Chaulage
ConfitageLe confitage est une action biochimique effectuée au moyen de produits enzymatiques, qui a pour but de dégrader les fibres élastiques, contribuant ainsi à augmenter la souplesse du cuir. En outre, les enzymes complètent la dégradation des résidus épidermiques, donnant ainsi une fleur plus propre et plus lisse.

| Résumé : |
During the 1980s, the consumption of leathers by the clothing sector grew annually by around 5% rising to approximately 2 billion square feet a year, representing 10-15% of the total area of leather produced.
The market for these garment leathers is wide, ranging from low value articles that may be compared to cheap textile garments to high quality products with all the characteristics of presting items. These leathers are strongly represented in the fields of sports-wear and teen-clothes, where leathers are made from many types of raw materials requiring different approaches to process. Generally, garment leathers are associated with sheep, goat and bovine as raw stock, but the amount of pigskins used should not be neglected.
The quantity of this raw material used in leather production is limited as not all slaughtered pigs are flayed, the skin often being retained with themeat, or used in the production of gelatin.
Quality can also suffer according to the conditions in which the animal has been kept, and the conditions of slaughter strongly influence the hide characteristics. This tends to concentrate the production of leathers onto the flesh side for suedes and the manufacture of grain leathers, such as nappas or clasic nubuk is rather limited.
Another peculiarity found in pigskins is the difference in structure and fibre length between the backside and neck areas, and was for a long period an obstacle to the success of pigskins in the garment field. |
