DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an incontinence liner worn in combination with incontinence pants or general underwear. More specifically, the present invention has a very thin and excellent flexibility while retaining a large amount of body fluid absorption and a high absorption rate, and is suitable for a wide range of incontinence from mild to moderate to severe incontinence in healthy subjects. About.

[0002]

2. Description of the Related Art Conventionally, disposable incontinence liners in which an absorbent sheet is interposed between a top sheet and a back sheet are attached to undergarments and the like for sanitary and incontinence products.
For example, light incontinence of a healthy person is considered as a very small incontinence amount of 10 cc or less, and it is not bulky during the wearing period until body fluid absorption, emphasizing long-term wearing comfort such as excellent biocompatibility and stuffiness, Top sheet material and basis weight,
There is known a disposable incontinence liner in which the air permeability of a liquid-absorbent sheet, the moisture permeability of a back sheet, and the water resistance are specified (Japanese Patent Application Laid-Open No. 9-154870).

In addition, various forms and sizes of incontinence pads for mild, moderate and severe incontinence are used mainly for the elderly and the sick, depending on the symptoms of incontinence, the amount of incontinence, sex, etc.
The basic configuration in which an absorbent sheet is interposed between a top sheet and a back sheet is the same as that of an incontinence liner. They are,
It is used by attaching it to ordinary underwear, incontinence pants, special covers or disposable diapers. There are known those having an outer shell forming a basin corresponding to moderate incontinence for healthy women (Japanese Patent Application Laid-Open No. 4-282153), urine absorbing pads used in combination with disposable diapers for the elderly and the sick, and the like. ing.

Further, an incontinence member is provided in the pants,
Absorb urine when urinary incontinence of women, elderly, sick, etc.,
Incontinence pants that are deodorized are used. There are various proposals for a method of attaching the incontinence member to the pants body. That is, in general, a cloth member obtained by laminating a water-absorbing member, a deodorant member, a waterproof cloth and the like is sewn to the crotch portion of the pants body, but (1) a waterproof cloth sewn to the pants body. A commercially available absorbent pad is removably housed on the inner surface and used as an incontinence member (Japanese Utility Model Application Laid-Open No. 61-18541).
No. 4, JP-A-5-91632), (2)
At least a portion of the incontinence member is sewn to the body of the pant and includes a positioned sack for receiving a separate moisture-absorbing pad.
No. 1, Japanese Utility Model Laid-Open No. 7-18708, Japanese Unexamined Patent Application Publication No. 8-2
No. 80726, etc.), (3) A removable water-absorbing auxiliary sheet or cloth is detachably attached to the inner surface side of the incontinence member sewn to the pants body (actually open flat 7-407).
07, JP-A-10-179624 and the like),
(4) A water-absorbing pad provided with an insertion / removal opening on the back surface of a water-permeable polymer sheet sewn to the pants body on the back surface, which is detachably provided by a fastening member (actual climbing). No. 3010579) is also known.

[0005] On the other hand, fluff-like wood pulp (hereinafter abbreviated as pulp) has been conventionally used as a main component of an absorbent sheet for absorbing moisture and body fluid used in absorbent articles.
And a so-called polymer absorber (hereinafter abbreviated as SAP)
Is generally used, which causes pulp to be bulky. In a general absorbent sheet composed of a combination of pulp and SAP, the higher the ratio of SAP, the more water absorbs, the more the gel blocking phenomenon based on the properties of SAP occurs, and there is a problem that the absorption capacity is not sufficiently exhibited. A highly water-absorbent sheet material formed on a sheet-like support by forming a composite composition in which polymer absorbent particles are coated and bound by microfibril-like fine fibers having hydratability obtained from cellulose or a cellulose derivative, is formed. It has been proposed (JP-A-10-168230).

