| titleOfInvention | Recycled polyester short fiber using waste polyester and its manufacturing method |
| abstract | The present invention is to prepare bis-2-hydroxyethyl terephthalate (BHET) by mixing waste polyester and ethylene glycol (EG) in polyester short fiber using recycled polyester produced by depolymerizing waste polyester. A regenerated polyester chip manufacturing step comprising a depolymerization step and a polycondensation step of polycondensing the bis-2-hydroxyethyl terephthalate (BHET) with regenerated polyester; A fiber manufacturing step of manufacturing a fiber by melt spinning and stretching the regenerated polyester chip; A heat treatment step of increasing the degree of crystallinity by heat-treating the prepared fibers on a roller surface at 70 to 250 ° C. for 5 to 30 seconds; And it relates to a recycled polyester short fibers using the waste polyester comprising a cutting step of producing the heat-treated fibers into short fibers and a method for producing the same. |
