Curticiones de Pieles Ovinas con tres Niveles de Gutaraldehidos en la Obtención

Abstract

In the laboratory facilities of tanning skins of the Faculty of Sciences of the ESPOCH livestock, there was a tannery of sheep skins with three levels of glutaraldehidos in obtaining leather for leather goods, the number of experimental units was 45 sheep skins modeled under a completely randomized design with bivariate settlement. In carrying out the analysis of variance of physical resistance by voltage (162.67 N/cm2) and lastometria (8.67 mm), there were the best results when tanning with the 12% glutaraldehyde, while the percentage of elongation higher, (82.73 % ), it was with 8% glutaraldehyde. The tan leather sheep with 8% glutaraldehyde (T1), were reported the highest qualifications in regard to the sensory analysis of fineness of flower (4.60 points), and fullness (4.73 points), registering excellent qualifications. In the report of the effect that recorded the tests on the physical characteristics and not sensorial reported statistical differences among the means. For the cost benefit analysis showed that when using the 12% of the glutaraldehyde-based profitability was higher With a value of 1.24 ; that is to say that for every dollar spent you will receive 24 cents of utility, and it is therefore recommended tanning sheep skins for leather products with 12% glutaraldehyde, to increase physical endurance, that even exceed with the quality requirements of the technical standards of the leather, in such a way that made-up articles do not present broken flower.