[0006]

However, the above-mentioned liquid-absorbing liner has a very small amount of liquid absorption, a large amount of incontinence, or a sudden increase in the amount of pursuing the comfort of wearing. Has the drawback of giving anxiety to the elderly. A method of using an absorbent pad such as a commercially available sanitary napkin or incontinence pad directly or in a bag-like portion of the incontinence pants or the like and using the absorbent pad itself has a considerable thickness, In this case, there is a problem that the feeling of wearing is inferior because the storage part itself is considerably thick. On the other hand, general incontinence pants sewn with multiple cloth members, incontinence pants described in (3) above, auxiliary sheets and the like have the advantage of being washable, but are not sufficient in terms of absorption amount and thickness. In addition, since the auxiliary sheet and the like including the water-absorbing pad of the above (4) are relatively expensive and cannot be disposable, it is necessary to carry the used product when going out or traveling, which is troublesome and unsanitary. is there. Further, in the superabsorbent sheet material formed on a sheet-like support by forming a composite composition in which the SAP particles are coated and bound by the microfibril-like fine fibers, the ratio of SAP to the sheet-like support is high. Then, there is still a problem such as a decrease in the liquid absorption speed.

SUMMARY OF THE INVENTION The present invention has been made to address the above-mentioned problems, and has as its object the following:
While maintaining a large body fluid absorption amount and a fast absorption rate,
It is extremely thin, has excellent flexibility, and provides a suitable incontinence liner for a wide range of people from mild to moderately severe incontinence, thereby combining with incontinence pants or general underwear. It is an object of the present invention to provide an incontinence liner that can provide excellent liquid absorption performance when worn and does not reduce the feeling of wearing, is convenient to carry, and is cost effective.

[0008]

The inventors of the present invention have conducted intensive studies on an extremely thin incontinence liner while maintaining a large amount of body fluid absorption and a high absorption rate. In a disposable incontinence liner interposed, use an absorbent sheet having specific physical characteristics consisting of a specific component and composition as the absorbent sheet, and specify the specific position between the top sheet, the absorbent sheet, and the back sheet By interposing the components of the above, it was found that the above problem can be solved,
The present invention has been reached.

According to the present invention, there is provided a disposable incontinence liner having an absorbent sheet interposed between a top sheet and a back sheet, wherein A: as an absorbent sheet, (1) a hydratable microparticle obtained from cellulose or a cellulose derivative. An absorbent layer comprising a composite composition having fibril-like fine fibers and a particulate polymer absorber as main components and having a structure in which the particulate polymer absorbers are mutually bonded by the microfibril-like fine fibers. And a sheet-like support for supporting the absorbent layer, wherein (2) the particulate polymer absorbent has a gel elastic modulus of 8
× 103 N / m 2 or more, and the amount of pressure absorption after 60 minutes under a load of 40 g / cm 2 is 20 ml / g or more,
(3) The basis weight of the particulate polymer absorber on the sheet-shaped absorber is 50 to 500 g / m2, and (4)
A high-absorbency sheet having a pressure absorption of 5 ml / g or more after 10 minutes under a load of 40 g / cm 2 of the sheet-like absorber is used, and B: an acquisition sheet is interposed between the top sheet and the absorption sheet. An incontinence liner is provided.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
The hydratable microfibrillar fine fibers, the particulate polymer absorber, and the sheet-like support obtained from the cellulose or cellulose derivative used in the present invention are generally described in JP-A-10-168230. Those described can be used as they are. Also,
A structure in which a hydrated microfibrillar fine fiber and a particulate polymer absorber obtained from cellulose or a cellulose derivative are the main components, and the particulate polymer absorber is mutually bonded by the microfibril fine fiber. As a method of forming an absorbent layer comprising a composite composition having the above on a sheet-like support, the method described in the same publication can be applied as it is in principle.

[0011] That is, as the particulate polymer absorbent used in the present invention, general commercial SAP products for absorbent products can be used, and among them, water swellable materials such as polyacrylic acid and salts thereof are preferred. A polymer obtained by partially crosslinking a polymer, such as a sphere, a granule, or a flake, is suitable, and a relatively highly crosslinked polymer is particularly suitable. That is, the gel elastic modulus of the particulate polymer absorber is 8 × 10 3 N / m
It is preferably at least 2, more preferably at least 10 × 10 3 N / m 2. The pressure-absorbed amount of the particulate polymer absorber after 40 minutes under a load of 40 g / cm 2 was 2
It is preferably at least 0 ml / g, particularly preferably at least 25 ml / g. When the degree of crosslinking is low and the gel elasticity is low, the SAP itself can have a high water retention, but when it is made into a sheet-shaped absorbent, not only has the disadvantage that the blocking phenomenon due to the absorbing solution easily occurs, but also the sheet There is a problem that the drawback that the rigidity of the sheet-shaped absorber is significantly increased, and also, when manufacturing a sheet-shaped absorber described below,
There is a problem that the dispersibility of the SAP in the dispersion medium is poor. As a method for imparting a crosslinked structure to the particulate polymer absorber, any conventionally known method such as crosslinking during polymerization, crosslinking after polymerization, or surface crosslinking may be used. The particle size of the particulate polymer absorber is not particularly limited, and the main particle size distribution is 20 to 10
A 0-mesh SAP is preferably used, but when the particle size is large, uniform coating on the sheet-like support is difficult, which is disadvantageous for thinning, and when it is small, the absorption rate of the sheet-like absorbent tends to decrease. There is. In addition, a spherical one is advantageous in terms of uniform coating properties and thinning, but the particle shape is not particularly limited in the present invention.

