Evaluación del Amaranto en la Tintura de Lana de Ovinos con Diferentes Valores de PH utilizando Suero de Leche

Abstract

At the Tanning Lab of Cattle and Livestock Sciences Faculty of the ESPOCH, the use of the amaranth in the sheep wool dying with different pH values ​​T1 (4.0), T2 (4.5) and T3 (5.0) was evaluated using milk serum, modeled under a completely at random design with 3 treatments, four replications and in two consecutive trials. The results show that there were highly significant differences (P s0.001) between treatments, the best being T1. The physical resistances record the best values ​​for the tensile resistance (4.31 N / cm2), solidity with the daily and artificial light (4.75 pH and 4.63 mark respectively) and solidity wit washing in an aqueous medium (4.63 mark) at the pH of 4.0 (T1), with a mark of 5 points. It was observed that while the pH is lower the wool keratin doesn't change its physical characteristics, while the sense analysis of color intensity shows better marks upon using milk serum with a pH of 4.0 (T1) with a mark of 5 points. The benefit-cost was 1.27 USD. It is therefore recommended to use the milk serum with a pH of 4.0 for the amaranth colorant fixation in the sheep wool dying, because it present the best results in the physical, sense and economic analyzes.
