| Résumé : |
A new tetrakis hydroxymethyl phosphonium sulphate (THPS)-aluminum combination tanning system has been developed. The optimum dosage of THPS was 2.0%. The amount of THPS and basic aluminum chloride was optimized at 2.0% and 3.0% (basing on the weight of pelt). The influence of ligands on the shrinkage temperature (Ts) of leathers was also studied and the Ts of THPS-aluminum combination tanned leathers was above 88°C. Color fastness to dry/wet rub of THPS-aluminum combination tanned leathers was much better than the relevant color fastness to dry/wet rub of leathers tanned with THPS alone. Scanning electron microscopic studies showed that the fiber weave of THPS-aluminum combination tanned leather was much closer than leathers tanned with THPS alone and the fiber weave of THPS-aluminum combination tanned leather was closer(tighter) with an increase of amount of basic aluminum chloride. Hence, with the increase of the amount of basic aluminum chloride, the reactive ability of basic aluminum chloride with collagen fiber was stronger and the softness became worse. Degradation rate of soiling for the THPS-aluminum combination tanning leather was much quicker than that of chrome tanning leather. Through SEM analysis, the surface structure of leather which was not degraded was more regular than the leather degraded for 30 days. Meantime, the of THPS-aluminum combination tanning leather degradated much more easily than the chrome leather, which suggested a benefit for the sustainable development of the leather industry in future. |
