    • 본 발명에서는 흡습성 섬유로 이루어진 부직포 원단 및 상기 원단의 일면 또는 양면에 합지된 발수성 부직포로 구성된 적층형 부직포로서, 상기 발수성 부직포가, 비흡습성 섬유로 이루어진 부직포 원단을 함불소분자 가스 하에서 플라즈마 처리하여, 부직포 표면의 섬유에 불소 코팅이 형성된 것임을 특징으로 하는 흡습-발수성 부직포 적층체를 제공한다. 본 발명에 따르는 흡습-발수성 부직포 적층체는 흡습성 섬유가 가지는 본연의 흡습성을 유지하면서도 흡습-건조의 반복에 따르는 흡습성 섬유의 수축을 줄일 수 있다. 또한 본 발명에 따르는 흡습-발수성 부직포 적층체는 그 표면에 불소코팅이 이루어짐으로써 부직포의 표면이 발수성능을 가지게 되어 부직표 표면의 수접촉각이 상승한다. 그 결과, 흡습성 섬유가 가지는 흡습성을 그대로 유지하면서도 흡습성 원단의 흡습속도를 지연시킬 수 있다. 흡습속도의 지연은 흡습-발수성 부직포 적층체의 표면에 다량의 물이 직접 접촉하는 경우 흡습속도를 지연시켜, 예를 들어, 표면에 물방울 상태로 맺혀있는 수분을 털어내 버릴 수 있다는 실용적인 이점이 있다.
