This process is done on the material to enhance the natural beauty of the leather and provide the final polishing touch. The main processes involved here are:
· Adjustment of gloss level
· Other specific process based on client requirement
This phase is carried out by placing the hides into drums, inside high-temperature water enriched with dyes dissolved in water. This is done so that the dye can be absorbed not only on the surface of the leather but throughout the thickness of the skin, giving uniformity to the color.
Finally, a layer of a binder pigment mixture is applied to the surface of the smooth leather that has already been completely pre coloured, with aniline dyes this colour coat is also called finish or pigmentation. Motorcycle suits, leisure jackets, shoes, cars, furniture, and bags made of smooth leather have this protective colour layer. These leathers are then referred to as pigmented Leathers or finished Leathers.
The first step here is the production of wet blue an intermediate product in leather processing that must remain moist throughout its life cycle. The hide is processed using chromium tanning process that gives it the beautiful blue color. This process imparts the smooth to leather that we all love. Splitting and shaving is done to obtain the leather of the desired thickness. We ensure that the cooling water used in this process is processed and reused to ensure the sustainability goals of the company. Wet Blue skins are re-processed inside special drums. This part of the process gives the leather more mechanical resistance and uniformity, but also softness, elasticity and lightness. In practice, re-tanning is essential in determining the high quality of the skin and some of its final characteristics
The crust formation is the next stage where the blue wet hide is redyed and dried to obtain a leather of the desired color and texture.
