Definition, history and origins of nappa leather
Nappa leather refers to lamb, goat or veal skin. It is a very thin, smooth and worked leather. It is the result of transformations into tannery. A surface treatment is added to its traditional treatment to protect the skin as much as possible. It is distinguished by its supple, grain-free appearance and its resistance to the sun and bad weather.
For the more curious, here are the steps of transforming leather skins:
- First of all, salt the skins and keep them at a temperature of about 10oC in order to preserve them. At this stage, they can lose up to 10% of their weight in water.
- 15 days later, the skins are sorted according to their quality (thickness, defects, weight, size ....).
- They are then sent to tannery. This is where the "river work" begins, which consists of 5 operations: soaking (to get rid of the last impurities), waxing (to remove hair), peeling (removal of subcutaneous tissue), confiting (softening of the leather), pickling (acidification of the skin). The skin is then tanned (transformation of the skin into leather thanks to tannins).
- The leather then undergoes a corroyage (chemical and mechanical treatment that give it its color, its flexibility .... ).
- It is then wrung out one last time, and put in the wind in order to be stretched and dried.
- Finally, the final step is called finishing. This is where leather takes its visual characteristics (its grain, its appearance, waterproofness ...).
After the technical part, let's talk a little bit about history now. Leather work is an ancestral activity. It originates in prehistory, when man wants to protect himself from the elements and begins to design clothes or huts. The Indians also use it to cover their teepees. However, the precise date of the beginnings of tanning is not known. In the Middle Ages, leather shops were all located near a river. The same is true for the first artisanal tanneries before the development of the chemical industry in the 19th century. This industry is becoming more and more important and new techniques are emerging. An activity in perpetual motion, advances range from the direction of protecting the environment and reducing its impact.
