Abstract: [Problem] To provide: a spun yarn which has not only a soft texture but also functions that cannot be attained by a natural or cellulose-based fiber alone, namely high water absorption, quick drying property and non-see-through property, and which is suitable for clothing, particularly for inner shirts or sport shirts; and a woven or knitted fabric comprising the same. [Solution] A mixed spun yarn which comprises 20 to 80 mass% of a polyester-based fiber having a flat multi-lobe section and 20 to 80 mass% of a cellulose-based fiber, wherein: the cross section of the polyester-based fiber has a flat shape which has six or more protrusions on the circumference; and the flatness degree and modification degree of the cross section are prescribed.

Abstract: [Problem] 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. [Means of solution] The nonwoven fabric for sanitary materials according to the present invention is 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.
