Description of the Invention: [Technical Field] The present invention relates to an absorbent article such as menstrual sanitary napkins, sanitary pads, etc. [Prior Art] As a menstrual sanitary napkin having excellent functions of menstrual blood not leaking, Patent Document 1 describes a sanitary napkin in which a compressed strip-shaped groove is provided in a lattice pattern on the upper surface of the absorbing portion. Indeed, in the sanitary napkin of the medlar period described in the patent document, the compressed strip-shaped groove is formed in a grid pattern, so that the menstrual blood is difficult to spread on the surface, and the menstrual blood is not easily leaked, but it is described in the patent document. In the menstrual sanitary napkin, the so-called second sheet is not disposed, so it is difficult to instantaneously absorb the gold through the surface of the menstrual napkin. For example, Patent Document 2 describes a relatively thin menstrual period in which a water-jet non-woven fabric sheet containing rayon and polyester fibers is disposed between the top sheet and the absorbent core to obtain a sheet. Sanitary cotton. Further, in Patent Document 3, it is described that the sheet is disposed between the sheet after liquid permeability and the liquid impermeability, and the body sheet is disposed on the upper sheet side and the back sheet side is disposed. An absorbent article comprising an absorbent core of a liquid storage layer, wherein the body-capture distribution layer is a % cotton web formed of hydrophilic cellulose fibers obtained by hardening wood pulp fibers with an interfiber chemical stiffener. Indeed, since the menstrual sanitary napkin of Patent Document 2 is provided with a so-called disc member, that is, a liquid permeable wipe to obtain a sheet, the body fluid can be dispersed in the lateral direction and the top sheet of the sanitary napkin can be instantaneously Absorbed blood by 156335.doc 201143727. However, since the liquid permeable smear obtained by the menstrual sanitary napkin of Patent Document 2 contains the rayon which is a semi-synthetic fiber, liquid liquid which is liable to generate body fluid remains, and it is difficult to wipe the body fluid from the liquid permeability to obtain a sheet. The material is transferred to the absorbent core, so it takes time to completely transfer the body fluid to the absorbent core. Further, since the absorbent article of Patent Document 3 is provided with a body-catching distribution layer as a so-called second sheet, the body fluid can be quickly collected and temporarily held, and the sheet above the self-absorbable article can be instantaneously Absorb body fluids. However, since the body-capture distribution layer of the absorbent article of Patent Document 3 is a cotton web formed of hydrophilic cellulose fibers, the body fluid is maintained, and similar to the menstrual sanitary napkin of Patent Document 2, body fluid is easily generated. The liquid remains 'and it takes time to transfer the body fluid body capture distribution layer to the liquid storage layer. Patent Document 1: Japanese Patent Laid-Open Publication No. SHO 56-109660 Patent Document 2: US 4950264A Patent Document 3: US 5217445A SUMMARY OF THE INVENTION Accordingly, the present invention is directed to providing a body fluid which is difficult to spread on a surface and which can reduce an absorbent body. An absorbent article in which a liquid other than the body fluid remains, and the time during which the body fluid is transferred to the absorbent body is shortened. The present invention includes a front sheet disposed on the skin contact surface side, a back sheet disposed on the non-skin contact surface side, an absorbent member disposed between the sheets, and the absorbent sheet and the front sheet disposed thereon An absorbent article of the second sheet between. In the above absorbent article, the front sheet is partially fixed to the second sheet of the above-mentioned 156335.doc 201143727. The above-mentioned front sheet is a sheet having a plurality of divided regions which are scribed by linear embossing, and has a pore diameter of 1 to 600 μm in a pore size measurement using a mercury pore meter. The amount of pores from the Q domain below μηι is less than 1% of the total pore volume. The above second sheet is a sheet in which the constituent fibers are synthetic fibers having a thickness of 〇·15 to 0.4 mm and a liquid holding amount of 60 g/m 2 or less. [Embodiment] Hereinafter, the present invention will be described with reference to the drawings and based on preferred embodiments. The absorbent article according to an embodiment of the present