Controlling colour is an essential component of the vegetable leather-tanning process, and often a reason why tanneries are hesitant to experiment with natural tanning methods. The perception is that tanning leather with organic alternatives to chromium has major limitations, producing just a single shade of brown.
Thanks to years of research and development undertaken by NTE, there has never been a greater range of choices in shades, grades or finishes of leather that can be achieved through natural tanning methods.
All of NTE Mimosa’s tanning agents are based on the same basic ingredient: tannin extracted from the bark of the acacia mearnsii, commonly known as the black wattle. Untreated, this mimosa extract delivers a rich and lustrous leather with a red brown-hue, and a fullness that is ideal for sole, strap and case. When treated, however, a range of colours is possible.
