Problems solved by technology

However, there is a problem that the softness of the liquid-absorbent pad (absorbent body) will be impaired due to the heat-welding fibers of the absorption and retention layer and the non-woven fabric layer, and further improvement is required.

Embodiment

[0066] Nonwoven fabrics of Examples 1 to 3 and Comparative Examples 1 to 3 shown below were produced, and the fluff height measurement and tensile test thereof were performed. In addition, a diaper-type sample having an absorbent body 4 using these nonwoven fabrics was produced, and the effect of suppressing shape collapse of the liquid-absorbent mixture 5 was confirmed.

[0067] The non-woven fabrics produced are all made of long fibers with a core-sheath structure with polypropylene (PP) as the core by the spunbond method. Polyethylene (PE) with different melting points is used for the sheath of the fiber. By changing the temperature of the heat welding, the strength of the heat welding is different, thereby adjusting the height of the fluff. In addition, the fiber diameter of the long fibers is 20 to 25 μm.

[0068] More specifically, as shown in Table 1, in Example 1, PE with a melting point of 125°C was used as the material of the sheath to produce a sheath with a mass o...

Abstract

It is intended to provide an absorbing article in which a liquid-absorbing mixture is prevented from deformation. An absorbing article wherein an absorbing body comprising a liquid-absorbing mixture consisting of super-absorbing polymer particles and a fluff pulp and a nonwoven fabric made of thermoplastic resin long fibers are provided between a liquid-permeable sheet and an outer-covering sheetfacing the liquid-permeable sheet, characterized in that the nonwoven fabric is in contact in at least one face thereof with the liquid-absorbing mixture, has joint points at which long fibers are joined to each other at intertwining points, and has a raising height defined as the difference (Tb-Ta), wherein (Ta) stands for the thickness before a raising test while (Tb) stands for the thickness after the rising taste, of 0.5 mm or more.

Description

technical field [0001] The present invention relates to absorbent articles. Background technique [0002] An absorbent body in which a mixture of superabsorbent polymer particles and fluff pulp (fluff pulp) is covered with tissue paper is used for absorbent articles such as disposable diapers and sanitary napkins. In such an absorbent body, when only superabsorbent polymer particles and fluff pulp (hereinafter referred to as a liquid-absorbent mixture) are mixed, the absorbent body may be twisted or bent due to the movement of the wearer. Therefore, the shape of the liquid-absorbent mixture collapses. [0003] Patent Document 1 discloses a disposable wearing article in which a liquid-absorbent pad (absorbent body) is composed of an absorbing and retaining layer (liquid-absorbent mixture) having a plurality of recesses recessed in the thickness direction and containing heat-welding fibers. It is composed of a non-woven fabric layer arranged on the upper surface of the absor...
