| Résumé : |
Waxes have been a vital part of leather finishing going right back to the ancient Egyptians. All major leather producers have depended on wax as a protective agent, but also as a useful auxiliary. Whether the source of the wax was from animal waxes - such as beeswax, sperm whale fat or from a plant like Carnauba wax, to the modern synthetic waxes, refined out of petroleum products (or synthesised) - they remain vital to leather finishing.
A very natural finish can be applied to the leather, which is just a combination of wax (and oil), which will feed, protect, or provide touch and feel. The wax and oils are lipids, fatty substances and the behaviour of these lipids depends on the structure of the chemical used. |
