【 摘 要 】

This paper focuses on the analysis of goats leather to identify the physical and mechanical characteristics after toning. Sixteen male crossbred Alpine goats, with four animals from 180 days old by slaughter, were used. Slaughter intervals of 45 days were used. The skins were tanned and re-tanned, and from the breather the proofs from the dorsal, palette, ventral, hind and lateral regions, were taken, in the following directions: parallel and perpendicular to the tail-skull axis, so that the physic-mechanic studies could be performed: distention of the "flower" in the lastometer, progressive tearing; resistance to traction and chemical analyses of fat, chrome, pH and differential code. Animal age showed positive effect on traction resistance, with high values to goats at 315 days old. The region and position of all animals studied shower significant effect on the four reach ages, reaching the minimum reference value of 80 kgf/cm. Bather resistance to distention of the "flower" from the goats were superior to the minimum of 7 mm, showing the great elasticity of the bather, with no effect of age or region.
