本発明は、産褥パッド、おむつ、生理用ナプキン等の衛
生用品、特にその外部に設けられる透液性外装材に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to sanitary products such as puerperal pads, diapers, and sanitary napkins, and particularly to a liquid-permeable exterior material provided on the outside thereof.
従来一般に、この種衛生用品の透液性外装材としては、

ート状物が用いられている。Conventionally, liquid-permeable exterior materials for this type of sanitary products are:
Sheet materials such as synthetic paper made of pulp, cotton, chemical fibers, etc., and nonwoven fabrics are used.

いては、全体的に弾性が乏しくていわゆる腰が弱い。This sheet-like material itself does not have satisfactory elasticity, but in order to use the sheet-like material as the exterior material and to reduce the bulk when worn and absorbed, it can be used as a liquid-absorbing component. Sanitary products that are made ultra-thin using materials such as so-called crepe water-absorbing paper with a reduced crepe application rate, compressed pulverized pulp (floss-like), and water-insoluble water-absorbing and swelling polymers have poor overall elasticity, resulting in the so-called stiffness. is weak.

The main object of the present invention is to provide a sanitary product which makes it possible to eliminate the above-mentioned disadvantages at once by using a fiber-embedded foam as the exterior material, and to achieve this object. The configuration will be described below based on the illustrated embodiment. As shown in FIGS. 1 and 2, the fiber-embedded foam 1, which is the exterior material of the present invention, preferably includes a flexible foam sheet 2 having open cells and a fiber length of 100 Wt.

Further, the fiber-embedded foam 1 can be easily manufactured, for example, by the following method.

、着用時によじれるようなことがなく、既述した従来の
衛生用品の欠点を一挙に解消することが可能である。That is, the required hardness, preferably JIS-K63Ol
A wide flexible elastic foam sheet 2 is placed on a non-porous support with a hardness of 50 or more, and a web made of fiber groups 3 having approximately the same width is placed on top of the sheet, and a jet pressure is applied from above the web. 15k9/c! i or more, a high-pressure liquid consisting of atomized liquid, etc., which is sprayed in the form of particles from a fine liquid spray nozzle ejected from a small orifice, alone or in combination, is sprayed onto the web and sheet. In this way, due to both the jetting of the high-pressure liquid from above and the reflection of the high-pressure liquid that collided with the support surface, the fiber group 3 remains almost uniformly distributed on the sheet 2 and is almost completely inside the sheet 2. buried evenly. After performing the high-pressure liquid treatment in this manner, the object to be treated is dried and cut into appropriate sizes. Incidentally, when performing such a treatment, it is preferable that the sheet 2 has a thickness of 57 nm or less, and if it is thicker, the elasticity of the sheet 2 will cause the fiber group 3 to be efficiently inserted into the inside of the sheet 2. It is difficult to bury and has low permeability to body fluids, making it undesirable as an exterior material. Further, the fiber density of the fiber group 3 is not particularly limited, but the finer the denier, the more preferable it is. As described above, the present invention
Since the fiber-embedded foam 1 is used as an exterior material for sanitary products, it is extremely thin. Shaped sanitary products also have excellent flexibility and elasticity, and do not twist when worn, making it possible to eliminate the drawbacks of conventional sanitary products mentioned above at once.

。Moreover, in the fiber-embedded foam 1, the hydrophilic fiber group, the hydrophobic fiber group, or the mixed fiber group 3 are almost uniformly distributed inside and outside the flexible foam sheet 2, so that it can be used as a sanitary product. The outer surface has a cloth-like feel, and body fluids absorbed in the absorbent body 4 are released by pressure and are less likely to ooze out from the surface of the sanitary product. It also depends on the amount of fiber-planted foam 1 used.
In sanitary products that were used relatively little,
Since the surface of the foam sheet 2 comes into pressure contact with the wearer's shorts, etc., there is an effect that there is little deviation from the pressure contact position due to the friction effect, and this is extremely useful for practical use. Example As shown in FIG. 4 and FIG.

倍となつていることが確認された。The thickness of the foam sheet 2 and the basis weight of the web 12 were as shown in the table below. In addition, the * mark in the table below indicates that after the web 12 was placed on the foam sheet 2 and treated, it was turned over, the web 12 was placed on top of it again, and the sheet was treated with the water jet. As shown in FIG. 6 as a partially enlarged schematic cross-sectional view, the fiber-embedded foam 1 obtained by the treatment has a fiber group 12 of a web 12 on the upper surface of the foam sheet 2.
It was confirmed that the web 12 was distributed and reached the inside of the foam, and as shown in a partially enlarged schematic cross-sectional view in FIG. It was confirmed that the fiber group 12a of the web 12 was distributed on the lower surface of the sheet 2 and reached the inside thereof, and that the distribution density of the fiber group 12a inside the sheet 2 was almost double that shown in FIG. .

In the case of a web with a web area weight of 20y/TTt, the sheet is so thick that the fibers of the web cannot be sufficiently embedded in it.
In addition, the water permeability was lower than that of nonwoven fabrics conventionally used as exterior materials for sanitary products, making them inferior products.
