DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. The sanitary napkin 1 as the first embodiment of the present invention includes a vertically long absorbent main body 11 having a liquid-retaining absorbent layer 12 and a liquid-impermeable back layer 16 as shown in FIGS. And a pair of wing portions 21 provided on both sides of the absorbent main body 11 in the longitudinal direction.
[0009]
The absorbent layer 12 is composed of a liquid-permeable top sheet 13 and a liquid-retaining absorbent body 14, and the back layer 16 is composed of a liquid-impermeable back sheet 16. Since the back surface layer 16 in this embodiment consists only of a back surface sheet, the same code | symbol 16 is attached | subjected to both.
The absorber 14 is sandwiched and fixed between the top sheet 13 and the back sheet 16. Three-dimensional guard forming sheets 15 ′ are arranged along the longitudinal direction on both sides in the longitudinal direction of the absorbent main body 11 to form the three-dimensional guard 15. On the non-skin contact surface of the absorbent main body 11, a main body adhesive portion 17 used for joining with shorts is provided.
[0010]
As shown in FIG. 2, the pair of wing portions 21 is formed by fixing wing portion forming sheets 22 to the left and right side edge portions in the longitudinal center portion of the absorbent main body 11. The wing portion forming sheet 22 is sandwiched between the three-dimensional guard forming sheet 15 ′ and the back sheet 16, and is subjected to a sealing process by heat or ultrasonic wave integrally with these sheets, and one end thereof. The vicinity of the part is fixed. By this sealing process, seal portions 18 having a circular arc shape in a plan view are formed on the left and right side portions of the central portion in the longitudinal direction of the absorbent main body 11. The absorbent body 14 has a vertically long shape in the same direction as the longitudinal direction of the absorbent main body 11, and has both side edges 14 a curved along the seal portion immediately inside the seal portion 18. .
[0011]
The wing portion 21 extends outward in the width direction of the napkin 1 from both side edges 14a in the longitudinal direction of the absorbent body 14, and at least a tip portion thereof is in a state where the napkin 1 is fixed to a crotch portion 5 of underwear such as shorts. It is a portion arranged on the outer surface side of the underwear such as shorts. The base end portion 21 a of the wing portion 21 is a portion where the longitudinal side edges 14 a of the absorbent body 14 are located.
[0012]
Each wing portion 21 has a laminated structure including a stretchable nonwoven fabric 23 and a nonstretchable sheet 27 laminated on the non-skin contact surface side of the nonwoven fabric at a portion near the base end portion 21a. Yes.
In the present embodiment, as the wing portion forming sheet 22, a laminated sheet in which an extensible nonwoven fabric 23 and a non-extensible sheet 27 are bonded to each other in a laminated state is used, and the entire area of the wing portion 21 is It has a laminated structure consisting of an extensible nonwoven fabric 23 and a non-extensible sheet 27.
[0013]
Examples of the stretchable non-woven fabric 23 include a non-woven fabric that is adjusted with less heat fusion points and entanglement, and a non-woven fabric that has been subjected to concavo-convex processing, such as improved fit to underwear or followability when worn. Therefore, the elastic nonwoven fabric is particularly preferable.
Stretchable non-woven fabric does not decrease the fit of the wing part to the crotch (crotch part) side edge of the shorts etc. It is preferable from the fact that the fit property is stably maintained repeatedly.
[0014]
Examples of the stretchable nonwoven fabric include a nonwoven fabric that contains three-dimensionally crimped fibers and exhibits stretchability due to the entanglement of the fibers, and a nonwoven fabric that exhibits stretchability by an elastomer material such as natural rubber, synthetic rubber, and spandex. It can be preferably used. The stretchable (stretchable) nonwoven fabric may be a single layer or two or more layers, or a composite nonwoven fabric of a nonwoven fabric and other materials. In the case of a composite nonwoven fabric, the nonwoven fabric side is arranged on the skin contact surface side.
[0015]
The stretchable nonwoven fabric according to the present invention has stretchability in at least one direction, and the stretchability of the stretchable nonwoven fabric is the original natural length when the nonwoven fabric in a single state is stretched with a load of 0.5 N / cm. The stretchability is preferably 1.2 to 3 times, particularly 1.5 to 2.5 times the length of the state (state where no external force is applied). A load of 0.5 N / cm corresponds to a tensile load when the wing is mounted.
[0016]
In this embodiment, as shown in FIG. 2, the stretchable nonwoven fabric 23 includes a first fiber layer 24 including crimped fibers that are three-dimensionally crimped and crimped fibers that are three-dimensionally crimped. A second fiber layer 25 containing no or three-dimensionally crimped fibers at a lower content than in the first fiber layer 24, and the first fiber layer 24 and the second fiber layer 25 are partially A stretchable laminated nonwoven fabric that is heat-sealed and integrated with each other is used. The laminated nonwoven fabric includes a first fiber layer forming material including a latent crimpable fiber that develops crimps by heat shrinkage of the constituent components, and a fiber that does not thermally shrink below the shrinkage start temperature of the latent crimpable fiber. After the two fiber layer forming materials are laminated with each other, both are partially heat-sealed by heat or ultrasonic embossing to produce an intermediate body in which a large number of heat-sealed portions 26 are formed in a dispersed state The intermediate body is obtained by heat-treating and heat-shrinking the first fiber layer forming material, and the second fiber layer 25 side has a large number of independent protrusions or continuous protrusions. An uneven shape is formed.
