Curtición de pieles caprinas con diferentes niveles de tara en combinación con glutaraldehído para vestimenta

Abstract

This study aimed to apply different tannin levels in combination with Glutaraldehyde during the tanning process of goat skins intended for garment manufacturing. Twelve goat hides were used, distributed among three treatments (T1: 8% tannin, 4% glutaraldehyde; T2: 10% tannin, 4% glutaraldehyde; T3: 12% tannin, 4% glutaraldehyde), with four experimental units for each treatment using a Completely Randomized Design. The statistical tests of Analysis of Variance (ANOVA), mean separation (P<0.05) through Tukey's test, and the Kruskall-Walls test were statistical tools to evaluate the results for sensory variables. Experimental measurements were conducted for physical resistances (tensile strength, percentage of elongation, shrinkage temperature) and sensory analysis (fullness, fineness, curvature) to assess leather quality.The Physical testing conducted at the Leather Tanning Laboratory of the Faculty of Animal Sciences at ESPOCH showed that treatment T3 showed the highest tensile strength (7927.97 N/cm^2), while T1 showed the best percentage of elongation (86.43%) and shrinkage temperature (81°C). Therefore, in sensory tests, T1 scored highest in fullness (5 points) and flower fineness (5 points), whereas the best leather curvature (5 points) resulted in T3. Regarding economic analysis, the findings reported that the most cost-effective option was to use 8% tannin, with a cost-benefit of 0.78 cents.
