered extract of a plant with water at a ratio of about 0.5 to 2.0 kg per liter of water; or
alternatively, mixing a solution of tannin in liquid form in a concentration of 25% to 60%;
(f) raising the temperature of the mixture to a range between 67 and 98° C, to carry out the reaction, for a period of 2 to 7 hours, preferably for 5 hours;
(g) adding the sodium bisulphite at a ratio of 0.5 to 4.0%, by weight, over the amount of tannin;
(h) raising the temperature of the mixture, keeping the reaction system heated at a temperature between 45 and 127° C, the pressure being comprised between 0.2 and 7 kgf/cm 2 ; and
(i) allowing a reaction time of about 4 hours.
