Title:
ABSORBENT ARTICLE
Document Type and Number:
WIPO Patent Application WO/2014/050757
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an absorbent article that is unlikely to become sticky in the excretory orifice contact area of a top sheet after having absorbed menstrual blood, that has a silky feel, and that is unlikely to contaminate a production line and other absorbent articles. The absorbent article of the present invention has the configuration indicated below. The absorbent article (1) comprises a liquid-permeable top sheet (2), a liquid-impermeable back sheet (8), and an absorbent body (3) that is arranged between the top sheet (2) and the back sheet (8), and is characterized in that: the excretory orifice contact area of the liquid-permeable top sheet (2) has an area (7) containing a blood lubricity-imparting agent, said blood lubricity-imparting agent having a kinematic viscosity of 0.01-80 mm2/s at 40 °C, a water hold percentage of 0.01-4.0 mass%, and a weight average molecular weight of less than 1,000; and in that the amount of the blood lubricity-imparting agent on the clothing-side surface (11) of the top sheet (2) is greater than the amount of the blood lubricity-imparting agent on the skin-side surface (10) of the top sheet (2) at a location in the area (7) containing the blood lubricity-imparting agent where said surfaces overlap in the thickness direction of the absorbent article (1).
