| Résumé : |
During the last ten years or so varions methods have been applied to the cure and preservation of rawstock. In addition to the traditional treatment with common salt, sodium chloride, in different forms, other inorganic salts have been employed for this purpose and organic biocides have also been introduced.
It is accepted that the onset of deterioration, particularly in the case of sheepskins, can readily occur if there is any significant delay between flay and cure. In support of this view it was demonstrated by Haines and Raistrick of the British Leather Manufacturers' Research Association, that a marked advantage could be gained by the application of forced cooling. They showed that, by conveying the freshly flayed skins under cold air fans, it was possible to extend the period of good preservation up to 30h without extra labour costs. It was also shown that, if further treatment such as brining or salting was applied within that period, a reliable cure with minimum breakdown could be achieved.
The need for a rapid cure to be applied as soon as possible after flaying has been confirmed by a number of workers dealing with sheepskins and with green hides. |
