Abstract
본 발명의 비대칭 다공성 시트는 밀도가 다른 2종이상의 부직포로 이루어진 합지부직포상에, 불소수지 함유 코팅액이 코팅 또는 함침되어, 필터수명, 통풍성 및 포집효율이 우수하다. 또한, 본 발명은 밀도가 다른 2종이상의 부직포를 열압연을 통해 합지한 후 소수성이 우수하고 용해성이 높은 불소수지로 코팅, 건조하는 것으로서, 비대칭 기공분포 및 비대칭 밀도구배를 갖도록 다층구조로 배치된 비대칭 다공성 시트를 연속생산이 가능하고 제조공정이 간단한 제조방법에 의해 제공할 수 있다. 나아가, 본 발명의 비대칭 다공성 시트는 우수한 필터수명, 통풍성, 포집효율 및 탈진효율을 가지며, 특히 시트 표면이 소수성으로 구성되어 반복사용이 가능하므로 공기중의 미세먼지, 입자 등을 제거하기 위한 공조용 에어필터로 유용하다.
