| Résumé : |
We investigated a drying method that will enable leather to be dried under vacuum and stretch sequentially to improve area yield. Vacuum drying offers fast speed at a low temperature, which would be advantageous to heat-vulnerable chrome-free leather. Adding a toggle action after vacuum drying could significantly increase area yield. Using a statistical experimental design, we formulated regression models describing how drying variables affect mechanical properties and area yield of chrome-free leather tanned with glutaraldehyde. An effort was also made to estimate the effects of conditioning, staking, and drum milling on the area retention gained by toggle stretching. This study showed that the direction the stretch was applied had a significant effect on the area retention. Results also indicated that conditioning and staking have little effect on area retention, whereas the drum milling caused a significant drop in area retention. Our study also showed under an optimal drying condition, a 12% increase in area yield with good properties can be achieved. |
