Vapeur d'eauIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : An acrylic resin and an acrylic-resin/nano-SiO2 composite prepared as coating agents were applied in leather finishing and various properties of the finished leathers were determined. The results show that the physicalmechanical properties and cleaning properties of the leather samples finished with the acrylic-resin/nano-SiO2 composite increase noticeably. As examples, water vapour penetration and air permeability improved by 11.5% and 15.4%, dry rub fastness and folding strength [flexing] of the leather finished with the composite resin were also, to a degree, superior to that finished by the acrylic resin. The surface morphology observed by SEM (scanning electron microscope-energy spectrum of X-ray analysis) and AFM (atomic force microscope) indicated that the surface of the leather finished with the composite resin is smoother than that of leathers finished with the acrylic resin.

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
Tannage minéralTannage dans lequel interviennent différents minéraux. Le plus répandu est le tannage aux sels de chrome, mais aussi à l’aluminium
Tannage organiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Surfactants play an important role in the preparation, characterization and application of nano materials because of their particular structure and properties. In this paper, the authors introduce the application of surfactants in nano leather chemicals on the basis of our study on nano-tanning agents and nano-coating agents. Further application prospects for surfactants in this field is forecast. Note de contenu : - Applications in preparation of nano tanning agent

Tannage au chromeIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A retanning agent was synthesized from chrome-shaving hydrolysate modified with vinyl monomers. The chrome-shavings were hydrolyzed without de-chroming and were then modified by grafting with vinyl monomers. To provide proof of grafting, the modified hydrolysate was identified by indanthrone, and infrared spectroscopy (IR) The amino acid composition of the hydrolysate and modified hydrolysate were analysed. The results show that the vinyl polymer had been grafted on the polypeptide chains of the hydrolysate with covalent bonds.
This protein retanning agent containing chrome was beneficial to the utilization of chrome shavings. Good stretch and filling properties were obtained from leather retanned with this agent.Note de contenu : - EXPERIMENTAL PROCEDURE : Hydrolysis of chrome-shavings - Comparison application experiment with the modified chrome shavings hydrolysate - Proof of grafting modification of chrome-shavings hydrolysate
