Embodiment 1

[0086] Next, the dimensions in the stretched state and the dimensions in the natural state of the absorbent article according to the embodiment were measured. The number of samples (N) is 5. The individual dimensions were determined for each sample.

[0087] The absorbent article in the stretched state after stretching the stretchable member was measured by the following method. Here, the state where the elastic member is stretched refers to the state where the waist elastic member, the waist elastic member, the leg elastic member, and the leg side elastic member are stretched, and more specifically, it means that the absorbent article is stretched from the natural state. Wrinkles caused by the elastic member cannot be visually confirmed.

[0088] When the absorbent article is enclosed in a packaging bag, etc., take it out of the packaging bag and use the environment at (20-2~20+2)°C and relative humidity (60-5~60+5)%RH in the current state Samples obtained after 12 hours o...

Embodiment 2

[0098] Next, the wearing feeling at the time of wearing was compared and evaluated using the absorbent article which concerns on an Example and the absorbent article which concerns on a comparative example. Table 2 shows the comparative evaluation results of absorbent articles. As shown in Table 1, the test was implemented about the pants type sanitary napkin which concerns on Example 1 and Comparative Examples 1-3.

[0099] 【Table 2】

[0100]

[0101] In the comparative evaluation test, 20 women who normally use pant-type sanitary napkins were asked, "About the feeling of stuffiness when wearing them, do you feel uncomfortable due to stuffiness?"

[0102] Regarding this question, the samples whose answer to the following (1) exceeds 70% were rated as ◯, indicating that the response evaluation was good. In addition, the sample whose number ratio of answering (1) below was less than 70% was evaluated as ×, and it showed that the response evaluation was not good enough.

Abstract

The invention provides a determination method for blood absorption amount and further for indexing body fluid imbedibility of an absorbent article. The determination method for blood absorption amount is used for determining blood absorption amount of the absorbent article with an absorption body and a surface sheet material. The determination method for blood absorption amount comprises: determining a target object, specifically utilizing a clamping member to clamp the absorbent article without clamping the absorption body; putting a determination solution into a container, and submerging the determination target object into the determination solution by enabling the surface sheet material to face upwards; immersing the determination target object in the determination solution for a preset time, and taking out the determination target object; and suspending the determination target object for a preset time by utilizing the above clamping member.

Description

technical field [0001] The invention relates to a method for measuring blood absorption. Background technique [0002] Patent Document 1 and Patent Document 2 disclose an absorbent article including an absorbent main body having an absorber and an exterior body disposed outside the absorbent main body. The purpose is to suppress the leakage of body fluids. [0003] The absorbent article of Patent Document 1 is configured to suppress leakage by suppressing migration of a superabsorbent polymer. In addition, the absorbent article of Patent Document 2 is configured to suppress leakage of excrement by suppressing swelling of the absorbent core toward the skin surface side during liquid absorption. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2011-15886 [0005] Patent Document 2: Japanese Patent Laid-Open No. 2011-24888 [0006] However, in the above-mentioned absorbent articles, depending on the absorbing performance of the absorber, the absorbability of bodily...
