Résumé : |
Leathers fatliquored with sulfited fish oil were irradiated with microwave at various intensities, then their physical properties and the microstructure of collagen fibers were investigated to show the roles of microwave field. As confirmed, the free and capillary moisture in leather were firstly removed by microwave radiation, accompanying with diminution in area. However, the hydrothermal stability of leather was scarcely altered. Scanning Electron Microscope images indicated that the dispersion of collagen fibers was not destroyed with microwave exposure. In addition, the characteristic D-periodicity and microstructure for the collagen were changed little as revealed by Atomic Force Microscope and X-ray Diffraction studies. Furthermore, there was some improvement in the softness of leathers because of migration of oil and its uniform distribution. These results could be helpful for understanding the roles of microwave technique in leather industry. |
