Super Engineering Plastics (SEPs) are at the highest end of the spectrum, generally with very high strength and thermal resistance. It is used in high temperature, high stress, in harsh environments, and low to medium volume production. High thermal resistance SEPs fiber were prepared by melt-spinning process of polysulfone (PSU), polyethersulfone (PES), polyetherimide (PEI) and PSU with poly(arylene ether)sulfone (PAES). The PSU, PES, and PEI were prepared at 330 to 380℃ with a winder speed 260 to 2,000 mpm. The characteristics of SEPs fiber was studied by SEM and UTM. And those SEP fibers applied to artificial hair. SEPs fiber exhibited superior flammability, heat resistance, curl forming, and melting dripping fire retardant than PET or PVC artificial hair. Herein, the SEPs fiber with excellent flame retardancy and functional performance had practical value for application in the field of synthetic artificial hair. |
