Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin absorbent article used as a panty liner absorbent sheet for urine, a urine absorbent sheet for urinary incontinence patients, and the like,
In particular, the present invention relates to an absorbent article capable of exhibiting a deodorizing effect on the surface and an effect of suppressing alteration of body fluid when absorbing body fluid.

[0002]

2. Description of the Related Art Absorbent articles having a deodorizing effect are disclosed in JP-A-8-224270 and JP-A-9-271484.
There is one disclosed in the publication. All of these use tea leaves or catechins extracted from tea leaves as a deodorant component.

A first known example is Japanese Patent Application Laid-Open No. 8-22427.
Japanese Unexamined Patent Publication No. 0 discloses a hygiene article in which tea leaves are contained in the absorber, and further it is described that the surface sheet formed of the water-permeable nonwoven fabric contains tea leaves.

A second known example is Japanese Patent Laid-Open No. 9-27.
Japanese Patent No. 1484 discloses a disposable diaper to which epigallocatechin galard is attached.

[0005]

However, the sanitary garment described in the first known example basically contains tea leaves inside the absorbent layer, so that the menstrual blood and the like absorbed in the absorbent layer can be prevented. The main purpose is to exert a deodorizing effect on the liquid. Further, the first known example describes that the surface sheet contains tea leaves, but the surface sheet described in this known example is a water-permeable nonwoven fabric such as a mesh, It is difficult to hold tea leaves with a mesh-shaped nonwoven fabric.

The second known example discloses an invention in which a disposable diaper is dipped in an aqueous solution of epigallocatechin galard and dried, but this also has a relatively large volume of the disposable diaper of epigallocatechin galard. It is intended to be included in the absorption layer.

As described above, although there is a conventional idea that tea leaves or tea leaf extracts are contained in the absorbent article for the purpose of deodorizing effect, in all cases, tea leaves or tea leaf extracts are contained in the absorbent layer. The main purpose is not to include the tea leaf or the tea leaf extract in the surface sheet that directly contacts the skin. Further, in each of the above-mentioned known examples, when the surface sheet contains tea leaves or a tea leaf extract,
No specific solution is disclosed for surely holding the tea leaf or the tea leaf extract on the surface sheet so as not to easily fall off.

On the other hand, as a thin absorbent article, there is a sagging absorbent sheet called a panty liner. The absorbent sheet of this veil is thin and fixed to the crotch portion of the undergarment to give a feeling of use similar to a part of the undergarment. Since this absorbent sheet for vaginal discharge is thin and the absorbent layer does not have a large absorption capacity, excrement easily remains on the surface of the topsheet for a long time. Further, the thin absorbent sheet used by urinary incontinence patients is also thin, and urine is likely to be present on the surface sheet.

However, in these thin absorbent sheets, even if the above-mentioned tea leaf or tea leaf extract is held in the thin absorbent layer located inside the thin absorbent sheet, the deodorizing effect on the deposits and urine adhering to the surface sheet is eliminated. It is difficult to fully exert the effect of suppressing deterioration.

The present invention solves the above-mentioned problems of the prior art, and exhibits a deodorizing effect and a deterioration suppressing effect on the excrement adhering to the surface sheet even if the excrement is likely to remain on the surface sheet. The object is to provide an absorbent article that can be made.

[0011]

The present invention provides a liquid-absorbent surface sheet formed of at least one of natural fibers and regenerated fibers, or of at least one of natural fibers and regenerated fibers and synthetic fibers. It is characterized in that it has at least two sheets of a liquid-impermeable back sheet, and that the top sheet contains tea leaves or a tea leaf extract.

In the absorbent article, since the surface sheet contains at least one of natural fiber and regenerated fiber, the tea leaf or the tea leaf extract is applied to the natural fiber and regenerated fiber by intermolecular force, Coulomb force or hydrogen bonding force. It adheres due to the physical binding force such as and becomes hard to fall off. Therefore, it is possible to exert the deodorizing effect and the deterioration suppressing effect on the secretions and excretion from the body attached to the surface sheet.

For example, it is preferable that the surface sheet contains cotton fibers, and the tea leaves or the tea leaf extract is attached to the cotton fibers.

