| titleOfInvention | Recycled polyester short fiber using waste polyester and its manufacturing method |
| abstract | The present invention In the polyester short fiber using recycled polyester manufactured by depolymerizing waste polyester, the depolymerization process of mixing waste polyester and ethylene glycol (EG) to produce bis-2-hydroxyethyl terephthalate (BHET), A regenerated polyester chip manufacturing step comprising 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 dried regenerated polyester chip; A first heat treatment step of increasing the degree of crystallinity by heat-treating the prepared fibers on a roller surface at 170 to 220 ° C. for 5 to 30 seconds; A crimping step of imparting crimp to the heat treated fiber; A second heat treatment step of drying and heat-treating the crimped fiber in a hot air of 65 to 175 ° C. for 5 to 30 minutes; 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. |
