| Résumé : |
A novel epoxide (IEGA) is synthesized using isophorone diamine (IPDA) and epichlorohydrin (ECH) as starting materials. The structure of IEGA is characterized by Fourier transform infrared (FT-IR) and 1H nuclear magnetic resonance (1H NMR). The tanning performance of IEGA is tested in ethanol from the aspects of the IEGA dosage, tanning temperature, pH value, and tanning time on shrinkage temperature (Ts) of sheep skin. It is found that under the optimized conditions with IEGA, the Ts of sheep skin tanned with IEGA is about 86°C, which is higher than normal epoxide tanned leather. Furthermore, SEM showed that IEGA tanned leather obtained better opened-up fiber structure than glycerol triglycidyl ether (GTE) tanned leather. Tanning mechanism investigation suggested that the cross-linking process should be predominately taking place among the -NH2 groups of collagen fibers by the epoxy groups of IEGA. |