On the cotton fibers, tea leaves or tea leaf extracts can be attached by hydrogen bonding force, and since the cotton fibers are fibrillar, the tea leaves or tea leaf extracts are easily held between the fibers. Therefore, the tea leaf or the tea leaf extract is reliably retained in the surface sheet.

The surface sheet is a laminate of at least two non-woven fabrics, a non-woven fabric on the front side and a non-woven fabric on the back face, wherein the non-woven fabric on the front side is formed of only cotton fibers or contains cotton fibers. It is preferable that the side nonwoven fabric contains the tea leaf or the tea leaf extract.

When the topsheet is made of at least two non-woven fabrics, the topsheet has a high ability to absorb secretions and excretion, and it is not necessary to provide an absorption layer under the topsheet, or even if an absorption layer is provided. It may be thin, and it is easy to form a thin absorbent article. Further, by holding the tea leaf or the tea leaf extract on the surface side non-woven fabric of the surface sheet,
It is possible to exert the deodorizing effect and the alteration suppressing effect on the secretions and excrements adsorbed and attached to the surface portion of the surface sheet.

The tea leaf extract is a catechin. Further, it is preferable that the surface sheet contains a coloring agent, and for example, the color of the surface of the surface sheet containing the tea or the tea leaf extract and the coloring agent is JI.
S Z-8721-1993 3.1 It is preferably any of 10Y to 5B when the hue circle defined in FIG. 1 is viewed clockwise.

When the surface of the surface sheet has the above-mentioned color, the change in the color of the sheet due to the inclusion of tea leaves or the tea leaf extract in the surface sheet becomes inconspicuous, and the deodorization by the tea leaves or the tea leaf extract as a product is eliminated. , It is possible to visually feel the image that it has a bactericidal effect. In addition, the color due to alteration of the vaginal discharge and the color of urine can be made inconspicuous.

Further, the liquid receiving area may be formed only by the top sheet and the back sheet.

In the absorbent article of the present invention, the topsheet has the ability to absorb and retain liquid, and can effectively exert the deodorizing effect and alteration suppressing effect on the secretions and excrements absorbed by the topsheet. Thus, it becomes possible to form a thin absorbent article having no absorbent layer.

Alternatively, in the liquid receiving area, a hydrophobic or water repellent cushion layer may be provided between the top sheet and the back sheet.

When the cushion layer is provided, a soft feeling can be given when the absorbent article hits the wearer's skin. In addition, the secretions and excretions are mainly absorbed by the surface sheet and subjected to the action of tea leaves contained in the surface sheet, so that the deodorizing effect and the deterioration suppressing effect can be effectively exhibited.

As shown in an enlarged view in FIG. 3, the surface sheet 5 has a structure in which a front surface side nonwoven fabric 21 and a back surface side nonwoven fabric 22 are stacked. The front surface side non-woven fabric 21 and the back surface side non-woven fabric 22 are formed separately, and a large number of openings 23 are formed in a state where two sheets are stacked. This hole 2
3 is a combination of two non-woven fabrics 21 and 22
It is formed by supplying between heated hot embossing rolls and piercing the convex portions of the embossing rolls.

Alternatively, the front side non-woven fabric 21 and the back side non-woven fabric 22 are preliminarily heated and pressed by an embossing roll in the peripheral portion of the liquid receiving region 17 to be bonded, and then the opening 23 is formed by the hot embossing roll. It may be

The surface side non-woven fabric 21 is a spun lace non-woven fabric made of 100% cotton fiber which is a natural fiber. That is, it is a non-woven fabric in which fibers are entangled with each other by applying a water jet to a wet or dry fiber web formed from cotton fibers. The back side non-woven fabric 22 is a spun-lace non-woven fabric made of 100% rayon, which is regenerated cellulose fiber, and is also a non-woven fabric in which fibers are entangled by applying a water jet to a wet or dry fiber web. .

The surface side nonwoven fabric 21 has a basis weight of 10 to 10.
It is 50 g / m ² , for example 30 g / m ² . Back surface side non-woven fabric 22, the basis weight is 25~65g / m ^2, for example 45 g / m ^2. In the surface sheet 5, the basis weight of the back side nonwoven fabric 22 is larger than that of the front side nonwoven fabric 21, and the basis weight ratio of the back side nonwoven fabric 22 is 1.1 to 2 times that of the front side nonwoven fabric 21.

