| Résumé : |
In this paper, the dry heat resistance of hide and leather is studied by means of thermal platform microscope. Such factors as drying, tanning, types of tanning agents and tannage degree that may affect the dry heat resistance of hide and leather are included. Changes and mechanisms of samples when dry heated are analyzed and discussed. We use KCrSO4, CrCl3, Cr(NO3)3 and Sugar reduced chrome liquor as tanning agents to study tanning effects on the dry heat resistance of hide fiber. It can be found that chrome tanning may reduce the initial shrinkage temperature, and increase the final shrinkage temperature. It is to say that chrome tanning may broaden the shrinkage range of hide fiber. Dry heat resistance of hide fibers with different degrees of tanning is also studied. Shrinkage ratio of hide fiber tanned with KCrSO4 decreases with increasing KCrSO4 concentration in the tanning liquors. Hide fiber tanned with sugar -reduced chrome liquor posseses the best dry heat resistance in all the four kinds of tanned hide fiber samples studied. |
