摘要
Ultrafine polypropylene fibers are prepared frompolypropylene/easily hydro - degraded polyester (PP/EHDPET) blend fibers, in which file EHDPET compo-nent is degradable by treating with NaOH - H<sub>2</sub>O solu-tion. We investigated the morphology of PP/EHDPETblend fibers before and after stretching and alkalinehydrolysis. Then thermal behavior of the blend has alsobeen studied.
