| Résumé : |
Zinc oxide (ZnO) nanoparticles were synthesized by precipitation technique and used along with cationic finishes to improve the wet rub fastness properties and flexing resistance of coated leather. The morphology, composition, and structure of the ZnO nanoparticles were analyzed using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). ZnO nanoparticles were dispersed in water and incorporated in different ratios in conventional Nitrocellulose lacquer emulsion topcoat formulation was coated on the leather surface by spray coater. ZnO nanoparticles coated leather samples exhibited improved wet and dry rub fastness and flexing resistance property. Optimum quantity up to 2-4 g/L of ZnO nanoparticles in the season was desirable for upgrading the value of leathers. ZnO nanoparticles in cationic finishing can be highly beneficial for up gradation of low-grade crust with improved fastness properties without affecting its natural look and feel. |
