Can in the time making the nonwoven of using on top layer, blood modification agent be coated to nonwoven. In addition, also canBlood modification agent is coated to top layer 2 in the manufacturing process of absorbent commodity 1. But, establish from inhibitionThe viewpoint of standby investment is considered, preferably, in the manufacturing process of absorbent commodity 1, blood modification agent is coated withIn top layer 2. In addition, during being suppressed at the manufacturing process of absorbent commodity 1, coat top layer 2Blood modification agent reduces, and preferably in the operation completing that approaches absorbent commodity 1, blood modification agent is coated withBe distributed in top layer 2. For example can, before being about to the operation of packaging absorbent commodity 1, blood modification agent be coated withBe distributed in top layer 2.
Fig. 5 is in order to pack bending the has been described figure of absorbent commodity 1 of alar part 6. Packaging hasIn the situation of the absorbent commodity 1 of above technical characterictic, as shown in Figure 5 a pair of alar part 6 bendings are arrived wideDegree direction inner side.
Bonding part 7 is stripped from sheet material 33 and covers. Thus, can protect sticky before the use of absorbent commodity 1Close portion 7. If the sheet material that releasing sheet 33 can be peeled off for the adhesive of bonding part 7 is not special limitFixed. Releasing sheet 33 for example can use remover is coated to the releasing sheet that base material forms.

Fig. 7 is the schematic cross-section in the D-D line cross section of presentation graphs 5. As shown in Figure 7, when bending alar part 6Sidepiece sheet 5 in alar part 6 contacts with the blood modification agent dispensing area 18 (with reference to Fig. 1) on top layer 2. Due toBlood modification agent dispensing area 18 is coated with blood modification agent, and therefore, the top layer 2 in alar part 6 changes with bloodMatter agent contact. But by the teat 21 on top layer 2, the sidepiece sheet 5 in alar part 6 changes with the blood on top layer 2The contact area of matter agent dispensing area 18 reduces. Thus, can suppress blood modification agent dispensing area 18Blood modification agent is infiltrated up to alar part 6 and engaging force between top layer 2 and bottom 3 in alar part 6 dies down. SeparatelyThe blood modification agent that can suppress blood modification agent dispensing area 18 outward, is transferred to the sidepiece sheet 5 of alar part 6And the amount of the blood modification agent of blood modification agent dispensing area 18 reduces.
As mentioned above, the fibre density of the central portion 23 of teat 21 is lower than the sidepiece 24 of teat 21 and/or recessedThe fibre density (with reference to Fig. 3) of portion 22. And coat the blood of the blood modification agent dispensing area 18 on top layer 2, there is the tendency of assembling to the fibre density eminence on top layer 2 in modification agent. In top layer 2, contact with alar part 6The fibre density of central portion 23 of teat 21 lower than the sidepiece of teat 21 and recess 22, therefore, at teat21 central portion 23 can not assembled too many blood modification agent. Therefore, by with the sidepiece 24 of teat 21 and/Or the fibre density of recess 22 compares, reduce the fibre density of the central portion 23 of teat 21, can be furtherReduce the amount of the blood modification agent that is transferred to alar part 6.
The absorbent commodity 1 of above one embodiment of the present invention can as described belowly be out of shape.
(1) top layer 2A that can be is as shown in Figure 8 such, forms peristome 26A at the recess 22A of top layer 2A.Fig. 8 (a) for to amplify by the teat, recess and the peristome that are formed at top layer 2 stereogram forming, Fig. 8's(b) for the teat, recess and the peristome that are formed at top layer 2 are amplified to the top view forming. Peristome 26AThe fibre density of side is preferably higher than the fibre density of the central portion 23A of teat 21A. Thus, coatThe blood modification agent on top layer be mostly gathered in be formed at recess 22A peristome 26A around, therefore,Central portion 23 at the teat 21 contacting with alar part 6 can not assembled too many blood modification agent. Therefore, logicalCross the fibre density that makes peristome 26A side higher than the fibre density of the central portion 23A of teat 21A, canThe amount of the blood modification agent that is transferred to alar part 6 during with minimizing bending alar part 6. Thus, can suppress due toThe blood modification agent of coating top layer 2A is infiltrated up to alar part 6 and the sidepiece sheet 5 that forms alar part 6 is shelled by bottom 3From.
For example as shown in Figure 9, by will width (CD) extend, operating direction (MD) arrange,Multiple elongate members 160 without gas permeability are arranged at netted supporting member 130, can be at top layer 2ARecess 22A form peristome 26A. At netted supporting member 130 elongate member 160 is not setPart, the gas 141 being sprayed by blowing unit 140 is by netted supporting member 130, therefore with can beKnitting the degree that sheet 120 forms chase 122 pushes the fiber of knitting sheet 120 aside. On the other hand, netted supporting structureThe part that is provided with elongate member 160 of part 130, the gas 141 being sprayed by blowing unit 140 does not pass through netShape supporting member 130, is stopped by elongate member 160, therefore, knits the fiber of sheet 120 knittingSheet 120 forms the degree of peristome and is pushed aside forcefully. Thus, form at the recess 22A of top layer 2APeristome 26A. The fiber of being pushed aside is intensive in peristome 26A side, the therefore fibre of peristome 26A sideDimension density raises.
