Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an absorbent article having a nonwoven fabric and a method for manufacturing the same. In particular, it relates to improvement of a non-woven fabric as a material for absorbent articles such as disposable paper diapers and sanitary napkins, which are required to have good touch.

[0002]

2. Description of the Related Art Nonwoven fabrics are widely used as topsheets and backsheets for absorbent articles because their properties are easily changed. Further, in recent years, in order to obtain desired properties, a non-woven fabric laminate in which two or more non-woven fabrics are laminated is also used as such a sheet. In the top sheet composed of the nonwoven fabric laminate, a nonwoven fabric obtained from a web mainly composed of long fibers such as spunbonded nonwoven fabric is used for a layer that comes into contact with human skin, that is, a surface layer. This is because it has no fluff and is excellent in touch.

[0003]

However, spunbonded non-woven fabrics and the like are liable to cause irritation due to poor permeability of body fluids such as sweat and urine.

Therefore, it is conceivable to use a non-woven fabric obtained from a short fiber (discontinuous fiber) web such as a melt blown non-woven fabric, but the tip of the short fiber protruding from the surface stimulates the user's skin, Gives a rough feel. In particular, when the skin is irritated due to urination or the like, such irritation causes a rash. Also, as short fibers, polyethylene (PE) and polypropylene (PP)
When synthetic fibers such as polyethylene (PE) and polyethylene terephthalate (PET) are used, the cost is low and it is suitable for disposable use, but the irritation to the skin becomes stronger. Moreover, the nonwoven laminate is stiffer than if it were a single layer nonwoven, giving the user a stiff feel.

Therefore, a main object of the present invention is to provide an absorbent article having a non-woven fabric which has excellent permeability to body fluids such as sweat and urine, has less irritation to the skin, and has increased softness, and a method for producing the same. To provide.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The present invention relates to an absorbent article in which an absorber is interposed between a sheet located on the skin side of the user, that is, a top sheet, and a sheet located outside the product, that is, a back sheet.

<Topsheet> The topsheet of the present embodiment is a web in which a natural fiber is mixed with a surface layer obtained from a short fiber web and having the ends of the short fibers protruding from the surface suppressed by a heat roll. A non-woven fabric laminate of two or more layers including at least the above-mentioned surface layer and the second layer laminated.

The use of the surface layer obtained from the short fiber web is for improving the permeability of body fluid such as sweat and preventing rash.

As a method for forming a short fiber web, there is, for example, a melt blown method. That is, for example, a raw material polymer such as a crystalline propylene-based polymer is melt-extruded, and fibers spun from a melt-blow spinneret are blow-spun as an ultrafine fiber stream by a high-temperature and high-speed gas, and then collected on a collecting device such as a wire mesh or belt. To make ultrafine short fiber (discontinuous fiber) web.

In this case, in addition to the method of fusion-bonding the fibers to each other by the heat of the fibers themselves, other adhesion methods such as needle punching method, water jet (spunlace method), ultrasonic sealing and the like are entangled. It can be adhered by a treatment method or a heat fusion method using a hot embossing roll (calendering method or air-through method).

The average fiber length of the short fibers is usually 20 to 60 m.
m, preferably 40 to 50 mm. The average fiber diameter of the short fibers is usually about 1 to 30 μm, preferably about 2 to 10 μm. Furthermore, the basis weight of the surface layer is usually 1 to 50 g / m ² , and preferably 3 to
It is 30 g / m ² . The weight per unit area can be appropriately changed depending on the application.

The use of a material obtained from a web in which natural fibers are mixed as the second layer improves the softness of the laminate and also improves the speed at which body fluid permeates the surface layer to the user. This is because it always gives a refreshing feeling. That is, the speed of permeation of the body fluid into the surface layer is increased by the action of absorbing the moisture such as body fluid existing in the surface layer from the second layer. This effect is remarkably excellent when the surface layer is composed of a nonwoven fabric obtained from a short fiber web. In addition, it is not preferable to mix natural fibers in the surface layer because it gives a dull feeling to the user.

