(2) structure of absorber
Secondly, the structure for absorber is described in detail.Absorber comprises the thin paper of absorbent cores containing paper pulp and superabsorbent polymer and parcel absorbent cores.Thin paper comprises the upper strata thin paper of the skin surface side being configured in absorbent cores and is configured in lower floor's thin paper of side, non-skin face.In addition, in the accompanying drawings, for convenience's sake, thin paper is eliminated.
The absorbent cores of present embodiment includes the paper pulp of weight per unit area 254.4g/m2, the superabsorbent polymer of weight per unit area 228.3g/m2.Superabsorbent polymer is 47% relative to the ratio of the absorbing material of absorbent cores entirety.In addition, preferably, superabsorbent polymer is 35 ~ 55% relative to the ratio of the absorbing material of absorbent cores entirety.The area of absorber is 460cm2.In addition, the weight per unit area of upper strata thin paper is 18g/m2, and the weight per unit area of lower floor's thin paper is 16g/m2.
When absorber 30 is divided into skin side region 30A, middle section 30B and non-skin side region 30C along its thickness direction, middle section 30B is compared with skin side region 30A and non-skin side region 30C, and the density of superabsorbent polymer uprises.Fig. 3 is the enlarged drawing of the part B shown in Fig. 2.In figure 3, the roughly zoning of skin side region 30A, middle section 30B and non-skin side region 30C is indicated.
In addition, skin side region 30A be the contact skin side comprising absorber 30 face and from the certain region facing to non-skin contact side of contact skin side.Non-skin side region 30C be the non-skin contact side comprising absorber face and from the certain region facing to skin contact side of this non-skin contact side.Middle section 30B is the region between skin side region and non-skin side region.
Skin side region, middle section and non-skin side region are folded with above-mentioned sequential layer in the thickness directiont.Such as, the thickness in skin side region is 10% ~ 40% of the thickness of absorber, and the thickness of middle section is 20% ~ 80% of absorbed thickness, and the thickness of non-skin side region is 10% ~ 40% of the thickness of absorber.
As the absorber that the thickness of middle section is the thinnest, the thickness in skin side region is 40%, and the thickness of middle section is 20%, and the thickness of non-skin side region is 40%.In addition, the thin absorber that the thickness as middle section is the thickest, the thickness in skin side region is 10%, and the thickness of middle section is 80%, and the thickness of non-skin side region is 10%.The thickness of the skin side region of absorber, middle section and non-skin side region suitably can set in the scope of these absorbers.
Also the thickness in the Thickness Ratio skin side region of non-skin side region can be made thick.Superabsorbent polymer is granular, when the transport of disposable diaper or the time of wearing, moves, move to the back sheet side of absorber in the gap sometimes between paper pulp.If superabsorbent polymer moves to the back sheet side of absorber, then sometimes the outside of disposable diaper face (being configured with the face of back side adhesive-bonded fabric 21) produce by superabsorbent polymer cause coarse, the people's (such as, changing the people of disposable diaper) carrying out dressing can touch hard superabsorbent polymer.But, thick by the thickness in the Thickness Ratio skin side region making non-skin side region, can suppress on the face in the outside of disposable diaper by superabsorbent polymer cause coarse.
In addition, the thickness that also can be configured to the Thickness Ratio non-skin side region in skin side region is thick.The National People's Congress carrying out dressing touches the face in the outside of disposable diaper more, but wearer contacts the face (face of surface patch side) of the inner side of disposable diaper mostly.Thick by the thickness of the Thickness Ratio non-skin side region making skin side region, that the superabsorbent polymer on the face of the inner side of disposable diaper can be suppressed to cause is coarse, improves the impression of carrying out dressing.
Preferably, the thickness of absorber 30 is at below 5.0mm.By being thickeied by the thickness of absorber 30, the resiliency of absorber 30 can be improved.But, when the thickness of undue thickening absorber 30, be difficult to the shape being kept absorber entirety in a thickness direction below by the press section described.Thus, preferably, the thickness of absorber is at below 5.0mm.In addition, the thickness of the absorber of present embodiment is 3.0mm, and the degree of depth of the press section described below is 1.2mm.
