Zusammenfassung: | The present invention relates to polyester composite fibers having excellent elasticity and a preparation method thereof and, more specifically, to polyester composite fibers and a preparation method thereof, the fibers being side-by-side composite fibers having an intrinsic viscosity of 0.60-0.80 dl/g and a Leesona shrinkage (%) of 15-30% and having been prepared by means of composite spinning a first component and a second component, the fibers having enhanced elasticity, not showing glossiness and feeling excellent to the touch.
La présente invention concerne des fibres composites de polyester présentant une excellente élasticité et leur procédé de préparation et plus précisément, des fibres composites de polyester et leur procédé de préparation, les fibres étant des fibres composites situées les unes à côté des autres présentant une viscosité intrinsèque de 0,60-0,80 dl/g et un retrait de Leesona (%) de 15 à 30 % et étant préparées au moyen d'un filage composite d'un premier composant et d'un second composant. Les fibres présentent ainsi une élasticité améliorée, ne brillent pas et offrent une excellente sensation au toucher.
본 발명은 신축성이 우수한 폴리에스테르 복합섬유 및 이의 제조방법에 관한 것으로써, 보다 상세하게는 제1성분 및 제2성분을 복합방사하여 제조되는 0.60 ~ 0.80 dl/g의 고유점도 및 15 ~ 30%의 리소나 수축율(%)을 갖는 사이드-바이-사이드 복합섬유로써, 신축성이 더욱 향상되었을 뿐만 아니라 광택이 발생하지 않고 터치감이 우수한 폴리에스테르 복합섬유 및 이의 제조방법에 관한 것이다. |
