Embodiment 1

[0035] combined with figure 1 , the present embodiment provides a method for measuring the air permeability of sanitary napkins, which comprises the following steps:

[0036] S1. Place the sanitary napkin to be tested in a constant temperature and humidity environment for at least 4 hours;

[0037] S2, preparing artificial menstrual blood;

[0038]S3. Flow a preset amount of artificial menstrual blood into the surface of the sanitary napkin to be tested to form a sample to be tested;

[0039] S4, using a fabric air permeability tester to detect the air flow value of the sample to be tested;

[0040] S5. Calculate the air permeability of the sample to be tested according to the air flow value.

[0041] In this embodiment, by placing the sanitary napkin to be tested in an environment of constant temperature and humidity for at least 4 hours in advance, the influence of temperature and humidity in the environment on the sanitary napkin to be tested can be effectively avoided, ...

Embodiment 2

[0043] Compared with the technical solution of Example 1, the method for measuring the air permeability of a sanitary napkin in this embodiment, steps S2-S5 are all carried out under the environment of constant temperature and humidity described in step S1, wherein the constant temperature The environment with high humidity refers to the environment with a temperature of 20-25 degrees and a relative humidity of 45%-55%. This setting can effectively reduce the influence of temperature and humidity in the environment on sanitary napkins and the results of subsequent testing.

Embodiment 3

[0045] In the method for measuring the air permeability of a sanitary napkin in this embodiment, compared with the technical solution in Example 1, in step S5, the air permeability of the sample to be tested is calculated according to R=Q / S*167, wherein Q is air The arithmetic mean value of the flow rate, S is the test area of ​​the air circulation during the experiment. In step S3, prepare at least 5 copies of the samples to be tested for each sanitary napkin, and obtain the corresponding air flow values ​​through the detection of the fabric air permeability tester, and then calculate the samples to be tested according to the formula R=Q / S*167. Measure the air permeability of the sample, where the unit of the air permeability R is mm / s. Compared with the existing method for measuring the air permeability of the sanitary napkin, the method can accurately obtain the air permeability of the sanitary napkin, and more intuitively reflect the air permeability of the sanitary napkin...

Abstract

The invention discloses a sanitary towel air permeability measuring method, which relates to the technical field of hygienic product detection. The sanitary towel air permeability measuring method comprises the following steps of S1, placing a sanitary towel to be detected in a constant temperature and humidity environment for at least 4 hours, S2, preparing artificial menstrual blood, S3, enabling a preset amount of artificial menstrual blood to flow into the surface of the sanitary towel to be detected so as to form a sample to be detected, S4, detecting the air flow value of the sample to be detected by adopting a fabric air permeability tester, and S5, calculating the air permeability of the sample to be detected according to the air flow value. According to the measuring method, the real use condition is simulated, the sanitary towel absorbing liquid is detected by the fabric air permeability tester to obtain the air flow value, the air permeability of the sanitary towel absorbing liquid can be intuitively reflected, and the measured air permeability is high in accuracy.

Description

technical field [0001] The invention relates to the technical field of sanitary product detection, in particular to a method for measuring the air permeability of sanitary napkins. Background technique [0002] Sanitary napkin is an absorbent material, the main material is polymer and polymer composite paper formed by polymer water-absorbent resin, non-woven fabric, fluff pulp or a composite of the above materials, belonging to the female group daily necessities. There are many kinds of sanitary napkins on the market at present, and the performance of various sanitary napkin products is also different. There are many performance factors that affect the use effect of sanitary napkins, and air permeability is one of them. Sanitary napkins with poor air permeability, especially in summer, women are prone to sweating during menstruation. If the amount of menstrual blood is heavy, the moisture and sweat cannot be discharged in time, and it is easy to form a humid and hot environ...