The surface side non-woven fabric 21 contains tea leaves or tea leaf extracts or tea leaves and tea leaf extracts together. The tea leaf extract is, for example, catechins extracted from green tea, and the catechins are a kind of polyphenol. The catechins are epicatechin, epicatechin garde, epigallocatechin, epigallocatechin garde, catechin garde, gallocatechin garde, and the like, and the tea leaf extract contained in the surface-side nonwoven fabric 21 is the catechins. One or more of the above or a mixture thereof.

For example, the tea leaf extract contains 31.5% by mass of epigallocatechin garde and 1 part of epigallocatechin.
7.2 mass%, gallocatechin 17.2 mass%, epicatechin 5.9 mass%, epicatechin garade 5.0
% By mass, 2.8% by mass of catechin garde, and 1.9% by mass of gallocatechin garde. Of these, epigallocatechin garde is the most active and can effectively exert deodorant and bactericidal effects, and therefore the tea leaf extract preferably contains 25 mass% or more of epigallocatechin garde, Those containing 30% by mass or more are more preferable.

The tea leaf extract is an extract obtained by extracting tea leaves or the like with water or hot water, or a mixture thereof.

The tea leaves are contained in a powder state, and the tea leaf extract is also contained in a powder state in the surface side nonwoven fabric 21. It is preferable to use those powders having a particle size of 2 μm or less because they are easily bonded to the front surface side nonwoven fabric 21.

No binder is provided on the surface side non-woven fabric 21 in order to fix the tea leaves or the tea leaf extract, and the tea leaves or the tea leaf extract is fixed mainly to the cotton fibers by a physical binding force. ing. The physical binding force as used herein means an intermolecular force or Coulomb force between the tea leaf or the tea leaf extract and the cotton fiber, a hydrogen binding force by the OH group on the surface of the cotton fiber, and further between the fibrillated cotton fibers. It is the holding power for the tea leaf or the tea leaf extract.

The fibril-like cotton fibers are entangled with each other by the physical binding force, and the tea leaves or the tea leaf extract is retained therein, so that the tea leaves or the tea leaf extract is less likely to fall off from the surface side nonwoven fabric 21. . Moreover, since no binder is used, the texture and softness of the surface of the front side non-woven fabric 21 are not impaired.

As a means for fixing the tea leaves or the tea leaf extract in the surface side non-woven fabric 21, zeolite,
Powder of a porous material such as amorphous carbon or silica, or microcapsules may be used and attached to the fibers via these.

The front side nonwoven fabric 21 is colored by containing a coloring agent together with the tea leaves and the tea leaf extract. A dye easily soluble in water is used as the coloring agent, and the front side nonwoven fabric 21 can be colored by a dyeing method in which the front side nonwoven fabric 21 is dipped in the solution and dried. Alternatively, a water-insoluble pigment or dye is mixed with water,
A fixing method may be used in which the surface-side nonwoven fabric 21 is dipped in the mixed liquid and then dried to fix the pigment or dye on the fiber surface. In addition, the surface of the surface side non-woven fabric 21 can be colored by a gravure or flexo printing method.

As the colorant, it is preferable to use a chlorophyll-based pigment which is highly safe to be used in medicines and foods and which is also a natural product, such as sodium copper chlorophyllin and sodium iron chlorophyllin. Alternatively, a phthalocyanine-based pigment such as copper phthalocyanine blue or copper phthalocyanine green which is water-insoluble and hardly reacts with catechins can be used.

In this case, the discoloration due to the oxidation of the catechins can be masked by coloring the cotton fibers with a pigment that does not chemically react with the catechins (oxidation-reduction reaction of polyphenols containing catechins).

A specific method of adding the tea leaves, the tea leaf extract and the pigment to the front side nonwoven fabric 21 is carried out by supplying cotton spunlace to a pad dryer type dyeing machine. In the pad dryer type dyeing machine, the tea leaf extract, the pigment and an aqueous solution to which a nonionic-anionic surfactant is added as a dispersant are placed in the pad portion, and the cotton spunlace is passed through the pad portion. The cotton spunlace is dehydrated between the rollers and dried by blowing air. At this time, it is particularly preferable to use hot air.

