For example, a fastening tape (not shown) or the like is attached to the long extending portion. Further, the top sheet 1 and the back sheet 2 are joined at the extended portion where force is applied.
- the joining method is not particularly limited.
- the absorber 3 is entirely encapsulated by an encapsulating sheet 5 that also has a force such as crepe paper or tissue paper. By this encapsulation, the shape of the absorber 3 is maintained.
- the paper diaper 10 of this embodiment is not bonded with an adhesive such as a top sheet 1 and a second sheet 4 force hot melt.
- an adhesive such as a top sheet 1 and a second sheet 4 force hot melt.
- the top sheet 1 and the second sheet 4 are bonded together by applying at least one emboss 6 of heat embossing and ultrasonic embossing in a laminated state. Therefore, the problem that the surface sheet 1 is stiff due to the adhesive and the skin is liable to occur does not occur. Also, By providing the emboss 6, the top sheet 1 and the second sheet 4 are not in close contact with each other, and a void is not formed between these sheets 1 and 4.
- the bodily fluid is immediately absorbed by the absorbent body 3, and the bodily fluid stays in the powerful gap, and there is no possibility that the bodily fluid stays back through the surface sheet 1.
- the top sheet 1 and the second sheet 4 can be bonded together with an adhesive such as hot melt. In that case, the adhesive does not ooze out from the top sheet 1 even if embossing is applied.

It is preferable to have power. If the area of the emboss 6 is 5% or more of the laminated area of the top sheet 1 and the second sheet 4, the diffusion of urine and loose stool on the top sheet 1 is reduced. As shown in FIG. 1, in the present embodiment in which the second sheet 4 is covered with the top sheet 1, the laminated area when the embossed area is 100% is the same as the area of the second sheet 4. Further, as shown in FIG.
- the emboss 6 has a funnel shape that becomes thinner from the top sheet 1 side toward the second sheet 4 side. If the heat emboss 6 has a funnel shape in which the force on the top sheet 1 side also becomes narrower toward the second sheet 4 side, urine and loose stool accumulate in the heat emboss 6. Therefore, contact between the skin and urine or loose stool is reduced. Also, if the embossed 6 force surface sheet 1 side force is also formed into a funnel shape that becomes thinner toward the second sheet 4 side, urine and soft stool absorbed from the surface sheet 1 to the lower layer will return from the lower layer. Therefore, the return under load is prevented.

If the embossing temperature is less than 40 ° C, a sufficient embossing pattern will not be formed, and if it exceeds 250 ° C, the sheet will become hard. Also, when heat embossing is applied at 80 ° C or higher, the surface layer where the low melting point fiber such as C 2 O-PP does not melt completely melts, and the surface layer and the surface layer adhere. In addition, when heat embossing is applied at 250 ° C or less, only the surface layer of a material having a high melting point such as PET or acetate melts, and the fibers adhere to each other.
- a polyolefin fiber particularly polyethylene or polypropylene
- these resins have a melting point of 100 to 170 ° C.
- the embossing temperature is 80 to 180 ° C when embossing is applied to a non-woven fabric formed from fibers made from these coffins or fibers made from these coffins. It is preferable to give by. Further, in order to achieve both good adhesion and softness of the surface sheet and the second sheet, it is particularly preferable that the surface sheet and the second sheet are given at 100 to 130 ° C.
- 32 and embossing roll 40 which is also powerful, to top sheet 1 and second sheet 4 Gives a boss.
- embossing roll 40 a convex roll 31, a concave roll 32, and a force S variant are used.
- the surface sheet 1 and the second sheet 4 have a narrow area in contact with the user's skin, so that the resulting absorbent article such as disposable diaper 10 is less likely to cause rough skin such as a rash.
- the convex roll 31 and the concave roll 32 are different in force from the pattern shape of the convex roll 31 and the pattern shape of the concave roll 32 (even if one roll is a plain (flat), ) That! Uh.
- the shape and shape of the convex roll 31 and the concave roll 32 and the force are not particularly limited.
- the convex portion 33 has, for example, an inverted bowl shape that is a rhombus in the illustrated example, such as a circle, an ellipse, a square, a rectangle, a rhombus, etc.
- the boundary between the recesses 34 adjacent to each other has a lattice shape (lattice portion 36).
- the force of the convex roll 3 1 and the concave roll 32 is as shown in FIG. 12 and FIG. 13 (in FIG.
