In addition, drying can be in the drying for utilizing heating, the drying using the drying of decompression, combined heated and decompression Any one, also can be natural drying instead of force drying.The hole of filling clad sheet 42 is just fixed as using the drying of heating It is at higher temperature by being heated to more preferably in the range of lossless hemagglutination agent, clad sheet for the viewpoint of the state in portion, Solvent is sharp removed and is subject to drying.

In addition, the clad sheet 42 of the sanitary napkin 1 about present embodiment, is just fixed as the viewpoint of the state in filling pore portion For, according to JIS methods (JIS P8133-1：2013) pH value of the aqueous extract measured is preferably 3.5 or more, and then preferably It is 6.0 or more, and preferably 9.0 hereinafter, be preferably 8.0 in turn hereinafter, furthermore it is preferred that for 3.5 or more and 9.0 hereinafter, in turn Preferably 6.0 or more and 8.0 or less.

In addition, the clad sheet 42 of the sanitary napkin 1 of present embodiment is when moisture penetrates clad sheet 42, hemagglutination agent is molten It solves, the gap in 42 hole portion of clad sheet will increase.This phenomenon is since hemagglutination agent is with the state in filling pore portion Be kept, when moisture is by the hole portion, hemagglutination agent dissolving and from hole portion disappear and generate.That is, thin in blood When hole portion is filled up completely and closes by born of the same parents' agglutinant, sky is generated from void-free state by the dissolving of hemagglutination agent Gap.In addition, the part in the hole portion existing in the form of filled with hemagglutination agent is there are when a little gap, due to this The dissolving of hemagglutination agent and so that the volume in gap is expanded.

In the sanitary napkin 1 of present embodiment, when by maintaining water solubility in the clad sheet 42 for covering absorbent core 41 Hemagglutination agent when menses are by clad sheet 42, be maintained at menses in hole portion by hemagglutination agent when in use Dissolving is made red in the boundary or absorbent core 41 of clad sheet 42 and absorbent core 41 due to the effect of hemagglutination agent Cell agglutination.As a result, agglutinator that menses are separated into red blood cell and the part other than red blood cell, the agglutinator of red blood cell with Part other than red blood cell is compared, mobile to be suppressed, in contrast, the part other than red blood cell is expanded well in absorbent core It dissipates.The part other than the red blood cell of menses is preferentially absorbed into absorber 4 as a result,.Especially, it polymerize using high-absorbable When object, prevent from generating absorption obstruction because accumulating red blood cell on its surface.The part other than the red blood cell of menses becomes more as a result, Reliably with state that the agglutinator of red blood cell detaches and absorbed by superabsorbent polymer, therefore be less also easy to produce because being inhaled in height It absorbs and hinders caused by the surface accumulation red blood cell of the property received polymer.

In the sanitary napkin of present embodiment, by such effect, fully show potential possessed by absorbent core Absorbent properties become the excellent sanitary napkin of absorbent properties.

For more reliably playing the viewpoint of said effect, about clad sheet 42, equably deposited with hemagglutination agent It is that the state of flood is compared, in the skin state more with respect to the amount of surface side, the just more effectively sight in filling pore portion It is preferred for point.It is so-called " more with respect to the amount of surface side in skin ", including hemagglutination agent is in skin opposite face The amount of side is present in skin with respect to surface side with respect to the mode of surface side and hemagglutination agent more than non-skin but is not present in Mode of the non-skin with respect to surface side.