(2) top layer 2B that can be is as shown in figure 10 such, by by the nonwoven that forms top layer 2B with wavyBending, top layer 2B be formed on prescribed direction extend, at the teat of the direction arrangement intersecting with prescribed direction21B and recess 22B. Figure 10 is the schematic perspective view of the variation on top layer. For example pass through at a pair of gearBetween roller by nonwoven, the top layer 2B that can make with wavy bending. In addition, also can be as Figure 11Shown in, be formed with top layer 2C recessed of teat 21C and recess 22C with wavy bending by nonwovenThe 22C of portion forms peristome 26C.
The schematic perspective view of the variation that (a) of Figure 11 is top layer, what (b) of Figure 11 was the variation on top layer bowsDepending on schematic diagram. For example there are the multiple of the shapes such as needle-like, drum and cone shape on the surface of peripheryThe projection roller of projection, has with projection chimeric with the surface of periphery in the position of the projection corresponding to projection rollerThe backing roll (anvilroll) of recess between, by the nonwoven with wavy bending, can make thusBe formed with the top layer of peristome 26C at recess 22C. Connecting nonwoven by the projection of projection roller formsPeristome 26C, therefore, while forming peristome 26C, exerts pressure to peristome 26C side. Therefore,Rising compared with the fibre density of the fibre density of peristome 26C side and the central portion 23C of teat 21C. CauseThis, the blood modification agent of coating top layer 2C is gathered in the peristome 26C side of the recess 22C of top layer 2C,The amount of the blood modification agent that is transferred to alar part 6 therefore can reduce bending alar part 6 time. Thus, can press downSystem is infiltrated up to sidepiece sheet 5 that alar part 6 forms alar part 6 end of by owing to coating the blood modification agent of top layer 2CLayer 3 is peeled off.
(3) can be as shown in figure 12, by being arrived by top layer 2D the compression unit 8D of the inside of absorber 4DBe formed at absorbent commodity 1D, the alar part 6 while reducing bending alar part 6 is coated with the blood modification agent on top layer 2Contact area between region 18. Figure 12 is the cross section corresponding to the absorbent commodity 1D of the A-A line of Fig. 1Schematic diagram. Thus, when bending alar part 6, can reduce by the blood modification agent dispensing area 18 on top layer 2 and turnPrint to the amount of the blood modification agent of alar part 6. The compression unit 8D that is formed at absorbent commodity 1D can be wireCompression unit or the compression unit of point-like. Compression unit 8D for example can process to be formed at absorbability by embossingArticle 1D.
Compression unit 8D forms at thickness direction compression top layer 2D and absorber 4D, therefore compression unit 8DNear top layer 2D bottom and the density of absorber 4D raise. Therefore the blood of, coating top layer 2D changesMatter agent is assembled to the bottom direction of compression unit 8D, therefore, when bending alar part 6, can further reduce byThe blood modification agent dispensing area 18 on top layer 2 is transferred to the amount of the blood modification agent of alar part 6. Thus, canSuppress due to coat the blood modification agent of top layer 2D be infiltrated up to sidepiece sheet 5 that alar part 6 forms alar part 6 byBottom 3 is peeled off. It should be noted that, while forming compression unit 8D, if the top layer 2D filming of compression unit 8DBlood modification agent can not be infiltrated up to top layer 2D, therefore, and the not film of top layer 2D in the 8D of preferred compressed portionChange.
(4) if can reduce the contact area between blood modification agent dispensing area 18 and the alar part 6 on top layer 2,The teat that is formed at the blood modification agent dispensing area 18 on top layer 2 is not limited to above-mentioned teat. For example canThe blood modification agent dispensing area 18 on top layer 2 be arranged on width (directions X) extend, at length directionThe teat that (Y-direction) arranges. In addition, also can the blood modification agent dispensing area 18 on top layer 2 arrange withWavy form is at the teat of length direction (Y-direction) or width (directions X) extension. And then can beThe blood modification agent dispensing area 18 on top layer 2 arranges the teat of the shapes such as cylinder, prism, hemisphere.
(5) in order further to reduce contacting between the blood modification agent dispensing area 18 on top layer 2 and alar part 6Area, can form teat at sidepiece sheet 5. Absorbent commodity 1E that for example can be is as shown in figure 13 such,At sidepiece sheet 5E, the teat 51 extending at length direction by forming with wavy bending is set. Figure 13For the schematic cross-section of the absorbent commodity 1E of the A-A line corresponding to Fig. 1. The blood that is formed at top layer 2 changesThe teat of matter agent dispensing area 18 is not limited to above-mentioned teat. It should be noted that, also can establish at sidepiece sheetPut the teat extending at width. In addition, also can arrange with wavy form in length at sidepiece sheetThe teat that direction or width extend. And then the shapes such as cylinder, prism, hemisphere can be set at sidepiece sheetThe teat of shape.
(6) composition that the composition on top layer is regulation if coat, is not limited to blood modification agent. For exampleCan will prevent that the coarse lotion of skin from coating top layer.
