TECHNICAL ASPECTS


For car interiors leather must follow very strict specifications. One of the critical issues is tear resistance which can be negatively affected by problems present before retanning. Some examples are bad conservation, dehydration of the hide that leads to the non-sliding of the fibers or mechanical operations conducted incorrectly that stress the dermis. It is essential to lubricate the fibers with the right combination of fatliquors, which give the firmness required together with an adequate mechanical strength.

Very little fogging is now a well integrated requirement for those who produce automotive leathers but is always an aspect to keep under control.

On the other hand, inside the tannery, the quality of the residual baths and the consequent impact on the water purification process which can have high COD values, especially in the case of wet-white, is also taken into account.



LUB V-48


LUB V-48 is a soft and very firm fatliquor used in a prevalent quantity in the mixture of fatliquors for automotive leathers. It closes the grain visibly and relaxes the skin. It also has very low COD, if used in an appropriate recipe, and has very low fogging.

LUB VPG-8


LUB VPG-8 is a lubricating polymer that improves the tightness of fibers and keeps them from tearing. A small amount is used and is particularly effective if inserted into the end of the process. It has no negative effects on fogging.
