Research Evidence
Aim: To investigate the synthesis of eco-friendly alkyd resins from sunflower oil using microwave heating and evaluate their performance as binders in textile printing pastes.
Method: Experimental research and comparative analysis
Procedure: Alkyd resins were synthesized from sunflower oil using microwave heating, varying oil length and catalysts. The properties of these resins (acid value, glass transition temperature, solubility, IR data) were evaluated. These synthesized binders, along with a commercial binder, were then used to formulate pigment printing pastes. The printed fabric properties were assessed and compared.
