| Résumé : |
The paper "New perspective on wet processing" was published in World Leather October/November 1993, in which the advantages offered by the removal of phospholipids were discussed. It is a curious fast that the advantages offered by a new development are sometimes so restricted by established practices that the technology becomes marginalised. In the situation described, the gains in surface area became problematic in machine operation, the removal of unwanted hide components created increased effluent charges, and improvecl wet blue properties increased chemical costs. At that Lime the advantages were judged against the disadvantages and found to be lacking. Given that the value of rom/ hides and leather seing prices - strongly influenced by area and quality - are so important to the tanner, perhaps it is rime to re-evaluate this technology. |
