– Tannage of hides –
。Vegetable Tan
This type of tannage is without doubt one of the oldest: used since the Egyptian and Roman eras as the main footwear production technique and, still today, is one of the preferred techniques by those seeking environment-friendly, hypoallergenic products. Using quick tannage in drums, the leather becomes soft and is especially sought after in the clothing industry. The end products acquire a 100% natural cut and a vintage effect that offers the entire product a strong sense of traditional workmanship.
The so-called “vegetable” is the material comes from the tree, which we call “tannin”. It is brown-yellow colour, very astringent. After extraction into a tannin powder can be use for making leather, the very ancient and traditional tanning method. When we taste the red wine, something we feel it has “strong tannin”, actually they are the same materials.
This processing is particularly recommended for end products such as saddlery, bridlery, belts, bags and leather goods. Not to be forgotten, due to its hypoallergenic properties, is its immense use in the manufacture of linings, i.e. product parts that come into contact with the skin (for example, shoe insoles or watch straps)

。Chrome Tan
This type of tanning is the most widespread in the world and is used for most leather products on the market. The first chrome tanning originated recently, at the beginning of the 20th century, quickly becoming the most widely used process. The main advantage of using chrome-tanned material is that they can be applied for different types of products: it is simple to dye, water-resistant, elastic and can easily be used to make items of clothing. The tanning process takes from 3 to a maximum of 24 hours, which is less time compared to the vegetable tanning technique. At the end of the tanning stages, the leather becomes a greenish blue colour, which can vary in shade. The term used is wet-blue owing to this particular colour.
This process is particularly suited to end products such as: clothing, footwear, all types of leather goods, bags and furnishing.

。White Leather
The Nuti White Leather (metal free) technique is extremely innovative and the Nuti Ivo group is one of the first groups in the world to offer it on the market. The final product is a type of leather similar in all aspects to the leather obtained with chrome tanning. However, it provides increased strength and resistance to pull and tear (we have performed lab tests acknowledged at international level). Thanks to the total lack of heavy metals used during the procedure, the environmental impact is reduced, resulting in a non-allergenic and natural product just like those created using vegetable tanning. The leathers made using this innovative tanning procedure will be available soon, in line with our increasingly ecological, environmentally-friendly products.
This process is particularly suited to end products such as: clothing, footwear, all types of leather goods, bags and furnishing.
