Abstract

본 발명은 기계적 강도와 신도가 우수하고 생분해성이 우수한 지방족 폴리에스테르 플랫얀을 얻음을 목적으로 하며, 그 기술구성은 산성분으로서 97~99.9몰%인 숙신산 또는 그 에스테르 화합물, 0.1~3목%인 말단카르복시기를 3개 이상 갖는 저분자량의 유기화합물 또는 그 부수물, 디올성분으로서 1,4-부탄디올 또는 에틸렌글리콜 중에서 선정된 1성분이 70~97몰%, 네오펜틸글리콜이 3~30몰%로 이루어진 혼합물을 에스테르화 또는 에스테르 교환 반응 및 축중합 반응시킴으로써 합성된 지방족 공중합 폴리에스테르를 원료로 하여 T다이를 갖는 성형기 내에서 용융, 압출시킨 후 연신하는 것을 특징으로 하는 생분해성이 우수한 플랫얀의 제조방법으로 이 제조방법은 융점이 낮은 대신에 결정화도가 낮아져 성형가공 특성이 크게 개선되어 플랫얀으로서의 제조공정성 및 기계적 물성 개선의 효과를 기할 수 있는 잇점이 있다.An object of the present invention is to provide an aliphatic polyester flat yarn excellent in mechanical strength and elongation and excellent in biodegradability. The technical composition is composed of 97 to 99.9 mol% of succinic acid or its ester compound as an acid component, 0.1 to 3% , 70 to 97 mol% of one component selected from 1,4-butanediol or ethylene glycol as the diol component, 3 to 30 mol% of neopentyl glycol, Is subjected to esterification or transesterification and polycondensation reaction, and the resulting aliphatic copolymer polyester is melted and extruded in a molding machine having a T-die, followed by drawing. The flat yarn having excellent biodegradability As a production method, this production method has a lower melting point and a lower crystallization degree, It has the advantage that can talk to the effect of the resistance and improved mechanical properties.
