Abstract
Polypropylene superfine fibers or cell porous fibers were prepared from the Bi-component blend fibers of polypropylene/easy hydrolytic degradation pol yester (PP/ EHDPET, by alkaline hydrolysis process. EHDPET is a kind of cop olyester that can be rapidly hydro-degraded in the hot alkaline solution. T his article discusses the kinetics of alkaline hydrolysis of EHDPET, and th e effect of catalyst, bulk ratio, and the content of PP-grafted maleic anhy dride on the alkaline hydrolysis process. Meanwhile, the morphological chan ge of the outer surface of blend fibers during this process was also invest igated by the technology of scanning electron microscope.
