Embodiment 1

[0177] Make the basic structure with figure 1 The sanitary napkin 1 shown is identical to a menstrual sanitary napkin.

[0178] Use gram weight 30g / m 2 The hot air non-woven fabric is used as the front sheet, and the weight is 37g / m 2 A polyethylene resin film (FL-KDJ100nN, manufactured by Daehwa Industry Co., Ltd.) was used as the back sheet. The absorbent body uses fiber blocks and absorbent fibers as the fiber material of the absorbent core, and further uses a separately prepared grammage of 16g / m 2 The chip-wrapped tissue paper is manufactured according to the usual method using a known fiber stacking device. The basis for the manufacture of fiber blocks Image 6 , The raw fiber sheet is cut into small cubes and manufactured. The configuration of the fibrous material (fibrous mass, water-absorbent fiber) in the absorbent body of Example 1 is, and image 3 The absorbent body 4 shown is similarly disposed in such a way that the fiber block occupancy rate and the fiber ...

Embodiment 2

[0187] The configuration of the fiber material (fiber block, water-absorbent fiber) in the absorbent body is the same as Figure 4The absorbent body 4A shown also has two positions in the thickness direction with different fiber block occupancy ratios and fiber block ratios. A menstrual napkin was produced in the same manner as in Example 1, as an example. 2. That is, in the absorbent body of the menstrual napkin of Example 2, the skin-facing side is the multi-absorbent fiber portion 12P, and the non-skin-facing side is the multi-fibrous block portion 11P. The interface is bonded to each other by entanglement of constituent fibers, and the interface is located at the center in the thickness direction of the absorbent body.

Embodiment 3

[0189] In Example 2, the fiber block occupancy of the multi-absorbent fiber portion 12P was set to 0% by mass, that is, the water-absorbent fiber content on the skin-facing side of the absorber was set to 100% by mass, and the multi-fibrous block The fiber block occupancy of the part 11P was set to 100% by mass, that is, the occupancy of the water-absorbent fibers on the non-skin-facing side of the absorber was set to 0% by mass, and the same absorber was produced as in Example 3. Menstrual sanitary napkins.

Abstract

The absorbent body (4) of the present invention includes a fiber block (11) containing synthetic fibers (11F) and water-absorbent fibers (12F), a plurality of fiber blocks (11) are intertwined with each other or a fiber block (11) and water-absorbent fibers ( 12F) Intertwined. With regard to the content mass ratio (fiber mass ratio) of the fiber mass (11) to the water-absorbent fiber (12F), the skin-facing side (front sheet (2) side) of the absorber (4) is smaller than the non-skin-facing side (back side). piece (3) side). The fiber block (11) has a main body (110) defined by two opposing basic planes (111) and a skeleton plane (112) intersecting the two basic planes (111).

Description

technical field [0001] The present invention relates to an absorber that is used in direct or indirect contact with the skin and is suitable for use as an absorber for absorbent articles. Background technique [0002] Generally, absorbent articles such as disposable diapers and sanitary napkins include a front sheet disposed relatively close to the wearer's skin, a back sheet disposed relatively far away from the wearer's skin, and a back sheet between the two sheets. between absorbers. Typically, the absorber mainly contains water-absorbing fibers such as wood pulp in many cases, and also contains water-absorbing polymer particles. With regard to absorbent cores used in absorbent articles, improvement of various properties such as softness (cushioning properties), compression recovery properties, and shape retention properties has become an important issue. [0003] As an improvement technique of an absorbent body, for example, Patent Document 1 describes an absorbent bod...
