Problems solved by technology

[0006] However, since the bulk density of the absorbent body (pulverized pulp) is greatly increased in articles that are thinned by press processing the absorbent body, the absorbent body becomes hard and the wearer feels a firm feeling.
In addition, since the thickness of the cellulose flocs is increased after production, or the absorbent body becomes thinner and more superabsorbent resin is mixed in, there are problems that the cellulose flocs tend to shift or break, etc.
Furthermore, as the density of the absorber increases, the diffusion of body fluids due to capillarity increases, and there is also a problem that there may be a sense of insecurity with respect to lateral leakage in the short side direction (width direction) of the absorber.

Embodiment

[0059] Produced various printed samples, measured the WC value (compression energy) as an index value for softness, and measured the above-mentioned tensile strength as an index value for the difficulty of cellulose floc shifting, and the results are shown in the graph of Fig. 9 . In the figure, the softness of the skin becomes stronger toward the right side, and the cellulose fluff is less likely to be shifted toward the upper side. For the 4 samples shown in this embodiment, it can be seen that the WC value (compression energy) obtained by the KES compression tester is 0.8gf·cm / cm 2 The conditions above and the wet tensile strength of 0.4N or more can be satisfied in a well-balanced manner to prevent cellulose floc shifting and cellulose floc rupture in the absorbent body.

Abstract

The present invention provides an absorbent article which can give softness to the skin when worn even if it is a thin absorbent article, and which can prevent the shifting of cellulose wadding and the breakage of cellulose wadding in an absorbent body. An absorbent article 1 comprising an absorbent body 4 interposed between a liquid-permeable top sheet 3 and a liquid-impermeable back sheet 2, wherein thermally-bonded fiber layers are arranged on the upper side and the lower side of the absorbent body 4, respectively. 6, 6, by applying a plurality of linear prints 7, 7 ... formed in the direction along the substantially longitudinal direction of the absorbent article 1, the thermally weldable fiber layer disposed on the upper surface side of the absorbent body 4 6 and the thermally weldable fiber layer 6 disposed on the lower surface side of the absorber 4 are bonded to each other.

Description

technical field [0001] The present invention mainly relates to an absorbent article used for sanitary napkins, leucorrhea sheets, incontinence pads, medical pads, cosmetics, etc. , can also maintain a soft feeling relative to the skin, and prevent the occurrence of cellulose fluff shifting or cellulose fluff breaking absorbent articles. Background technique [0002] Conventionally, absorbent articles such as sanitary pads, sanitary napkins, and incontinence pads have been known to include the following: a liquid-impermeable reverse sheet such as a polyethylene sheet or a polyethylene sheet laminated with a non-woven fabric, and a non-woven fabric Alternatively, an absorbent body composed of cellulose flocks (mixed with a superabsorbent resin) such as pulverized pulp is interposed between liquid-permeable surface sheets such as liquid-permeable plastic sheets. [0003] In recent years, for bulky absorbent articles, there are problems that they are not suitable for carrying o...
