Curtición de pieles caprinas con la utilización de tres niveles de castaño (castanea sativa) para elaboración de calzado

Abstract

In the leather processing laboratory of the FCP of the ESPOCH, the tanning of goat skins with different levels of chestnut (Castanea sativa) for footwear was evaluated. The physical resistance and sensory ratings of the leather were analyzed, which was randomly selected in three treatments (9, 12 and 15% chestnut), and each level of tanning agent was replicated 5 times, giving a total of 15 experimental units. The results were modeled in a simple completely random design, analysis of variance, Kruskall Walis test, separation of means according to Tukey, regression and correlation were used. The results indicate that the highest tension values ​​were reported by the leathers of the 9% treatment with 5930.96 N7cm2, the highest elongation with 15% with 79.43%; finally, the highest lastometry was recorded in the leathers of the 15% treatment, with 1.39 mm; However, since there are no statistical differences, it is stated that the quality of the three different levels of chestnut meets the quality requirements of the AQUEIC. In addition, the highest fullness of the 15% treatment was reported, with 4.60 points; softness 5 points; and, touch 4.80 points, reported by the leathers of the 9% treatment, stating that the quality of the leather for hunting must have the best sensorial features since it is an article that has direct contact with the skin and by not providing these characteristics it will cause discomfort in daily walking. The economic evaluation determined that by producing leathers with 9% chestnut, the highest economic profitability is obtained; since the cost benefit was 1.37, that is to say that for each dollar invested a profitability of 37% is expected, which at the present time is very encouraging.
