Résumé : |
Leather finishing is a very important operation in leather manufacture. Various chemicals are used in leather finishing. The introduction of nanoparticles in leather finishing has revolutionized the leather industry. They are used to produce various types of leathers and to meet the end user requirements. The aim of the work was to coalesce the fields of leather technology and nanotechnology for obtaining superior quality of leather with improved performance. Synthesis of titanium metal oxide nanoparticles was done by sol-gel process and used in leather finishing mixture as coating ingredients. The physical and chemical properties of the synthesized metal oxide nanoparticles were characterized by TEM, FE-SEM, EDAX, FT-IR and XRD. The surface morphology of the nanoparticle coated leather was evaluated by AFM. The finished leather was assessed for its film adhesion to evaluate the strength of the bonding between the leather surfaces and finish coating. The conventional finish system experience finish adhesion issue in due course of time. The titanium metal oxide nanoparticles coated leather exhibited increased adhesion property. TiO2 nanoparticles increased the intermolecular linkages between the leather finish coating and the leather surface. |
