접합 단계에서 부직포를 열융착시키는 압착 롤러(300)는 130도 이상으로 가열되어야 제2 부직포 원단(20)을 부분 용융시킬 수 있으며, 과도한 온도로 용융시키는 경우 압착 롤러(300) 외주면에 제2 부직포 원단(20)이 붙는 현상이 발생될 수 있다.The
이러한 접합 단계를 거친 소재는 접착제를 이용하여 다층으로 접합시키는 적층 단계와, 상기 접착 단계를 거친 소재를 일정한 크기로 절단시켜서 필터 형태로 제단하는 절단 단계를 거쳐서 최종 필터로 제조된다.The material that has undergone the bonding step is manufactured as a final filter through a laminating step of laminating the laminating material to a multilayer using an adhesive and a cutting step of cutting the laminating material into a filter shape.

도 3은 본 발명의 바람직한 다른 일실시예에 따른 부직포 필터의 제조방법을 도시하는 개념도이다.3 is a conceptual diagram showing a method of manufacturing a nonwoven filter according to another preferred embodiment of the present invention.
도 3에 도시된 바와 같이 예열 단계는 상부의 절곡 롤러(200a) 내부에 열매체유 또는 물을 가열시키서 일정한 온도 이상으로 가열시키고, 제1 부직포 원단(10)을 예열 시킴과 동시에 하부의 절곡 롤러(200b) 사이로 통과시켜서 주름을 형성시키는 방식으로 공정을 간소화시킬 수 있다.이러한 하부 절곡 롤러(200b)의 하측에는 압착 롤러(300)를 접촉시켜서 제2 부직포 원단과 열융착시키는 방식을 이용하면 보다 빠르게 열융착 과정을 수행할 수 있다.As shown in FIG. 3, in the preheating step, the heat medium oil or water is heated to a predetermined temperature or higher in the
도 4는 본 발명의 바람직한 다른 일실시예에 따른 부직포 필터의 제조방법에 의해서 제조된 부직포 필터의 단면도이다.4 is a cross-sectional view of a nonwoven filter fabricated by a method of manufacturing a nonwoven filter according to another preferred embodiment of the present invention.
도 4에 도시된 바와 같이 제1 부직포 원단(10)과 제2 부직포 원단(20)은 열융착에 의해서 접합되고, 이를 적층시키면 부직포 필터가 완성된다.(물론, 절단 단계를 거쳐야 한다.)As shown in FIG. 4, the first
이 과정에서 제1 부직포 원단의 산 부위에 접합되는 다른 제2 부직포 원단만 접착제를 이용하여 접합시키므로 종래의 부직포 필터의 제조 방법과 비교하여 접착제의 사용을 현저히 저감시킬 수 있게 된다.In this process, only the second nonwoven fabric bonded to the acid portion of the first nonwoven fabric is bonded using an adhesive, so that the use of the adhesive can be remarkably reduced as compared with the conventional method of manufacturing the nonwoven filter.
이상과 같이 본 발명은 부직포 필터의 제조방법을 제공하는 것을 주요한 기술적 사상으로 하고 있으며, 도면을 참고하여 상술한 실시 예는 단지 하나의 실시 예에 불과하므로 본 발명의 진정한 범위는 특허청구범위에 의해 결정되어야 한다.As described above, the present invention provides a method of manufacturing a nonwoven filter, and it is a principal technical idea of the present invention to provide a nonwoven filter.
