Abstract: 접착력이 우수하고 탈 부착시 소음발생이 적을 뿐만 아니라, 구조가 간단하여 대량생산이 용이한 건식접착 체결시스템 및 이의 사용방법이 개시되어 있다. 이를 위하여 제1 기판 상에 형성된 제1 미세섬모를 가지는 제1 접착부재와 상기 제1 미세섬모와 접촉하여 접착력을 나타내도록 제2 기판 상에 형성된 제2 미세섬모를 가지는 제2 접착부재를 포함하는 건식접착 체결시스템 및 이의 사용방법이 제공된다. 기존의 벨크로 체결 시스템과 달리 결합을 위한 후크부 및 루프부가 구분지어지지 않아 생산효율과 실효성의 향상을 기대할 수 있다는 이점이 있다. 또한 결합 및 분리 과정에서 소음이 발생하지 않을 뿐만 아니라, 마이크로 또는 나노 사이즈의 미세 섬모를 이용하기 때문에 매우 좁은 면적에서도 접착력을 구현할 수 있다.

Abstract: Provided are a dry adhesive fastening system which has a relatively superior adhesion, does not almost generate noises during the attaching or detaching operation, has a simplified structure adapted to mass production requirements, and a method of using the same. For this, the dry adhesive fastening system includes a first adhesion member having a first microvillus disposed on a first board and a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion. Also, unlike the existing velcro fastening system, the hook and loop may not be classified to improve production yield and effectiveness. Also, during the attachment/detachment, the noises may do not occur. In addition, since the microvillus having the micro or nano size is used, the adhesion may be realized even though a very small area is provided. Therefore, the dry adhesive fastening system according to the embodiment of the present invention may be applied in fields greater than those of the existing velcro fastening system.
