<p>The present invention relates to a method and an apparatus for manufacturing a polyester monofilament having two kinds of colors. The method for manufacturing a polyester monofilament having two kinds of colors comprises: a first step of putting a first polymer into a first extruder to be extruded and putting a second polymer into a second extruder to be extruded at the same time; a second step of injecting a first colorant and a second colorant respectively through a first discharge pipe and a second discharge pipe of the first extruder and the second extruder respectively; a third step of allowing the first polymer and the second polymer to be colored and discharged into a first gear pump and a second gear pump respectively; and a fourth step of mixing a first raw material and a second raw material, which are discharged respectively from the first gear pump and the second gear pump, by a spinning pack and spinning a yarn. The colorants are injected right before the raw materials, discharged from the first and second extruders, pass through a filter and are about to be injected through the first and second gear pumps, wherein the first and second colorants are one selected from the group consisting of anthraquinone, phthalocyanine, and quinacridone and are a mixture of a triazine-based UV absorber and a colorant.</p> |
