Abstract: The conjugated staple fiber of polyester (PET) and polypropylene was divided by the alkaline hydrolysis under the high pressure conditions over 100 MPa. The decomposition of the sea element, PET, was accelerated with the temperature and pressure. The addition of the cationic surfactant also enhanced the reaction rate when the concentration was more than 0.5 g/L. At high surfactant concentration, the acceleration effect was saturated. The high-pressure alkaline hydrolysis gave the fine polypropylene staple fibe…