invention is a menstrual sanitary napkin 1, as shown in Figs. 1 and 4, and is disposed on the skin. The front sheet 2 on the contact surface side, the back sheet 3 disposed on the non-skin contact surface side, the absorber 4 disposed between the front sheet 2 and the back sheet 3, and the absorbent body and the front sheet 2 between the second sheet 5. In addition, in the present specification, the "skin contact surface side" is the side of the front side and the back side of the member of the menstrual period sanitary napkin 1 which is placed on the side of the wearer's skin side when worn. The "non-skin contact surface side" is placed on the opposite side of the wearer's skin side when worn. The so-called "γ-direction" shown in the figure, in the direction of the longitudinal direction of the menstrual period, the "X-direction" is perpendicular to the direction of the x-ray and is in the direction of the width direction of the menstrual napkin 1. As shown in Fig. 1 and Fig. 4, in the present embodiment, the rectangular absorber 4 and the dam absorber 4 which are long in the same direction as the direction J after wearing are substantially the same shape and the same. The second sheet of size 5. The second sheet 5 is disposed on the skin contact surface side of the absorbent body 156335.doc 201143727 4. As shown in FIG. 1 and FIG. 4, the front sheet 2 is broken over the entire area of the skin contact surface side of the rectangular second sheet 5, and includes the longitudinal direction of the self-absorbent body 4 and the second sheet 5, respectively. Both ends of the Y direction) and the sides extending to the outside. As shown in FIG. 4 and FIG. 4, the back sheet 3 is applied over the entire non-skin contact surface side of the absorber 4, and includes two longitudinal directions (Y directions) of the self-absorbent body 4 and the second sheet 5, respectively. The end and the sides extend out to the outside. As shown in FIG. 1, the front sheet 2 and the back sheet 3 are melted (hot pressed) at portions extending from the both ends of the longitudinal direction (Y direction) of the absorber 4 and the second sheet 5 to the outside. As shown in FIG. 4, the pattern extends to the outer side of the longitudinal direction (Y direction) of the absorber 4 and the second sheet 5, respectively. It is fixed by an adhesive. Thus, the absorbent body 4 and the second sheet 5 are sandwiched by the front sheet 2 and the back sheet 3. As shown in Fig. 4, the front sheet 2 of the menstrual sanitary napkin has a plurality of compartmental regions 22 which are zoned by linear embossments 21. Since the front sheet 2 has the zoning region 22, it is difficult for the body fluid of the wearer absorbed into one of the zoning regions 22 to spread over the zoning region 2 2 and diffuse to the adjacent other zoning region 22. Here, the "linear embossing" is as follows. The embossed shape is not limited to a straight line but also includes a curved line in plan view, and the embossed shape is a continuous line, and does not include a broken line such as a broken line. However, even if the line of discontinuity is less than 丨mm, the real f has the same effect as the continuous line, and therefore belongs to the embossed liters. The shape of the zoned zone 22 may be quadrilateral or curved by a curve in addition to the diamond lattice pattern. Especially good for the scorpion pattern. 156335.doc 201143727 In the front sheet 2 of the present embodiment, as shown in FIG. 3, the linear embossing 21' includes a plurality of ith-line embossments 21a which are formed parallel to each other and formed at specific intervals. And a plurality of second linear embossments 21b formed parallel to each other at a predetermined interval, and the first linear embossing 21a and the second linear embossing 21b intersect each other at an angle α. The groove width of the second ridge embossing 2 ia is the same as the groove width of the second linear embossing 2 lb, and the interval between the adjacent first linear embossments 21a is W2 and the adjacent second line. The embossing 2 lb is also spaced apart from each other. As shown in Fig. 3, the groove width wi of the first linear embossing 2 la is preferably 〇·1 to 1.5 mm from the viewpoint of surely fixing the constituent fibers in the linear embossing. More preferably, it is 0.3 to 9.9 mm. Further, the interval W2 of the first linear embossing 21a is preferably 2 to 14 mm from the viewpoint of liquid permeation and liquid absorption. It is 2~8 mm. The groove width W1 and the interval W2 are measured in a direction orthogonal to the line. The width of the line can also vary from the intersection point, but the W1 