Tannage au chrome
Tannage combinéLe tannage combiné se dit des tannages qui allient deux familles ou genre de tannage pour obtenir un résultat additionnant les qualités complémentaires des tannins mis en œuvre par exemple Chrome-Végétal ou Chrome-Synthétique

| Résumé : |
In the present investigation, a cleaner and eco-friendly method to leather tanning process based on a novel pre-tanning agent (Q16) has been developed. Q16 was synthesized by cyanuric chloride and p-aminobenzoic acid, then detected by Fourier transform infrared (FUR). The combination tannage process of Q16 and chrome (Q16-Cr) was optimized. In comparison with combination tannage of. F-90-Cr and traditional chrome tanning methods, the physico-chemical characteristics including shrinkage temperature, rnechanical properties and organoleptic properties of the tanned leather were analyzed, the micro-morphology of grain surface and cross section which reflect the dispersion and texture of fibre were evaluated. The distribution of chromium in the cross section was detected by Dispersive X-ray Analysis (EDAX), and the chromium concentration was also determined by Inductively Coupled Plasma-Atomic Emission Spectrometry (AES-ICP). The results are shown that the Q16-Cr-tanned leather has better tanning performance even than chrome-tanned leather. The grain surface is smoother and the collagen fibres are well-dispersed. The Q16-Cr tanning method irnproves the absorption degree of chromium, and Chemical Oxygen Demand (COD) is significantly reduced. Hence, this cleaner non-salt pickling method for less chrome tanning process encourages the sustainable development of leather industry and cleaner production. |