Hole portion in hemagglutination agent by the skin in the hole portion of skin side clad sheet 42a with respect to surface side is filled When, hemagglutination agent is dissolved by the contact with moisture with menses, is flowed out to non-skin opposite face side.Moreover, because menses It is not easy to immerse inside from hole portion to clad sheet, therefore menses are spread on skin opposite face, the moisture in menses and haemocyte The contacting efficiency of agglutinant is got higher.From the state, hemagglutination agent is dissolved in moisture, from skin side clad sheet 42a's The power that skin is moved oppositely facing non-skin opposite face side plays a role strongly, therefore is aggregated block and is formed in various thickness positions It sets, and a part is trapped in clad sheet, a part of absorbability core captures.Therefore, the network of Inter-fiber voids is by office Separate to portion, but in other parts, Inter-fiber voids expansion, therefore is not likely to produce liquid permeability when absorbing repeatedly of menses Obstruction.Further, since clad sheet has the reticulated structure of three-dimensional Inter-fiber voids, therefore dissolve the warp of hemagglutination agent The moisture of blood is not only spread to thickness direction, is also spread to in-plane.In clad sheet, the portion of space part is blocked by agglutination block Divide and is coexisted with the gap section for maintaining hemagglutination agent.Therefore, it is absorbed from the menses at initial stage by after a certain period of time, reaching Hole portion of the menses of clad sheet from increased skin with respect to surface side enters in clad sheet, via the space part of three-dimensional netted construction It can be moved in clad sheet.Moreover, the hemagglutination agent for being maintained at gap section is contacted with menses, and then menses and blood are thin Born of the same parents' agglutinant moves on thickness direction knead dough direction on one side, generates agglutination block on one side and dissolved with the main of hemagglutination agent The fluidity ingredient being made of moisture.By repeating such phenomenon, the sanitary napkin that can absorb menses for a long time can be realized.Separately Outside, when having leakage-proof socket 8 the sanitary napkin 1 such as present embodiment, if by leakage-proof socket 8 and hemagglutination agent configuration section with The mode being overlapped when looking down configures, then the moisture in menses is easy to concentrate on leakage-proof socket 8, to further increase above-mentioned effect Fruit.

In contrast, the present invention also include hemagglutination agent by the non-skin in the hole portion of clad sheet 42 with respect to surface side Hole portion filling the case where.At this point, using such as with above-mentioned hemagglutination agent by the hole of the opposite surface side of the skin of cored part The identical mechanism of mode of portion's filling, can obtain the physiology absorbent commodity for effectively absorbing menses.But in order to obtain The advantageous effects of menses can be absorbed for a long time and steadily from excretion initial stage, preferably hemagglutination agent is by the flesh of cored part Skin is with respect to the mode that the hole portion of surface side is filled.In addition, at least area of the skin with respect to the hole portion of the surface area entirety of surface side 10% or more be the state filled with hemagglutination agent, can more reliably play the effect, therefore preferably.In addition, this Mechanism not necessarily has the hemagglutination agent configuration section containing hemagglutination agent, utilization above-mentioned in excretory portion counterpart B Mechanism can obtain the physiology absorbent commodity that can effectively absorb menses.

A：(trade name " Merquat 100 ", weight average molecular weight 15 is ten thousand) for diallyl dimethyl ammoniumchloride

[table 5]

B：(trade name " Unisense FPA1002L ", weight average molecular weight 60 is ten thousand) for diallyl dimethyl ammoniumchloride

C：Polymethylacrylic acid dimethylaminoethyl diethylester sulfate (trade name " Kaocera MD-P ", Weight-average molecular Measure 5.6 ten thousand)

For the result shown in table 4 and table 5 it is found that in the hemagglutination piece obtained in each test example, high-absorbable is poly- The volume swelling multiplying power for closing object is equally high.In addition, not adding hemagglutination agent and being carried out similarly with test example 1 The volume swelling rate of superabsorbent polymer when evaluation is 12.2 times.In turn, it is known that hemagglutination agent is present in bias Non- skin with respect to surface side hemagglutination piece with hemagglutination agent be present in bias skin with respect to surface side piece compared with, After 2nd time through simulation blood, even if increasing number, the transit dose of 20 seconds simulation blood will not tail off, can take into account The volume swelling multiplying power of superabsorbent polymer.In addition, understanding penetration by liquid in the state of maintaining the uptake of simulation blood It is smaller to measure the degree reduced.

In addition, by each test example it is found that thin with respect to the blood of surface side about making hemagglutination agent be present in skin in bias Born of the same parents' compendency piece, although the transit dose of simulation blood is reduced, the volume swelling of superabsorbent polymer as number increases Multiplying power with so that hemagglutination agent is present in the hemagglutination piece of non-opposite surface side in bias be the good of same degree. That is, illustrating that plasma composition can also pass through hemagglutination piece when such hemagglutination piece is used for sanitary napkin And the superabsorbent polymer of absorbability core fully absorbs.
