Treatment And Processing Of Natural Fur Or Leather
(AREA)
Abstract
Improvements in the leather greasing process, particularly applicable to white and fine leathers, characterized in that the leather is treated with 2 "10% based on the leather weight, of a fatty acid derivative containing epoxide groups, obtained by epoxidized of unsaturated fatty acid or wax derivatives in which the double bonds are completely or partially converted into epoxide groups by treatment with peroxides, because the leather thus treated is dried at a temperature of 10 to 60 [deg.] c. And because it is heated at a temperature sufficient to produce the resination or molecular augmentation of the epoxidized derivative. (Machine-translation by Google Translate, not legally binding)
