Evaluación de un sistema de curtición ecológica de pieles bovinas utilizando diferentes niveles de granofin F 90

Abstract

On-site Labaratory skins Tannery FCP from the ESPOCH a system of ecological tanning bovine hides using different levels Granofin F 90 was evaluated. The number of experimental units was 24 cowhides, spread over 3 tratments with 8 repetitions each. The experimental results indicate that the tanning Granofin with 10% F90, most resistamce voltaje (1395,22 N/cm), elongation percentage (71,25%) and shrinkage temperatura (86,38C) is reached, exceeding the standards of quality of hides destined to the preparations of clothing. The sensory evaluation of cattle hides determined the highest ratings to tanning with 10% organic tanning Granofin F 90, since most fullness (4,88 points), softness (4,63 points) and roundness (4,75 points) is achieved. The use of chromium sulfate at the present time es severely restricted by the pollution caused to the environment therefore it has sougth many alternatives that minimize ampacts achieved. The use of 10% of Granofin F 90 in the tanning of bovide leather for the making of clothing provides higher economic returns and the benefit cost ratio was 1,41 in other words 41 % gain which is especially attractive considering the country´s situation requires creation of Jobs to anable the growth and stability of the national economy.
