| Résumé : |
This study evaluates the combination of a lipase and a mild protease enzyme to clean the surface of chrome tanned stock of grease, dirt, scud, and other stains, for the purpose of making more uniformly colored leather. A significant reduction was found in grease stains, neck wrinkle discoloration, and other stains. Also , an improvement was observed in the brightness and uniformity of dyeing - backbone to belly and side to side within a mill. This was accomplished using extremely low amounts of a combination of two enzymes selected to be particularly active in the conditions of retanning with respect to pH, temperature, running times, and presence of other chemicals. |
