The Born cross-sections and effective form factors for process $e^+e^-toXi^-bar{Xi}^+$ are measured at eight center-of-mass energies between 2.644 and 3.080 GeV, using a total integrated luminosity of 363.9 pb$^{-1}$ $e^+e^-$ collision data collected with the BESIII detector at BEPCII. After performing a fit to the Born cross-section of $e^+e^-toXi^-bar{Xi}^+$, no significant threshold effect is observed.
