摘要：
The present invention aims to provide nonwoven fabric for sanitary materials having high water absorbability and high diffusing capacity for liquids such as water and chemicals as well as high bulkiness, flexibility, and anti-see-through property, and also provides sanitary material products produced therefrom including a water absorbing sheet for sanitary napkins. The nonwoven fabric for sanitary materials may comprise nonwoven fabric of polyester based fiber with a flattened multilobar cross section containing 6 or more convex portions along the cross-sectional circumference, the polyester based fiber with a flattened multilobar cross section having a flatness of 2.0 to 3.0, a degree of irregularity of 1.0 to 5.0, and a convex ratio of 0.6 to 0.9, and the polyester based fiber with a flattened multilobar cross section being joined by heat-weldable fiber.
