されている。2. Description of the Related Art A sanitary napkin is basically composed of a liquid-permeable surface material, a liquid-impermeable leakproof material, and a liquid-retentive absorber sandwiched between them. In recent years, with the development of technology, the absorption performance has been improved by introducing new materials such as absorbent polymers and film-type surface materials. On the other hand, to improve the performance of napkins made of these excellent materials, methods of stabilizing the mounting of napkins on shorts and preventing leakage have been studied.For example, the non-skin contact side of napkins By stabilizing the mounting by enlarging the area of the (back side) adhesive tape, and further extending flexible ear pieces from both ends in the width direction of the napkin and wrapping these ear pieces in shorts, it is even better. There has been proposed a method for stabilizing mounting and preventing leakage.

に両面テープを配設したナプキンが提案されている。In order to further improve the leakage prevention effect, it has been proposed to provide an adhesive on the skin contact surface side of the napkin to prevent the napkin from shifting. For example, Japanese Utility Model Publication No. 55-37129 proposes a napkin characterized in that an adhesive material mainly composed of a silicone rubber-based substance is provided on a part of the napkin on the skin contact surface side. Japanese Utility Model Laid-Open Publication No. Sho 60-166323 proposes a napkin in which a double-sided tape is provided on the skin contact surface side.

レによる漏れに対しては殆ど効果がない。However, the above-mentioned method of stabilizing the mounting of the napkin and preventing the leakage can effectively prevent the leakage from the crotch, but has almost no effect on the leakage due to the displacement of the discharge point. There is no.

的なものであるとは考えられない。The above-mentioned Japanese Utility Model Publication No. Sho 55-37129 only discloses that a specially processed silicone rubber-based substance is used as an adhesive, but does not disclose its adhesive properties. Not only silicone rubber-based materials, but rubber-based adhesive materials can be made from extremely strong to almost non-adhesive materials by blending. I don't think it will be. In particular, considering that the adhesive is used on the skin contact surface side of the napkin, the napkin described in the above publication using the adhesive is not considered to be practical.

供し得ないものである。[0006] The above-mentioned Japanese Utility Model Application Laid-Open No. 166323/1985 does not disclose the material and adhesive properties of the adhesive used for the double-sided tape. Assuming that a normal adhesive tape is used as the double-sided tape, the napkin having the adhesive tape on the skin contact surface side has good adhesion to the skin, but it is hardly considered that it can be easily detached, but it is considered to be practically usable It cannot be provided.

として股間や臀部からの漏れである。As described above, various methods for preventing leakage have been proposed, but none of the methods can be sufficiently satisfactory, and the first complaint of the user regarding the sanitary napkin is that the user still suffers from the crotch or buttocks. It is a leak.

ある。Accordingly, it is an object of the present invention to minimize discomfort when worn, to prevent slippage during wearing, to have good adhesion to the body, to prevent leakage from the crotch and buttocks, and to more easily attach and detach. An object of the present invention is to provide a sanitary napkin that can be made and that does not leave a sticky feeling on the skin after attachment and detachment.

Preferably, it contains 2 to 15% by weight of a water-soluble polymer substance, 0.2 to 2% by weight of a crosslinking agent and 40 to 70% by weight of water.

する。When the amount of the water-soluble polymer substance is less than 1% by weight, the shape retention of the gel cannot be maintained, and 30% by weight or less.
If it is more than 1, the gel becomes hard and the tackiness is not given. When the amount of the crosslinking agent is less than 0.1% by weight, the crosslinking does not proceed, and when it exceeds 4% by weight, the crosslinking is too strong to cause water separation. On the other hand, if the water content is less than 30% by weight, the napkin is not easily detached and the sticky feeling remains on the skin after the napkin is detached.
