Curtición de pieles ovinas utilizando tres niveles de mimosa en conbinación con el 6% de sulfato de aluminio

Abstract

In the ESPOCH FCP skin tasting laboratory, the tanning of ovine skins was evaluated using three levels of mimosa (6, 7 and 8%), in combination with 6% aluminum sulphate, using 24 hides sheep from of adult animals, modeled under a simple randomized design, using three treatments (mimosa levels), and 8 replicates. The results show that when evaluating the physical resistance of sheep skin, the most adequate 6% of mimosa option was indentified as the highest tensile strength (2081.63 N / cm2) and lastometry (10.49 mm), which far exceed the quality requirements of leather for clothing of regulatory bodies. The sensorial appreciation determined a higher acceptance for tanned hides with 6% of mimosas tanning (T1), since the highest scores of softness (4.75 points), touch (4.88 points) and fullness (4, 63 points), it allows the preservation of leather fiber and incorporates certain features of touch morbidity and elasticity making it an excellent material for de manufacture of top quality garments. The highest cost benefit was recorded on tanned skins with 6% mimosa (T1), as the nominal value was 1.21; meaning that for every dollar invested a profit of 21 cents is expected, which is interesting when compared to other similar industrial activities.
