Problems solved by technology

[0007] On the other hand, for the leucorrhea absorbent sheet as a thin absorbent article, the absorbent layer described in the aforementioned publication is made of a thin article, covered with a surface layer, and when recesses are formed from the surface layer to the absorbent body, the absorbent body Thin and the concave part itself is also shallow, so the aforementioned concave part is more likely to be damaged than the aforementioned menstrual napkin due to body pressure when wet
In addition, because the leucorrhea secreted by women is more viscous than menstrual blood, if the concave part is damaged, it is difficult for the high-viscosity body fluid to be introduced from the surface layer into the absorbent layer

Embodiment 1

[0120] Two sheets of the air-laid nonwoven fabric of Comparative Example 3 were overlapped and used.

Embodiment 2

[0122] The air-laid non-woven fabric contains chemical pulp (fiber length 5mm) and the composite thermoplastic resin fiber (3.3dtex, fiber length 5mm) that the sleeve is PE and the core is PET in a mass ratio of 70:30. The total mass of the fiber aggregate was 10% by mass of an acrylic adhesive, which was sprayed on both surfaces.

[0123] Only one sheet of the aforementioned airlaid nonwoven was used as the absorbent layer. Basis weight (head payment) is 40g / m 2 , the density is 0.035g / cm 3 .

Embodiment 3

[0125] The air-laid non-woven fabric contains chemical pulp (fiber length 5mm) and the composite thermoplastic resin fiber (3.3dtex, fiber length 5mm) that the sleeve is PE and the core is PET in a mass ratio of 70:30. The total mass of the fiber aggregate was 10% by mass of an acrylic adhesive, which was sprayed on both surfaces.

[0126] Only one sheet of the aforementioned airlaid nonwoven was used as the absorbent layer. Basis weight (head payment) is 60g / m 2 , density is 0.053g / cm 3 .

Abstract

In a conventional thin absorbent article, recesses formed from a top layer to an absorbent layer are easily compressed when the absorbent article is compressed by a body weight in a wet state. To solve the problem, a top layer 5 is formed of two sheets of air-through non-woven clothes 5a, 5b. An absorbent layer 4 comprises hydrophilic fibers and hot-melt synthetic fibers. With hot meltability of the synthetic fibres, the hot-melt synthetic fibers and the hydrophilic fibers are combined together to form a high wet strength. Thus, in a wet state and under a body weight, the recesses are not easy to be compressed so that liquid can be absorbed into the absorbent layer from the recesses.

Description

technical field [0001] The present invention relates to an absorbent article called a panty liner, which is a thin article used as a leucorrhea absorbent sheet, especially an absorbent article that easily absorbs highly viscous body fluids into the absorbent layer and provides a good wearing feeling on the skin Sexual articles and methods of manufacture. Background technique [0002] As a thin absorbent article, there is a leucorrhea absorbent sheet called a panty liner. The absorbent sheet is used by fixing the inside of the crotch of the panty through a pressure-sensitive adhesive layer. The general structure of absorbent articles is to provide a liquid-absorbing absorbent layer under a liquid-permeable surface layer, and body fluids flowing to the surface layer are drawn in by capillary action of the absorbent layer. [0003] However, since the aforementioned leucorrhea absorbent sheet is used to absorb high-viscosity body fluids secreted by women's vaginas, if the afor...
