Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an absorbent body and an absorbent article using the same, and more specifically,
The present invention relates to an absorbent body having improved adhesion to a wearer's body and improved absorption performance, and absorbent articles such as a urine pad, a urinary incontinence product, and a disposable diaper.

[0002]

2. Description of the Related Art Conventionally, absorbent bodies used in absorbent articles such as disposable diapers and urine pads are mainly composed of cotton-like pulp and absorbent polymer (hereinafter sometimes abbreviated as SAP). However, since a large amount of urine, sweat, and other body fluids are absorbed and retained, it can be used for a long time, and the amount of absorbent articles using such an absorber is increasing year by year.

On the other hand, in recent years, the thickness of the absorber has been reduced, and the proportion of cotton-like pulp having a large volume has been reduced to increase the proportion of SAP having a small volume and a large absorption amount. However, since SAP absorbs a large amount of body fluid but has a slow absorption rate, a thin absorber having a large proportion of SAP cannot absorb the entire amount by SAP alone when it comes in contact with a large amount of body fluid at one time. , Was causing the leak. Further, since the adhesion to the wearer's body is poor, a gap is created between the absorber and the body, which also causes a leak.

In order to solve such a problem, in JP-A-63-264971 and JP-A-3-206174, there is used a crosslinked cellulose obtained by crosslinking the inside of the fiber to improve the compression recovery property of the fiber. However, a method for improving the absorption rate is disclosed. However, in these methods, although the absorption rate of liquid is high, since the retention capacity is poor, the once absorbed body fluid returns to the top sheet, and the top sheet remains in a wet state forever, causing discomfort to the wearer. It may cause a rash when given. Further, the adherence to the wearer's body is still poor, and there is a possibility of leakage when used for a long time. Further, such a method has a problem that the cost of the product is high because the cellulose needs to be chemically treated, and the volume is large, which is disadvantageous in reducing the thickness of the absorber.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The absorbent body of the present invention comprises a top sheet, a back sheet, an absorbent material for absorbing and retaining body fluids disposed between these sheets, and an absorbent material disposed in the absorbent material. A compressed body, and at least a part of the compressed body is exposed from the topsheet surface. The absorbent body of the present invention having such a structure has a property that the compressed body expands its volume three times or more by absorbing liquid and further diffuses the absorbed liquid, and when the body fluid is discharged, The exposed portion of the compressed body absorbs and swells, and the body fluid diffuses and is guided to the absorbent material through the exposed portion, and is efficiently absorbed and retained in the absorbent material, so that the absorbent material is effectively used without waste. It is possible to obtain a good leak prevention effect.

In the case of the absorbent body of the present invention, it is preferable that the compressed body is exposed from the top sheet surface at the crotch part, particularly at the body fluid discharge port, so that when the body fluid is discharged, the exposed portion releases the body fluid. It is particularly effective when the discharge speed of the body fluid is high, because it absorbs and expands to increase the degree of close contact with the outlet, and the guide function of the exposed portion diffuses and guides the body fluid into the absorbent material. In particular, in the case of a woman, the body fluid discharge port is concave, and thus the discharged body fluid often flows along the body part to cause leakage, and thus the adhesion is important. In addition, it is preferable that the exposed part of the compressed body is located in the crotch part even if it is not located at the body fluid discharge port. The exposed part absorbs the body fluid accumulated in the crotch part and diffuses it into the absorbent material. , It is effective when a large amount of body fluid is discharged at one time.

Furthermore, it is preferable that at least a part of the compressed body is exposed on the surface of the absorbent material and the remaining part is embedded in the absorbent material. By such an arrangement,
When body fluid is guided to the compressed body in the absorbent material, the compressed body absorbs and expands to push up the absorbent material, and voids for temporarily holding body fluid are formed in the absorbent material. The absorption efficiency of can be increased.

Further, in the compressed body, when at least a part of the compressed body is exposed from the top sheet surface at both side edges and / or both end edges of the absorbent body, the exposed portion of the compressed body absorbs liquid during body fluid discharge, It is preferable because it expands and functions as a leak preventive wall that prevents leakage of body fluid.

As the absorbent material constituting the absorbent body of the present invention, a material mainly composed of fluff pulp made of cotton pulp or non-wood pulp in the form of cotton is used in combination with an absorbent polymer. Absorbent paper alone, or a mixture or laminate of heat-fusible fibers is used. Further, in order to prevent the absorbent polymer from popping out, it may have a laminated structure in which the whole is wrapped with a tissue. Further, in order to make it thinner and compact, it is preferable to use one having a constitution containing 50% or more of a water-absorbing polymer.

As the absorbent material suitable for the present invention, a sheet-like composite comprising a non-woven fabric substrate, a water-absorbent polymer and microfibril cellulose is used. More specifically, a coating solution prepared by dispersing an absorptive polymer and microfibril cellulose in a mixed solution of propylene glycol or methanol and water is applied to polyethylene-based, polypropylene-based, polyester-based, other thermoplastic resins, rayon, cotton, cellulose, etc. Is a sheet-like composite containing an absorbent polymer as a main component, which is applied to a coating substrate made of Microfibril cellulose is an ultrafine fiber having an average fiber length of 0.1 mm or less obtained by opening wood pulp under a high share. Since the sheet-shaped composite is obtained by coating a non-woven fabric with an absorbent polymer, line coating with an arbitrary width is possible. The coating pattern can be selected from a combination of front coat and line coat, or only line coat. In the absorbent body of the present invention, a plurality of the sheet-like composites may be stacked and used, or a belt-like sheet-like composite may be folded in multiple layers.

