（産業上の利用分野）
本考案は、膣内に挿入して用いる生理用タンポ

内部に十分に浸透吸収されない。(Problems to be Solved by the Invention) Since the known tampon is covered with the exterior material, it has the effect of preventing the constituent fibers inside the tampon from fluffing up and falling off in the vagina. However, since the entire surface of the outer packaging material has substantially uniform liquid absorption or liquid permeability, the surface becomes extremely dirty with menstrual blood, which makes it difficult for the user to remove the tampon from the vagina. It may give you a feeling of pleasure. In addition, since the entire surface of the tampon has liquid absorbency or liquid permeability,
Menstrual blood is gradually diffused and absorbed on the surface of the tampon, that is, its diffusion is poor, and therefore the absorption rate is low. Furthermore, when the exterior material is a hydrophobic nonwoven fabric, liquid permeability is poor, so menstrual blood flows along the surface of the tampon and flows out of the vagina, and is not sufficiently penetrated and absorbed into the tampon.
本考案の目的は、主として前述のような問題点
を解決することができる生理用タンポンを提供す

In the sanitary tampon, the constituent material is compression-molded into a columnar body so that the nonwoven fabric is located on the surface of the tampon, the nonwoven fabric is given a sheet-like shape by intertwining fibers, and The non-woven fabric has a large number of independent pores formed by distribution of the fibers, the non-porous area of the non-woven fabric is substantially liquid-impermeable, and the pores are arranged with a diameter of 2 to 10 mm. The tampon has a pitch of 4 to 15 mm.

４はその接合部を示す。 As the constituent material 1 of the tampon, a web 2 made of hydrophilic fibers such as cotton rayon fibers or a mixture thereof, and a nonwoven fabric 3 made of hydrophobic fibers such as polyester or polypropylene are used. As shown in FIGS. 1 and 2, the fibrous web 2 is cut into rectangles, and the nonwoven fabric 3 is cut into rectangles of such a size that the nonwoven fabric 3 covers both sides of the fibrous web 2 and its periphery slightly protrudes. And fiber web 2
is covered with a non-woven fabric 3, and the peripheral edges where the non-woven fabrics 3 meet each other are linearly joined by thermal welding, and reference numeral 4 indicates the joined part.

れている。 The nonwoven fabric 3 has a fineness of its constituent fibers of 2d or less,
It is preferable that the area weight is 15 to 35 g/m 2 and the density is 0.05 to 0.4 g/cm 3 . Fineness is 2d or more, basis weight is 15
If the density is less than 0.05 g/cm 2 or less than 0.05 g/cm 3 , not only will it not be possible to obtain the smooth surface and good texture that this invention aims to achieve, but also the fibers will not be dense enough, resulting in poor liquid permeability. There are some difficulties in assigning . Weight is 35
g/m 2 or more and the density is 0.4 g/cm 3 or more, it becomes impossible to use the required amount of the fibrous web 2, which is a material for absorbing menstrual blood, and when using the required amount of the fibrous web 2, Because the diameter of the tampon is limited, the tampon becomes too hard after being squeezed. Regarding the fineness, the finer it is, the better, but with current spinning technology, it is difficult to obtain a fineness of 0.7d or less, so when using a fineness of 0.7d or less, for example, Consisting of two thermoplastic polymer components with poor properties,
Staple fibers, which are splittable composite fibers of 1 to 5 d, in which one component is separated by the other component into a plurality of layers continuous in the fiber direction, may be split by a carding machine or high-speed water jet treatment. Such fibers are disclosed, for example, in JP-A-57-56562.

公知の揆水剤で処理してもよい。 The nonwoven fabric 3 is given a sheet-like shape by intertwining the fibers, and has a large number of independent openings 5 formed by the distribution of the fibers. Such a nonwoven fabric can be produced, for example, by a known fiber entangling method using high-speed fluid jetting, in which a high-speed water jet is jetted onto a fiber web on a support having a large number of independent protrusions, and the fibers are entangled at the same time. It can be obtained by a method of distributing fibers at protrusions. Opening hole 5 has a diameter of 2
It is preferable that the diameter is 10 mm or more and the arrangement pitch is 4 to 15 mm. If the diameter is 2 mm or less and the pitch is 15 mm or more, the permeability of menstrual blood will be poor and it will not be absorbed sufficiently into the tampon, and if the diameter is 10 mm or more, If the pitch is 4 mm or less, the open pore area ratio becomes large and the nonwoven fabric 3
The significance of using it is halved. Note that the nonwoven fabric 3 is
To further improve liquid permeability in non-porous areas,
It may be treated with a known water repellent.

能を発揮することになる。(Operations and Effects of the Invention) According to the tampon of the present invention configured as described above, when the tampon is inserted into the vagina, the surface of the tampon is covered with the hydrophobic fiber nonwoven fabric, and the non-perforated area is substantially Since it is essentially liquid-impermeable, menstrual blood flows and diffuses without permeating through the non-perforated area, and at the same time, it permeates and is absorbed into the internal absorbent material through the perforations. Therefore, the non-porous area of the tampon is less likely to become soiled due to the water-repellent properties of its fibers, so it is relatively clean when removed from the vagina, and the absorption rate and amount of absorption are increased. , the absorbent material of the tampon is effectively utilized, and the tampon expands relatively quickly to perform its function of blocking menstrual blood.
