| Résumé : |
The chemical treatment leather with fatliquor and physical treatment of staking produce similar esthetic results. The effects of two such different treatments on the structure of the leather, however, and perhaps various other responses to deformation, are expected to be different. The equivalence of fatliquoring and staking were investigated by comparing the effects of the treatments on the stress-strain curves and the acoustic emission observed during tensile testing. It was found that staking affects only the first 25% of the elongation at break, lowering the initial modulus, while fatliquors affect the whole stress-strain curve. The initial part becomes concave upward instead of downward, and the elongation and stress at failure are greater. Acoustic emission from leather that was merely staked was suppressed only at small elongations, while it was smaller at all elongations from leather that had fatliquor. The results are shown to be consistent with a domain model of deformation. A nondestructive determination of the elongation of leather at tensile failure, based on acoustic emission, is derived from the observations. |
