良に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to disposable diapers.More specifically, the present invention relates to disposable diapers. This invention relates to improvements in auxiliary absorbent materials for disposable diapers.

ている。('Prior Art) As is well known, disposable diapers that have been used in recent years consist of a liquid-permeable top sheet made of nonwoven fabric such as polyester, polypropylene, or rayon, a liquid-impermeable back sheet made of plastic, and both sheets. It mainly consists of an absorbent material made of water-absorbing paper, cotton pulp, superabsorbent polymer, etc. sandwiched between two layers, and it has become widely used because it is convenient to carry.

た。However, these conventional disposable diapers are made of absorbent material such as cotton pulp or super absorbent polymer so that they can be used even at night when the diaper is used for a long time, in other words, so that they can completely absorb two to three times of urine. During the daytime, when diapers are only used for a short time, diapers are changed more frequently than during the night, and diapers are often discarded with unsucked absorbents still remaining. However, they are not only wasteful in terms of cost and resources, but also have problems such as being thick and bulky, making them difficult to wear, and having poor fit. Additionally, there has been a problem in that the amount of waste is increasing, which has recently become a problem.

漏れを生ずるといった問題点がめった。In addition, in order to avoid waste, reducing the amount of absorbent materials such as cotton pulp and super absorbent polymers will not be a problem since diapers will need to be changed frequently during daytime use.
When used at night, the problem was that it could not absorb enough urine for two or three times, resulting in leakage.

The top sheet is liquid-permeable, but the back sheet is equipped with a liquid-impermeable film or a leak-proof film such as laminated paper to prevent liquid from leaking.The purpose of the auxiliary absorbent material of the present invention is to In order to solve the above-mentioned problems, which have completely different functions and structures, the present inventors have conducted extensive studies,
A liquid-permeable and liquid-absorbing disposable diaper in which an absorbent body made of absorbent paper, cotton-like pulp, and superabsorbent polymer is sandwiched between a liquid-permeable top sheet and a liquid-permeable back sheet. We have already proposed an auxiliary absorbent material for disposable diapers.

むつの補助吸収材である。(Means for Solving the Problems) The present invention provides a liquid-permeable and liquid-absorbing disposable diaper that has an absorbent body between a liquid-permeable top sheet and a liquid-permeable back sheet. This type of auxiliary absorbent material for disposable diapers is characterized in that part or all of the peripheral area of the outer sheet has been subjected to a permeation treatment for several years.

ットなどが使用出来る。As the topsheet used in the absorbent material of the present invention, nonwoven fabrics made of materials such as polyester, polypropylene, or rayon, which are used in conventional disposable diapers, can be used. It is of course possible to use the same material as the top sheet for the back sheet, but it is preferable to use a material that has 69% adhesion with the top sheet of disposable diapers and is inexpensive. Film, net, etc. can be used.

の液透過性が悪化し、漏れが生ずる可能性がめる。Methods for permeation treatment of the back sheet include coating with hot melt resin to make it impermeable to liquids, coating with water repellent such as silicone, fluorine, etc., or thin synthetic resin. Methods include attaching a material such as a film, laminated paper, water-repellent nonwoven fabric, or paper to the periphery of the absorbent material, but any method may be used. It is desirable that the area subjected to permeation treatment in recent years does not exceed 1/3 of the entire back sheet. If it exceeds 1/3, the liquid permeability of the absorbent material will deteriorate and there is a possibility that leakage will occur.

の吸収量がオーバーし、漏れにつながる可能性がめる。For areas that will undergo permeability treatment for several years, the treatment may be applied to the entire peripheral area of the absorbent material, or it may be applied to only the side edges in the longitudinal direction. It is desirable that the distance is 1° or more and less than 30 points from the edge of the absorbent material. If it is less than 1゜■, the leakage prevention effect of the absorbent material will be insufficient and there is a possibility that leakage will occur from the edges.If it is more than 30゜■, the area of the liquid permeation part will decrease and the absorption amount of the absorbent material will be excessive. This may lead to leakage.

である。In addition, as a pressure-sensitive attachment means for attaching the back sheet of the auxiliary absorbent material to be integrated with the disposable diaper, a known adhesive for sanitary napkins can be used, but conventional adhesive tape for sanitary napkins can be used. From the perspective of liquid permeability, it is undesirable to provide the absorbent material in the center of the auxiliary absorbent material, and it is desirable to provide it in the side edges of the absorbent material after several years of permeation treatment. This adhesive means can also serve as a permeation treatment for several years.

ておむつの厚さに較べ薄いことが望ましい。The size of the auxiliary absorbent material of the present invention is the same as the size of the absorbent material of the disposable diaper, so the smaller one is worn! Alternatively, it is desirable from the viewpoint of fit. The thickness of the auxiliary absorbent material is also desirably thinner than that of a disposable diaper from the viewpoint of wearability and fit.
