Résumé : |
The authors of this article have observed some excessive plumping in the flanks of limed split hides that has been correlated to looseness in crust leathers. But these observations only accurately predict downgrading in less than 30% of the hides we have pulled from production and processed through to leather, suggesting a tenuous connection at best. We have also seen a strong correlation between sammed wet-blue looseness, as measured using a modified TM 174 technique, and crust looseness in 32 regions of 1,000 hides followed through commercial production.
The main issue with all these techniques is that they cannot identify looseness in the raw material. Other studios in this project are looking at the chemical composition of base and tight hides, and follow a similar protocol to the one adopted in this study, where five regions of suspected loose hides are sampled and the remaining hide processed through to leather to identify whether it is actually base or not.
Our observations, from investigating looseness in cattle hides identified at the slaughter plant through to crust leather, is that looseness cannot be readily observed from information gathered on animal condition, breed, age or gender, but does become more obvious once the hides are processed, and can be readily seen in the cross-section of processed hides. |