The method for forming a web in which natural fibers are mixed is not particularly limited, and other fibers are mixed in forming a web on a collecting device such as a wire mesh or a belt. The fibers can be bonded to each other by the same method as the melt blown method.

As the natural fiber, it is particularly preferable to use cotton. Examples of cotton include unbleached combed yarn, bleached bleached cotton, and fluff obtained from woven fabrics, knits, and the like. Also, cotton has a mass ratio of 3% to the top sheet.
It is preferably less than. This is because if the amount is 3% or more, the body fluid absorbed by the cotton may return to the surface layer and give a dull feeling to the user.

In this embodiment, synthetic fibers are used as fibers other than natural fibers (other fibers). Synthetic fiber
The type is not particularly limited, and examples thereof include amide type nylon, aramid, ester type polyethylene terephthalate (PET), wholly aromatic polyester (polyarylate), and polyolefin type polyethylene (P
E), polypropylene (PP), polyvinyl alcohol-based vinylon, and other synthetic polymers such as acrylic, polyvinyl chloride, polyvinylidene chloride, and polyurethane may be used as raw materials by appropriately selecting one or several synthetic polymers. it can. In particular, it is preferable to use synthetic fibers made of polyethylene (PE) and polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET) as raw materials.

As shown in FIG. 2, a non-woven fabric laminate 40 serving as a top sheet has a surface layer 34 and a second layer 35, and in the present embodiment, a third layer 36, which are further laminated and heat-melted by an air through 37. It is formed by putting it on. In the present embodiment, the nonwoven fabric laminate 40 has three layers, but two layers,
The number of layers can be appropriately changed to four layers or more. However, the basis weight of the nonwoven fabric laminate is usually 7 to 100 g /
m ² is preferably 10 to 70 g / m ² , and more preferably 10 to 50 g / m ² . This is because when the basis weight is large, the nonwoven fabric laminate becomes hard and gives the user a stiff sensation. In addition, 31, 32, and 33 are all card machines.

Method for forming laminated body, ie, surface layer 3
The method for laminating the fourth layer 35 and the second layer 35 is not limited to heat fusion by air through. For example, a method of directly depositing the fibers of one layer on the other layer to form a laminate, a method of laminating each layer and fusing by heating and pressurizing to form a laminate, hot melt adhesive, solvent-based adhesion It is also possible to adopt a method of adhering with an adhesive such as an agent to form a laminated body. When laminating each layer by thermal fusion, the entire contact surface can be thermally fused, or only a part of the contact surface can be thermally fused.

<Backsheet> The backsheet of this embodiment is made of a non-woven fabric containing cotton.
The cotton is mixed to improve the softness of the back sheet. However, the mixing ratio is preferably less than 20% by mass with respect to the back sheet. This is because if the content is 20% by mass or more, the backsheet becomes stiff and the flexibility of the backsheet is rather poor.

The mixing method and type of cotton are the same as those for the second layer in the top sheet. Further, the backsheet can also have a laminated structure.

<Surface Treatment of Surface Layer> As shown in FIG.
The non-woven fabric laminate 40, which is the top sheet, is used by the winder 3
Before being wound by 9, the surface is passed between smooth rolls (heat rolls) 38 having a smooth surface and a predetermined temperature. As a result, at least the surface layer 34, and in the present embodiment, the tips of the fibers protruding from the surface of the third layer 36 in addition to the surface layer 34 are thermally melted and suppressed. This restraining process will be described with reference to the schematic diagram of FIG. 5. Before the treatment, as shown in the upper part of FIG. 5, the tip portions of the short fibers protrude from the surface of the nonwoven fabric (the conventional nonwoven fabric is in this state). However, as shown in the middle part of the figure, the protruding tip portion is sequentially suppressed by a thermo roll (actually, the nonwoven fabric moves from the right side to the left side of the paper) moving from the left side to the right side of the paper, Finally, as shown in the lower part of the figure, a non-woven fabric having a smooth surface without protruding fibers is completed.

In this way, the surface of the surface layer 34 becomes smooth and the irritation to the skin is reduced. It should be noted that such suppression processing can be performed before the surface layer 34 is laminated.