is measured at the intersection of the intersection and the intersection. The W2 is measured by connecting the opposite sides of the zonal region 22 to each other. The front sheet 2 of the present embodiment is formed into a linear embossing 21 by forming a linear embossing 21 from the skin contact surface side toward the skin side of the wearer when assembled into the menstrual sanitary napkin, and is formed in a line shape. The portion of the embossing 21 becomes a recess. At the portion of the linear embossing 21, fibers having the following constitution are thermally fused in the thickness direction. Since the linear embossing 21 is formed in a lattice shape by the second-line embossing 21a and the second linear embossing 21b, the front sheet 2 is formed with a linear embossing. 21 and regionalized areas 22, 22... Each division 156335.doc 201143727 The area 22 is an area surrounded by linear embossments 21 and has a rhombic shape in plan view. The central portion of each of the divisional regions 22 is raised relative to the linear embossing 21 (concave portion) surrounding the divisional region 22 to become a convex portion. As the front sheet 2 of the present invention, a sheet having high permeability is used. It is known that a good liquid permeability is exhibited in a void formed by the distribution of fibers in a sheet, particularly in the case where the microporous region is small, and specifically, a sheet which is obtained by using a mercury pore meter In the micropore distribution measurement of the micro-aperture, the micropore of the region having a pore diameter of 100 μη or less is less than 1% by weight of the total pore volume, and preferably the pore volume is 8 of the total pore volume. The sheet below %, more preferably 6% or less. Therefore, the lower limit of the pore volume of the region having a pore diameter of 100 μη or less is not particularly limited. The pore size distribution of the front sheet 2 was measured by a mercury permeation method (JIS (Japanese Industrial Standards) R 1655) using a mercury pore liquid (Shimadzu Corporation). The mercury infiltration method is a method for obtaining information on the physical shape of the front sheet 2 by measuring the size of the constituent fibers (micropores) of the front sheet 2 or the volume thereof. The principle of the mercury infiltration method is to apply pressure to mercury and press it into the pores of the object to be measured, and to measure the relationship between the pressure applied at this time and the volume of mercury injected (infiltrated). Hereinafter, a method of measuring the pore size distribution of the front sheet 2 using a mercury pore meter will be described. [Method for Measuring Micropore Aperture Distribution of Front Sheet] First, the front sheet 2 was taken out from the menstrual napkin 1 (absorbent article). Eight people cut the removed front sheet 2 into 24 mm x 1 5 mm. Co-cut I56335.doc 201143727 Cut 3 pieces' and place the cut samples in a sample box of a mercury pore meter (Shimadzu Corporation) without measuring each other, and measure the micropore diameter of 600 μπΐ2. . Based on the obtained micropore distribution curve (differential and integral curve) of the front sheet 2, the total of the micropore volume throughout the micropore diameter of 600 μm is taken as the total micropore volume, and the micropore diameter of 100 μm or less is determined. The ratio of the amount of microporous grains in the region to the total k pore capacity described above. Further, based on the pore distribution curve (differential. integral curve) of the obtained front sheet 2, the ratio of the pore volume of the region of the micropore diameter of 1 to 100 μm to the total pore volume was determined. As described above, in the measurement of the micropore diameter of the micropore using a mercury pore size meter, the micropore volume of the region under the micropore diameter 1〇〇μηια is 1 of the total micropore volume described above. The topsheet 2 of 5% or less includes a hot air non-woven fabric composed of only 4.4 dtex or more of non-thermally stretched fibers, a hot air non-woven fabric composed of heat-expanding fibers of 3.3 dtex or more, and non-thermally stretched fibers of 3.3 dtex or more and The hot air non-woven fabric composed of the heat-extended fiber is preferably a hot air non-woven fabric composed of a non-heat-stretched fiber of 3.3 dtex or more and a heat-extended fiber from the viewpoint of both absorbability and texture. Since the non-woven fabric is further divided by the linear embossing, even if the liquid is intended to be diffused in the non-woven fabric as the front sheet, the diffusion is