Abstract

Заявленный проницаемый для жидкости нетканый материал дает возможность жидкости организма проникать в материал локально, без растекания по поверхности. Нетканый материал включает 100-30 масс. % основных многокомпонентных волокон со структурой "сердцевина в оболочке". Каждое волокно состоит из сердцевины из смолы с высокой температурой плавления и оболочки из смолы с низкой температурой плавления. На поверхности разреза, параллельной машинному направлению нетканого материала, эти основные многокомпонентные волокна проходят в машинном направлении, при этом являются свитыми в направлении толщины нетканого материала. На поверхности разреза, параллельной поперечному направлению, многокомпонентные волокна проходят в направлении толщины и имеют средний угол волокна 75° или меньше. Основные многокомпонентные волокна, которые пересекаются друг с другом, сплавлены друг с другом в результате плавления оболочки, выполненной из смолы с низкой температурой плавления.
