Comparación de tres tipos de desengrasante, en el desengrase de pieles ovinas para la obtención de cuero para confección

Abstract

The three different types of degreaser for sheep skins, for the manufacture of ciothing were evaluated in the Laboratory of Leather Tannery of Facultad de Ciencias Pecuarias, using 3 treatments, 5 repetitions and two consecutive test modeled under a design completely random, bifactoria; where the factor A, were the different types of degreasing and factor B, tests. The results indicated that using D.D. Degreaser (T3), obtained numerically higher tensile strength ((154,29 N7cm2), percentage of elongation (50,74%), and lastometría (9,23 mm), exceeding the demands of the Spanish Association of Leather (4,60 points), and softness ( 4m80 points), the better roundness is accomplished with isograss PDX, degreaser, with excellent rating according to the scale of Hidalgo, L.(2014), Economic evaluation showed the highest profitability with DD Degreaser (T3) the cost benefit was $ 9,29; for each dollar invested is expected a return of 29%. This evaluation recommended to the use the degreasing of Sheep skins DD Degeaser this product go to improve physical resistances and sensory ratings foor leather to provide to market of raw materials of optimal quality and raise the classification of jeather, which will present a best water repellency and greater aptitude for the dry cleaning
