Abstract

본 발명은 바람직한 태양에서 제1표면 또는 착용자-접촉 표면, 및 제2표면 또는 가멘트-대향 표면을 포함하는 유체투과성 웹에 관한 것이다. 웹은 특히 일회용 흡수제품의 상면시이트로서 사용하기에 매우 적합하다. 제1표면과 제2표면은 중간부에 의해 서로 분리되어 있다. 웹의 제1표면은 중간부의 표면 에너지 보다 낮은 표면 에너지를 나타내는 구조를 제공한다. 바람직한 태양에서, 웹은 표면 에너지 구배를 정하는 비교적 낮은 표면 에너지를 갖는 다수의 영역을 가지며, 이 때 이들은 더 높은 표면 에너지의 웹 표면과 계면을 이룬다. 더 구체적으로, 본 발명은 유체를 제 1표면 또는 착용자-접촉 표면으로부터 효과적으로 이동시키기 위해 배향 및 위치된 다수의 소규모의 표면 에너지 구배를 갖는 유체투과성 웹에 관한 것이다. 웹은 본질적으로 원하는 표면 에너지 특성을 얻으면서도 기재 물질의 육안, 감촉 및 물리적 특성을 보유한다. 본 발명에 따른 유체 전달 웹은 바람직하게는 제 1표면상에 소규모의 표면 에너지 구배를 정하는 불연속적인 이격된 영역을 포함하여 개구 또는 모세관 도입부를 향한 소규모의 유체 이동을 도움으로써 제 1 표면으로부터 유체를 전달 시킨다. 이러한 웹은 또한 바람직하게는 모세관 구조물내에서 제 1 표면에 수직인 소규모의 표면 에너지 구배를 포함하여, 모세관 유체 전달을 위해 제 1 표면으로부터 모세관내로의 유체의 이동을 돕는다. 본 발명에 사용하기에 적합한 웹 물질로는 천공성형된 필름, 천공 및 비천공된 부직물, 복합 구조물 등이 있다.