In addition, the thickness of absorber mentioned here is the thickness under the surface patch, side sheet 60 etc. making elastic component such as leg surrounding elastomeric material 25 grade be stretched to formation disposable diaper does not form the state (state shown in Fig. 1) of gauffer.
In addition, the respective thickness of skin side region, middle section and non-skin side region, such as, can after being impregnated in liquid nitrogen and making it to freeze, cut off with razor, after turning back to room temperature, measure under the amplification of 50 times with ultramicroscope (such as, キ-エ Application ス company VE7800).
Skin side region, middle section and non-skin side region can utilize each layer to form discretely, also can make it integration.Such as, in the fabrication process, other manufacture technics skin side region, middle section and non-skin side region can be utilized, under the state be manufactured into, by skin side region, middle section and the integration of non-skin side region.
In addition, as long as the density of the superabsorbent polymer of middle section is formed than the density highland of the superabsorbent polymer of skin side region and non-skin side region, can superabsorbent polymer be configured in skin side region and non-skin side region, also can be unworthy of setting high absorbable polymer.
In addition, the so-called concept being unworthy of the structure setting high absorbable polymer in skin side and non-skin side, be also included within the structure being unworthy of setting high absorbable polymer in manufacture process in skin side and non-skin side, and be after the fabrication process (such as, medium at goods course of conveying), move to skin side region and non-skin side region by a part for superabsorbent polymer and in the structure of skin side region and non-skin side region configuration superabsorbent polymer.
When the middle section of absorber is made up of paper pulp and superabsorbent polymer, such as, the density of the superabsorbent polymer of middle section can be made to be 0.14g/cm3.When the middle section of absorber is made up of with the sheet material clipping superabsorbent polymer superabsorbent polymer, such as, can make the ratio of the superabsorbent polymer of middle section more than 80%.
The density of the respective superabsorbent polymer of skin side region, middle section and non-skin side region such as can utilize following method to measure.
When under the dry state of absorber skin side region, middle section, non-skin side region being separated, absorber known for area is separated into skin side region, middle section, non-skin side region, measures the respective thickness of skin side region, middle section, non-skin side region.The thickness of each skin side region, middle section, non-skin side region can utilize ultramicroscope (such as, キ-エ Application ス company VE7800) to measure.Secondly, respectively skin side region, middle section, non-skin side region are enclosed in bag respectively, vibrate tens times to each bag of major general, by superabsorbent polymer from skin side region, middle section, non-skin side region be separated.Then, take out skin side region, middle section, non-skin side region, utilize tweezers to take out indissociable superabsorbent polymer.Superabsorbent polymer in bag is combined with the superabsorbent polymer utilizing tweezers to take out and measures its weight.Further, the density of superabsorbent polymer of skin side region, middle section, non-skin side region can be calculated.
On the other hand, when skin side region, middle section, non-skin side region not being separated under the dry state of absorber, the weight of the known absorber of area is measured.Secondly, absorber to be impregnated in the ion exchange water of the q.s utilizing water-soluble dye painted 5 minutes.After dipping, using the interface of the high water absorbency polymer of swelling as release surface, tweezers are utilized to be peeled off from absorber in the skin side region of absorber and take out.Using the part of taking-up as skin side region, utilize the electric drying apparatus drying more than 1 hour of 80 DEG C.Utilize tweezers etc. to be attached to the high water absorbency polymer be colored in dried skin side region from skin side region disconnecting, they are concentrated and measures its weight, using the weight of this weight as the water absorbent polymer in skin side region.Similarly, the weight of the superabsorbent polymer of non-skin side region is measured.
The thickness of each skin side region, middle section, non-skin side region, utilizes ultramicroscope (such as, キ-エ Application ス company VE7800) to measure in advance.At this moment, the interface of skin side region, middle section, non-skin side region becomes the boundary (boundary when utilizing tweezers to peel off) of the many parts of high water absorbency polymer and few part, as long as the interface of skin side region, non-skin side region and middle section is in the scope of 10-40% from whole skin side, non-skin side.
The middle section of absorber is formed with the density ratio skin side region of superabsorbent polymer and the high mode of non-skin side region, and the density ratio middle section of the superabsorbent polymer of skin side region and non-skin side region is low.The skin side region of absorber and non-skin side region are easy and the part of the contact skin of wearer, if the weight per unit area of the superabsorbent polymer of this part is high, then wearing feeling is by more easily worsening.But, due to easily and the skin side region of contact skin of wearer and the weight per unit area of the superabsorbent polymer of non-skin side region low, so, the deterioration that the coarse grade that caused by superabsorbent polymer and wearing feeling are subject to can be suppressed.