In the restraining process, the heat roll 38
Is preferably heated to 120 to 130 ° C. 120
If the temperature is lower than 0 ° C, the heat-melting effect of the short fibers is weak, and the effect of suppressing the fiber tips becomes insufficient. On the other hand, if the temperature exceeds 130 ° C., the heat-melting effect is large and the bonding range between the fibers is wide, and the effect of permeable body fluid due to the use of short fibers is impaired.

It is preferable that the above-mentioned restraining treatment is performed not only on the non-woven fabric laminate serving as the top sheet but also on the non-woven fabric or non-woven fabric laminate serving as the back sheet. However, in the case of the back sheet, it is not necessary to consider the bodily fluid permeability as in the top sheet, and therefore the heating temperature of the heating roll is slightly higher, preferably 125 to 140 ° C.

KES system (Kawabata Evaluation System) is used to suppress the non-woven fabric laminate with a hot roll.
When the surface characteristics according to (3) are performed under the following conditions, the smoothness becomes more preferable.

For this surface property test, "Frictional tester KESSE" manufactured by Kato Tech Co., Ltd. can be used. In the measurement, as shown in FIG. 1, a friction wire made of a piano wire having a cross-sectional diameter of 0.5 mm and having a contact surface length of 5 mm was moved while contacting the non-woven fabric sample with a contact pressure of 10 g. The average deviation of the friction coefficient is measured when the nonwoven fabric sample is moved by 2 cm at a speed of 0.1 cm / sec while applying a tensile force of 20 g / cm in the direction to the nonwoven fabric sample.

The mean deviation (MMD) of the coefficient of friction is MD
(Machine Direction) 0.01 to 0.50, CD (C
The ross direction) is preferably 0.01 to 0.70. This is because the non-woven fabric is improved in smoothness by suppressing the variation in smoothness.
The average deviation (MMD) of the friction coefficient is a value obtained by dividing the variation of the surface thickness when the friction element is moved, that is, the friction coefficient by the friction distance (moving distance = 2 cm). By setting the average deviation (MMD) of the friction coefficient within a predetermined range, a non-woven fabric that gives good smoothness and is less irritating to the skin is completed.

Adjustment of the mean deviation (MMD) of the coefficient of friction is
It can be appropriately set by changing the temperature of the heat roll, the rotation speed, the pressure, and the like.

<Others> The softness of the non-woven fabric can be improved not only by mixing natural fibers, but also by using a soft material. The soft material is preferably mixed with the raw material of the nonwoven fabric. Thereby, uniform softness can be expected over the entire nonwoven fabric.

As the softener, for example, a wax emulsion, a reactive softener, a silicone-based softener, etc. can be used, but it is preferable to use a surfactant. Examples of the surfactant include a carboxylate-based anionic surfactant, a sulfonate-based anionic surfactant, a sulfate ester-based anionic surfactant, and a phosphate ester-based anionic surfactant (especially alkylphosphorus Acid ester salts) and the like; sorbitan fatty acid esters, diethylene glycol monostearate, diethylene glycol monooleate, glyceryl monostearate, glyceryl monooleate, propylene glycol monostearate, and other polyhydric alcohol monofatty acids, N- (3-oleyloxy-2-hydroxypropyl) diethanolamine, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbit beeswax, polyoxyethylene sorbitan sesquistearate, polyoxyethylene monooleate Polyoxyethylene sorbitan sesquistearate, polyoxyethylene glyceryl monooleate, polyoxyethylene monostearate,
Nonionic surfactants such as polyoxyethylene monolaurate, polyoxyethylene monooleate, polyoxyethylene cetyl ether, polyoxyethylene lauryl ether; cationic surfactants such as quaternary ammonium salts, amine salts or amines ;

Zwitterionic surfactants such as aliphatic derivatives of secondary or tertiary amines containing carboxy, sulfonate, sulphate, or aliphatic derivatives of heterocyclic secondary or tertiary amines; Can be used.

If desired, known chemicals can be added to the softening agent as a secondary additive (minor component). Examples of this include saccharides such as sorbitol or glucose or a mixture thereof, flavors, colorants, preservatives,
Secondary additives such as antioxidants can be added.
