Problems solved by technology

[0004] However, in the structure of the sanitary pad described in JP-A-11-28222, the absorbed bodily fluid cannot penetrate the middle layer sheet and cannot reach the back sheet, so the speed at which the body fluid becomes water vapor and evaporates from the back sheet cannot be adjusted. saying is enough
Therefore, although the wet and sticky feeling caused by the direct contact of the wearer's skin with body fluids can be improved, the airtight feeling caused by the water vapor generated by the heating of the absorbent article due to body temperature is still easy to occur, and it is difficult to last when worn for a long time. stay dry

Embodiment Construction

[0024] Hereinafter, based on one preferred embodiment (first embodiment), the absorbent article of the present invention will be described with reference to the drawings.

[0025] The sanitary pad 1 of the first embodiment of the absorbent article of the present invention is shown in Fig. 1(a), Fig. 1(b) and Fig. Moisture leak-proof layer 3 constitutes. The liquid-permeable layer 2 has its bottom surface 22 facing the leak-proof layer 3 and is bonded to the leak-proof layer 3 by an adhesive (not shown). The layer 42 of the liquid-permeable layer 2 facing the leak-proof layer 3 has a denser fiber density than the layer 41 that contacts the skin.

[0026] The pantiliner 1 of this embodiment will be described in more detail below. The sanitary pad 1 of this embodiment is shown in Fig. 1 (a), Fig. 1 (b) and Fig. 2, only by the liquid-permeable layer 2 that forms with multi-layer fiber assembly, the leak-proof layer 3 of moisture permeability and An adhesive (not shown) that hol...

Abstract

This absorbent article comprises a liquid-permeable layer 2 formed of a plurality of layers of fiber assemblies and a leakproof layer 3 with moisture permeability, the liquid-permeable layer 2 is stuck to the leakproof layer 3 via adhesive with its bottom face 22 facing the leakproof layer 3, and the plurality of layers of liquid-permeable layer 2 is so formed that the fiber density of the layer 42 facing the leakproof layer 3 is denser than that of the layer 41 abutting on the skin.

Description

technical field [0001] The present invention relates to absorbent articles such as panty liners, underarm pads, nursing pads, and incontinence pads. Background technique [0002] In recent years, the wearing time of absorbent articles such as sanitary pads (sheets for vaginal discharge) and armpit pads has been extended to about half a day due to the increase in the employment rate of women and the increase in time spent outside. Compared to ensuring a large absorption capacity so that a large amount of bodily fluids do not leak to the outside, a particularly important function of these products is to keep them dry even if they are worn for a long time without being stuffy or damp or sticky. Sensation (dry feeling). [0003] Japanese Patent Application Laid-Open No. 11-28222 describes a sanitary pad in which a liquid-proof and breathable pad is inserted between a front sheet with through holes and a back sheet with air permeability. Sexual middle layer sheet. According to...