In addition, in order to by absorber slimming, it is contemplated that the ratio improving superabsorbent polymer in order to ensure absorbent properties relative to all absorbing materials forming absorber.But, when improving superabsorbent polymer relative to the ratio of all absorbing materials forming absorber, also existing and producing in absorber surface the worry that coarse, the skin feel that are caused by superabsorbent polymer worsen.But, by reducing the weight per unit area of the superabsorbent polymer in skin side region and non-skin side region, even if when by absorber slimming, also can guarantee absorbent properties by the superabsorbent polymer of middle section, and the deterioration that is subject to by the coarse wearing feeling caused of the superabsorbent polymer of absorber surface can be suppressed.
In addition, such as, when improving the weight per unit area of superabsorbent polymer in skin side region, also exist by absorbing body fluid by the superabsorbent polymer in skin side region, and produce gel blockage, worry that the absorbent properties of whole absorber worsen.But, by improving the weight per unit area of the superabsorbent polymer of middle section, the generation of gel blockage can be suppressed.
On absorber 30, be formed with multiple press section that have compressed absorber in a thickness direction.Press section comprises: be formed in the skin contact side of absorber and the face side recess 31 be recessed into from surface patch side direction back sheet side and the back sheet side that is formed in absorber and the rear side recess 32 recessed from back sheet lateral surface sheet side.Compressed absorbent and form press section is in the thickness directiont processed by embossing.
Face side recess 31 by from interior side direction T1 outward direction T2 compress, from interior side direction outward direction be recessed into.On the face of the contact skin side of absorbent commodity, be formed with the recess that the face side recess 31 along absorber 30 configures.By forming this recess along the face side recess 31 allocation list dough sheet 10 of absorber 30 and intermediate 15.
In addition, rear side recess 32 is compressed from foreign side direction T2 inside side direction T1, and from foreign side direction, inside side direction is recessed into.On the face of the non-skin contact side of absorbent commodity, be formed with the recess that the rear side recess 32 along absorber 30 configures.By configuring back side adhesive-bonded fabric 21 and back side film 22 along the rear side recess 32 of absorber 30 and forming this recess.
Secondly, the shape for the press section formed on the absorbent body is described.Fig. 4 is the enlarged drawing of the part A shown in Fig. 1.In addition, due in plan view, the shape of the face side recess 31 of present embodiment and the shape of rear side recess 32 are identical shapes, so, in the following description, be described as an example with the shape of face side recess 31.
In addition, be not limited to the structure that the shape of face side recess 31 is identical with the shape of rear side recess 32, the shape of face side recess 31 and the shape of rear side recess 32 also can be different.And then, as long as press section has at least one party in face side recess 31 and rear side recess 32.
Face side recess 31 comprises: the first press section 33 extended on the first incline direction C1 that the length direction and width with absorbent commodity intersects and intersecting with the first incline direction C1 and the second press section 34 that the second incline direction C2 intersected with length direction and width extends.
First press section 33 and the direction of the second press section 34 alongst and in width, namely alternately arrange formation as the length direction L of first direction, alternately formed at spaced intervals along the width W as the second direction orthogonal with first direction.Thus, on the absorbent body, the wavy wire press section 35 of multiple continuous print is in the longitudinal direction formed.Wire press section 35 is made up of the first press section 33 alongst alternately arranged and the second press section 34.
Region between the first adjacent in the longitudinal direction press section 33 and the second press section 34 and the region between the first adjacent in the direction of the width press section 33 and the second press section 34, be provided with the non-crush-zone R1 not forming press section.
First press section 33 length L33 in the longitudinal direction, longer than the first press section 33 length W33 in the direction of the width, the second press section 34 length L34 is in the longitudinal direction longer than the second press section length W34 in the direction of the width.Thus, the shape of non-crush-zone R1 is that size on length direction is longer than the size on width.In addition, the shape in the plan view of non-crush-zone R1 is rhombus.
