Glass fiber and method for producing the same

A method for producing a glass fiber, comprising:

• a covering process implemented by covering a plurality of zirconia powders onto a plurality of surfaces of a plurality of inorganic particles to form a plurality of modified inorganic particles;
• wherein, based on a total weight of each of the modified inorganic particles being 100 wt %, a content of the zirconia powders is between 0.01 wt % and 5 wt %, and a content of the inorganic particle is between 95 wt % and 99.99 wt %;
• a sintering process implemented by sintering the modified inorganic particles in a nitrogen atmosphere under a temperature of between 400° C. and 1,000° C.;
• a mixing process implemented by mixing the modified inorganic particles that are sintered into a glass raw material that is in a molten state;
• and
• a drawing process implemented by drawing the glass raw material, in which the modified inorganic particles are mixed, to form a glass fiber.
