Abstract
Investigation of Thermodynamic-Kinetics of Polyester Dyeing with Liquid Disperse Dye
Highlights
Polyethylene terepthalate is one of the most important synthetic fibers used today
Disperse Orange 30 in commercial form and liquid form developed from its crude form without mechanical grinding were investigated in terms of their thermodynamic and kinetic parameters
The liquid form was found to have properties comparable to that of commercial form. This novel form of disperse dye without mechanical grinding proposes a formidable alternative to the dyes industry
Summary
Polyethylene terepthalate is one of the most important synthetic fibers used today It is the most utilized polyester commercially [1]. The process of grinding is time consuming and significantly contributes to the cost of finished dye powder since it is energy intensive It would be beneficial for the dyestuff manufacturing industries if alternative route is developed wherein above-mentioned demerits are eliminated. In these regards, manufacturing of disperse dyes without mechanical grinding in liquid form could be an enlightening approach. Modern process houses use automatic color kitchen to prepare requisite dye solutions in liquid form. The phenomenon of dusting of dyes gets eliminated in this case
