Abstract

Polyester fabric was modified with two nitrogen compounds, i.e., choline chloride(CC) and ethylenediamine(EDA) to enhance its absorbency. Thermosol fixation at $220^{\circ}C$ was used for CC treatment whereas a simple immersion at $25^{\circ}C$ and $35^{\circ}C$ was employed for EDA. To evaluate the absorbency, spreading area of water drop on the specimen was measured with the computer-interfaced image analysis system. We developed semi-empirical model to rationalize the absorbency results. Dyeing with acid dyes and tensile strength test were carried out to characterize the modified polyester. The results indicated that CC treatment could be highly feasible in hydrophilic modification of polyester without reduction in mechanical property that was often shown with a conventional alkaline treatment such as EDA.
