Résumé : |
The use of protein-based fillers in the retanning process can play a valuable part in the production of good quality leathers. This type of product is in wide use, but sometimes not applied in the right way. Accordingly, their full benefits are not always achieved or appreciated within the final leather.
Almost all the major chemicals used in the leather tanning processes carry charge so their use involves chemical reactions with collagen. In contrast, protein-based fillers have limited or absolutely no chemical reaction with the protein structure.
These products need using selectively, and not all types or leathers need Hers. For example, heavily vegetable re-tanned leathers, or thin leathers may not require this kind of product. However, where selective filling is needed it is easy to see the benefits that can be gained, and this applies to most leathers. |