The color tone of the surface of the surface side non-woven fabric 21 containing the tea leaf or the tea leaf extract and the colorant is as follows.
Secretory substances (colorless to light brown) and urine (light yellow)
It is preferable that the image can be concealed and the image containing catechins can be visually expressed. The surface color of the surface side non-woven fabric 21 is preferably any one of bluish, greenish, and yellowish colors, or an intermediate color thereof. Specifically, JIS Z8
721-1993 3.1 Any color between 10Y and 5B when the hue circle of FIG. 1 is viewed clockwise is preferable. The color is more preferably 10Y to 10G, and further preferably 10Y to 10GY.

The hue of the surface of the surface side non-woven fabric 21 can be more concretely shown by measuring with a colorimeter. The hue can be measured using, for example, a color difference meter “CR-300” manufactured by Minolta. The outline of the measuring method using the colorimeter is to calibrate by pressing the measurement opening of the measuring head against a white calibration plate attached to the colorimeter. After the calibration, the measurement opening is pressed onto the surface side non-woven fabric of the measurement sample and the measurement button is pressed. After the measurement, check the measurement data of the sample on the display. In the display section, the hue of the sample surface,
Lightness and saturation are displayed. The preferred hue of the surface of the surface side non-woven fabric 21 obtained by this measuring method is 2.0 GY-
It is 8.0 GY.

The amount of the tea leaves or the tea leaf extract attached to the front side nonwoven fabric 21 is preferably 0.005 to 0.05% by mass, and more preferably 0.005 to 0.01% by mass. Further, the coloring agent is contained in an amount of 0.01 to 0.1% by mass with respect to the front surface side nonwoven fabric 21, and more preferably 0.1.
When it is contained in an amount of 02 to 0.05% by mass, a light color can be colored without impairing the feel of the nonwoven fabric.

The cushion layer 4 is a through-air non-woven fabric and is formed by fusing a core-sheath type thermoplastic composite synthetic fiber having a polypropylene (PP) core and a polyethylene (PE) core with hot air. ing. The cushion layer 4 is hydrophobic, and more preferably water-repellent treated by water-repellent treatment. The basis weight of the cushion layer 4 is 20 to 60 g / m ^2, for example 40 g / m ^2. The basis weight of the cushion layer 4 is smaller than the basis weight of the entire surface sheet 5 including the front side nonwoven fabric 21 and the back side nonwoven fabric 22, and the basis weight of the cushion layer 4 is 0. .3 to 0.8
It is a double range.

In this absorbent sheet 1, the surface sheet 5 is made of a hydrophilic front surface side nonwoven fabric 21 and a liquid back surface side nonwoven fabric 22, and the cushion layer 4 located thereunder is formed from the surface sheet 5. It has a small basis weight and is hydrophobic or water repellent. Therefore, the topsheet 5 functions as a substantial absorption layer.

Next, the back sheet 3 is formed of a liquid-blocking, hydrophobic or water-repellent nonwoven fabric. This non-woven fabric is a laminated body of spun bond non-woven fabric and melt blown non-woven fabric, and when the spun bond non-woven fabric is (S) and the melt blown non-woven fabric is (M), S / M. It has a three-layer structure of a laminated non-woven fabric of S and a non-woven fabric of M whose central part is also formed of PP fibers. The total weight of the back sheet 3 is 15 to 55 g.
/ M ² , for example, the laminated non-woven fabric of S · M · S on the surface side is 15 g / m ² , and the non-woven fabric of M in the central portion is 5 g / m ² ,
The laminated non-woven fabric of S, M and S on the back side has a weight of 15 g / m ² , and a total of 35 g / m ² .

The pressure-sensitive adhesive layer 6 is a rubber-based hot-melt adhesive, and is formed in a pattern extending in a strip shape in the longitudinal direction (Y direction) and in parallel. The release sheet 7 is formed by coating the surface of paper with a release resin layer such as silicone.

