(FR) PROCEDE D'EPILAGE DE CUIRS ET DE PEAUX AU MOYEN D'ENZYMES
Abstract
(EN)
The invention relates to an environmentally friendly method for dehairing of hides or skins by means of enzymes comprising the following steps: 1) the hides or skins are soaked, 2) the soaked hides or skins are subjected to a main soak, and 3) the thus treated hides or skins are dehaired by addition of water, exposure to mechanical influence and subjection to at least one protease, characterized in that the hides or skins are subjected to at least one protein disulfide redox agent at least one time during step 1) to 3).
(FR)
L'invention concerne un procédé d'épilage de cuirs ou de peaux ne nuisant pas à l'environnement, au moyen d'enzymes. Ledit procédé consiste 1) à tremper les cuirs ou peaux, 2) à les soumettre à un trempage principal, et 3) à épiler les peaux ou cuirs ainsi traités, par addition d'eau, exposition à une force mécanique et à au moins une protéase, les peaux et cuirs étant exposés à au moins un agent d'oxydo-réduction protéique au bisulfure, au moins une fois dans les étapes 1) à 3).
