1. An intrinsic fluorescent green fiber, comprising:
98.00 parts by weight to 99.00 parts by weight of a carrier, wherein the carrier comprises polyethylene terephthalate;
0.10 parts by weight to 0.20 parts by weight of a yellow colorant, wherein the yellow colorant is a fluorescent yellow dye, and when a content of 0.10 wt % to 0.20 wt % of the yellow colorant and a balance of the carrier are mixed together to form a yellow fiber, a L* value, an a* value, and a b* value of the yellow fiber in a L*a*b* color space are respectively between 101.27 and 101.72, between −17.61 and −13.47, and between 89.84 and 108.79;
0.08 parts by weight to 0.20 parts by weight of a blue colorant, wherein the blue colorant is a fluorescent blue pigment, and when a content of 0.08 wt % to 0.20 wt % of the blue colorant and a balance of the carrier are mixed together to form a blue fiber, a L* value, an a* value, and a b* value of the blue fiber in the L*a*b* color space are respectively between 55.60 and 66.80, between −22.69 and −22.70, and between −37.50 and −31.80; and
1.00 part by weight to 1.50 parts by weight of a titanium dioxide.