On the other hand, as microfibril-like fine fibers, MF obtained by grinding and beating wood is used.
C (microfibrillated cellulose) is suitable, and for example, S-MFC (super microfibrillated cellulose) with further advanced microfibrillation described in JP-A-8-284090 is particularly suitable. SA
The ratio of the microfibrillated fine fibers to P is 1 to
If it is lower than this range, the bonding strength between the SAP and the sheet-like support is not sufficient, and if it is higher than this range, the rigidity of the resulting absorbent sheet becomes large. .

The composite composition containing the particulate polymer absorbent and the microfibrillar fine fibers as main components is cast on a sheet-like support as a dispersion liquid in which the composite composition is dispersed in an appropriate dispersion medium and dried. Thereby, a sheet-like absorber in which the absorbent layer made of the composite composition is formed on a sheet-like support is obtained. As the superabsorbent sheet used in the present invention, a sheet-like absorbent body having a pressure absorption amount of 5 ml / g or more after 10 minutes under a load of 40 g / cm2 is suitable.
Those which are 0 ml / g or more are particularly suitable. The composite composition may contain a short fiber component longer than the average particle size of the SAP, in order to complement between the SAP particles and between the SAP and the sheet-like support. As the sheet-like support, a porous non-woven fabric that facilitates the penetration of the dispersion liquid and is easily obtained by bonding with microfibril-like fine fibers is suitable, and the constituent materials of the non-woven fabric include cotton, rayon,
Hydrophilic materials such as wood pulp are preferred. The basis weight of the particulate polymer absorber in the sheet-shaped absorber is 50 to
500 g / m 2, preferably 100 to 400 g / m 2
m2. When the basis weight is smaller than this range, the absorption performance is not sufficient, and when the basis weight is larger than this range, the rigidity is undesirably increased.

At this time, the thickness of the sheet-shaped absorber is
Usually 0.2 to 2.0 mm, preferably 0.5 to 1.5 m
m. In addition, JI of the sheet-shaped absorber
Stiffness measured with a cantilever type tester of S (L1096) is usually 150 mm or less, preferably 20 to 12 mm.
It can be 0 mm. In addition, when the thickness or the softness is smaller than these ranges, it is likely to cause wrinkles and kinks when wearing the absorbent article, which may impair the effect of wearing.If it is larger than this range, wear it. This is not preferable because the feeling of discomfort at the time increases and wear comfort is impaired.

The basic structure of the incontinence liner of the present invention is constituted by using the above-mentioned highly absorbent sheet as an absorbent sheet interposed between a top sheet and a back sheet. The arrangement of the front and back sides of the superabsorbent sheet is not particularly limited, but it is preferable that the absorbent layer of the sheet-shaped absorbent body is arranged facing the back sheet side of the sheet-shaped support.
At this time, the diffusion function of the sheet-like support works effectively,
A high absorption rate is easily obtained.

As the top sheet, a liquid permeable sheet made of a fibrous nonwoven fabric, a porous plastic film or the like is used. On the other hand, as the back sheet, in the first embodiment, a liquid impermeable sheet such as a plastic film, a laminated sheet of the film and a fibrous nonwoven fabric, a microporous film, and a nonwoven fabric made of water-repellent cellulose fiber, preferably a breathable waterproof sheet However, in the second embodiment, a liquid-permeable sheet such as a fibrous nonwoven fabric can be used.

