- Fig. 7 (B) shows an example in which the linear embossing is a cut-off line
- Fig. 7 (C) shows an area near the blood drainage part.
- cam emboss 8 is added and linear emboss 7 is added to other areas.
- the KES compression is used as an index value of the softness to the skin.
- the WC value (compression energy) by the testing machine is 0.8 gf'cm / cm 2 or more, preferably 1. Ogf 'cm / cm 2 or more, more preferably 1.2 gf' cm / cm 2 or more.
- it is desirable that the wet tensile strength is 0.4 N or more, preferably 0.6 N or more as an index value for preventing the paper cotton cracking of the absorbent.
- the tensile strength when wet in the width direction of the absorber is 0.4 N or more, preferably 0.6 N or more, and the tensile strength when wet in the longitudinal direction of the absorber is 1. ON or more, preferably 2. It is more desirable to make it more than ON.
- the KES compression tester (manufactured by Kato Tech Co., Ltd.) is a tester for simulating the feeling of touching an object with a human fingertip, such as compression energy, compression hardness, and compression recovery. Can be measured. As shown in Fig. 8 (A), the sample speed: 0.1 cm / sec, compression area: 2 cm, SENS: 2 (total 200 g / 10v), DEF sensitivity: 5, compression load : 50 gf Compress under the conditions of / cm 2 , and calculate LC (compression hardness), WC (compression energy) and RC (compression recovery) from the correlation diagram between pressure and deformation.
- LC compression hardness
- WC compression energy
- RC compression recovery
- the LC compression hardness
- the LC compression hardness
- the WC compression energy
- the last RC compression recoverability
- WC compression energy
- Specimens with various types of embossing were prepared, and the softness was measured using the WC value (compressed energy) as an index value.
- the results of measuring the test as an index value are shown in the graph of Fig. 9.
- the WC value (compression energy) measured by the KES compression tester is 0.8 gf-cm / cm 2 or more and the wet tensile strength is 0.4 N or more. It can be seen that it satisfies the balance between softness against the skin and the prevention of paper cotton cracking.
- a hydrophilic fiber layer as a so-called second sheet is formed on a lower surface side of the liquid-permeable surface sheet 3 by limiting the region such as a blood drainage portion. It may be arranged as desired, or it may be arranged so as to cover the entire surface of the absorber 4.
- FIG. 1 is a partially broken perspective view of a thin sanitary napkin 1 according to the present invention.
- FIG. 2 is an enlarged cross-sectional view of the main part.
- FIG. 1 [031 (A), (B) are both diagrams showing the arrangement of the nonwoven fabric 6.
- FIG. 1 [031 (A), (B) are both diagrams showing the arrangement of the nonwoven fabric 6.
- FIG. 4 is a cross-sectional view showing another embodiment of the nonwoven fabric 6.
- FIG. 5 is a diagram for giving linear emboss 7.
- FIG. 6 is a vector diagram showing the stretch state of the underwear when worn.