In the absorbent sheet 1 shown in FIGS. 1 to 3, the release sheet 7 is peeled off, and the pressure-sensitive adhesive layer 6 is fixedly attached to the inner surface of the crotch portion of the underwear. The topsheet 5 is formed of a front side nonwoven fabric 21 and a backside nonwoven fabric 22, the frontside nonwoven fabric 21 is formed of only cotton fibers, and the backside nonwoven fabric 22 is formed of rayon fibers only, and both nonwoven fabrics 21 and 22 are hydrophilic. . Therefore, the secretion or excretion from the body is
It is mainly absorbed by the two nonwoven fabrics 21 and 22. The cushion layer 4 functions as a cushion so as to give a soft feeling to the contact with the skin, and since the cushion layer 4 is hydrophobic or water repellent, it hardly exhibits a liquid absorbing function. The cushion layer 4 also has a function of supplementing the leakproof function of the back sheet 3.

Further, since the surface side non-woven fabric 21 formed of the cotton fiber appears on the surface of the surface sheet 5, the feeling of contact of the surface with the skin is soft. Further, the surface side non-woven fabric 21 contains tea leaves or a tea leaf extract and a colorant, but these tea leaves, tea leaf extracts and colorants are hard to fall off from the cotton fiber, and have excellent fixability to the front side non-woven fabric 21. .

The secretions or excretions absorbed by the surface sheet 5 are absorbed by the front surface side nonwoven fabric 21 and the back surface side nonwoven fabric 22, and the tea leaves contained in the front surface side nonwoven fabric 21 appearing on the outermost surface of the surface sheet 5. Alternatively, since the tea leaf extract exerts a deodorizing effect and a bactericidal effect, it is possible to suppress odor and alteration or decay of secretions on the outermost surface of the surface sheet 5. In particular, secretory substances such as paper drops tend to remain on the surface-side non-woven fabric 21 which is the outermost surface of the topsheet 5, but
Even if it remains, the deodorizing effect and the bactericidal effect can be effectively exhibited.

Further, since the front side non-woven fabric 21 is colored, the color of the secretion or excretion absorbed in the front side non-woven fabric 21 can be hidden, and the color of the secretion or excretion absorbed in the back side non-woven fabric 22 can be concealed. Can also be hidden.

As described above, in the thin absorbent sheet 1 whose surface sheet 5 mainly exhibits the liquid absorbing ability, the deodorizing and sterilizing effect of the tea leaves or the tea leaf extract can be obtained on the outermost surface, and the surface sheet A sufficient hiding effect can be exerted by the colored color on the outermost surface of the.

The present invention can be variously modified. For example, the topsheet 5 may be formed of three or more hydrophilic non-woven fabrics. In this case,
The surface side non-woven fabric located on the outermost surface may contain cotton fibers, and the cotton fibers may contain tea leaves or tea leaf extracts and a colorant.

The surface sheet 5 may be composed of one non-woven fabric formed of cotton fibers or the like, and the one non-woven fabric may contain the tea leaves, the tea leaf extract or the coloring agent.

Further, in the surface sheet 5, pulp which is the same natural fiber is used instead of cotton fiber, or both cotton fiber and pulp may be contained. The pulp also has a high ability to fix tea leaves, tea leaf extracts and colorants. Furthermore, when pulp is beaten and microfibrils appear on the surface, the ability to retain tea leaves and colorants can be enhanced by the microfibrils.

The surface side non-woven fabric 21 may contain rayon which is a regenerated fiber, or may contain synthetic fiber which is hydrophilically treated. In this case, synthetic fiber may be kneaded with the tea leaf extract or colorant.

Furthermore, the cushion layer 4 may be hydrophilically treated and may have a liquid absorption capacity, or a thin absorption layer such as pulp may be provided in place of the cushion layer 4. However, it is preferable that the weight of the hydrophilic cushion layer 4 or the thin absorbent layer is smaller than the weight of the entire surface sheet in order to form a thin absorbent article.

Further, since the topsheet 5 has a liquid absorbing capacity, the cushion layer 4 may not be provided, and the main body 2 may be composed of only the topsheet 5 and the backsheet 3.

[0063]

INDUSTRIAL APPLICABILITY As described above, in the thin absorbent article in which the surface sheet exhibits the liquid absorbing ability, the deodorant and sterilizing effects can be exerted on the secretions and excrements attached to the surface sheet. In addition, tea leaves or tea leaf extracts exhibiting deodorant and bactericidal effects can be easily fixed on the surface sheet, or a binder for fixing is unnecessary, and the texture of the surface sheet can be kept good.
