Abstract

The waterborne polyurethane was synthesized by polytetramethylene glycol (PTMG) and isophorone diisocyanate (IPDI) with dimethylol propionic acid (DMPA). Physical properties of cellulose fabrics treated with 1,3-dimethyl-4,5-dihydoroxy-2-imidazolidone (DMDHI) containing waterborne polyurethane were investigated by UTM and FT-IR Spectrometer. It is known that optimized UV intensity and cure temperature are 450 Wand $170^{\circ}C$, respectively. Add-on(%) was increased with increasing concentration of resin and time. Therefore, the results showed that wrinkle recovery of the fabrics cured with UV were better than that of heat-cure. When PUD as an additive was treated together with DMDHI, tensile and bursting strength increased with increasing waterborne polyurethane concentration. Yellowness index(YI) values for UV-cured fabrics were lower than those of heat-cured ones.
