Abstract

In this absorbent article, in order to enable a wearer or the like to easily dispose an auxiliary absorbent article at an appropriate position, a tape-type disposable diaper (100) is formed by connecting a back region (110), a crotch region (120), and a front region (130). A top sheet (10), an absorbent body (30), a polyethylene sheet (40), and a back sheet (20) are disposed therein. The polyethylene sheet (40) is formed with lines (S1, S2) that are linear marks extending continuously from the back region (110) to the front region (130) along a longitudinal direction (L), so that both side edges (201, 301, 401) of inner pads (200, 300, 400) are respectively aligned therewith in a state in which the inner pads (200, 300, 400) are disposed at appropriate positions in a width direction (W). The absorbent body (30) is formed with a width that does not cover the lines (S1, S2). The top sheet (10) allows optical transmission of the lines (S1, S2).

[Solution] The problem is solved as follows: an absorbent body 56 spanning from a front portion F to a back portion B is formed by two layers of absorbent layers 55, an absorbent layer 55a with a slit 40 is provided with a slit 40 that is continuous in a longitudinal direction LD without branching, and the two lateral edges 59 of the slit 40 are spaced apart in a width direction WD in an unfolded state and have a first portion 40a where a spacing d1 between the two lateral edges 59 of the slit 40 in the width direction WD is the minimum spacing and a second portion 40b where a spacing d2 in the width direction WD is the maximum spacing wider than in the first portion 40a. With this arrangement, even if the absorbent body 56 is compressed in the width direction WD and the two lateral edges 59 of the slit 40 come into contact, the gap of the slit 40 is maintained in the portion other than the first portion 40a.

Abstract

[Problem] To provide a toilet roll that satisfies both quality related to the texture, such as softness and fluffiness, and functionality required for use in a cleansing toilet, such as firmness and water absorption, and that is less likely to result in dissatisfaction both during normal use and for use in a toilet with a cleaning function. [Solution] The problem is solved by a toilet roll in which two-ply toilet paper comprising two laminated sheets is wound around a paper tube, the toilet roll having a roll length of 20-40 m and a roll diameter of 110-130 mm, each sheet having a basis weight of 15.5-20.0 g/m2. In the toilet paper, sheets each having depressions on one surface and projections corresponding to the depressions on the other surface are laminated such that the surfaces having the projections formed thereon face each other and are bonded by means of bonding glue at the top portions of the projections, wherein the disintegration freeness is 500 cc to 650 cc inclusive, the ratio of dry tensile strength in the longitudinal and transverse directions is 2.9 to 3.8 inclusive, and the ratio of wet tensile strength to dry tensile strength in the transverse direction is 0.20 to 0.40.

A gather waterproof sheet 64 formed of a waterproof resin film and substantially entirely covering the third portion 66c is fixed to the rising portion 68 to form a high rigidity region. The fourth portion 66d has no gather waterproof sheet 64 and has fewer stacked sheets than the third portion 66c, and bending is less likely to occur between the second gather elastic member 63b and the starting end 61. Thus, the problem described above is solved.

Abstract

[Problem] To improve retention of superabsorbent polymer particles of a hardwood pulp fiber-containing absorber. [Solution] The above problem is solved by an absorbent article, which is provided with an absorbent element 50 having an absorbent body 56 and a wrapping sheet 58 wrapping the absorbent body 56. The absorbent body 56 is formed by mixing and integrating pulp fibers and superabsorbent polymer particles. The proportion of particles having a smaller particle diameter before swelling than the average fiber length of the hardwood pulp fibers in the superabsorbent polymer particles 56p is 60 mass% or more. In the absorbent element 50, a plurality of highly compressed portions 51 are arranged at intervals, wherein the plurality of highly compressed portions 51 are compressed in the thickness direction TD so as to be recessed from the surface of the absorbent element 50 into the absorbent body 56. A portion other than the highly compressed portions 51 in a region where the plurality of highly compressed portions 51 are arranged is a non-highly compressed portion 52 that is thicker and has a lower density than the highly compressed portions 51. Each of the highly compressed portions 51 has a shortest distance to the closest other highly compressed portion 51 of 1 to 4 mm, and an area of each of the highly compressed portions 51 is 2 to 200 mm2.

Abstract

In this pants-type absorbent article, in order to be readily tearable along a vertically-extending side seal and to stabilize a process for forming the side seal, a pants-type disposable diaper (100) is configured to have side seals (50) that are each formed by joining a lateral portion (11) of a ventral section (10) and a lateral portion (31) of a dorsal section (30), and to have a waistline opening (P1) and two leg surrounding openings (P2). The side seals (50) each have formed in the width direction (W) thereof at least two rows of seal portions (51a), (52a) lined up in the vertical direction (H). The seal portion (51a) of an inner-side first row (51) and the seal portion (52a) of an inner-side second row (52) are arranged alternately in the vertical direction (H), and the interval (Dy) along the vertical direction (H) between the seal portion (51a) and the seal portion (52a) is set to 0.8-1.2 [mm]. The seal portions (51a), (52a) are formed such that the vertical dimension (Y) is longer than the transverse dimension (X).

[Solution] A fibrous cellulose composite resin comprising a fibrous cellulose and a resin, characterized in that the fibrous cellulose is a carbamated microfibrous cellulose in which some or all of the hydroxy groups are substituted by carbamate groups and which has a Fine ratio A of 25% or more and a fibrillation ratio of 1.0% or less. A production method of the fibrous cellulose composite resin comprises: processing a starting pulp into a strip-shaped pulp sheet by papermaking; coating the pulp sheet with urea and/or a urea derivative and heating to give a carbamated pulp sheet; defibering the carbamated pulp sheet to give a carbamated microfibrous cellulose having a Fine ratio A of 25% or more and a fibrillation ratio of 1.0% or less; and kneading the carbamated microfibrous cellulose with a resin.

Abstract

In order to provide an absorbent article which is capable of not only reducing skin troubles by reliably preventing frictions between an absorbent article surface and a skin surface but also preventing leakage by improving fit to a gluteal region, an absorber (4) is laminated on a skin side of a back sheet (2), the back sheet (2) and the absorber (4) are left unjoined, a friction-reducing layer (10) is disposed between the back sheet (2) and the absorber (4), and a rear end section of the absorber (4) is divided into multiple parts in a width direction by a dividing part (11) extending in a longitudinal direction of a sanitary napkin (1). When an underwear is moved by movement of a wearer's body, the movement of the underwear is absorbed as the absorber (4) and the back sheet (2) slide with each other such that the movement of the back sheet (2) becomes less likely to be transmitted to the absorber (4). The respective absorber parts divided by the dividing part (11) can flexibly follow different movements of the right and left sides of the gluteal region while sliding relative to the back sheet (2).
