Résumé : |
Prior research from this laboratory reported on the use of gelatin, alone or in combination with dairy byproducts (casein or whey), as a filler for leather. It was found that all these treatments had fully penetrated the blue stock, were not removed during washing, and had no significant effect on mechanical properties when compared to untreated controls, but did show improvements in the subjective evaluations over the controls with respect to handle, break, dye uptake, and fullness. In this present study we applied these treatments to hides that had grain properties that were characterized as being loose, more commonly known as having spring break, to see if a reduction in these undesirable properties could be realized. The treatments were applied to the butt, belly and neck areas of the hide, and these samples were subsequently retanned, colored and fatliquored (RCF). There were no significant differences between the untreated controls and treated samples with respect to mechanical properties. Importantly, however, it was determined from subjective evaluations, that those commonly inferior areas, such as belly and neck, showed improved cutting area when treated. At the same time, Scanning Electron Microscopy (SEM) was used to compare the blue stock of both poor quality hides and hides evaluated to be of better quality before and after RCF; distinct differences in fiber structure were observed, most dramatically in the belly area. Applying these treatments to low quality hides makes economic sense. Firstly, leathers are produced that present more quality cutting area, and, secondly, these renewable resources have the potential to replace petroleum feedstuffs that are increasingly becoming scarce as well as expensive. |
