Resumen
The three level evaluation of chrome sulfate in the fixing aniline to dye wool was
carried out ¡n 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 triáis 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 distensión 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 distensión of 4.22 mm. The same way to evalúate 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 cosí 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.
