Abstract

The invention relates to a preparation method of a blue light luminous fiber. The preparation method comprises the following steps: firstly, mixing 0.1 to 0.5 weight part of triphenyl iodine hexafluoroantimonate photoinitiator with 5 to 10 weight parts of SrAl2O4:Eu<2+> and Dy<3+> luminescent material and 20 to 40 weight parts of fiber forming polymer base material, granulating by adopting a twin-screw granulator to obtain luminescent master batches for spinning; secondly, pre-drying the luminescent master batches for spinning obtained in the first step and then performing melt spinning to obtain the blue light luminous fiber. The luminous fiber obtained by the preparation method absorbs visible light for 10 minutes, and can continuously emit light in a dark state for 10 hours or above; the luminous intensity can maximally reach 1.5 to 3cd / m<2>; emitted blue light of 430 to 450nm is one of three primary colors; any one complex color luminous fiber can be prepared by compounding the blue light luminous fiber with one or two of a red luminous fiber and a green luminous fiber, and the application field of the luminous fiber can be widened.

Description

technical field [0001] The invention relates to a preparation method of a blue luminous fiber, in particular to a preparation method of a blue luminous fiber capable of emitting 430-450nm blue light in the dark, and belongs to the technical field of functional textile material manufacturing. Background technique [0002] Rare earth strontium aluminate luminous fiber is a new type of environmentally friendly and energy-saving fiber. It is mainly made of rare earth materials as illuminants through special spinning technology. It is widely used because of its good luminous performance in the dark or at night. However, the wavelength of the emitted light is between 520 and 540nm, and the spectrum is distributed in the yellow-green light region, so the monotonous emission color has become a major problem in application. At present, the main raw materials of the existing blue luminous fibers are metal sulfides and silicate luminescent substances, and the initial afterglow brightne...
