| Résumé : |
In this paper, samples of un-tanned cattlehide collagen fibers, chrome tanned cattlehide collagen fibers, and glutaraldehyde tanned cattlehide collagen fibers are prepared, and soaked in man-made sweat solutions. Studies of their thermal degradation behaviors are completed, and the factors affecting their thermal degradation behaviors are discussed. Both methods of Flynn-Wall-Ozawa and Šatava-Šesták are applied in the study of thermal degradation kinetics of these samples. The results indicate that, after being soaked in sweat for 15 days, the thermal degradation activation energies of all samples change in different degrees. Sweat-soaking process affects the thermal degradation activation energy of chrome tanned cattlehide collagen fibers the most obviously, and the chrome tanned sample is the worst in sweat resistance in the three samples studied here. The interaction between sweat and different modified cattlehide collagen fibers are discussed. |