[0017]
In the present embodiment, the first fiber layer 24 side forms a non-skin contact surface of both wing portions 21, and the second fiber layer 25 side forms a skin contact surface of both wing portions 21. The non-skin contact surface and the skin contact surface of the wing portion are the back surfaces of the absorbent main body 11 in a state where both the wing portions 21 are expanded on both the left and right sides of the absorbent main body 11 as shown in FIGS. A surface directed in the same direction as the surface on the sheet 16 side and a surface directed toward the opposite side. The wing portion 21 in the present embodiment has a skin contact surface on the side of the second fiber layer 25 having an uneven shape, and is further excellent in cushioning properties and texture (softness of touching the skin).
[0018]
The latent crimpable fiber is a fiber that can be handled in the same manner as a conventional nonwoven fabric fiber before being heated, and has a property that a helical crimp is developed and contracted by heating at a predetermined temperature. is there. When the latent crimpable fiber is used, both the heat shrinkage of the first fiber layer during the production of the nonwoven fabric and the stretchability after shrinkage can be realized.
The latent crimpable fiber includes, for example, an eccentric core-sheath type composite fiber or a side-by-side type composite fiber containing two types of thermoplastic polymer materials having different shrinkage rates as components. Examples of the thermoplastic polymer material include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, and polyamides. As the laminated nonwoven fabric having such a configuration, for example, a three-dimensional sheet material described in JP-A-2002-187228 can be preferably used.
[0019]
As another stretchable nonwoven fabric, a stretchable composite nonwoven fabric obtained by laminating and integrating stretchable fiber aggregates (nonwoven fabric or fiber web) on one or both sides of a sheet made of an elastomer material can also be used. . As the elastomer material, natural rubber, synthetic rubber such as butadiene and isoprene, and the like are preferably used. As the sheet made of the elastomer material, an elastic film obtained by forming the elastomer material into a film, a sheet obtained by forming an elastic fiber made of the elastomer material into a net shape or a non-woven fabric, and the like are preferably used. As the fiber assembly, thermoplastic polyurethane fiber, highly crimped polyethylene fiber, highly crimped polyester fiber, or the like can be used. Examples of the method for fixing the fiber assembly to the sheet made of the elastomer material include a method for fixing the fiber assembly to the sheet by heat fusion.
[0020]
The non-stretchable sheet in the present invention is less stretchable than a stretchable nonwoven fabric. For example, when the sheet is stretched with a load of 0.5 N / cm without forming slits or long holes described later. The length is 1.1 times or less, especially 1.05 times or less of the length of the original natural state (a state in which no external force is applied) in any direction.
Examples of the non-extensible sheet include thermoplastic resin films such as polyethylene, polypropylene, polyvinyl acetate, and polyester, water-repellent spunbond nonwoven fabric, and spunbond-meltblown-spunbond nonwoven fabric. From the viewpoint of the application of the wing adhesive, those having a smooth surface are preferred. In addition, from the viewpoint of the bondability of a fixing material such as a male material, a material having surface strength that can withstand repeated adhesion is desirable.
[0021]
Examples of the bonding method between the nonwoven fabric and the non-extensible sheet include adhesion with an adhesive, heat sealing using heat sealing, ultrasonic sealing, and the like, and ultrasonic sealing is preferable from the viewpoint of softness and flexibility.
[0022]
In addition, the nonwoven fabric and the non-stretchable sheet may be bonded to each other over the entire surface, but are preferably partially bonded from the viewpoint of touch and ease of bending of the wing part. In particular, it is preferable that the bonded portions and the non-bonded portions are partially bonded in a pattern. Examples of the method of partial bonding include a method of applying an adhesive with a pattern, and a method of pattern embossing by heat or ultrasonic waves. Examples of the adhesive or emboss pattern include a dot pattern, a stripe pattern (striped pattern), a lattice pattern, and a checkered pattern.
[0023]
The non-stretchable sheet 27 having a laminated structure of the stretchable (stretchable) non-woven fabric 23 and the non-stretchable sheet 27 penetrates the non-stretchable sheet 27 in a portion near the base end portion 21a of the wing portion 21. A plurality of slits 28 are formed. This slit is formed by making a linear cut in the non-stretchable sheet 27 before being laminated with the nonwoven fabric 23, and this slit (same in the case of a long hole) penetrates only the non-stretchable sheet. The nonwoven fabric 23 is not penetrated. That is, the slit 27 is formed only in the non-extensible sheet in the thickness direction of the wing portion 21 and does not extend over the nonwoven fabric 23.
