Abstract

Afin d'obtenir un procédé de préparation de peaux ou de fourrures animales moins laborieux et plus respectant mieux l'environnement, on traite les peaux ou les fourrures animales après une trempe classique dans une solution classique de tannage dans laquelle du dioxyde de carbone est dissous sous pression. On peut ainsi réduire considérablement le temps habituellement nécessaire pour obtenir des cuirs ou des fourrures, étant donné que leur durée de traitement est sensiblement réduite. On peut en outre de cette façon réunir plusieurs étapes classiques de traitement en une seule étape de traitement. Au lieu des 20 à 40 tonnes d'eaux usées habituellement produites par tonne de cuir ou de peaux dans les procédés classiques, seulement 2 tonnes environ d'eaux usées sont produites par tonne de cuir ou de peaux. Ce procédé a non seulement un impact sensiblement réduit sur l'environnement, par rapport aux procédés classiques, mais il est aussi beaucoup plus économique, compte tenu de la réduction considérable de la durée totale de traitement.
