Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、排泄物を吸収保持する使い捨ておむつに関す
る。TECHNICAL FIELD The present invention relates to a disposable diaper that absorbs and holds excrement.
（従来の技術） 従来、使い捨ておむつにおいて、透水性表面シートと、
不透水性裏面シートの間に介在させた吸収体とを含み、
そして、前記表面シートとして多孔性を有するものを用
いるものが知られている。(Prior Art) Conventionally, in a disposable diaper, a water-permeable surface sheet,
Including an absorber interposed between the water-impermeable backsheet,
And what uses a porous thing as the above-mentioned surface sheet is known.
（発明が解決しようとする問題点） 前記多孔性表面シートを用いる理由は、尿が速かに前記
表面シートを透過して内部の吸収体に吸収される一方、
吸収された尿が前記表面シートから滲出しないようにす
るためである。したがって、前記表面シートの各開孔は
きわめて微小であり、いわゆる軟便（流動し易い液状大
便）は透過しない。(Problems to be solved by the invention) The reason for using the porous topsheet is that urine is quickly absorbed through the topsheet while passing through the topsheet.
This is to prevent the absorbed urine from seeping from the surface sheet. Therefore, each opening of the surface sheet is extremely small, and so-called loose stool (liquid stool that easily flows) does not penetrate.
ところで、おむつに、とくに乳児用のそれに軟便が排泄
されると、非多孔性表面シートはもちろんのこと、前記
多孔性表面シートでも目詰りを起こし、その結果、尿が
速かに透過しないばかりでなく、軟便が前記表面シート
上を面方向に流動して、着用者の股間部・臀部の全体を
軟便で汚されるとともに、軟便がおむつの外周縁から漏
れる、といった問題がある。By the way, when loose stools are excreted in diapers, especially for babies, clogging occurs not only in the non-porous surface sheet but also in the porous surface sheet, and as a result, urine does not immediately permeate. However, there is a problem that loose stools flow in the surface direction on the surface sheet, the entire crotch and buttocks of the wearer are soiled with the loose stools, and the loose stools leak from the outer peripheral edge of the diaper.
本発明の目的は、こうした問題点を有効に解決すること
ができる新規な使い捨ておむつを提供することにある。An object of the present invention is to provide a novel disposable diaper that can effectively solve these problems.

る。(Means / Examples for Solving Problems) The gist of the means of the present invention for solving the problems is a water-permeable top sheet, a water-impermeable back sheet,
In a disposable diaper including an absorbent body interposed between the front and back sheets, the front sheet maintains the shape by entanglement of hydrophobic fibers with each other and has pores having a diameter of 2 to 8 mm with a gap of 2 to 14 mm. And has a large number at least in a region corresponding to the upper surface of the absorbent body, the openings are formed by distributing the fibers, and a space of 6 to 12 denier is provided between the surface sheet and the absorbent body. The diaper is characterized in that a cushion fiber layer made of synthetic fiber and having a thickness of 4 to 10 mm and a density of 0.005 to 0.1 g / cm 3 is interposed.
さらに、本発明を図示の実施例に基づいて説明すると、
以下のとおりである。Further, the present invention will be described based on the illustrated embodiment,
It is as follows.
おむつは、透水性表面シート１と、不透水性裏面シート

ープファスナー７とを含む。The diaper has an absorbent body 3 interposed between a water-permeable topsheet 1, a water-impermeable backsheet 2, and front and backsheets 1 and 2.
And a cushion fiber layer 4 interposed between the topsheet 1 and the absorber 3. Furthermore, the diaper faces the back waist with the elastic member 6 attached downwardly in the longitudinal direction in the flap 5 formed by the front and back sheets 1 and 2 extending outward from the opposite side edges of the absorber 3. And a tape fastener 7 attached to the side.
表面シート１は、疎水性繊維が互に交絡して形態を維持
するとともに孔径２〜８mmで間隔２〜14mmの多数の開孔
８を有し、開孔８は、繊維が分配されることにより形成
されている。このような表面シート１を形成するには、
たとえば、突起群を有する支持体に繊維ウエブを導き、
その上面から高速水流を噴射して繊維交絡するとともに
繊維を前記突起群により周囲に分配する方法を用いれば
よく、このような方法は公知である。開孔８は孔径が２

へ逆流する。The topsheet 1 has a large number of openings 8 having a pore diameter of 2 to 8 mm and a spacing of 2 to 14 mm, in which hydrophobic fibers are entangled with each other to maintain the shape, and the openings 8 are formed by distributing the fibers. Has been formed. To form such a topsheet 1,
For example, guide the fiber web to a support having a group of protrusions,
A method in which a high-speed water stream is jetted from the upper surface to entangle the fibers and the fibers are distributed to the surroundings by the projection group may be used, and such a method is known. The aperture 8 has a hole diameter of 2
If the distance is 14 mm or less and the distance is 14 mm or more, loose stools do not permeate quickly and easily flow in the surface direction. When the pore diameter is 8 mm or more and the interval is 2 mm or less, the function as the surface sheet 1 is significantly reduced, and loose feces absorbed inside easily flow back to the surface.

維持するものが好ましい。The cushion fiber layer 4 is made of a synthetic fiber having a denier of 6 to 12 and has a thickness of 4 to 10 mm and a density of 0.005 to 0.1 g / cm 3 .
Denier 6 or less, thickness 4mm or less, density 0.005g / cm 3
If it is below, cushioning property, especially that under moistening,
Retention of loose stool is significantly reduced. When the denier is 12 or more, the thickness is 10 mm or more, and the density is 0.1 g / cm 3 or more, the rigidity is increased and loose stool does not easily penetrate. The cushion fiber layer 4 is
As long as the above conditions are satisfied, the fibers may be all made of hydrophobic fibers, but may contain an appropriate amount of known polyester fibers whose surface has been hydrophilically processed, and preferably the fibers are fused to maintain the shape. By doing so, those which maintain the layered state are preferable.

として実用に供しまことに有益である。(Operation and Effect of the Invention) Since the present invention is configured as described above, loose feces excreted on the topsheet 1 enter the cushion fiber layer 4 through the openings 8 and are retained, and The liquid content of the above is transmitted there and is absorbed by the absorber 3. Naturally, urine is quickly permeated through the cushion fiber layer 4 from the topsheet 1 and absorbed by the absorber 3. Moreover, the topsheet 1 and the absorber 3
Is isolated via the cushion fiber layer 4 having a large amount of space, so that the liquid content of loose feces and urine absorbed by the absorber 3 does not flow back and exude from the topsheet 1. Further, since the cushion fiber layer 4 has a cushioning property like letters, it not only gives the wearer a pleasant feeling of use, but when pressed, it passes loose stool through the large amount of space in the thickness direction / surface. It is possible to allow the stool to diffuse in the direction and then to hold the excreted loose stool. Furthermore, since the topsheet 1 and the cushion fiber layer 4 located on the absorbent body 3 have a large amount of space, the air permeability is very good and the stuffiness inside the diaper can be suppressed as much as possible. It is useful for practical use for infants excreting sick and sick people with diarrhea.
