Problems solved by technology

[0007] Forming the above-mentioned striped resin layer can reduce the contact area with the skin, but because the surface is still a resin film, it is difficult to follow the movement of the skin, and it is difficult to be completely non-irritating to the skin
In addition, when the above-mentioned thin non-woven fabric is overlapped, the contact with the skin is soft, but due to the capillary action of the fibers constituting the non-woven fabric, the liquid tends to stay in the non-woven fabric, giving the skin a moist feeling.

Abstract

An absorptive article which effectively utilizes the advantage of a perforated film, softens the contact with the skin and hardly stagnates fluid. The absorptive article is provided with a surface layer 10 on the surface of an absorptive core. The surface layer 10 is formed by joining belt-like fiber layers 12 formed of continuous filaments, etc. to the perforated film 11 by spaced joint lines. The Loops 14a and 14b are formed by the fiber layers 12 between the joint lines when the perforated film 11 is shrunk. Loops 14a and 14b follow up the movement of the skin to eliminate the feel of stimuli and rapidly introduce the fluid to the perforated film 11.

Description

technical field [0001] The present invention relates to an absorbent article having a surface layer composed of a combination of an apertured film and a fibrous layer, which provides a good feel to the wearer. Background technique [0002] Absorbent articles such as sanitary napkins and disposable diapers generally have a structure in which a liquid-impermeable back sheet is superposed on the back side of an absorbent layer, and a liquid-permeable top sheet is superimposed on a liquid-receiving surface side. [0003] As the surface material of the aforementioned absorbent article, it is produced from an apertured film sheet of synthetic resin formed with a plurality of apertures. The plurality of openings in the apertured film sheet have the function of liquid-permeable passages or liquid-permeable channels, and the liquid given to the surface of the sheet penetrates into the absorbent layer through the aforementioned apertures. [0004] Unlike the non-woven fabric of fiber...
