by Haryana Leather Chemical Leather Chemical Manufacturers

The process involved in making leather is a complicated process and consumes time. However, leather can be made of any type of skin or hide, though some skins are better for one purpose than others. The leather received at our end does not come as it is, but it has to go through a process known as Tanning leather process.

Reason Behind Leather Tanning

Leather tanning is largely been practiced by the leather finishing chemicals manufacturers to change the structure of proteins available in the hide or skin. Tanning curbs the decaying process and transforms the skin into leather, which further can be used in making different products.

Leather is tanned in two ways:

§ Chrome tanning

§ Vegetable tanning

Chrome Tanning

Chrome tanning is a more recent method of tanning, but the most dominant one as well. It consists of steps, wherein the hides are soaked in baths filled with acidic salts and then are taken further for chrome tanning. Here, the bath has chromium tanning agents and further the bath acidity is decreased until the surface of the hides starts absorbing the chromium agents.

Benefits of Chrome Tanning

ü Chrome tanning is faster than vegetable tanning;

ü This technique can be altered in a variety of ways;

ü Produced leather is water-resistant;

ü Leather can be dyed in different colors;

ü The outcome from chrome tanning produces leather which absorbs heat better;

ü It consumes a day or two to complete the process.

Vegetable Tanning

Vegetable tanning has been popular since ancient times and involves the tanning from the bark and leaves of trees and plants. In this process, the hides are placed in the tanning pit, containing tanning solutions of various strengths. After the period of two to three months, the tanners shift the hides from drum to drum, here the tanning agents penetrate the skins and the fermentation and depositions process, finally leaves the hides with a distinct color and appearance. The final product contains a distinctively sweet, woody fragrance with leather.

Benefits of vegetable tanning

ü This method uses natural materials and products;

ü The final leather is usually quite thick;

ü This type of leather can mold, stretch and breathe;

ü It retains every bit of intricate detail made on it.
