Resumo
Mathematical modeling was employed in order to optimize pad-batch process
using C. longa natural dyestuff applied in dyeing of cotton, against the
conventional dyeing by exhaustion with the same dyestuff under best applications
parameters recommended by dyestuff supplier. Ecological costs,
consumption of water, electrical, and thermal energy, were assessed. The
application of the model in the studied process versus the conventional
process demonstrated that is possible to obtain an economy of 1.418 × 10(6)
J kg(‒1) of energy, in addition to an economy of 95% in water consumption,
without significant detriment in the color fastness assessed.
