Curtición de pieles caprinas con la conbinación de Caesalpina spinosa (Tara) más un tanino sintético

Abstract

The goat hide tanning combining Tara (Caesalpinia spinosa) with synthetic tannins was evaluated in the Skin Tanning Laboratory of Animal Science Faculty of Escuela Superior Politécnica de Chimborazo (ESPOCH). The experimental units were 24 goat hides distributed under a complete randomized design. The results showed the most appropriate level of Caesalpinia spinosa was 16% for women’s footwear, since it was possible to improve the leather quality, avoid returns, guarantee a high quality product, get higher tensile strength (3 703.10 N/cm2) and determine elongation percentage (79.6%). On the other hand, the leather in T1 got the best resistance at high temperatures (85.75°C). The sensory evaluation showed the leather in T3 was the best determining the best softness and size of flower (4.75); it is excellent according to the scale posed by Hidalgo, L. (2016), whereas the leather in T1 showed the best fullness (12%), which is more accepted by manufacturers and customers. Of the cost/benefit analysis, the highest levels of Tara were more profitable, since 0.24 cents can result in return of every dollar invested. This will help Ecuador reactivate its economy.
