Résumé : |
Fatty spew is attributed to the secretion of solid fatty compounds from leather. It can be caused by the natural fat present in the leather or by fatty compounds that have been incorporated into the leather during the oiling process. So it is better to use special synthetic oil that has a minimal tendency to form fatty spew or to use ails of a high iodine value. This means that there would be less chance of spew in the case of application of fat liquor, and one should also try to tackle the problems before processing wet-blue by using a strong emulsifying agent to avoid spew formation due to natural fat. On the other hand, it will also be beneficial because a variety of problems are caused by insufficient removal of natural grease such as bad odeur, poor preservation and a lack of inner softness. High amounts of natural fat due to poor degreasing or the presence of fat liquors with high amount of naturel oils (unsaturated fats) have a negative affect and can form significant levels of chromium VI. synthetic fats are favourable. |
