摘要: In this study the effects of enzymatic hydrolysis on drawn polyesterfilament yams were investigated . Two multifilament with different draw ratiosat temperatures and then they werehydrolyzedin similar conditions The studied by means measuring weight loss, moistureabsorption, tenacity,elongation-at-break,IR spectrum scanning electron microscope Results research showed that decreasesthe polyesterhanks less than 0.5%. strength loss due to reached a maximum 10%, whereas elongation-at-breakof samples decreases 7-25% hydrolysis. Hydrolysis also increased moisture absorption polyester up 50%. FTIR spectra as well other results show effect is limited surface substrate more affected increase in area rather drawing.
