Absorbent article

摘要

The present invention addresses the problem of providing an absorbent article that has an improved ability to transfer menstrual blood from a liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer. To solve this problem, provided is a sanitary napkin provided with a top sheet, a back sheet and an absorbent body that is interposed between the top sheet and the back sheet, wherein convex portions formed in an excretion orifice contact region of the top sheet are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000.

1. An absorbent article comprising a liquid-permeable layer, a liquid-impermeable layer and an absorbent body situated between the liquid-permeable layer and the liquid-impermeable layer,
wherein the liquid-permeable layer has a first layer with a skin contact surface and a non-skin contact surface, the first layer is a layer formed by heat stretching of a heat-extendable fiber layer that has been partially compressed by compressed sections, a projection bulges out on the skin contact surface by heat stretching of the heat-extendable fiber layer at least in the excretory opening contact region of the skin contact surface, and at least the projection of the excretory opening contact region are coated with a blood slipping agent having a 40° C. kinematic viscosity of 0.01 to 80 mm2/s, a water holding percentage of 0.01 to 4.0 mass % and a weight-average molecular weight of less than 1,000.
