Problems solved by technology

[0002] In sanitary napkins, menstrual blood passes through the liquid-permeable topsheet and is absorbed and retained by the absorbent body. However, because menstrual blood is highly viscous, it tends to remain on the topsheet.

Embodiment 3

[0155] The measurement was carried out 3 times, and the average value was taken.

[0156] The significance of the water retention rate of the blood lubricity imparting agent is as described later, if the water retention rate decreases, the affinity of the blood lubricity imparting agent and menstrual blood decreases, and it is difficult for the blood lubricity imparting agent to reach the skin contact surface of the top sheet. The tendency of the menstrual blood to move together into the absorbent body. On the other hand, if the water retention rate increases, like surfactants, the affinity with menstrual blood becomes very high, and the blood absorbed is likely to remain on the skin contact surface of the top sheet, thereby making the skin contact surface of the top sheet Tendency to color faces red.

[0157] The water retention rate tends to be as follows: a) the molecular weight of the blood lubricity imparting agent is smaller, and b) polar groups such as carbonyl bond (-...

Abstract

　The present invention provides an absorbent article in which liquid remaining on a top sheet can be reduced.　In an absorbent article (1) according to the present invention, a top sheet (2) is a non-woven fabric containing thermoplastic resin fibers subjected to hydrophilic treatment. An absorber (4) includes: an absorbent core (41) containing fluff pulp; a top-sheet-side cover sheet (42) joined to the top-sheet-side surface of the absorbent core (41) by an adhesive; and a back-sheet-side cover sheet (43) joined to the back-sheet-side surface of the absorbent core (41) by an adhesive. The top-sheet-side cover sheet (42) is a non-woven fabric containing thermoplastic resin fibers subjected to hydrophilic treatment. The back-sheet-side cover sheet (43) is an air-laid non-woven fabric containing hydrophilic fibers, is laminated to the back sheet (3) directly or with an adhesive layer therebetween. Through holes (5) are provided that extend from a surface region (20) of the top sheet (2) to the back-sheet-side surface of the back-sheet-side cover sheet (43).

Description

technical field [0001] The present invention relates to an absorbent article. Background technique [0002] In sanitary napkins, menstrual blood passes through the liquid-permeable top sheet and is absorbed and held by the absorbent body. However, since menstrual blood is highly viscous, it tends to remain on the top sheet. When menstrual blood remains on the top sheet, it gives the user a sticky feeling, visual discomfort, etc., and therefore, it is sought to reduce the menstrual blood remaining on the top sheet. As a means for this, for example, forming a through-hole in a top sheet (patent document 1) etc. are known. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: International Publication No. 2008 / 146541 Contents of the invention [0006] The problem to be solved by the invention [0007] However, in an absorbent article formed with through holes as in Patent Document 1, when a force (for example, wearer's body pressure) is appl...
