Curtición de pieles caprinas ( capra hircus), con diferentes niveles de oxazolidina, en combinación con sulfato de aluminio para la elaboración de calzado de dama.

Abstract

Obtaining leather for ladies' shoes through mixed tanning; organic and inorganic. Twenty-four goat skins (Capra Hircus) of the creole ecotype were used, distributed in 3 treatments, 8 repetitions and modeled with completely random design, made in the tannery laboratory of the ESPOCH, Riobamba Canton, Chimborazo Province. The Kruskal Wallis test was used for the statistical analysis of checking the tensile strength, elongation and lastometry, the tests were carried out in the Tannery Laboratory of the Faculty, carried out in the laboratory of Animal Sciences. Sensory tests of touch, fullness, softness and roundness were carried out, which were carried out by a judge. Treatment with oxazole idine at 7%, record greater resistance to tension (2274.75 N / cm2), better percentage of elongation (86.88%), and higher tonometry was determined by tanning with 6% oxazolidine, (9.86 mm). The evaluation of the sensory scores determined the highest scores in the treatment with oxazolidine at 7%, fullness (4.38 points), softness (4.75 points) and roundness. (4.5 points), reaching, qualifications of excellence according to the Spanish Association in the Leather Industry: Technical Standards of leather and shoes 2a. ed. Barcelona, I conclude that these two treatments turned out to be the most appropriate. It was appreciated that the cost benefit ratio was greater in the treatment with 7% oxazolidine, which reached a value of 1.42 ctvs., That is, for each dollar invested, there was a profit of 42 cents. I recommend using this treatment since you get high performance leather with a beauty of insuperable degree that improve the acceptance by art of consumers.
