【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、生理用ナプキン、ベツド用パッド。[Detailed description of the invention] [Industrial application field] The present invention relates to sanitary napkins and bed pads.

る。[Prior Art] The characteristics required for this type of absorbent article are: 1) It can quickly absorb and disperse body fluids discharged from the wearer's body, and - The body fluids once absorbed can flow back from the absorbent article. In addition, it should be able to withstand the wearer's vigorous movements and maintain its strength even when wet. Conventionally, commonly used diapers use a liquid-permeable sheet such as a thick non-woven fabric sheet as the surface sheet, which ensures absorption of body fluids and prevents strength deterioration due to use. Ta. However, in order to reduce costs and prevent loose stools, it has recently been proposed to use a liquid permeable sheet having a large number of holes as the top sheet.

シートから構成されたものが提案されている。For example, ■Japanese Patent Publication No. 57-17081 discloses a structure consisting of a top sheet made of liquid-permeable polyethylene, an absorbent body, and a back sheet, in which a large number of tapered capillaries are provided on the top sheet. Showa 62-12500
In Publication No. 1, the product was composed of a porous top sheet made of hydrophobic fibers, a single cushion fiber layer to improve fit to the wearer and backflow prevention, an absorbent material, and a water-impermeable back sheet. something is proposed.
［発明が解決しようとする課題］ しかしながら、従来技術には次に示す欠陥がある。[Problem to be solved by the invention] However, the prior art has the following deficiencies.
上記技術■の場合；液体不透過性シートに先細毛細管を
設けたとしても、その管の先端に線条パルプを主体とす
る吸収体が直接接触しているため、体液の瞬間的な吸収
力が弱く、このため吸収体内部に浸透するよりも先に表
面シートを伝って漏れが発生することが多い。In the case of the above technology (■): Even if a tapered capillary tube is provided in the liquid-impermeable sheet, the absorbent material mainly made of striated pulp is in direct contact with the tip of the tube, so the instantaneous absorption capacity of body fluids is reduced. It is weak, and as a result, leakage often occurs through the topsheet before penetrating into the absorbent body.

が困難である。In the case of the above technology (■): Since both the top sheet and the cushion fiber layer are composed of hydrophobic fibers, the adhesion between the two is low, and the top sheet may stick to the wearer's skin or sway during use. do. As a result, a gap is created between the top sheet, the cushion fiber layer, and the absorbent body, which impedes absorption.Furthermore, if the cushion fiber layer is a single layer with a uniform denier number in the thickness direction, 12 denier r
If you select a material with a small denier number to increase absorbency when y > a pronation, the cushion fiber layer tends to lose its shape and become wavy or lumpy during use. Therefore, if a material with a large denier number is selected, the liquid absorbency will be inhibited, and in the end, it will be difficult to achieve both of the above characteristics at the same time.
そこで本発明の主たる目的は、体液の逆戻り防止効果が
高く、型くずれやヨレがなく形状安定性に優れ、もって
逆戻り防止効果の低下のない吸収性物品を提供すること
にある。Therefore, the main object of the present invention is to provide an absorbent article that has a high effect of preventing body fluids from returning, has excellent shape stability without deformation or twisting, and does not have a decrease in the effect of preventing body fluids from returning.

An absorbent article having an m layer and an absorbent body mainly made of cotton-like pulp, wherein the upper surface of the cushion m delamination layer directly faces the liquid permeable topsheet, and the cushion am layer is made of fibers of 14 denier or less. The fibers are substantially integrated, and the fibers constituting the top layer have a denier of 4 to 8, and the layers below are comprised of uA male fibers that exceed the denier of the top layer. It is something to do.

に浸透される。[Function] In the present invention, since the surface sheet is a liquid-permeable material that is substantially liquid-impermeable in itself and has desired openings and their arrangement, internal absorption is prevented during use. Even if pressure is applied to the body element, back movement through small openings and from parts of the base material other than the openings is prevented. On the other hand, the liquid discharged onto the top sheet permeates into the interior through the small number of pores.
この浸透された液は、クッション繊維層に吸収される。This permeated liquid is absorbed into the cushion fiber layer.
このクッション繊維層は、疎水性繊維からなるので浸透

化することで型くずれを防止できる。At this time, it is important to use fibers with a small denier number in order to increase the liquid absorption rate, and for this purpose, the method described in Book 9.
In Akira, 4 to 8 deniers are used. However,
This has poor shape stability and tends to lose its shape during use. Therefore, according to the present invention, a lower layer having a greater resonyl loss than the uppermost layer is formed, and this is integrated with the uppermost layer, thereby preventing deformation.

い。In the present invention, the liquid-permeable surface sheet 3 has a large number of holes with a hole diameter dO of 5 to 2 mm and an interval of 0.5 to 2 mm, not on the entire surface but preferably in a region less than 100 mm in the center in the longitudinal direction. 3a, 3a, . This is because it is easy to occur, and 100
If the diameter of the hole is less than 2 mm and the surrounding area is left unopened, tearing will be less likely to occur, and if the pore diameter of the open hole is less than 0.5 mm and the pore spacing is more than 2 mm, it will be difficult for body fluids to penetrate. on the other hand,
If the pore diameter exceeds 2 mm and the pore spacing is less than 0.5 mm, the strength of the top sheet decreases and reversion tends to occur. In this case, the diameter of the pore is preferably 0.5 to 2 layers at its narrowest point.The shape of the pore is preferably circular or close to it.Especially the elliptical shape is the body fluid that is circular due to surface tension. On the other hand, it is superior in terms of the absorption effect inside the interior body. Further, as shown in FIG. 3, the opening 3a may have a conical burr 3b, the surface weight of the top sheet is 10~ia g7rrr, and the weight of the cushion fiber layer is 15~40g/rr1. ' is preferable, and the apparent density of the lam layer is preferably 0.005 to 0.05 g/cm''.

を絡み合わせることなどによってもよい。If the above-mentioned cushion fiber layer is made of one layer and made of the same type of fiber, if the denier number is 4 to 8, the permeation rate of body fluids is fast, but the cushion fiber layer lacks shape stability.
If it is a single layer with a denier number of 8 to 14, the shape stability is good, but the permeation rate of body fluids from the top sheet decreases, and body fluids tend to form on the surface of the top sheet. Residues are more likely to form, and the fibers themselves become stiffer, resulting in poor texture. Therefore, after examining the cushion fiber layer from various angles, we found that the optimal cushion fiber layer configuration is 4 to 8
A hydrophobic synthetic fiber layer with a denier of 14 denier or less and a denier smaller than the top cushion layer, preferably 8 to 14 denier, is provided on the lower surface of the layer, and these two layers are integrated by heat fusion. It was found that a modified version is desirable. Further, as a means for integrating the upper and lower cushion layers, in addition to heat fusion, intertwining of fibers at the interface bonded with an adhesive may be used.

Therefore, it is preferable to apply the adhesive to each other by spraying.The state of application of this adhesive is indicated by 9, and 10 indicates that the shoe 94 extends 1m into the male layer due to leakage from the front and back. It is a leak-proof sheet.
