Problems solved by technology

That is, before the absorbent article is worn, specifically, when the humidity (relative humidity) is high when the absorbent article is stored, the hygroscopic material may absorb moisture in the atmosphere, and the absorbent article may not sufficiently absorb moisture when worn. question
That is, there is a problem that sufficient moisture absorption performance cannot be exhibited when wearing, and the wearer's discomfort caused by stuffiness and stickiness during wearing cannot be sufficiently suppressed.

Embodiment approach

[0051] Next, the absorbent article 2 according to the second embodiment of the present invention will be described. 2nd Embodiment has the structure similar to the absorbent article 1 except the arrangement|positioning position of the absorber 30 and the hygroscopic material 70 arrange|positioned between the top sheet 10 and the back sheet 20 are different. Thus, using the magnified figure 2 Region A of the cross-sectional view shown is an enlarged view for illustration. Such as Figure 4 As shown, in the absorbent article 2 , the absorbent body 30 includes a polymer absorbent body 80 . Hygroscopic material 70 is arranged inside absorber 30 . Figure 4 The oblique circle marks in represent the polymer absorber 80 . The hygroscopic material 70 and the polymer absorber 80 are contained in the absorber 30 together. As the polymer absorbent 80, generally, a granular polymer such as a sodium acrylate copolymer having absorptivity and hygroscopicity can be used.

Embodiment

[0078] Absorbent articles (Examples 1 and 2) in which 1.0 g of potassium chloride was arranged as a hygroscopic material between a liquid-permeable top sheet and a liquid-impermeable back sheet were prepared, and left for 72 hours under conditions assumed to be stored. As a comparative example, an absorbent article (Comparative Examples 1 and 2) in which 1.0 g of a polymer absorbent was arranged between a liquid-permeable top sheet and a liquid-impermeable back sheet was prepared and placed under the same conditions. The results are shown in Figure 9 .

[0079] Among them, the assumed storage condition 1: temperature 20°C / humidity 80RH%

[0080] Presumed storage conditions 2: temperature 30°C / humidity 80RH%

[0081] In addition, the absorbent articles of Examples 1 and 2 were left for 72 hours on the condition that they were supposed to be worn. The absorbent articles of Comparative Examples 1 and 2 were placed under the same conditions. The results are shown in Figure ...

Abstract

An absorbent article (1) is provided with an absorbent body (30) between a liquid-permeable top sheet (10) and a liquid-impermeable back sheet (20), and the absorbent body (30) has a function as a hygroscopic material. Granules of electrolytes. Therefore, sufficient moisture absorption performance is exhibited during wearing, and the wearer's discomfort caused by stuffiness, stickiness, and the like can be more reliably suppressed.

Description

technical field [0001] The present invention relates to an absorbent article equipped with a top sheet, a back sheet and an absorbent body. Background technique [0002] In the past, absorbent articles such as sanitary napkins were generally equipped with a liquid-permeable surface sheet that contacts the wearer's skin and allows body fluids such as menstrual blood excreted from the wearer to pass through, and a body-fluid-impermeable surface sheet. A liquid-impermeable back sheet, and an absorbent body arranged between the top sheet and the back sheet to absorb bodily fluids. [0003] In such absorbent articles, in order to suppress the wearer's discomfort caused by stuffiness and stickiness when wearing, it is known that a hygroscopic material using a high-molecular polymer with high water absorption is compounded on the absorbent body. (eg, Patent Document 1). [0004] prior art literature [0005] Patent Document 1: JP-A-6-511278 (pp. 3-4, figure 1 ) Contents of th...
