Alkaline earth metal type of aluminate luminescent material can be excited by the energy of the light in the environment, and emitted the long-wavelength light in the darkness . The luminescent material can be applied to the textile fields. This study is to investigate the effect of the formability of the photoluminescent fibers by varying the concentration of the dispersing agent and the luminescent pigment in the master batch. The results show that the 2% dispersing agent concentration and the 20% luminescent pigment concentration can maintain the difference of pressure below 2bar and the luminescent pigment become the better dispersing condition. The photoluminescent sheath-core fiber, made by melt-spinning, shows the luminous intensity will reach 106mcd/m^2. The average tenacity of the luminescent fiber will reach 1.71g/d and the elongation is 45%.
