Definitions
- the present invention relates to a surface sheet or a laminated nonwoven fabric suitably used for a skin contact surface of an absorbent article such as a disposable diaper, a sanitary napkin, a panty liner (corimono sheet), and an incontinence pad.
- an absorbent article such as a disposable diaper, a sanitary napkin, a panty liner (corimono sheet), and an incontinence pad.
- a surface sheet such as disposable diapers and sanitary napkins, those having irregularities formed on the surface in contact with the skin of the wearer are widely used. According to the uneven surface sheet, since the contact area with the wearer's skin is reduced due to the presence of the unevenness, the stickiness can be reduced.
- a surface sheet is known in which a thick sheet material is integrated with another sheet material by embossing, and the embossed compression part is a concave part and the other part is a convex part.
- this surface sheet is limited depending on the properties of the sheet material that can be designed.
- FIG. 3 is an enlarged view of a main part of the first roll in FIG. 2.
- the thickness of each of the first nonwoven fabric, the short fiber layer, and the second nonwoven fabric is measured at the thickest portion of the cut surface of the topsheet 10. Measurement is performed by cross-sectional observation using a microscope VH-8000 (manufactured by Keyence) at a magnification of 50 times. The cross section is obtained by cutting with a feather razor (part number FAS-10, manufactured by Feather Safety Razor Co., Ltd.). On this cut surface, an image showing the thickness of the heat-sealed part and the convex part before absorbing the liquid is recorded, measured and calculated.
- the fiber density p 1 of the first nonwoven fabric 1, the fiber density of the short fibers (the fiber density of the short fibers as the fiber assembly 3) p 2 and the fiber density p 3 of the second nonwoven fabric 2 have the following relationship: I like it.
- the surface sheet has a good liquid flow-in preventing property due to the discontinuous convex portions 5 in addition to a good liquid drawing property due to the fiber density gradient of the convex portions.
- the urine, menstrual blood and the like excreted on the top 10 permeate the surface sheet 10 through a relatively narrow range and are absorbed by the absorber below the surface sheet 10.
- the bottom dimension A (see Fig. 1) of the convex part 5 in the X direction is 0.5 to 5. Omm, especially 1.0 to 4. Omm. It is preferable that The bottom dimension B (see Fig. 1) in the Y direction of the protrusion 5 is preferably 1.0 to LOmm, particularly 2.0 to 7. Omm.
- Non-thermo-adhesive fibers have a thickness of 0.5 to 6.6 dtex, especially 1.1 to 3.3 dtex.
- the preferred basis weight is 5 to 50 g / m 2 , especially 10 to 30 g / m. 2 is preferred.
- the hydrophilicity of the constituent fibers increases in this order. It is preferable from the viewpoint of improvement.
- the degree of hydrophilicity of these three parties can be determined by determining the angle between the surface of the water droplet and the angle of the water droplet placed on one fiber (by spraying, etc.) using the contact angle measurement method.
- the short fibers 31 are supplied in a scattered state by the known fiber supply means 14 to the peripheral surface of the first roll 11 in a state where the first nonwoven fabric 1 is in close contact therewith.
- the short fiber 31 is conveyed to the peripheral surface of the first roll 11 along the air flow generated in the duct 14a covering a part of the first roll 11, and is sucked from the suction hole 13 by suction. It selectively accumulates in the recesses of the roll 11.
- the air flow in the duct 14a can be generated by suction from the suction holes 13 and Z or other blowing means (not shown).
- the surface sheet 10 is obtained.
- the topsheet 10 is used for absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads.
- Absorbent materials generally have a liquid-permeable top sheet, a liquid-impermeable back sheet, and a liquid-retaining absorbent disposed between both sheets.
