| Résumé : |
Chrome tanned cattlehide collagen fibers were retanned and fatliquored by different chemicals. The samples were immersed in artificial sweat for 3 to 15 days. The sweat-soaked collagen fibers were then heated in air. The shrinkage temperature (Ts) and shrinkage ratio were recorded to characterize the thermal stability of the collagen fiber samples. It was found that the shrinkage ratio decreased after the processes of retanning and fatliquoring. After sweat-soaking treatment, the shrinkage temperature of the retanned and fatliquored collagen fibers was decreased and shrinkage ratio was increased, indicating an impaired thermal stability. The Ts decreased with the increase of the sweat soaking time. The chrome retanning liquor and GTA retanned collagen fibers exhibit slow decrease of shrinkage temperature with the increase of sweat-soaking time, showing great resistance to sweat. Compared with that fatliquored by other fatliquoring agents studied, collagen fibers fatliquored by neats- foot oil has better sweat-resistant property. |
