Obtención de Cuero Flor Rectificada con la Utilización de tres niveles de Ligante de Impregnación para la Fabricación de Calzado

Abstract

In the leather tanning Laboratory, Faculty of Animal Science of ESPOCH was obtained corrected grain leather for shoes, using three binder levels impregnation, the experimental units, 30 goatskins, were modeled under a completely randomized design in accordance combinatorial with three treatments, five replicates in two trials. In assessing the physical resistance of leather, highly significant differences were determined between means of treatment, the best results of tensile strength (158,20 N/cm2), lastometría (8,13 mm) and percent elongation (58,0%) was 250 g when using binder (T3). In the sensory evaluation the best response for the filling (4,60 points) and ease of fine (4,70 points) was with 200g (T1) of binder, as fully as was reported when using 250g, (T3) binder. Resistors physical and sensory trials, reported no statistical differences due treatments. When making clothing shoe with three treatments was achieved using more leather surface. The economic evaluation, the best results were obtained with 250 g of binder in the impregnation, for the benefit of the cost was 1,25, meaning that for every dollar invested was obtained gain 25 cents, or 25% of income that is superior to other productive activities. 250 g are advised to apply impregnation binder to increase the physical resistance, preventing the outbreak of the flower or breakage of the collagen fibers, when assembling the shoe.