suppressed by the four positions of the linear C-text, and thus the easy-to-use direction is obtained. Lower liquid permeability. In the case where the front sheet 2 is a hot air non-woven fabric containing heat-extending fibers, the front sheet 2 is shown in the region 22, and the heat (the length of the fiber, the length is elongated by heating, and In the zoning region 22, the 156335.doc 201143727 forks the heat-extended fibers at the intersections of each other by heat fusion to join the non-cloth. Thus, the heat-extended fibers are thermally fused by heat fusion. The f is melted by, for example, a hot air method. The f-fused fiber as the heat-extended fiber preferably has a heat-melting component and a heat extension of a high-melting point component having a bright point higher than the heat-melting component. The conjugated fiber is preferably a composite resin in which a hot-melt component is used as a core and a high-melting component is used as a core core. The hot-melt component and the high-point component are preferably thermoplastic resins. Examples of the condensing component include polyethylene, polypropylene, polybutylene-1, polypenta-1, or such random or block copolymers. Ethylene phthalate, poly(p-dibenzoic acid) , nylon-6 or nylon-66, such as polyamine, etc. As a preferred combination of a hot melt component and a high melting point component, polyethylene and polyethylene terephthalate, polyethylene and polypropylene, The low-concentration poly-p-formic acid is suitable for polyethylene terephthalate, polyethylene phthalate and polybutylene terephthalate, but is not limited to these. The fiber may be an eccentric type other than the same core type, or may be one in which the core component is exposed to one part of the entire circumference of the fiber. The length of the thermally extensible composite fiber is elongated by heating. Fiber, and is at 90. (: Above 'preferably at 11 〇. 延伸~13 generation of fibers extending at a temperature. By using Φ to extend the heat-extended composite fiber when manufacturing the front side' can be used on the front sheet 2 The above-mentioned thermally extensible conjugate fiber is not a fiber which is mostly extended after the completion of the front sheet 2, and which is extended from this state. Further, 2 The thermally extensible composite fiber is also a heat-extensible composite fiber. 156335.doc -]0 - 201143727 The heat-expandable composite fiber is, for example, a fiber in which the crystal state of the resin changes and is elongated by heating, or a fiber which is crimped and processed to eliminate the elongation of the length after crimping. Preferably, the softening point of the hot-melt component is higher than the softening point j 0. 较 and lower than the melting point, the temperature-T elongation is 5 〜娜,更优选为1G〜3G%. A preferred example of the thermally extensible composite fiber 记载 is described in paragraphs [0024] to [〇〇4〇] of Japanese Patent Laid-Open Publication No. Hei. No. 5-35-836. In the case where the front sheet 2 is a hot air non-woven fabric containing heat-extending fibers (thermally stretchable composite fibers), the ratio of the heat-extensible composite fibers to the front sheet is from the viewpoint of texture, concealability, and high permeability. The constituent fibers of 2 are preferably 40 to 100% by mass, more preferably 70 to 100% by mass, still more preferably 95% by mass. The fiber which is prepared in addition to the heat-expandable conjugate fiber may be a fiber (non-composite fiber) containing a thermoplastic resin. In the case where the front sheet 2 is a hot air non-woven fabric comprising a heat-extending fiber (heat-extensible composite fiber), the basis weight thereof is preferably 20 to 50 g/m2. In the case where the front sheet 2 is a hot air non-woven fabric composed of only 4.4 dtex or more (preferably 44 to i () d) of thermally fused fibers (non-thermally stretched fibers), for example, synthetic fibers can be used. a fiber comprising a polyethylene, a polypropylene, a polyethylene terephthalate, a polyacetate such as polybutylene dicarboxylate, and a polyamide such as nylon-6 or nylon-66, or It is formed by two or more types of Kunming. Further, the basis weight thereof is preferably 2 〇 5 5 g/m 2 . The constituent fibers of the second sheet 5 of the heart-warming sanitary napkin 1 are synthetic fibers. Since the second sheet 5 is composed of synthetic fibers in this way, the diffusibility can be suppressed at a lower level 156335.doc 201143727. Further, 4 ^ , in view of lowering the diffusibility and having mechanical properties, the synthetic fiber constituting the second sheet 5 is preferably a weakly water-based fiber.

