Synthesis and Application of Easy Hydrolysis Degradable Polyester

An easy hydrolysis degradable polyester (EHDP) is synthesized; the fiber produced from which can be hydrolyzed by dilute basic solution easily. The properties of these kind polyesters are measured. The results show that this kind polymer is suitable to be spun into filament The EHDP can be spun into staple fiber and manufactured into non-woven fabric. This fabric is used as disposable clothes. In composite spinning, the PET (polyethylen glycol terephthalate) or PA (poly amide) is used as continuous phase, and EHDP used as dispersed phase. Then the fabric of this kind fiber is treated by basic solution; the ultra-fine fiber fabric is obtained. The fineness of the fiber is about 0.045 dtex. In blend spinning, EHDP is mixed with polypropylene (PP) to produce hollow fiber with micro-holes hi radical direction. This fiber is a usable material in filter especially in medical use.