Preferably, the width T33 of the first press section and the width T34 of the second press section is at more than 1mm.By the width T34 of the width T34 and the second press section that make the first press section at more than 1mm, the first press section 33 and the second press section 34 can be utilized to extrude absorber 30 in a thickness direction.In addition, when the width T33 of the first press section 33 and width T34 of the second press section becomes long, sometimes, the first press section 33 and the second press section 34 can become really up to the mark.Thus, preferably, the width W 31 of the first press section and the width W 32 of the second press section are at below 3.0mm.
Owing to being formed with press section on the absorbent body, so, the movement of the superabsorbent polymer in press section decrease uptake body can be utilized, suppress due to superabsorbent polymer secund configure and the wearing feeling that causes by and the deterioration of absorbent properties.
And then, because the first press section 33 is along the first incline direction, the second press section 34 is along the second incline direction C2, and the first press section 33 and the second press section alternately configure, so, the non-crush-zone R1 be surrounded in four directions by the first press section and the second press section can be set.Owing to forming multiple non-crush-zone R1, so, moderately can divide the scope of superabsorbent polymer movement, the secund of superabsorbent polymer can be suppressed.
In addition, arrange on length direction and width at the first press section 33 and the second press section 34 and do not arrange in the structure in gap between the first press section 33 and the second press section 34, the first press section 33 and the second press section 34 form the part of intersection on length direction and width.Due to the part of intersecting for the first press section and the second press section, absorber is compressed in a thickness direction, therefore, hardening compared with surrounding.If at the partial configuration superabsorbent polymer that this first press section and the second press section intersect, then hardening further, there is the worry of the sense of discomfort grow of wearer.
But, the first press section and the second press section is spaced apart in the direction of the width alternately configures.Thus, when forming press section, the space that superabsorbent polymer is kept out of the way can be set, suppress the sclerosis of the local of the absorber caused due to concentrating of superabsorbent polymer, the deterioration that wearing feeling is subject to can be suppressed.
In addition, on the absorbent body, multiple non-crush-zone is provided with.Such as, when the whole face of absorber is in a thickness direction by compression, because the fiber forming the paper pulp of absorber etc. is compressed, so the resiliency of absorber reduces.But, owing to being formed with multiple non-crush-zone R1 between the press section of absorber, so, can resiliency be guaranteed.In addition, guarantee resiliency to obtain and utilize press section to push the effect of absorbing material, preferably, the area of press section is 200 ~ 600mm2.
Face side recess 31 is compressed by the contact skin side direction non-skin contact side from absorber in a thickness direction.Because face side recess 31 is compressed, so the fibre density in the region of the skin contact side of absorber uprises by the contact skin side direction non-skin contact side from absorber in a thickness direction.Thus, the resiliency touching the contact skin side of the skin of wearer of absorber is high, and skin feel improves.In addition, uprised by the fibre density in the region of the skin contact side of absorber, fiber winding is each other reinforced, and the diffusibility of body fluid improves.And then, be reinforced by fiber winding each other, superabsorbent polymer can be suppressed to the movement of skin contact side.
And then, rear side recess 32 in a thickness direction by the non-skin contact side from absorber to contact skin side compression.Due to rear side recess 32 in a thickness direction by the non-skin contact side from absorber to contact skin side compression, so the fibre density in the region of the non-skin contact surface side of absorber uprises.Thus, the wearer of absorber is easy to the resiliency raising of the non-skin contact surface side contacted, and skin feel improves.In addition, uprised by the fibre density in the region of the skin contact side of absorber, fiber winding is each other reinforced, and the diffusibility of body fluid improves.And then, be reinforced by fiber winding each other, superabsorbent polymer can be suppressed to the movement of non-skin contact surface side.In addition, by forming face side recess 31 and rear side recess 32, the fiber of the fiber of the skin surface side of absorber and side, non-skin face can be wound around securely.
And then, to be improved by the resiliency of the skin contact side of absorber and non-skin contact surface side, though in slimming, also can suppress the generation of sense of discomfort.
