A fiber masterbatch including a polyetherimide, a polyethylene terephthalate, and a polyimide is provided. A glass transition temperature of the polyimide is between 140 DEG C and 170 DEG C, a 10% thermogravimetric loss temperature of the polyimide is between 500 DEG C and 550 DEG C, and when the polyimide is dissolved in N-methyl-2-pyrrolidone and a solid content of the polyimide is 15 wt%, a viscosity of the polyimide is between 80 cP and 230 cP. A melting spinnindg fiber obtained by using the fiber masterbatch is also provided. |
