Poly-ether-ether-ketone(PEEK)fiber was prepared via melt spinning process.The structure and properties of PEEK fiber were studied.The results showed that the longitudinal surface of PEEK fiber was relatively smooth with a small amount of gel particles,and the cross section of PEEK fiber was almost circular and compact.The crystallinity and orientation degree of PEEK fiber were inpreved and the aggregation structure was more perfect and stable after heat drawing and setting.The PEEK fiber exhibited the breaking strength above 3.5 cN/dtex,elongation at break of 30%,dry-hot shrinkage of 2%.The PEEK fiber had the strength retention rate above 70%after continuous use for 7 d at 300 ℃ and remaining 56.45%after ultrosonic irradiation for 6 d.The PEEK fiber had the corrosion resistance to chemical solvents.