Further, the mixing mentioned here includes a case where a resin having a different melting point of |V u β κ or more is used as the core-sheath type composite fiber side-by-side type composite fiber. In the calculation, since the second sheet 5 is a sheet having high permeability and moderate diffusibility, the thickness of the sheet 5 is 〇15 to 〇4 _ ', which suppresses the amount of retention of the body fluid and lowers the height. From the viewpoint of permeability, it is preferably 0.15 0.4 mm 'better than 〇2 to 〇3 _. The thickness was measured under a load of G. 5 kPa from the viewpoint of wearing state. In addition, since the second sheet 5 rabbit material is a sheet having a relatively high permeability and moderate diffusibility, it is a sheet having a liquid holding amount of 6 〇 2 or less. From the viewpoint of permeability, it is preferable that the sheet of the %-below material is more preferably a sheet of 25 g/m2 to 5 g/m2. Thus, the lower limit of the liquid holding amount of the second sheet 5 is preferably as low as possible. The liquid holding amount of the first sheet of the material 5 was measured by the following measurement method. [Method for Measuring Liquid Holding Amount] The first #5 is taken out from the menstrual sanitary absorbent article. Next, the second sheet 5 taken out is cut to a knives angle of 5 emx5 em square. The mass of the initial cut sample was measured, and the etched 1 knife was placed in a beaker containing 500 mL of distilled water and allowed to stand for 1 minute. After t /, the cutting sample is taken out, and the 156335.doc •12· 201143727 cut salt sample is placed for ίο minutes while hanging on the bamboo pole. Thereafter, after centrifugation (8 rpm) for 1 minute, the mass was measured and the liquid retention amount was determined according to the following formula. Liquid holding amount (g/m2) = {mass of cut sample after centrifugal dewatering (g)_ mass of initial cut sample (g)} / area of initial cut sample (m2) Ο

The measurement site is set to one site, and the average value thereof is the average interval in the width direction (X direction) of the segment region 22. Further, the interfiber distance of the constituent fibers in the skin contact surface 4a of the absorbent sheet 40 is determined by observing the skin contact surface 4〇a using a scanning electron microscope (SEM). The measurement site was set to one site, and the average value was defined as the distance between the fibers of the constituent fibers in the skin contact surface 40a. In the menstrual napkin 1 of the present embodiment, as shown in FIG. 2 and FIG. 2, the front surface of the front sheet 2 is provided with the front side lb, lb along the longitudinal direction (γ direction) of the menstrual napkin i. The sheet 2, the second sheet $ and the absorbent body 4 are integrally compressed to form a leakage preventing groove 6. In the present embodiment, as shown in FIG. 1, the both side portions ' of the front sheet 2 ◎ of the excretion portion region A that is in contact with the body fluid discharge portion of the wearer are formed to be convex toward the outer side in the X direction in a plan view. One of the pair of leakage preventing grooves 6A, 6A is formed in a front region B extending before the excretion portion region a and a rear region c extending to the rear of the excretion portion region a, respectively, and is bent outward in the X direction in a plan view. It is a pair of convex leakage preventing grooves 6B and 6B and a pair of leakage preventing grooves 6C and 6C. In the leakage preventing groove 6 of the present embodiment, as shown in Fig. 1, the leakage preventing groove 6A, the leakage preventing groove 6B and the leakage preventing groove 6C are connected to each other to form an annular full circumferential groove. In the menstrual sanitary napkin 1, as described above, the front sheet 2 and the second sheet 5 are partially fixed. In the present embodiment, as shown in Fig. 4, the second sheet 5 156335.doc -17- 201143727 and the absorber 4 are partially fixed by the leakage preventing groove 6. That is, when the leakage preventing groove 6 is removed, the second sheet 5 and the absorber 4 cannot be fixed. As will be described in detail, the front sheet 2 and the second sheet 5 are