- the convex portion 33 has, for example, a circular end, an elliptical end surface
- the shape is a reverse mortar shape that is circular, such as a square, rectangle, or rhombus
- the boundary between the adjacent recesses 34 is a lattice shape (lattice-like portion).
- a configuration in which a narrow protrusion 37 is provided on the front end surface of the lattice-like portion 36 can be exemplified as a preferable example.
- the convex state of the convex roll 31 and the concave roll 32 is as shown in FIGS. 19 to 21 (in FIG. 20 and FIG. 21, the convex roll 31 is indicated by a dotted line).
- the emboss formed on the top sheet 1 and the second sheet 4 is adjacent to the cup part formed by the convex part 33 and the concave part 34 corresponding to the convex part 33 as in the previous embodiment.
- the convex portions 35 and the skin contact portion formed by the lattice-like portions 36 fitted into the convex portions 35 and has the same function and effect as the previous embodiment.
- the narrow protrusions 37 are provided on the front end surface of the lattice-like part 36, the skin contact part becomes narrower, and the absorbent article such as the disposable disposable diaper 10 is obtained on the skin. As the contact area with the surface becomes narrower, the skin becomes more difficult to roughen. Similarly, in this embodiment, since the narrow protrusions 37 are provided on the front end surface of the lattice-like part 36, the skin contact part is given more clearly, and the resulting disposable paper sheet is obtained.
- the absorbent article such as Mutsu 10 gives a waffle-like softness. Furthermore, if the unevenness is reversed, only the convex portion 33 comes into contact with the skin, so that the contact area with the skin is reduced, and a fluffy and soft quilted pattern can be obtained.
- the width of the second sheet 4 exceeds 120 mm, the strength of the adhesion part of the other sheet is lowered, which is not preferable. If the width of the top sheet 1 is less than 120 mm, it is not preferable because other sheets (such as gather sheets) cannot be bonded to the top sheet 1 and the adhesiveness is weak. If the width of the top sheet 1 exceeds 250 mm, it will be a wasteful material that can only be cut or cut into the absorber 3.
- the thickness of the top sheet 1 is less than 0.15 mm, it is difficult to produce the nonwoven fabric itself, and the appearance of the embossing is adversely affected by the density and uneven density.
- the thickness of the top sheet 1 exceeds the thickness of the second sheet 4
- urine and feces may be retained on the top sheet 1 and the absorption into the absorber 3 may be worsened.
- the thickness of the second sheet 4 exceeds 2.35 mm, the weight increases and the cost increases. Further, if the surface weight of the surface sheet 1 is less than 15 gZm 2, it is difficult to produce the nonwoven fabric itself, and the appearance of the embossing is adversely affected by density and uneven density.
- the basis weight of the top sheet 1 exceeds the basis weight of the second sheet 4, urine and feces may be retained on the top sheet 1 and the absorption into the absorber 3 may be worsened.
- the weight of the second sheet 4 exceeds 80 gZm 2 , the weight increases and the cost increases. Further, the reason why the thickness and basis weight of the top sheet 1 and the second sheet 4 are simultaneously limited is to balance the appearance of the emboss and the absorbability.
- the convex roll 31 and the concave roll 32 may interfere with each other due to vibration, resulting in abnormal noise and damage to equipment parts. If the clearance exceeds the thickness gauge of the top sheet 1 and the second sheet 4, the embossed pattern does not enter. If the clearance exceeds 3. Omm, embossing is not clearly applied, and the top sheet 1 and the second sheet 4 may not be heat sealed!
- 80 is set so that ⁇ the roll surface temperature of the convex roll 31 ⁇ the roll surface temperature of the concave roll 32 ⁇ 250 ° C. It is preferable to make it. If the roll surface temperature of the convex roll 31 is equal to or higher than the roll surface temperature of the concave roll 32, the convex pattern becomes too clear and hard before the lattice pattern enters.
- the constituent material of the top sheet 1 and the constituent material of the second sheet 4 are the same regardless of the temperature of the roll surface temperature of the convex roll 31 and the concave roll 32. This is because the heat sealing force is increased.
- the identity of the constituent materials refers to the raw materials (for example, made of polyester, polyethylene, etc.), the thickness of the constituent fibers (denier) 'fiber length, the manufacturing method (for example, spunbond, meltblown, etc.). Means broadly the same or not.
- the embossing and the bonding of the top sheet 1 and the second sheet 4 are performed using an embossing roll 40 in which the convex roll 31 is disposed on the upper side and the concave roll 32 is disposed on the lower side, as shown in FIG.