The incontinence liner according to the first embodiment, in which the top sheet is a liquid-permeable sheet and the back sheet is a liquid-impermeable sheet, has a leak-proof function by itself, and is used for ordinary underwear, incontinence. It is also suitable as a general use that is detachably attached to the body side of a disposable diaper, a special cover or a disposable diaper, or as an auxiliary pad that is attached to a bag-shaped part formed on incontinence pants or the like. In particular, it is suitable to be used by being worn on ordinary underwear. At this time, the edge of the back sheet is folded back to the top sheet side and adhered to the top sheet, or the periphery of the incontinence liner is wound around using a liquid-impermeable sheet such as a water-repellent nonwoven fabric separate from the back sheet. Alternatively, it is preferable to form a leak-preventing cuff extending to the top sheet side to prevent leakage from the end.

On the other hand, the incontinence liner according to the second aspect, in which both the top sheet and the back sheet are liquid-permeable sheets, can be inserted into and detached from the inner surface of a waterproof cloth of incontinence pants having a leak-proof function, or can be fixed. It is suitable to be used by being housed in the insertion / removal opening of the water-absorbing pad which can be detached by a member.

In any of the above-described incontinence liners, it is not always necessary to provide the top sheet with the function of preventing re-contamination as in the case of a sanitary napkin. Also, while the conventional incontinence liner tends to increase the wet back amount due to the thick pulp layer,
The incontinence liner of the present invention does not have such a drawback, particularly when used by being attached to a bag-like portion such as incontinence pants or an insertion / removal opening of a water absorption pad, between the incontinence liner and the body surface, Since the top sheet of the bag-shaped part or the constituent members of the water-absorbing pad are interposed, there is no need to consider the feeling of dryness on the surface of the top sheet at the time of liquid absorption and to minimize the re-wetting as much as possible. There is an advantage that a constituent material that emphasizes the diffusion function can be used.

In the incontinence liner of the present invention, an acquisition sheet is interposed between the top sheet and the superabsorbent sheet in addition to the basic components of the topsheet, the backsheet and the superabsorbent sheet. The acquisition sheet is also called a sublayer or a second sheet. As a material of the acquisition sheet, for example, a hydrophilic web such as an air-through thermal bond nonwoven fabric is suitable, and its function is to temporarily hold the discharged body fluid until it is absorbed by the highly absorbent sheet, and to move and transfer the fluid. It has been found that, in addition to the so-called acquisition effect which promotes the distribution, it has the effect of increasing the absorption of the incontinence liner. Since the highly absorbent sheet or sheet-like absorbent used in the present invention has a large body fluid absorption amount and a fast absorption rate, the acquisition sheet used here does not need to be bulky, and has a very low basis weight,
The thickness of the resulting incontinence liner hardly increases, since the thinner suitably fulfills its role. In addition, the top sheet and the acquisition sheet may be configured separately,
A configuration in which two layers of a top sheet and an acquisition sheet are combined in advance integrally may be used.

In the incontinence liner of the present invention,
In addition to the essential components of the top sheet, back sheet, superabsorbent sheet and acquisition sheet, a diffusion sheet may be interposed between the absorption sheet and the acquisition sheet or / and between the absorption sheet and the back sheet. it can. That is, the diffusion sheet may be interposed in the form of a sheet at any position on the upper and lower surfaces of the superabsorbent sheet, or the superabsorbent sheet may be included. As a material of the diffusion sheet, for example, a hydrophilic sheet such as tissue paper is suitable, and its function is to increase the absorption rate and / or the absorption amount of the incontinence liner.

In the present invention, the thickness of the top sheet, the back sheet, the acquisition sheet, and the diffusion sheet is not particularly limited.
5 mm. Therefore, the thickness of the incontinence liner of the present invention is 0.3 to 3.0 mm, preferably 0.6 to 2.5 mm.
mm. At this time, the thickness and weight of the incontinence liner and the appropriate flexibility of the incontinence liner based on the rigidity of the superabsorbent sheet can be realized in a well-balanced manner, and the wearing comfort is achieved.

When the incontinence liner of the present invention is worn in combination with incontinence pants or general underwear, underwear such as shorts, briefs, pantyhose, incontinence pants, exclusive cover, disposable diaper, etc. May be removably mounted on the inner surface of the body side of the body, or may be removably housed in an insertion opening of a bag-shaped portion provided on the inner surface of the incontinence pants or the like. There is no particular limitation on the detachable locking means in the former, and a generally used fastening member such as an adhesive sheet or a hook-and-loop fastener is provided on the back side of the back sheet or / and on the inner side of the incontinence pants or the like. Method can be used as it is.
