Furthermore, toilet paper material can also be used as the raw material pulp. In this case, for example, softwood bleached kraft pulp obtained from conifers such as red pine, pine pine, todo pine, Douglas fir, hemlock, spruce and broadleaf trees obtained from broadleaf trees such as beech, oak, hippopotamus, eucalyptus, oak, poplar, alder, etc. Although what mix | blends bleached kraft pulp can also be used, it is preferable from a viewpoint on manufacture to use the raw material pulp which consists of softwood bleached kraft pulp.

Further, the pulp material content is preferably 30% or more, more preferably 50% or more. Furthermore, it is preferably 80% or more.

If the blending ratio of the pulp is as described above, the flexibility of the long paper 54 as a whole can be improved, and the production efficiency at the time of manufacture can be improved. Further, by increasing the blending of the pulp, the waste can be easily decomposed, for example, in soil after disposal. Therefore, the environmental load can be further reduced, and consideration for the environment can be further improved.

In addition, what mixed the said pulp with the above-mentioned nonwoven fabric may be used. That is, the above-mentioned pulp may be blended with a spunlace nonwoven fabric. Moreover, what mix | blended the said pulp with the airlaid nonwoven fabric may be used.

Further, the long paper 54 itself is preferably a single layer, but may be a plurality of layers. In the case of a plurality of layers, the thickness and material of each paper can be appropriately selected, and the same may be used or two or more may be used in combination.
The preferred basis weight of the long paper 54 varies depending on the material, for example, 7 is preferably from ~ 50 g / m ² if a single layer, and more preferably 10 ~ 30g / m ^2.

<Composite sheet forming process>
Next, as shown in FIGS. 11 and 12, one side surface of the elastic member 52 having elasticity in at least the conveying direction is provided on one side surface of the first long nonwoven fabric 50 extended in the raw material extending step. The elastic member joining region 60 is formed on one side surface of the first long nonwoven fabric 50.

Further, one side surface of the long paper 54 is joined to the other side surface of the elastic member 52 in the elastic member joining region 60, and the second long nonwoven fabric 56 is joined to the other side surface of the long paper 54. Thereby, the composite sheet 70 having a cross-sectional structure as shown in FIG. 12B is formed (composite sheet forming step). In addition, although the code | symbol 28 is a skin contact surface which contacts skin when a user wears the clothing 10 for disposable lower body, the 2nd elongate nonwoven fabric 56 may be a skin contact surface.

As shown in FIG. 12A, the composite sheet 70 includes a front body corresponding portion 20c and a front body portion in the width direction orthogonal to the conveying direction in order from the one side end portion 70a toward the other side end portion 70b. It has an equivalent portion 22c, a crotch equivalent portion 24a, a back trunk equivalent portion 22d, and a back body equivalent portion 20d.

The composite sheet 70 may be simply laminated as it is, but if the composite sheet 70 is pressed by the pressing means 72 from the thickness direction, the long paper 54 can be softened in particular, and the completed disposable lower body is used later. The comfort of the garment 10 can be improved.

The pressing means 72 is not particularly limited, and examples thereof include a flat roll and an uneven roll.

The joining between the members constituting the composite sheet 70 is not particularly limited, and known joining

means

76 and 78 can be used. For example, a hot-melt adhesive, an organic solvent adhesive, or a water-soluble adhesive can be used. It is preferable to use an adhesive, and a hot melt adhesive is more preferable.

Examples of the hot melt adhesive include known adhesives such as EVA (ethylene vinyl acetate copolymer), PO (polyolefin), PA (polyamide), SR (synthetic rubber), and ACR (acrylic). , PUR (polyurethane / moisture-curing type) and the like are all preferably used. These may be used alone or in combination of two or more.

These adhesives can be applied by at least one of planar coating, linear coating, dot coating, continuous coating, intermittent coating, spiral coating, wave coating, block coating, stripe coating, and staggered coating. It is preferable.

When a plurality of elastic yarns 58 are used as the elastic member 52, an adhesive is applied as the joining means 76 to the outer surface of each elastic yarn 58, as shown in FIG. In this state, the first long nonwoven fabric 50 may be bonded to one side surface of the elastic member 52, and one side surface of the long paper 54 may be bonded to the other side surface of the elastic member 52. In this figure, the long paper 54 is expressed in a zigzag, but this is a convenient representation of the unevenness provided by embossing, which will be described later, and does not limit the shape.

Moreover, the elastic member joining area | region 60 formed in the one side surface of the 1st elongate nonwoven fabric 50 is provided in the whole surface of the 1 side surface of the 1st elongate nonwoven fabric 50, or at least 1st elongate nonwoven fabric 50 It is provided on a part of one side surface of the nonwoven fabric 50.

If the elastic member joining region 60 is provided on the entire surface of one side of the first long nonwoven fabric 50, all the parts of the waist part 20, the trunk part 22, and the crotch part 24 of the disposable lower body clothing 10 that is the final product. However, since it has elasticity in the left-right direction in FIG. 1 or FIG. 2, the disposable lower body garment 10 that fits comfortably to the user can be manufactured.

