Embodiment

[0082] As shown in Table 1 below, three kinds of front sheets related to Example 1, Example 2 and Comparative Example 1 were prepared, holes were formed with the specifications shown in Table 1, 3 cc of artificial menstrual blood was injected, and absorption speed test and reflux test were carried out.

[0083] The absorption speed test is evaluated by the time (s) until 3 cc of artificial menstrual blood is absorbed, and the reflux test is measured by the following method: After injecting 3 cc of artificial menstrual blood into a sanitary napkin using each sample sheet, place a filter paper under a load of 100 g, and wait for 10 seconds , and when 5 minutes have elapsed, the respective reflux rates were measured.

Abstract

To maintain surface dry feeling and prevent reverse flow in a menstrual time by reducing the accumulation of a body fluid by capillary phenomenon and surface tension on the holed wall part of a surface sheet to rapidly move the body fluid to the hydrophilic second sheet of a lower layer or an adsorbent side in an absorptive article using the surface sheet in which a skin contact surface side is formed of a non-woven fabric and a plastic film layer is laminated on the rear surface of the non-woven fabric. The surface sheet (3) is formed of the non-woven fabric (3A) on the skin contact surface side. The plastic film layer (3B) is laminated on the rear surface of the non-woven fabric (3A), a large number of projected parts and recessed parts are formed on the skin contact surface side by embosses (7), (7), etc., and a large number of open holes (8), (8), etc. are formed on the skin contact surface side. The open holes (8) are formed so that an open hole area for each hole is 0.35 to 0.60mm<2> and an open hole ratio is 10 to 19%. An open hole shape is formed in a hole shape without corner-folded part, for example, in an elliptic shape.

Description

technical field [0001] The present invention mainly relates to an absorbent article used in sanitary napkins, leucorrhea sheets, incontinence pads, medical pads, cosmetics, etc., and more specifically relates to an absorbent article that can quickly absorb body fluids and make the front sheet last An absorbent article that maintains a dry, fluffy feel and reduces reflux after prolonged use. Background technique [0002] Conventionally, absorbent articles such as panty liners, sanitary napkins, and incontinence pads have been known to include the following articles: a liquid-impermeable back sheet such as a polyethylene sheet or a polyethylene sheet laminated with non-woven fabric, and An absorber made of cotton-like pulp or the like is provided between liquid-permeable top sheets such as non-woven fabrics or liquid-permeable plastic sheets. [0003] In the above-mentioned absorbent article, the following structure has been proposed: in order to satisfy the dry feeling to th...
