Vegetable Tanning

Vegetable tanning is a natural and artisan process that is used to transform raw leather into a more resistant material with a natural and fine appearance. His method is a bit slow but environmentally friendly. It is carried out in piles and later complemented in wooden drums using natural tannins available in powder or liquids from wood, pods, fruits or leaves.

 

Our vegetalized leathers for sole, midsole and saddle are pile tanned with natural products, giving greater resistance and better benefits for artisanal and industrial work, such as engraving, molding, burning and stamping, among others.

 

Advantages:

 

  • Large caliber leathers.

  • Environmentally friendly process.

  • Greater resistance and consistency due to pile tanning.

  • Greater resistance to water, since the fiber of the leather remains more closed.

  • It has greater benefits for artisan and industrial work, such as engraving, molding, burning and stamping.

  • Because we tan North American leather we offer greater thickness and extension in the various presentations.

  • Greater resistance to the passage of time.

Chrome and / or Chrome free tanning (Wet-white)

Chrome tanning is a method that uses chemical solutions, acids and salts (including chromium sulfate) that interact with collagen fibers to obtain a stronger and more durable leather (Wet Blue).

Advantage:

  • We use the latest and most advanced finishing techniques achieving the following results:

  1. Greater softness and a more natural texture.

  2. Easier sewing.

  3. Retention to uniform engraving.

  4. Greater physical properties.

  • Leathers with exceptional softness.

  • Leathers with outstanding dyeability; bright, clean and uniform colors.

  • Greater extension.

Raw Hides
 

The raw hides are extracted from the leather splitting process.

 

On the one hand, you have the whole flower that can be processed in various types of tanning and the lower part that is the meat that is bleached and specially treated to make teethers for pets.

Mixed tannning
(Chrome tanned with vegetable retanning)

Mixed Tanning uses a combination of synthetic tannins, vegetable tannins, hydrochloric acid and minerals, such as aluminum and zirconium salts. Wet-white tanning allows the manufacture of chrome-free leathers using the equipment used for this method.

Advantage:

  • Strong but malleable.

  • Resistant leather without loss of malleability and softness.

  • Mixed tanning is soft and pleasant to the touch.

  • Leathers with better performance.
