The present invention relates to a method for coating by melting the master batch mixed with a thermoplastic polyester elastomer (TPE), a UV absorbing agent, and a UV stabilizer on a surface of a PBO fiber. According to the present invention, provided is a PBO fiber applicable to an extreme environment exposed to ultraviolet rays or visible rays, or required for thermal resistance or the like, by improving UV stability of a PBO fiber, reducing breakage of a chemical bond inside the fiber, and solving a problem such as strength reduction or the like. |
