Sistemas tintóreos isorreactivos.

Resum


An isoreactive dyeing system is defined as the system where the sorption rate is kept constant along the whole kinetical period. A theoretical study of this condition is carried out from the modified kinetical equation Cegarra-Puente and from Arrheniu's equation. The conditions of temperature-time to apply on dyeing are found, from the Isoreactivity equation,in order to get a constant sorption for different sorption times. Finally, the agreement between the theoretical values and those found experimentally in the dyeing systems: wool-acidic dyes, fibranedirect dyes and acrylic fibres-cationic dyes is verified.
