| Résumé : |
Liming is one of the key steps in the leather-making process - to remove hair and non-collagenous materials from the hide and, more importantly, to open up the fibrous structure for tanning and lubrication. However, the leather industry lacks an effective means to identify proper liming conditions that produce a sufficient degree of opening-up. As part of our effort to investigate the applications of acoustic emission technology to leather manufacture, we have examined the feasibility of using the acoustic emission (AE) technique to measure the degree of opening-up of leather produced with various liming times. Leather samples were stretched and contacted with an acoustic sensor to collect various acoustic quantities. Observations showed that a change in the degree of opening-up of the fiber structure associated with the increase of liming time can be detected by a history plot of acoustic emission counts. The samples with less than 24 hours liming show a relatively smooth history plot, whereas the samples with a liming time greater than 24 hours produce a pronounced saw-shaped pattern, and the longer the liming time, the more erratic the pattern becomes. This behavior mirrors the change in the extent of opening-up of the fibrousstructure engendered by the lime action. We have concluded that a qualitative association exists between the degree of opening-up of leather and the acoustic counts patterns measured by an AE analyzer. The results of this work may provide a route tomonitor the degree of opening-up of leather. |
