Definitions
- an interlabial pad As such an interlabial pad, the present inventors dispose a liquid-permeable front-side sheet, a liquid-impermeable backside sheet, and a front-side sheet and a backside sheet.
- Interlabial pad with an absorbent material which has a mini-sheet piece attached to one surface of the back sheet (WO 02/0941 4 No. 8 pan fret).
- This interlabial pad is attached to the outside of the interlabial pad between the inner and outer surfaces of the back side sheet, on the side opposite to the side where the absorber is placed. Form a pocket into which you can insert Shall be flat in the surface direction of the sheet.
- the MD / CD ratio of the bending stiffness can be adjusted by randomly arranging the fibers of the fiber assembly.
- the MD / CD ratio of bending stiffness is also affected by the embossing of the absorber and the patterning of slitting, but the fibers are randomly oriented so that the behavior of each fiber can be changed without deviation. This is very important.
- the ratio between the maximum tensile strength in the longitudinal direction and the maximum tensile strength in the transverse direction of the fiber assembly hereinafter referred to as the MD / CD ratio of the maximum tensile strength
- the MD / CD ratio of the maximum tensile strength is preferably in the range of 0.5 to 2.5.
- the interlabial pad according to the present invention when the interlabial pad is folded and attached so that the back side sheets face each other on the center line in the longitudinal direction, in the upper region in contact with the vestibular floor, High weight ratio of high tensile elongation fiber aggregate, high tensile elongation . This makes it easier for the portion in contact with the vestibule floor to stretch, so that the vestibule floor can be further followed.
- FIG. 8B is a diagram showing a state in which the interlabial pad according to the seventh embodiment is worn between the labia.
- the fiber amount in the central region M is larger than the fiber amount in the side region E, and the central portion of the cross section in the thickness direction is Protrudes.
- the fiber assembly 2 42 a having a low tensile elongation and the fiber assembly 2 42 b having a high tensile elongation are laminated, after embossing so that the emboss ratio becomes 1.8%, It is cut into the required shape to make the absorber 222.
- the absorber 22 2 is disposed between the front sheet 21 a and the back sheet 21 b, and at a position 2 to 5 mm outside the outer edge of the absorber 22 2, the front sheet 2 1 Cut a and the back side sheet 2 1 b and join both sheets together to create the interlabial pad 2 Ob. It should be noted that these are merely examples, and the present invention is not limited to these.
- the elongation can be controlled by the pitch in the slit pattern of the slit processing, and the elongation can be increased by reducing the pitch. That is, the slit may be applied to the entire absorber 222.
- the pitch of the upper region and the lowermost region is a slit pattern in which the pitch in the lower region of the absorber is also narrow. It is preferable that
- the slit 26 in the lowermost region C is provided so as to reach the outer edge of the absorber 222, the slit is divided so that the absorber 222 opens in the outer edge direction, and the external impact is further reduced.
- the cushion can be cushioned, and it is difficult to give a foreign body feeling even when searching for the mounting point of the interlabial pad 20d.
- the fibers constituting the absorbent were mainly oriented in the lateral direction. Due to the fiber rigidity, the MDZCD ratio of the bending rigidity of the absorber was very high.
- the interlabial pad consists of a front side sheet, a back side sheet, and a mini sheet piece.
- the so-called flap is cut at a position 3 mm from the periphery of the absorber, and has a maximum of 58 mm and a maximum length of 91 mm. Dimensions. (Example 5)
- Tables 4 to 7 show the structures, densities, bending stiffness and tensile properties in the dry state, and the results of actual use tests for Examples 1, 4, and 5, and Comparative Examples 1, 2, and 3. .
- the method of measuring the bending stiffness and apparent density will be described later.
- 20 women on the first to third days of menstruation were used, the number of panels was set to 5 and the time for wearing on the labia was 2 to 3 hours. " It was confirmed.
- a napkin manufactured by New Charm Co., Ltd. and a brand name “Sofisara hin” registered trademark
- MD / CD * 1 Gurley bending stiffness in MD direction Gurley in ZCD direction Ratio of one bending stiffness
