In the lab of tannery skins of the FCP, the ESPOCH was the comparison of tanning with extract of plant polyphenols in Caesalpinia Spinosa, with a mineral tanning of sulfate of chromium for goat skins, i.e. 2 treatments with 7 repetitions each one, and in two consecutive runs a total of 28 experimental units were modeled under a completely randomized design in bivariate array. The results indicate that the most suitable tanning was to use plant polyphenols Caesalpinia Spinosa, (tara), since it is possible to obtain very good classification leathers, nothing that the percentage of tensile strength and elongation (72.12%), (333.24 N/cm 2 ), not recorder differences however numerical superiority can be seen in (T1) vegetable tanned leathers, as for shrink temperature, (92,86ᵒ C), being highly significant differences. The sensory evaluation determines greater fullness (4.50 points), using tanning plant (T1), meanwhile to fineness of flower (4.57 points) and fullness (4.71 points) sulfate of chromium. The Economic evaluation determines that tanned with vegetable extracts (T1), provides greater profitability to the production process since the benefit ratio being cost of 1.37, it indicates a gain of 37%; so it is recommended using the vegetable tanner leather with vegetable extracts of the tara already which improves the characteristics of the leather, allowing artisans of a high raw material that reflect on the articles end as it is footwear.Downloads
