About the product

Leather is a natural product and considered a by-product of the food industry that produces meat for human consumption.

It qualifies by different types, depending on the animal, and treatment of this leather.

All animals have different skin types, which varies according to their breed, age, sex, climate, nutrition and well-being provided by the breeder, and each of them has different fiber structures.

Leather raw material quality

Processes and methodologies used to slaughter animals, such as situations that instill greater or lesser stress on them,different skinning methodologies and the subsequent raw materials conservation processes,will determine the level quality for the final product.

Thus, these factors must be taken into account when selecting the leather raw material to be used for the different articles to be produced.

Leather division

The entire Cow hide can be separated by:

Division by area

Shoulder
~ 25%

Butt
~ 50%

Belly
~ 20-30%

Division by Thickness

The transformation process can take place with both parties:

• Integrated

Integral skin / Hide

• Splitted

Splitted skin / Hide - one product
The split - other product

Grain side

Flesh side

The Tanning

Is the most important step in production, and regardless of its quality, it is what defines the final Biodegradability of the skin.

Vegetable Tanning

Process performed with vegetable substances, such as the bark of some trees.

This process has been around for over 5,000 years and has been, for many centuries, the main method of tanning.

The tannin content, which exists in the bark of these trees, is the substance that linked to collagen, allows the isolation of natural fibers against fungi and bacteria that are responsible for the skin degradation.

Chromium Tanning

This tanning uses mineral tannins (chromium salts) and since it was discovered in 1858, has become the most common way of tanning a leather, especially because it is a much faster process than vegetable tanning.

The leathers resulting from this tanning and at this stage, are usually called Wet-Blue.

Wet-White Tanning

It is a synthetic tanning, which uses synthetic agents produced artificially, so they have no counterpart in nature. Examples of these are formaldehyde, glutaraldehyde, phenols and acrylates. This tanning method is not employed as an isolated process, but mainly as part of a tannery process combined with chromium or vegetable.