First press section and the second press section interval T 36 in the direction of the width at more than 0.35mm, and at below 8.5mm.0,35mm is the mean diameter of superabsorbent polymer.When the first press section and the second press section interval in the direction of the width less than the particle diameter of superabsorbent polymer time, superabsorbent polymer does not pass through between the first adjacent in the direction of the width press section and the second press section, and between the first press section and the second press section, produce the part that superabsorbent polymer solidifies.Because the rigidity of superabsorbent polymer is higher than paper pulp, so when superabsorbent polymer forms the part of solidifying, this part is hardening partly, there is the worry that wearing feeling is worsened.But, by make the first press section and the second press section in the direction of the width between be interposed between more than 0.35mm, form the space that superabsorbent polymer passes through between first press section that can adjoin in the direction of the width and the second press section.
Such as, when the first press section and the second press section consecutive hours in the direction of the width, press section is configured to latticed.On the absorbent body, formed multiple four sides by a pair first press sections and a pair second press section surround space.The region that squeezed splenium like this surrounds, is not the space that superabsorbent polymer passes through, can produces the intensive of superabsorbent polymer, there is the worry forming the high part in rigidity local.But, by forming the space that superabsorbent polymer passes through between the first adjacent in the direction of the width press section and the second press section, the sclerosis of local can be suppressed.
In addition, the first press section 33 and the second press section 34 interval T 36 are in the direction of the width at below 8.5mm, and more preferably, interval T 36 is at below 4.25mm.Specifically, preferably, being the half of the width outboard end of the first press section adjacent in the direction of the width and the distance W36 of the second width outboard end, more preferably, is 1/4 of distance W36.
Roughly whole absorber forms press section, and by forming press section, the flexural rigidity of absorber uprises.Thus, under absorber such as have been pushed at the situation inside lateral width in the width direction, even if when power has been applied on absorber outside, also wrinkle have been not easy.But, when the first press section and the second press section interval in the direction of the width longer than 8.5mm time, the region not forming press section is elongated, and the effect of absorber wrinkle that prevents produced by press section reduces.Thus, from the view point of the wrinkle preventing absorber, preferably, the first press section and the second press section in the direction of the width between be interposed between below 8.5mm.And then, when the first press section and the second press section in the direction of the width between be interposed between below 4.25mm time, can the wrinkle of decrease uptake body effectively.
Because press section is formed on whole of absorber, so, whole of absorber is suppressed the movement of superabsorbent polymer, can suppress by absorbability macromolecular material secund configure and the wearing feeling that causes by and the deterioration of absorbent properties.And then, owing to forming press section on whole of absorber, so body fluid spreads on whole absorber, can gel blockage be suppressed.And then, the absorptive capacity of absorber can be effectively utilized.
In addition, when will by absorber slimming time, in order to ensure absorbent properties, consider to improve superabsorbent polymer relative to the ratio of whole absorbing materials forming absorber.But when improving superabsorbent polymer relative to the ratio of whole absorbing materials forming absorber, because the ratio of paper pulp reduces, therefore, paper pulp adhesion each other reduces, and absorber becomes easy wrinkle.But, by forming press section on the whole region of absorber, even if when by absorber slimming, also can wrinkle be suppressed.
The absorber of present embodiment forms press section at whole.But, also can not form press section on whole.Such as, also only press section can be formed being configured on the absorber in the crotch area S2 comprising the scavenge port contact area contacted with the scavenge port of wearer.By partly forming press section not on whole of absorber, the rigidity of absorber entirety can be reduced, improving flexibility.
First press section 33 and the consecutive wire press section 35 of the second press section 34, alongst configure.Usually, the length in the length: width direction of the length direction of absorber 30 is long, there is the worry at the length direction both ends that effectively can not use absorber.But, by arranging the first press section 33 and the second press section on the length direction of absorber continuously, body fluid can be made to spread in the longitudinal direction, effectively using the whole region of absorber.
In addition, the first press section 33 and the second press section 34 are the diamond shape of size than the size length of width of length direction.When applying power inside the width lateral width of absorber, formed in the mode that this power is alongst transmitted.Specifically, when the first press section 33 and the second press section 34 size in the direction of the width compare size length in the longitudinal direction, sometimes, suppress the power of being out of shape to become in the direction of the width than strong in the longitudinal direction by press section, absorber is difficult to be out of shape inside width.But, when by press section suppress distortion power become in the direction of the width than weak in the longitudinal direction, such as by wearer lower limb clamp, absorber can be made flexibly to be out of shape.
