In order to improve the UV protection performance of polyethylene terephthalate (PET) fiber,the UV-resistant PET fiber was prepared by blending CeO2-TiO2 functional composite powder at a mass ratio of 1∶1 with PET slices by melt spinning.The properties of UV-resistant extinction PET fiber were tested and analyzed by UV-Vis near infrared spectrometer,differential scanning calorimeter (DSC),sound velocity orientation measuring instrument,yarn tensile tester and textile sun protection index analyzer.The results showed that with the increase of the mass fraction of functional powder,the crystallinity of the fiber first decreased and then increased.The mechanical properties of the fiber decreased,but it could still remain above 3cN/dtex,which met the fiber requirement for clothing.When the mass fraction of functional composite powder exceeded 1.5%,the moisture regain rate of the fiber was improved from 0.41% to about 0.61%,the UPF of its fabric reached 372+,the UVA was less than 3.67%,and the UVB reached the minimum value of 0.05%,which could achieve excellent anti-ultraviolet effect in both normal and wet conditions.At the same time,the extinction performance was also obviously improved.
