Evaluación de tres Niveles de Sulfato de Cromo en la Fijación de Anilina para Tinturar Lana de Ovinos.

Abstract

The three level evaluation of chrome sulfate in the fixing aniline to dye wool was carried out in the FCP- ESPOCH (Higher Educative Institution) tannery lab, in order to reach the objectives were used 1, 1.5 and 2% of chrome sulfate in three consecutive trials and 5 repetitions, with a total of 45 experimental units which were analyzed under a randomized design. According to the experimental results, the usage of 1.5% of chrome sulfate allowed to register an ageing resistance with a score 3.53, a color solidness with a score 4.73 points and one distension 4.43mm, the same way it can be appreciated in the third trial the, best indicators have been obtained of wool physical properties both ageing resistance 3.33, solidness to the color 4.00 and one distension of 4.22 mm. The same way to evaluate the Organoleptic features, it could be observed a shade intensity 4.53 points, a wool fineness 4.67 and a tact 4.53 points. Finally the usage of chrome sulfate allowed to register the better cost benefit (1.24), concluding the best physical and sensorial features of wool was obtained using 1.5% of chrome sulfate. It is recommended to apply 1.5% chrome sulfate to dye the wool enhancing the product sensorial quality.
