Problems solved by technology

[0005] However, it is known that when the continuous fiber layer composed of tow is bonded to the front and back by embossing, for example, the space between the fibers becomes smaller due to embossing, which hinders the permeability of body fluids, and at the same time, the temporary storage The ability to retain the body fluid received is reduced, and the original function as the second tablet cannot be fully exerted

Embodiment

[0250] (Experiment 1: Elasticity weakening test)

[0251] The sample is an absorbent body composed of various fiber aggregates made by changing the amount of triacetin as the adhesive (the amount of the adhesive in Comparative Example 1 is is 0)).

[0252] In the test, the thickness of the sample after being dried for 12 hours in a ventilated place adjusted to a temperature of 25 degrees and a humidity of 60% was taken as the thickness before body fluid absorption; after drying, 5cc of horse blood was naturally dripped and absorbed, and then left for 5 minutes The thickness after body fluid absorption was regarded as the thickness after body fluid absorption, and the thickness maintenance rate calculated by (thickness after body fluid absorption) / (thickness before body fluid absorption) was used for evaluation. That is, when the thickness retention rate is high, the elastic force is not weakened, and when the thickness retention rate is low, the elasticity is weakened. The t...

Abstract

It is intended to while satisfactorily exerting the function as a second sheet, prevent 'sticking' by carrying out an embossing of surface sheet. There is provided a humor absorbent article comprising surface sheet (1), liquid permeable member (20) with humor permeability containing a fiber mass of cane and absorption element (AB) with humor retaining capability arranged in this order, wherein second surface-side sheet (10) is interposed between the surface sheet (1) and the liquid permeable member (20) with humor permeability in such a positional relationship that at least part thereof overlaps the liquid permeable member with humor permeability, and wherein the surface sheet (1) and the second surface-side sheet (10) are jointly embossed while the liquid permeable member (20) with humor permeability is not embossed.

Description

technical field [0001] The present invention relates to a bodily fluid absorbent article that can be used for absorbent articles such as disposable diapers, sanitary napkins, urine-receiving pads, and incontinence pads. Especially suitable for sanitary napkins. Background technique [0002] Absorbent articles such as disposable diapers, sanitary napkins, urine-receiving pads, and incontinence pads are generally bodily fluid-absorbent articles in which an absorbent member having bodily fluid-retaining properties is provided on the underside of a top sheet. In the prior art, the absorbent member having bodily fluid retentivity is formed of, for example, cotton-like pulp or synthetic pulp or a sheet-like pulp mixed with an absorbent polymer such as granular powder. However, since the absorbing material composed of these materials is slow in absorbing body fluid, the body fluid will move to the end of the object before being absorbed by the absorbent member, and there is a risk...
