2～400g/m
2.Superabsorbent polymer accounts for the quality ratio preferably 30%～65% of the all-mass of the absorbent core consisted of high absorption polymer granule and comminution pulp.
Absorbent main body 4 also can have for preventing the three-dimensional rivel section (not shown) of side leakage in its left side and right side.Can use the about 10g/m of known various fabric nonwoven cloths, for example quality with hydrophobicity or non-liquid permeability for the sheet material that forms three-dimensional rivel section
2～40g/m
2scope in spun bond nonwoven fabric, some adhesion type non-woven fabrics, SMS(spunbonded type meltblown spunbonded type) non-woven fabrics, the plastic foil of non-liquid permeability, the duplexer of above-mentioned material etc.
In the present invention, the part of absorbent core 14 and front waistline member 2 and/or rear waistline member 3 are overlapping.In the embodiment shown in Fig. 1, the place ahead part of absorbent core 14 and front waistline member 2 are overlapping, and the rear part of absorbent core 14 and rear waistline member 3 are overlapping.That is, the two is overlapping for absorbent core 14 and front waistline member 2 and rear waistline member 3, but can be also absorbent core 14 only with front waistline member 2 or rear waistline member 3 in one overlapping.Preferably, absorbent core 14 is at least overlapping with front waistline member 2.
There is compression unit 15 at absorbent core 14.Compression unit 15 is to cross on the line that disposes the nearest waistline elastic component 10a of crotch region under distance or the mode on the extended line of this line exists.And compression unit 15 exists to cross over the two mode of the overlapping zone of absorbent core 14 and front waistline member 2 or rear waistline member 3 and lower crotch region 5.At this, compression unit refers to by compressed thickness that makes such as embossing processing and reduces but the higher part of density.The thickness of compression unit is circumscribed not, is for example 15%～70% of thickness (the not thickness of compressed part) before compressed, and preferably 20%～60%, more preferably 25%～50%.When boil down to be less than thickness before compressed 15% the time, easily cause coating core cladding sheet material and/or the breakage of liquid permeability top-sheet of absorbent core, thereby may cause that the superabsorbent polymer granule is exposed to the bad phenomenon of wearing side.In addition, if the thickness after compression be greater than thickness before compressed 70% the time, can't improve fully the rigidity of absorbent core, be difficult to embody the effect as purpose of the present invention.The width of compression unit is circumscribed not, is for example 0.5mm～10mm, preferably 0.5mm～4mm, more preferably 1.0mm～3.0mm.When width is narrower than 0.5mm, can't improve fully the rigidity of absorbent core, be difficult to embody the effect as purpose of the present invention.In addition, when width is greater than 10mm, owing to comparing with not compressed part, compression unit can hinder absorption (suction) and be excreted to the liquid in absorbent core, therefore when width is wide, can cause becoming the state that body fluid is difficult to promptly be absorbed absorbent core.In the present invention, also exist these compression units to be positioned near urinating the situation of position, as when being difficult to absorbed state, can cause seepage.
Disposable diaper of the present invention is by the separate pull-on disposable diaper that roughly rectangular front waistline member, rear waistline member and absorbent main body form.The advantage of the pull-on disposable diaper of type is like this, due to the materials that can reduce lower limb and enclose, therefore can cut down consumable quantity.The lower limb that disposable diaper of the present invention does not coat the wearer in large area encloses, and owing to can form the state that waistline and lower limb enclose that only coated as required among a small circle, therefore can give succinct outward appearance impression.
But, owing to being structure as follows: the lower limb that makes to be provided in the sidepiece of the waistline elastic component 10a waistline member, that the lower crotch region of distance is nearest and absorbent main body encloses the elastic component quadrature and is obedient to lower limb and encloses complete cycle, therefore make it be obedient to equably columned lower limb and enclose some inadequate (quadrature described herein does not mean the state that the thrum member directly engages each other, and means the state coupled together by ground between the material of elastic component).Specifically, only by the nearest waistline elastic component 10a of the lower crotch region of distance performance, prevent from departing from the effect that lower limb encloses, lower limb encloses elastic component and erects and be obedient to femoribus internus from the side of the absorbent main body let droop, but with prevent from departing from irrelevant.In addition, if distance lower crotch region nearest waistline elastic component 10a departs from, descend the crotch region also can be sagging downwards, thus lower limb enclose elastic component can be not docile.
Because being utilizes the nearest waistline elastic component 10a of the lower crotch region of distance that lower limb is enclosed to the structure that the elastic component hanging gets up to obtain the docile property that lower limb encloses, therefore need the stretching, extension load setting of waistline elastic component 10a that will be nearest apart from lower crotch region must be stronger.Like this, the overlapping part of the waistline elastic component 10a with nearest apart from lower crotch region of absorbent core can be connected to health firmly and can not depart from.
But because of wearer's action, to have to take near the boundary line of waistline member and lower crotch region be that ground is movable before and after boundary to the in-leg area part of not pressed by the waistline member of absorbent core.Particularly the wearer, do and sit down or squat down such when movable, the activity of this part is comparatively remarkable.
