Problems solved by technology
[0006] Therefore, it is generally considered that when the skin comes into contact with the nonwoven fabric, especially when the nonwoven fabric is pressed in the thickness direction or the skin is slipped in the plane direction of the nonwoven fabric, there is a relatively hard part around the periphery of the through hole. The possibility of feeling obvious discomfort when touching the skin, which greatly damages the skin feel of non-woven fabrics

Embodiment Construction
[0033] Figure 1 to Figure 4 One embodiment of the nonwoven fabric for absorbent articles of the present invention is shown, and the nonwoven fabric 1 of this embodiment has Figure 1 to Figure 4 Among them, the upper surface 2 as the first surface and the lower surface 3 as the second surface opposite to the upper surface 2 include the convex portion 4 protruding to the upper surface 2 side and the groove recessed to the lower surface 3 side. Part 5 is a material for absorbent articles containing thermoplastic resin fibers.
[0034] In addition, the nonwoven fabric of the present invention is suitably used as a top sheet and a leak-proof wall of absorbent articles such as disposable diapers, sanitary napkins for menstruation, urine-proof pads, and panty liners for menstruation, that is, it is arranged on the side of absorbent articles. The side of the sheet that is in contact with the user's skin. Alternatively, it can also be used as a sheet to be stuck on the outer side s...

The objective of the present invention is to obtain a non-woven fabric for an absorbent article, said fabric making it possible to always ensure a soft feel in contact with the skin. The invention is configured to be provided, in a groove bottom portion (6) of a groove portion (5) provided in the space between adjacent protrusions (4), (4), with a plurality of recesses (7) having a bottom portion (9) that is deeper than the groove bottom portion (6) and being provided non-contiguously relative to a first direction (X), wherein at least a portion of the peripheral surfaces of the recesses (7) is provided with a hole portion (11) that communicates with a second surface side, the hole portion (11) has a peripheral edge portion (12) that is formed without melting a thermoplastic resin fiber, and the peripheral edge portion includes a broken end (13a) of a broken fiber (13) of a thermoplastic resin fiber, said broken fiber (13) being formed by breaking.
Description
technical field [0001] The present invention relates to a nonwoven fabric used in absorbent articles such as disposable diapers, sanitary napkins for menstrual periods, and incontinence pads. Background technique [0002] For example, in absorbent articles such as disposable diapers, since the nonwoven fabric used as a constituent member such as a top sheet is a part that contacts the user's skin, softness and good skin touch are important conditions. [0003] Therefore, in recent years, the following nonwoven fabrics are often used. The surface of the nonwoven fabric in contact with the skin is provided with a plurality of rows of ridge-shaped convex parts and grooves provided in the spaces between adjacent convex parts. In the woven fabric, since the relatively soft convex parts come into contact with the skin, and the convex parts tend to fit the skin surface easily, the softness of the nonwoven fabric tends to be felt easily. [0004] In order to further improve the sof...