intermittently coated with an adhesive or intermittently heat-sealed, and partially fixed, particularly in the line forming the divisional region 22 of the front sheet 2. The front sheet 2 and the second sheet 5 are intermittently fixed at the position of the embossing 21 (recess). Further, as described above, the skin contact surface 4a of the absorbent body 4 is subjected to wrinkle treatment, so that the uneven shape is formed in a wrinkled shape. Therefore, the second sheet 5 and the absorber 4 are in a region other than the leakage preventing groove 6, and as shown in Fig. 5, the uneven shape of the skin contacting surface 40a of the absorbent sheet 4 formed by the creping treatment is A space is formed between the second sheets 5. The material for forming the menstrual napkin 1 of the present embodiment will be described below. The front sheet 2 and the back sheet 3 are not particularly limited as long as they are usually used in an absorbent article such as a sanitary napkin or a sanitary pad. For example, as the front sheet 2, a hydrophilic and liquid permeable non-woven fabric or an apertured film, a laminate thereof, or the like can be used, and as the back sheet 3, a liquid impervious or water repellent resin film or resin can be used. A laminate of a film and a non-woven fabric. Examples of the processing method for forming the leakage preventing groove 6 include embossing processing, hot embossing processing, ultrasonic embossing processing, and a combination processing method thereof. Hereinafter, the effects of the above-described menstrual sanitary napkin 1 as an embodiment of the present invention will be described. As shown in Fig. 1 and Fig. 4, the menstrual sanitary napkin of the present embodiment comprises a front sheet 2 and a second sheet 5, and the front sheet 2 has an embossing by a line 156335.doc -18- 201143727 21 And the plurality of division areas 22 are zoned, so the M is drilled, and the micro-aperture distribution measurement order by the mercury pore meter satisfies the specific requirements and has high permeability; the second sheet 5 is It is composed of synthetic fibers, so that its diffusibility is low, and the thickness and liquid holding amount satisfy specific requirements and have high permeability. Since the menstrual sanitary napkin of the present embodiment is formed by partially fixing the front sheet 2 and the second sheet 5 having low diffusibility and high permeability as described above, the menstrual sanitary napkin is used. At 1 o'clock, it is difficult for the body fluid excreted by the wearer to expand on the surface of the front sheet 2, and the liquid residue of the body fluid in the front sheet 2 or the second sheet 5 other than the absorber 4 can be reduced, and the body fluid can be shortened. The time of transfer to the absorber 4. Further, as shown in Fig. 5, the menstrual sanitary napkin 1 of the present embodiment includes the absorbent sheet 40' subjected to the creping treatment, and the second sheet 5 and the absorbent sheet 4 are not disposed outside the leakage preventing groove 6. In addition, a space is formed between the uneven shape of the skin contact surface 40a of the absorbent sheet 40 and the second sheet 5. Therefore, the body fluid passing through the front sheet 2 and the second sheet 5 is easily diffused between the second sheet 5 and the absorbent sheet 4, so that a large amount of excreted body fluid can be instantaneously transferred from the surface of the front sheet 2 ,. Further, the body fluid which is transferred and diffused can be absorbed while effectively utilizing the absorption area of the absorbent sheet 40. In the measurement of the liquid diffusibility in the state of the absorbent article (menstrual sanitary napkin 1), it is preferable that the liquid diffusion area of the absorbent body 4 is the liquid of the front sheet 2 in the menstrual napkin 1 of the present embodiment. The diffusion area is 1.6 times or more, more preferably 2 times or more. The liquid diffusion area which is an index of liquid diffusibility is measured by the following measurement method. Further, the upper limit value is not particularly limited, and the higher the better, but if it is about 1.8 times, the effect that the 156335.doc •19-201143727 is sufficient can be obtained.