- an embossing roll in which the convex roll 31 is arranged on the lower side and the concave roll 32 is arranged on the upper side
- the top sheet 1 and the second sheet 4 are passed over the convex roll 31 and the concave roll 32 is used.
- embossing roll that is not on the side of the embossing site! /. This is intended to prevent scissors from entering the embossed portion of the top sheet 1 and the second sheet 4.
- the convex roll 31 and the concave roll 32 have the same width as the embossing portion, and as shown in FIG. 7, at least one of the convex roll 31 and the concave roll 32 is placed on the side of the embossing portion.
- Way 31 A In, the diameter can be reduced.
- the top sheet 1 has a property of permeating body fluids such as urine and blood. Therefore, the material of the surface sheet 1 is sufficient if it exhibits this body fluid permeability, and examples thereof include a porous or non-porous nonwoven fabric and a porous plastic sheet.
- the nonwoven fabric is not particularly limited as to what the raw fiber is.
- synthetic fibers such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, regenerated fibers such as rayon cubra, natural fibers such as cotton, and mixed fibers in which two or more of these are used Can be illustrated.

- the Karoe method examples include known methods such as the span-lace method, the spun bond method, the thermal bond method, the melt blown method, and the needle punch method.
- the span-lace method is a preferable Karoe method if the bulkiness and softness are to be obtained.
- the top sheet 1 may be composed of a single sheet or a laminated sheet in which two or more sheets are laminated. Similarly, the top sheet 1 may be composed of one sheet or two or more sheets in the plane direction.
- the back sheet 2 has a property of not transmitting body fluid. Accordingly, the material of the back sheet 2 is sufficient if it exhibits this body fluid impermeability, for example, an olefin-based resin such as polyethylene or polypropylene, a laminated nonwoven fabric laminated with a nonwoven fabric on a polyethylene sheet, or a waterproof film.
- an olefin-based resin such as polyethylene or polypropylene
- a laminated nonwoven fabric laminated with a nonwoven fabric on a polyethylene sheet or a waterproof film.
- a non-woven fabric that is substantially impervious to liquids in this case, the waterproof film and the non-woven fabric constitute the back sheet 2 that is impermeable to bodily fluids.
- materials having liquid-impervious and moisture-permeable properties that have been used and used in recent years from the viewpoint of preventing stuffiness can also be exemplified.
- Examples of the sheet of material having liquid impermeability and moisture permeability include polyethylene and polypropylene.
- Examples thereof include a microporous sheet obtained by kneading an inorganic filler in an olefin-based resin such as the above to form a sheet and then stretching it in a uniaxial or biaxial direction.
- the absorber 3 has the property of absorbing and holding body fluids. Therefore, the material of the absorbent body 3 is sufficient if it exhibits this fluid absorption / retention property.
- publicly known materials such as those having a single pulp strength such as cotton-like pulp and synthetic pulp, and those in which an absorbent polymer made into granular powder or the like is mixed in fluffy pulp can be exemplified.
- the raw material fibers of the pulp are not particularly limited, and examples thereof include cellulose fibers obtained from wood strength such as mechanical pulp, chemical pulp and dissolving pulp, and artificial cellulose fibers such as rayon and acetate. Can do.
- the wood used as the raw material for cellulose fibers is preferable in terms of function and price because conifers have a longer fiber length than hardwoods.
- the absorbent body 3 may be formed of a fiber assembly made of tow such as cellulose acetate, or may be formed of an absorbent material obtained by moving an absorbent polymer into the fiber assembly that also has this tuka. I'll do it.
- the second sheet 4 has the property of diffusing and transmitting body fluid. Therefore, the material of the second sheet 4 is sufficient if it exhibits this body fluid diffusion and permeability, and examples thereof include the same material as the surface sheet 1. However, for example, spunlace, non-woven pulp, mixed sheet of pulp and rayon, point bond or crepe paper are preferred.
- the second sheet 4 has a lower fiber density than the surface sheet 1 which is particularly preferred to be more permeable to body fluids than the surface sheet 1, for example, polypropylene, polyethylene, polyethylene terephthalate, polyamide, nylon, rayon. It is particularly preferable to use a non-woven fabric that is also made of plastic such as vinylon or talyl.
- the encapsulating sheet 5 has a property of transmitting body fluid. Therefore, the same material as exemplified as the top sheet 1 and the second sheet 4 can be exemplified.
