Advanced processes aligned with environmental responsibility
From Raw Hide to Finished Leather
The hide transformation process is ancient, yet in recent years it has reached a high level of technological development, enabling more efficient and faster processes with lower environmental impact.
CV Couros masters every step of this cycle, from raw hide intake to the finished product ready for the footwear and apparel industries.
The Transformation Cycle
1. Beamhouse (Ribeira)
Hides are hydrated, dehaired and fleshed, making them ready for the second phase. This fundamental step prepares the hide to absorb the chemicals used in tanning.
2. Tanning — Wet Blue
The leather is chemically modified to gain durability. Called Wet Blue due to the moist appearance and blue hue from the chromium salts used. Hides are then graded and measured, ready for sale or stock.
3. Retanning & Dyeing
Wet Blue hides undergo a further chemical process to acquire specific characteristics matching their end use — footwear, apparel or leather goods. Color, feel and finish are defined at this stage.
4. Mechanical Processes & Finishing
Successive mechanical operations until final characteristics are achieved. Products can be grain-side (napa, velvet, lining) or flesh-side (suede, chamois) with a wide range of fashion-forward colors.