Further, even if the elastic member joining region 60 is provided in a part, the elastic member joining region 60 of this part is formed so that at least the periphery of the crotch part 24 of the disposable lower body garment 10 which is the final product has elasticity. As long as it is located in the periphery, the periphery of the crotch part 24 has elasticity in the left and right directions in FIG. 1 or FIG. 2, so that the disposable lower body garment 10 that fits comfortably to the user can be provided. Can be manufactured.

Here, the long paper 54 bonded to the other side surface of the elastic member 52 may be embossed by the embossing means 12 in advance before the composite sheet 70 is formed.

By embossing the long paper 54, wrinkles can be provided on the long paper 54 as weak parts, punching holes, punching, appropriate holes, fissures, incisions, and the like.

The wrinkles are intended to cause the long paper 54 to expand and contract following the pulling of the composite sheet 70, as well as a three-dimensional design and viewing angle that cannot be expressed by printing with the printing means 14 described later. It is also for expressing designs with different nuances. As another effect, in the disposable lower body garment 10, there is also a side face that prevents the user's skin and shadow from being seen through. At this time, if the light shielding rate is 75% or more, the user's skin and shadow are not seen through, and the resistance feeling when worn by the user can be eased.

Also, the hole is for improving air permeability and giving the long paper 54 elasticity.

As an example of the shape of a wrinkle applied by embossing, for example, as shown in the perspective view of FIG. 13, a wavy unevenness repeatedly applied so as to wave in the conveying direction as a cross-sectional shape can be mentioned. The embossing may be provided on the entire surface of the long paper 54 or may be provided partially. The embossing is not particularly limited, and it is desirable to appropriately select a desired position.

The long paper 54 subjected to such embossing may be printed by the printing means 14 before embossing.

For printing, for example, a method such as ink jet or flexographic printing can be used, and it is particularly preferable to use flexographic printing. Further, the printing surface may be subjected to color fading prevention treatment by varnishing or adding a binder. Examples of the binder include known materials such as PVA, CMC, EVA, acrylic, and lacquer. Ink that has been subjected to color fading prevention treatment can also be used.

Note that the flexographic printing method has advantages such as a small contact area between the plate and the long paper 54 and a low printing pressure. For this reason, it is easy to peel the long paper 54 from the plate, and it is particularly suitable when printing on the thin long paper 54.

In addition, the flexographic printing method has many types of ink that can be used. In this respect, the flexographic printing method has less adverse effects such as being restricted by the ink viscosity and has a high degree of freedom compared to the ink jet printing method in which ink is ejected through a nozzle. In addition, when a pattern is expressed as a print on the long paper 54 after embossing, the pattern printed on the plate can be used by extending the long paper 54 in the expansion / contraction direction (conveying direction) of the elastic member 52. A desired pattern can appear on the appearance of the disposable lower body garment 10.

It should be noted that at least one of a deodorant, an insect repellent, a fragrance, a waterproofing agent, an antibacterial agent, an antifouling agent and a softening agent may be contained in the raw material for printing.

In addition, as shown in FIG. 28, it is good also as the disposable lower body clothing 10 which has only the elastic sheet 40, without joining the absorber 44. FIG.

[Third embodiment]
Since the third embodiment is basically the same as the first embodiment, only the differences will be described.

As shown in FIG. 29, the third embodiment is the first in that only the absorber 44 is joined to the composite sheet 70 before the leg hole 26 is formed in the leg hole forming step. This is different from the embodiment.
Thus, even if it provides only the absorber 44 before providing the leg hole 26, the desired disposable lower body garment 10 can be manufactured without any problem.

[Fourth embodiment]
Since the fourth embodiment is basically the same as the first embodiment, only the differences will be described.

In the fourth embodiment, as shown in FIG. 30, after the leg hole 26 is formed in the leg hole forming process, the leg hole 26 is left as it is without undergoing the two-fold process. And a cutting step of cutting through the cutting means 90 so as to cross the composite sheet 70. Further, as shown in FIG. 31, the front body is formed at both ends 33a and 33b of the back body 20b formed by cutting. The second embodiment is different from the first embodiment in that the locking

members

98 and 98 to be locked to 20a are joined, and then only the absorbent body 44 is joined to the crotch portion 24 of the disposable lower body garment 10.

locking members

98 and 98 of the back body 20b are stopped by the outer surface of the front body 20a after the application of the garment is assumed.

The locking

members

98, 98 are not particularly limited as long as they are steadily locked to the surface of the front body 20a. For example, male members of a mechanical fastener, adhesive seals, A combination hook or the like can be used. There is no particular limitation on the method of joining the rear members 20b of the locking

members

98, 98 to both

end portions

33a, 33b, and the joining

members

98, 98 can be joined using a known joining method such as an adhesive or ultrasonic joining. .

Also in such a case, since the periphery of the leg hole 26 is expanded and contracted by the elastic member 52, the comfort of the disposable lower body garment 10 can be improved.

As mentioned above, although the preferable embodiment of this invention was demonstrated, this invention is not limited to this, For example, in the said Example, arrangement | positioning of the elastic sheet 40 and the absorber 44 is performed separately. However, the absorber 44 may be disposed on the elastic sheet 40 in advance, and the elastic sheet 40 with the absorber may be disposed. The long paper 54 that has been previously embossed may be used.
