Abstract
The study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). Average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. The breaking load, tensile strength and extension of chromic tanning leather (33.0 ± 4.9 kgf, 197.2 ± 23.9 kgf/cm2 and 53.3 ± 7.0 percent) were more than alum tanning leather (27.4 ± 5.5 kgf, 161.7 ± 26.7 kgf/cm2, 46.4 ± 7.8 percent) and vegetable tanning leathers (13.0 ± 4.5 kgf, 70.7 ± 21.8 kgf/cm2 and 40.1 ± 6.4 percent). However, the best physical quality was found in the chromic tanned leather for ostrich skin proccesing related to alum and vegetable leathers.