As a result, easily cause the absorbent core fracture near the boundary line of waistline member and lower crotch region.If at the veutro fracture, there do not is absorbent core near the organ of urinating, thereby can't absorb at once, easily seepage.If at the dorsal part fracture, near buttocks, there do not is absorbent core, thereby there do not is the rigidity on width, therefore two sides of absorbent main body easily are partial to inboard, and produce problem as follows: for the space of taking in the feces excreted, disappear, buttocks is not coated by diaper and outside being exposed to, and the three-dimensional rivel section that is configured in two lateral margins of absorbent main body embeds wearer's buttocks and produces and wear sense of discomfort.
With regard to disposable diaper of the present invention, have compression unit at absorbent core, compression unit with cross on the line that is equipped with the nearest waistline elastic component of crotch region under distance or on the extended line of this line and the two the mode of absorbent core and front waistline member or the overlapping regional and lower crotch region of rear waistline member of crossing over exist.For non-compression unit, compression unit by paper pulp fiber each other crimping get up to form, and be higher density because also comprising high absorption polymer contained between paper pulp fiber, result, compare with non-compression unit, rigidity is higher.Thereby compression unit can suppress bending.In addition, because compression unit is that crimping forms, therefore be difficult to scatter.In addition, at absorbent core, not only exist comminution pulp also to have the superabsorbent polymer granule, the paper pulp fiber of compression unit can be combined each other more firmly.Therefore, even be ground activity before and after starting point in the situation that cause absorbent core to take the boundary portion of waistline member and lower crotch region because the wearer is movable, the compression unit that rigidity and density are higher also can suppress to form the paper pulp fiber situation separated from one another of absorbent core.Its result, absorbent core can remain indeformable state.
In addition, also there is non-compression unit in boundary portion at waistline member and lower crotch region, at this boundary portion place, with compression unit, compare, the absorbent core of non-compression unit is easily crooked, therefore when the wearer is movable, also can not produce and wear sense of discomfort (the high rigid portion produced because of compression and jointly to be present in boundary portion better because of the not compressed easy bending section produced).Therefore, even, in the situation that the paper pulp weight per unit area of absorbent core is lower, also can improve the problem of distortion, can improve the seepage property wearing effect (if the absorbent core distortion can't utilize this to partially absorb liquid.Particularly veutro is also near the position of urinating, in the situation that distortion has occurred, causes the probability of seepage larger).
Because disposable diaper of the present invention is provided with compression unit in the specific position of absorbent core, therefore the situation of absorbent core fracture can not occur.In addition, even the lower absorbent main body of absorbent core weight per unit area also can be improved the problem of distortion, thereby can improve the seepage property wearing effect.In addition, even the lower slim absorbent core of paper pulp weight per unit area also can improve the problem of distortion, thereby can improve the seepage property wearing effect.In addition, due to the zone that also forms the parallel performance of effect that makes absorbent properties and prevent the distortion at lower crotch region, therefore can further improve seepage property.When embodying identical seepage property, can also reduce the paper pulp weight per unit area, the absorbent core that the paper pulp weight per unit area is lower can reduce costs.In addition, such activity even the wearer is stood, sits down, absorbent core can not be out of shape yet, and can prevent that absorbent core is outstanding to the direction of leaving wearer's body in wearing process.Its result, even also can keep succinct outward appearance after absorbing liquid.
Compression unit so long as with cross on the line that is equipped with the nearest waistline elastic component of crotch region under distance or on the extended line of this line and the two the mode of absorbent core and front waistline member or the overlapping zone of rear waistline member and lower crotch region of crossing over exist and get final product, it can configure in any way under this restrictive condition.Fig. 3～Figure 11 means the example of the configuration mode of compression unit.Disposable diaper of the present invention has the waistline elastic component and lower limb encloses elastic component, but in Fig. 3～Figure 11, for the ease of the mode of the configuration of observing compression unit, has omitted the diagram that waistline elastic component and lower limb enclose elastic component.
In a preferred embodiment, as shown in Figure 1, there is at least one compression unit 15 in the right side of absorbent core, have at least one compression unit 15 in the left side of absorbent core, at the left and right directions central part of absorbent core, have at least one compression unit 15.When wearer's walking, absorbent core is stressed from the left and right sides, and ground about absorbent core is moved.By for this power, at two sidepieces and the central part of absorbent core, compression unit being set, can form the skeleton that is difficult to distortion, even because wearer's ambulatory activities causes ground, absorbent core left and right mobile, absorbent core also is difficult to distortion.
And preferably, the compression unit that at least is positioned at right side and left side intersects with the waistline elastic component 10a nearest apart from lower crotch region as shown in Figure 1.By the nearest waistline elastic component 10a of compression unit 15 and the lower crotch region of distance is intersected, can make absorbent core 14 become and more be difficult to distortion.
In another embodiment, there is the compression unit extended along left and right directions X in the fore-and-aft direction central part at lower crotch region.The fore-and-aft direction middle section of lower crotch region is by the position of wearer's lower limb clamping, therefore absorber easily is partial to the width central part, easily make the width of absorber become narrower state, but employing said structure, absorber is difficult to be partial to width, can keep the width of the middle section of the fore-and-aft direction at lower crotch region of absorber.Particularly can keep the width by the part of buttocks side.
