Obtención de un acabado semianilina en pieles caprinas curtidas con tara y aluminio con la aplicación de diferentes niveles de productos compactos

Abstract

In the tannery laboratory of the Faculty of Animal Sciences, semi-aniline finishing of tanned goat skins with tare and aluminum was performed, using different levels of compact product, 3 treatments were used that constituted the different levels of compact product ( 450, 475 and 500 g), with 8 replicates, and modeled under a Completely Random Design. The highest results of percent elongation (62,50%), and dry rub resistance (182,88 cycles), were recorded using 500g of compact product; meanwhile, the best tensile strength (2217,29 N / cm2) was reached when using 450 g of compact, meeting the three physical resistances with the quality requirements of the Spanish standards IUP 6 and IUF 450 (2012). The best sensorial ratings of fullness and power of coverage with 4,75 points in both cases were obtained when using 500 g of the compact product; While the best fullness when using 450 g of the compact product, achieving an excellent grade in each of the evaluated characteristics i.e. a very soft material, whit a good drop and with the ideal filling for the preparation of the finest items. In the benefit / cost indicator, the highest income was reported in the T3 treatment (500 g), due to its higher price because of its enhanced quality since the cost benefit ratio was 1,34 that is to say in every dollar invested, it is expected to yield 34 cents.
