However, leather boots also are worn in slush and rain. There is no longer any need to get cold feet from soggy boots though. High-tech chemicals give leather effective protection against moisture, but are also permeable to air. As a result, the feet can “breathe” without getting sweaty. Levotan W is the name of the silicon polymer applied after tanning that protects the leather against water.
In particular, leather labeled “waterproof” must meet extremely strict requirements: for instance, some shoe manufacturers insist that the leather does not get saturated and only absorbs minimal amounts of water in hours of testing.
Leather, that timeless material, meets different requirements from season to season. As well as clothing and protecting feet, it warms bodies and hands in coats and gloves on frosty days, while also looking chic and elegant. LANXESS is one of the few suppliers in the leather industry to offer all essential products for leather manufacture. Its products range from tanning agents, preservatives, fatliquoring agents, dyes and pigments to tanning and finishing aids.
