Embodiment Construction

[0024] The present invention relates to a top sheet and an absorbent article using the same. The top sheet can smoothly guide the liquid supplied to the top sheet into the absorbent body, and can effectively prevent discomfort or air tightness caused by liquid remaining on the surface, and Seepage caused by liquid flowing on the surface, etc.

[0025] Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings.

[0026] figure 1 with figure 2 The sanitary napkin 1 shown is an embodiment of the absorbent article of the second and third inventions, comprising a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and The liquid-retentive absorbent body 4 between them is formed to be substantially vertically long. The top sheet 2 is one embodiment of the top sheet of the absorbent article of the first invention.

[0027] The top sheet 2 has a size larger than that of the absorber 4 , and its longitudinal ...

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 a region 29 other than the sheet compressed parts 23 and the lower layer compressed parts 24 on the lower layer 22 is at least the minimum density of a region 28 other than the sheet compressed parts 23 on the upper layer 21.

Description

technical field [0001] 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 [0002] 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. [0003] 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-7-178133). [0004] However, the levels of leak-proof performance and absorbency required for products (absorbent articles) are increasing year by year, and there are cases where the above-mentioned requirements cannot be fully satisfied due...
