Embodiment 1

[0142] Using polypropylene (PP) resin as a raw material, an average fiber diameter of 10 μm and a mass per unit area of ​​30 g / m were obtained by melt-blowing 2 of non-woven fabrics. After being calendered at a temperature of 40°C and a linear pressure of 250kgf / cm, it was immersed in an aqueous solution of 0.05% surfactant (Maidol 10 produced by Kao Corporation) and dried naturally to obtain a sample without spinning.

[0143] When the pore size distribution of the obtained sample nonwoven fabric was measured by the above-mentioned pore size distribution measuring method, the proportion of pores with a pore size of 6 μm or less was 20%. The obtained sample non-woven fabric was cut into a size of 15 cm in length and 6 cm in width, which was used as a blood separator, and sandwiched between the front surface taken out from a commercially available sanitary napkin (manufactured by Kao Co., Ltd. Between the sheet and the back sheet, a sanitary napkin is produced.

Embodiment 2

[0145] Using the same sample non-woven fabric as in Example 1 as a blood separator, the mass per unit area manufactured by the hot air method is 40g / m 2 The non-woven fabric is used as the middle sheet, sandwiching them between the front sheet and the back sheet. The blood separator and the intermediate sheet are arranged such that the intermediate sheet is on the side of the front sheet and the blood separator is on the side of the back sheet. Except for this, a sanitary napkin was produced in the same manner as in Example 1.

Embodiment 3

[0147] Manufactured using 16-segmented fibers composed of polypropylene (PP) resin and polyethylene (PE) resin, the mass per unit area is 60g / m 2 The fiber web is interwoven by the water flow interweaving method to obtain a non-woven fabric. It was calendered at a temperature of 40°C and a linear pressure of 250 kgf / cm, then immersed in an aqueous solution of 0.05% surfactant (Maidol 10 produced by Kao Corporation) and dried naturally to obtain a sample nonwoven fabric. cloth.

[0148] When the pore size distribution of the obtained sample nonwoven fabric was measured by the above-mentioned pore size distribution measuring method, the proportion of pores with a pore size of 6 μm or less was 40%. A sanitary napkin was produced in the same manner as in Example 1 except that the obtained sample nonwoven fabric was used as a blood separator.

Abstract

An absorptive article (1) of the invention has a blood-separating member (4) which is capable of separating the blood into blood cells and the plasma. As the blood-separating member (4), use can be made of, for example, a material having a ratio of micropores having a diameter of 6 um or less, that is determined in accordance with ASTM F316-86, of from 20 to 90%. As the blood-separating member, use can be made of, for example, a non-woven fabric obtained by calendaring a fiber mass.

Description

technical field [0001] The present invention relates to an absorbent article with little return of menstrual blood (blood). Background technique [0002] In absorbent articles such as sanitary napkins intended to absorb menstrual blood or blood, menstrual blood or the like absorbed into the absorber from the skin-contacting surface returns to the skin-contacting surface due to pressure or the like, causing stickiness. [0003] As a method of reducing stickiness, the surface sheet forming the skin contact surface is provided with unevenness to reduce the contact area with the skin, or a bulky non-woven fabric is used in the surface sheet, but the performance required for absorbent articles is increasing year by year. Improvement, only the efforts of the front sheet, may not be able to fully meet the requirements in recent years or in the near future. [0004] In addition, in Japanese Patent Laid-Open No. 2001-348728 (hereinafter referred to as Document 1), useful polyester-b...
