Abstract

A topsheet of an absorbent article having a laminated nonwoven fabric composed of an upper layer (21) disposed on the skin side and a lower layer (22) disposed on the absorbent member side. The nonwoven fabric has a large number of sheet compressed parts (23) formed by compression joining the upper layer (21) and the lower layer (22) and a large number of lower layer compressed parts (24) positioned between the sheet compressed parts (23) and formed by compressing the lower layer (22). The minimum density of the substantially non-compressed area (29) of the lower layer (22) is equal to or higher than that of the substantially non-compressed area 28 of the upper layer (21).

Description

[0001] This application is a divisional application with the filing date of September 20, 2004, the application number of 200410079823.4, and the title of the invention "surface sheets and absorbent articles for absorbent articles". technical field [0002] The present invention relates to absorbent articles such as sanitary napkins, sanitary pads, incontinence pads, and disposable diapers, and topsheets suitable for their skin-contacting surfaces. Background technique [0003] For topsheets of absorbent articles such as sanitary napkins and disposable diapers, it is required to smoothly transfer body excrements such as menstrual blood and urine to the absorbent body. [0004] As a top sheet of an absorbent article, a top sheet made of a nonwoven fabric having an upper layer arranged on the skin side and a lower layer arranged on the absorber side has been proposed. The small gap improves the transferability of liquid from the upper layer to the lower layer (see JP-A-7-17813...