A cotton web is prepared, and the cotton web is introduced into a hot air spraying device, and hot air processing is performed by hot air processing to obtain a front sheet. No linear embossing is formed on the obtained front sheet. 'There are a plurality of three-dimensional openings formed. The opening area ratio of the three-dimensional opening is 6%' and the forming interval of the three-dimensional opening is 2 mm. According to the above [measurement method of microporosity distribution of the front sheet] Micro-pore distribution of the front sheet Then, the micropore volume of the region below the micropore diameter of 1 为 is 35 % of the total pore volume. Further, the basis weight of the obtained front sheet is 25 g/m 2 . [Comparative Example 2] The front sheet of the basis weight of 25 g/m2 used in Example 1 was changed 156335.doc -23- 201143727 was a front sheet having a basis weight of 30 g/m, and the first sheet used in Example i was not used. In addition to the above, a menstrual sanitary napkin of Comparative Example 2 was obtained in the same manner as in the above Example. The microporosity of the produced front sheet was measured according to the above [Method for Measuring Microporosity Distribution of the Front Sheet] In the distribution, the micropore volume in the region of the micropore diameter of 100 μηι or less is 80/〇〇 of the total pore volume [Evaluation] The following evaluation was carried out using each menstrual sanitary napkin, and the results are shown in Table 2. The diffusion area of the front sheet and the absorbent body was measured according to the above [Method for Measuring Liquid Diffusibility]. [Liquid residual amount of the front sheet] The measurement was carried out under the conditions of temperature and humidity in an environment of 2 (TC, 65% RH, using an absorbent article (menstrual sanitary napkin 1) that has been placed for more than one day. The sanitary napkin 1 was placed horizontally, and a plate injector made of acrylic (having a hole having a diameter of 10 mm) was placed thereon, a load of 5 g/cm 2 was applied, and defibrated horse blood was dropped (manufactured by Japan Bi〇test Co., Ltd.) 3 After g, and after 3 minutes, the defibrinated horse blood was dropped from the same position (after the production of p from Japan Bi〇test), the front sheet was taken out from the menstrual sanitary napkin, and the weight of the front sheet before and after the injection was measured. 'And measure the weight of the defibrinated horse blood remaining in the sheet and use it as the liquid residual amount of the front sheet. [Absorption time of body fluid] The measurement is in 2 (TC, 65% rh environment, the use has been placed 丨Absorbent articles above the day (menstrual sanitary napkins 1}, under the conditions of temperature and humidity. 156335.doc 24- 201143727 Place the sanitary napkin 1 horizontally and place the acrylic plate injector (with diameter 10) Hole of mm), apply 5 g/ After the load of cm2 was dropped, 3 g of horse blood (manufactured by Biotest Co., Ltd.) was dropped, and 3 hours later, 3 g of horse blood (manufactured by Sakamoto Biotest Co., Ltd.) was dropped from the same position, and the horse was measured by visual inspection. The time from the time when the front sheet was completely transferred to the absorbent body, and it was taken as the absorption time of the body fluid of the menstrual sanitary napkin.

The liquid residual amount was small. Further, it was found that the absorption time of the body fluid in the samples of Example 1 and Example 2 was shorter than that of the samples of Comparative Example 1 and Comparative Example 2. Utilization according to the invention The product can make the body fluid difficult to spread on the surface, and can reduce the liquid residue of the body fluid outside the absorber, and can shorten the time for the body fluid to transfer to the absorber.
