Curticiòn de piel caprina con la utilización de niveles de taray un porcentaje fijo de glutaraldehìdo para la obtenciòn de cuerpo para calzado

Abstract

On-site of the leather labaratory of the FCP, at ESPOCH, goat skins were tanned with different levels of rate (10, 12 and 14%). The experimental units were 36 goat skins that were modeled under a simple Full Random Design. The analysis results of physical resistance determined that the best tensile strength was (3407.74 N/CM2), lastometria (9.06mm) and greater resistance to shrinkage temperature (C 87. 920) were obtained when tanning the skins with 10 tare, as well as the best sensory rating of softness whit a weighting of 4.45 points according to the Hidalgo scale.(2016) The highest value of fullness and roundness shared a score of 4.67 points when tanning with 14% tare. The application of 10% tare gives the leather an ideal whiteness for the making of footwear in addition, to reducing the pollution caused by the tanning with chromium on different ecosystems that surround a tannery. When determining production cots the 10% tare (T1), the cost benefit ratio was 1.34. In other words, for every dollar invested a profitability pf 34% is expected, which is encouraging for the current times when the economy is in shatrpn decline, as there are no such profitable activities as the one proposed, in addition to the added value of environmental protection.
