| Résumé : |
A new sulphonated melamine-urea-formaldehyde (MUF) polycondensation resin of relatively low melamine content, prepared according to a sequential formulation, has been shown to be highly effective when coupled with different natural vegetable tannins to produce leather with the same good characteristics of leather prepared with chrome salts. The variation of leather colour as a function of ageing time on prolonged irradiation with UV light of the leather produced with different combinations of veg tannins/MUF resins has been reported. A predictive model and equation for the variation of leather colour as a function of ageing time has also been established and is presented. The variation of leather colour as a function of ageing time has been correlated with both the antioxidant capability of pure tannins in solid form, and with their antioxidant capability in situ within the leather prepared with them. |
