Résumé : |
A method for processing fresh butcher-hogskins to leather is described. The procedure followed was essentially a process that was developed on brined skins and described in a previous publication, with modification. Sodium hydroxide (0.25 percent) was added in the relime step and a nonioinic surfactant (0.5 percent) was added in the delime and bate step. The blue stock was then split, shaved, degreased, vegetable retanned and fat liquored. By following the procedures described, an acceptable leather with a clear grain and no grease stains was obtained. Either the added alkali or the added surfactant alone, also gave acceptable leather, but the use of both appeared to result in the cleanest grain.
The study demonstrates that the pigskin process developed earlier at this Center on brined skins which uses short floats, lowered amounts of water and chemicals and shortened process time can be modified to handle fresh butcherhogskins. The importance of using fresh pigskins is that it gives additional significant savings of water and handling time when compared to the use of salt cured stock. It also provides the opportunity to maximize by-product recovery and to eliminate the dissolved solids pollution resulting from salt curing at the curing plant and tannery. |
