The present invention relates to a perforated nonwoven fabric and a method for producing the same, and more particularly, to complete the three-dimensional funnel-type openings of the two-layer open nonwoven fabric by fitting and overlapping each other, the first layer open nonwoven fabric is provided with a projection and a recessed portion The projection part has an inner space, and the three-dimensional funnel-shaped opening formed in such a manner that the upper layer of the second layer opening nonwoven fabric and the lower layer of the recessed portion of the first layer opening nonwoven fabric are bonded to each other and overlapped with each other is formed in the first layer opening. It penetrates the nonwoven fabric and the second layer opening nonwoven fabric, and a gas flow passage is formed between the inner continuous space of the first layer opening nonwoven fabric portion and the second layer opening nonwoven fabric, and provides an osmotic passage for the osmotic effect of the nonwoven fabric. Furthermore, the air flow to prevent foreign substances such as liquids, excreta, diarrhea, etc. to osmosis more quickly and leave no residue By providing the inner and outer loops as possible, the damp and stuffy feeling was reduced, and the first layer opening nonwoven fabric was firmly fixed on the extruder roller by using a process of drilling using a needle during the process, thereby making the two layers of nonwoven fabric in the overlapping process. In addition to preventing the wrong location, the manufacturing process can be further simplified, thereby reducing the manufacturing cost.본 발명은 구멍 뚫린 부직포 및 그 생산 방법에 관한 것으로서, 더욱 자세하게는 두 층 개공부직포의 입체 깔때기형 개공을 서로 끼워 맞춰 겹치는 방식으로 완성하는 것이며, 제1층 개공부직포는 돌기부분과 요입부분을 갖추고 있고, 돌기부분은 내부 공간을 갖추고 있으며, 제2층 개공부직포의 상측과 제1층 개공부직포의 요입부분의 하층을 서로 접착 결합하고, 끼워 맞춰 겹치는 방식으로 형성된 입체 깔때기형 개공은 제1층 개공부직포와 제2층 개공부직포를 관통하게 되며, 제1층 개공부직포돌기부분의 내부 연속 공간과 제2층 개공부직포 사이에는 기체가 흐르는 통로가 형성되며, 부직포의 삼투 효과를 위해 삼투 통로를 제공하며 더 나아가 액체, 배설물, 설사 등과 같은 이물질이
