Since the fibers are cut into pieces and compressed, their end surfaces are not covered with fiber-bonded nonwoven fabric pieces, which is insufficient to prevent the fibers from falling off. In addition, since the fiber-bonded nonwoven fabric piece is simply superimposed on the fiber accumulation piece, when the tampon swells to some extent due to the absorption of menstrual blood, it causes delamination from the fiber accumulation piece and prevents further menstrual blood flow. may reduce the rate of absorption.

もある。 As shown in Figures 1 and 2, the constituent material 1 of the tampon is made of hydrophilic fibers such as cotton rayon fibers alone or in combination, and is made by cutting into octagons from a web in which the fibers are simply accumulated. A fiber-bonded nonwoven fabric piece 3 obtained by cutting into octagons from a nonwoven fabric made of hydrophobic fibers such as polyester or polypropylene in which the fibers are not only accumulated but also bonded to each other is used. The fiber-bonded nonwoven fabric pieces 3 cover both sides of the fiber accumulation piece 2 and have a size such that they slightly extend from opposite positions on every other side of the octagon. The fiber accumulation piece 2 is sandwiched between two folded fiber-bonded nonwoven fabric pieces 3,
The fiber-bonded nonwoven fabric piece 3 is joined by heat welding at a portion 4 extending from the side edge of the fiber accumulation piece 2 and meeting each other (excluding the folded part of the fiber-bonded nonwoven fabric piece 3), leaving the outermost edge, Reference numeral 5 indicates the joint portion. The fiber-bonded nonwoven fabric piece 3 may be cut into two octagonal pieces having a size that covers each of both sides of the fiber accumulation piece 2. In this case, as will be described later, the fiber-bonded nonwoven fabric piece 3 on the surface of the component material 1, which will be located inside the component material 1 when it is press-molded into a columnar body, may have a hydrophilic property. Materials made of fibers may also be used.

The thinner the fibers of the fiber-bonded nonwoven fabric piece 3, the smoother the texture, so it is preferable that the fibers be as thin as possible. However, with current spinning technology,
It is difficult to obtain a material of 0.7 d or less, so when using a material of 0.7 d or less, for example, it is made of two thermoplastic polymer components with poor adhesion to each other, and one component is bonded to the other. 1 to 5d that are separated into multiple layers that are continuous in the fiber direction than the components of

In some cases, fiber-bonded nonwoven fabric fragments are used (see Figure 9). This kind of nonwoven fabric is
For example, a known method for entangling fibers by high-speed fluid jetting involves jetting a fiber web with a high-speed jet of water on a support having a large number of independent protrusions, entangling the fibers and simultaneously distributing the fibers at the protrusions. It can be obtained by a method of The opening 6 has a shortest diameter of 0.5 to 5 mm and a porosity of the nonwoven fabric piece 3.

内に残ることがなく、きわめて衛生的である。(Effects of the Invention) According to the tampon of the present invention configured as described above, the fiber aggregate pieces are completely covered with the fiber-bonded nonwoven fabric that is the exterior material, and the fiber aggregate pieces are arranged so that they are opposite to each other on every other side of the octagonal shape. Since the mating portions of the fiber-bonded nonwoven fabric pieces extending from the position are fused together, the fibers of the fiber-bonded pieces will not be exposed, fall off, and remain in the vagina, making it extremely hygienic.

るようなおそれがない。 In addition, in a tampon, the fused (joined) part of the fiber-bonded nonwoven fabric piece located at the top of the tampon is generally harder than other parts due to hardening after hot melting, but the fused part is located at the outermost edge. Since the welded portion is positioned with a gap left behind, there is no risk that the fused portion will slide against the vaginal wall at an acute angle, causing discomfort or discomfort to the wearer, or causing damage to the vaginal wall.

Since it is not present on the entire octagonal piece (entire circumference), the fused portion will not be too concentrated at the tip of the tampon and the tip will not become too hard.
