NOVELTY - Preparing antistatic ultraviolet fiber comprises preparing spinning level slice by melting and blending the nano functional powder and PA6 polyamide material on the basis of double-screw rod; preparing PET spinning level slice by the way of dissolving the uvioresistant auxiliary agent and dibutyltin in ethyleneglycol in situ polymerization way and performing composite fiber spinning by PET screw rod for processing the PET material and the PA6 screw rod for processing PA6 for double-component spinning. USE - The method is useful for preparing antistatic ultraviolet fiber. ADVANTAGE - The method has good anti-ultraviolet ability, antistatic capability and good mechanical property, satisfies the requirement of weaving, increases the additional value of the fiber and fabric.
