The present invention relates to a heteromorphic section polyester staple fiber filtering material having excellent filtering performance and a method for manufacturing the same. The heteromorphic section polyester staple fiber filtering material having excellent filtering performance according to the present invention comprises the steps of: manufacturing heteromorphic section yarn by spinning a polyester polymer having a single yarn denier less than 0.5 via a spinning nozzle with two or more bent curved surfaces having a heteromorphic level ranging from 0.5 to 1.5; manufacturing 3.0-5.0 mm short-cut stable yarn by using elongated, entangled and wound filament yarn; and fabricating a filter by passing the short-cut stable yarn through a composition step, a paper step, a processing step, and a slitter step. In accordance with the heteromorphic section polyester staple fiber filtering material having excellent filtering performance and the method for manufacturing the same according to the present invention, a process of manufacturing heteromorphic section filament yarn is simplified, and operation efficiency is excellent. Furthermore, a rate of change in section is low and evenness of yarn is excellent, and thus excellent dust collection efficiency is achieved due to an increase in a contact surface during manufacture of the filter. Moreover, short-cut distribution is excellent, and thus an improved filter function is provided.

    본 발명은 필터 성능이 우수한 이형단면 폴리에스터 스테이플 섬유 여과제 및 그 제조방법에 대한 것으로, 상기한 본 발명의 필터 성능이 우수한 이형단면 폴리에스터 스테이플 섬유 여과제의 제조방법은 이형도가 0.5 내지 1.5의 굴곡 곡면 2개 이상을 가지는 방사노즐에서 단사섬도가 0.5데니어 미만으로 폴리에스터 중합체를 방사하여 이형단면사를 제조하고, 연신, 교락하여 권취한 필라멘트사로 하여 3.0 내지 5.0mm 숏컷 스테이플 사를 제조한 후 조성공정, 초지공정, 가공공정, 슬리터 공정을 거쳐 필터로 제조함을 특징으로 한다. 상기와 같이 구성되는 본 발명의 필터 성능이 우수한 이형단면 폴리에스터 스테이플 섬유 여과제 및 그 제조방법은 이형단면 필라멘트사를 제조함에 있어 생산공정이 간단하고 조업성이 우수하며, 단면 변동률이 적고 균제도가 우수하여 필터 제조 시 접촉면이 증가하여 먼지를 포집하는 효율이 우수하며, 숏컷이 분산성이 우수하여 향상된 필터기능을 제공하여 상기한 종래의 문제점을 해결하였다.
