Problems solved by technology

[0005] However, in the anti-leakage side wall formed by the non-woven fabric mainly composed of hydrophobic synthetic fibers, since the fibers constituting the non-woven fabric have little liquid retention force, there is almost no capillary action between the fibers, so when a small amount of body fluid When sweat or sweat adheres to the surface of the leak-proof sidewall, it is difficult to move it
Therefore, the above-mentioned small amount of body fluid tends to remain between the skin and the leak-proof side wall, and the user tends to feel wet
[0006] In addition, the above-mentioned leak-proof side wall formed with plastic cloth, the surface of the leak-proof side wall is likely to be in close contact with the skin, therefore, the above-mentioned small amount of body fluid or sweat is likely to remain between the skin and the surface of the leak-proof side wall, and as a result, the leak-proof side wall The surface of the side wall sticks to the skin, causing discomfort to the user
In addition, the leak-proof side wall formed by plastic cloth has poor air permeability and feels stuffy

Abstract

In conventional sanitary napkins, a small amount of liquid or sweat tends to remain on the leak-proof side wall, and the user feels wet. In the absorbent article of the present invention, the non-woven fabric sheet (6) forming the leak-proof side wall (5) of the sanitary napkin is formed of hydrophobic synthetic fibers (11) with a fiber length of 38 to 64 mm, and dispersed therein An aggregate (12) of hydrophilic fibers such as cotton with a fiber length of 5 to 25 mm, the aggregate (12) is in the shape of a block or crimp. A small amount of liquid on the surface of the anti-leakage side wall (5) is kept by the assembly (12) of hydrophilic fibers. Therefore, it is easy to keep the surface of the anti-leakage side wall (5) in a dry state, reducing the wet feeling on the surface of the anti-leakage side wall (5), and the user has no discomfort.

Description

technical field [0001] The present invention relates to an absorbent article that absorbs and retains excreta such as menstrual blood, and particularly relates to an absorbent article that reduces the moist feeling between the leak-proof side wall and the skin and does not give discomfort to the user. Background technique [0002] Conventionally, absorbent articles such as various sanitary napkins, urine pads, and disposable diapers have been developed. These absorbent articles have an absorbent layer between a liquid-impermeable inner layer and a liquid-permeable surface layer, and have leak-proof side walls extending in the longitudinal direction on both sides of the absorbent layer. [0003] The above-mentioned leak-proof side wall is formed of a non-woven fabric mainly composed of hydrophobic synthetic fibers. The above-mentioned leak-proof side wall formed of the hydrophobic synthetic fiber nonwoven fabric has a small liquid holding capacity of the fiber itself. There...
