Abstract

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