The compressed body used in the present invention has a property that the volume is swollen three times or more by absorbing liquid, and the absorbed liquid is diffused. The compressed body having such properties is
Natural fibers or synthetic fibers, preferably cellulosic fibers such as rayon, cotton, lyocell, acetate, etc., which are relatively short fibers having a fiber length of about 10 to 90 mm, or a mixture of these cellulose fibers and synthetic fibers. A compression-molded article is used in which the staple fiber is used to form a mat by a card web machine, and the mat is pressure-compressed at a high pressure.

As the compressed body used in the present invention, spunbond, card web and spunlace nonwoven fabrics made of polyethylene, polypropylene, polyester, etc., preferably TCF, Benlyse, rayon spun having good liquid permeability. A non-woven fabric made of a cellulosic material such as lace or air-laid pulp is folded into a mat shape and subjected to high pressure compression molding in a cell.
A compression molded body as disclosed in Japanese Patent No. 147694 is used.

Furthermore, as the compressed body used in the present invention, a filament bundle (tow) of acetate, polyester, polyethylene / polyester or the like, preferably a filament bundle obtained by subjecting these to hydrophilic treatment in order to enhance liquid permeability. A compression molded product such as a cigarette filter is used.

Further, the compressed body used in the present invention is a foam such as urethane foam, cellulose sponge, and PVA sponge, and preferably those obtained by subjecting these to a hydrophilic treatment in order to enhance the liquid permeability. Then, it is pressed into a cell and compression-molded into a spherical shape, a rod shape, or a band shape.

At least a part of the compressed body used in the present invention is exposed from the topsheet surface. The shape of the exposed portion of the compressed body can be any shape such as a rectangle, a square, a triangle, a circle, an ellipse, an annular shape, and a horseshoe shape.

When the entire compressed body is arranged on the surface of the absorbent material, it is necessary to bond and fix the compressed body and the absorbent material. As a method of adhesive fixing, there is a method of adhering a part or the whole of the adhering surface, and as an adhering means, there are hot melt adhesive, pressure melting, adhering by stitching and the like. In the case of adhering by suturing, this has an effect of not expanding only the adhering portion of the compressed body during swelling.

Further, since the exposed portion of the compressed body is a portion that comes into close contact with the wearer's body, it is preferable that at least a part of the compressed body is in a non-compressed state, particularly when it is located at the body fluid discharge port of the wearer. In particular, it is preferable that the portion is in a non-compressed state so that the portion can be softly adhered.
For such a non-compressed portion, for example, a compressed body is formed by the above-mentioned filament bundle, and the filament bundle in the portion of the exposed portion that is in close contact with the body fluid discharge port of the wearer is cut into the separated fiber portions. Can be formed by.

In the present invention, when the compressed body is formed of a highly hydrophilic material such as cellulosic fiber, a lack of dry feeling to the body is felt, and the surface such as cotton or tow is felt. If it is made of a material that causes fluffing, it may cause discomfort to the wearer when it comes into contact with the body.
It is preferable to cover with a liquid permeable sheet made of a hydrophobic material such as a synthetic fiber net or a polyethylene aperture film.

When the compression body is coated, it is necessary to prevent the liquid-permeable sheet from hindering the expansion of the compression body during use. Sometimes the liquid permeable sheet covers the compressed material,
It is then necessary to form the compact. Alternatively, a method may be used in which a compressed body is formed and then covered with a liquid-permeable sheet made of a stretchable material such as stretchable spunbond or elastic net.

As the top sheet used in the present invention, a liquid-permeable sheet made of a material generally used for sanitary materials is used. For example, polyethylene-based, polypropylene-based, polyester-based, and other non-woven fabrics such as synthetic fibers made of thermoplastic resin as a raw material, perforated non-woven fabric, and mesh sheet can be used.

As the back sheet used in the present invention, a liquid-impermeable sheet made of a material generally used for sanitary materials is used. As the liquid-impermeable sheet, a liquid-impermeable polyethylene sheet is widely used, but preferably a polyethylene sheet having micropores or a moisture-permeable sheet such as a stretched sheet obtained by adding a filler to a thermoplastic resin. The use of certain liquid-impermeable sheets reduces stuffiness and is comfortable. The liquid-impermeable sheet may be used alone or may be laminated with a plurality of nonwoven fabrics.

When the absorbent material of the present invention is used as an absorbent article in combination with another material, when the material combined with the back sheet is liquid impermeable, the back sheet is not necessarily liquid impermeable. However, it can be formed of a liquid-permeable material. It is preferable to form the back sheet from a liquid-permeable material because it has good air permeability and prevents stuffiness.

In the present invention, the absorbent article of the present invention can be used as it is or in combination with other materials to form absorbent articles such as a urine pad, a light incontinence pad and a disposable diaper.
