Manufacturing methods and multi-functional polyester fibers produced by it of complex functional polyester fiber

摘要

present invention includes the steps of a polyester master batch chip containing tungsten cesium oxide based particles is mixed-spun with ordinary polyester chips, it is cooled using a cooling apparatus comprising a central annular discharge type cooling device and the nozzle warmth heater relates fibers method for manufacturing a composite functional polyester fibers and thereby, characterized in that it comprises. Multi-functional polyester fiber according to the present invention provides excellent far-infrared radioactive, heat storage warmth, the spinning workability and stain resistance.
