| Résumé : |
Internal bovine stomachs membrane is a by-product form the slaughter house.
Quality exotic chamois leather with a grain : a different variety from an ordinary velvety chamois may be obtained if the membranes, after preliminary beamhouse operations, are pickled and pre-tanned with formalin or glutaraldehyde, followed by a cod oil tannage.
The leather was soft, stretchy (50-65.8 % elongation at break), with rapid water absorption, lightweight, yellow/light brown colour with an adequate thickness (0.7-1.4 mm) and shrinkage temperature (Ts61°C-68°C). However the water absorption was limited due to the lower porosity of the typical fibres of the membranes.
The leather processed from this non-conventional source has been found suitable for manufacturing fancy small leather goods like ladies handbags, purses wallets, and also for covering handles of tennis racquets and hockey sticks. |
