Leather tanning with black wattle tannin is an excellent option among tanning methods, as it benefits hides in several ways.
Among these benefits are increased strength and durability, as well as the development of unique characteristics in terms of color and texture.
But how does this substance work? Vegetable tannin acts by precipitating the proteins in the hide, which occurs due to its ability to bind to macromolecules.
This reaction creates a stable structure that protects the hide against decomposition, positively impacting durability and generating several other benefits valued by both the industry and the final consumer.
Follow along and discover the main benefits of choosing leather tanning with black wattle tannin.
Benefits of Leather Tanning with Black Wattle Tannin
When leather is tanned using black wattle tannin, the result is a hide with a much more natural appearance compared to other methods.
In addition to its natural look, check out other benefits of this tanning process:
1. Sustainability
Vegetable tannin is a natural and biodegradable substance extracted from the bark of trees and plants such as black wattle. As a result, its use in leather tanning is free from heavy metals such as chromium, avoiding residues that cause environmental pollution and require greater investment in waste treatment.
In other words, besides offering significant environmental advantages, the use of tannins helps reduce costs associated with the treatment of liquid effluents generated by the tanning process.
2. Protection Against Fungi and Bacteria
In plants, one of the main functions of tannins is defense against predators and pests. This protective function extends to leather when tannins are used in tanning, creating a natural barrier against the proliferation of bacteria and fungi in leather products.
3. Different Shades
Seta works with different lines of vegetable tannins in a variety of shades, allowing you to produce leather ranging from lighter to darker tones, expanding its application possibilities.
4. Ease of Use
In the tanning process, the addition of Seta’s black wattle tannin is easy, as the substance has good water solubility and penetrates quickly.
In addition, vegetable tannin can be combined with synthetic tannins and other vegetable extracts, resulting in better distribution of retanning agents, fatliquors, and dyes.
5. Versatility
Black wattle tannin is highly versatile and can be used in all vegetable tanning systems, whether static in pits or fast in drums. It is capable of producing soft leathers, such as metal-free leathers, as well as heavy leathers, such as soles and insoles for footwear applications.
It is also versatile enough to be used in the retanning of chrome-tanned leather of any softness and thickness.
6. Unique Qualities
Tannins impart distinctive qualities to leather by improving texture and ensuring better filling, as well as facilitating burnishing and grain firmness. They also provide excellent print retention and sanding properties.
7. Increased Strength
When black wattle vegetable tannin is used in retanning, it increases the strength of the hide, which is especially important for leathers that must withstand stretching stresses.
In addition, tear strength is also enhanced during retanning, including in different directions.
