Embodiment 1

[0035] combined with figure 1 , the present embodiment provides a method for measuring the air permeability of a paper diaper product, comprising the following steps:

[0036] S1. Pre-place the diaper product to be tested in an environment with constant temperature and humidity for at least 2 hours;

[0037] S2. Prepare artificial urine for testing paper diaper products;

[0038] S3. Using a preset amount of artificial urine to flow onto the surface of the diaper product 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 diaper product to be tested in an environment with constant temperature and humidity for at least 2 hours in advance, the influence of temperature and humidity in the environment on the diaper product to be test...

Embodiment 2

[0043] In the method for measuring the air permeability of a paper diaper product 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, where Q is Arithmetic mean value of air flow, S is the test area of ​​air circulation during the experiment.

[0044] In step S3, at least 5 copies of samples to be tested are prepared for each type of diaper, and the corresponding air flow values ​​are respectively obtained through the detection of the fabric air permeability tester, and then calculated according to the calculation formula R=Q / S*167 The air permeability of the sample to be tested, wherein the unit of the air permeability R is mm / s. Compared with the existing method for measuring the air permeability of paper diapers, this method can accurately obtain the air permeability of paper diapers, and more intuitively reflect the air permeability of paper diapers.

Embodiment 3

[0051] In the method for measuring the air permeability of a paper diaper product in this embodiment, compared with the technical solution in Embodiment 1, in step S4, the fabric air permeability tester operates at an air pressure of 450-550Pa and a test area of ​​5-50cm 2 Calibrated under the conditions. The fabric air permeability tester calibrated under this condition can ensure that the speed of air circulation and the amount passing through the surface of the sample to be tested are closer to the actual use situation, and further improve the test accuracy of the sample to be tested.

[0052] In actual use, the fabric air permeability tester includes a detection unit, a control unit, an air injection unit and a fixing device, the control unit is electrically connected to the detection unit and the air injection unit respectively, and the control unit is used to control the detection unit and the air injection unit , the detection unit is used to detect the air flow rate pa...

Abstract

The invention discloses a method for measuring the air permeability of a paper diaper product, and relates to the technical field of hygienic product detection. The method comprises the following steps of: S1, placing a to-be-detected paper diaper product in an environment with constant temperature and humidity for at least 2 hours in advance; S2, preparing artificial urine for testing the paper diaper product; S3, enabling a preset amount of artificial urine to flow to the surface of the to-be-detected paper diaper product so as to form a to-be-detected sample; S4, detecting the air flow value of the to-be-detected sample by adopting a fabric air permeability tester; and S5, calculating the air permeability of the to-be-tested sample according to the air flow value. The measurement method is simple to operate and quick in response, can accurately measure the air permeability of the paper diaper product, greatly improves the measurement accuracy, and more intuitively reflects the air permeability of the paper diaper product in a moisture absorption state.

Description

technical field [0001] The invention relates to the technical field of hygienic products detection, in particular to a method for measuring the air permeability of paper diapers. Background technique [0002] Paper diapers are one-time-use products, which are mainly used by people who cannot control excretion independently and are not easy to move, such as children and the elderly. There are many types of diapers on the market, and the performance of each diaper is different. There are many performance factors that affect the use of diapers, and air permeability is one of them. Paper diapers with poor air permeability will form a hot and humid environment after defecation, which will cause a large number of bacteria to grow, causing skin discomfort and prone to skin rashes and other symptoms. Therefore, it is very important to test the air permeability of paper diapers before using them. However, the current test methods for the air permeability of paper diapers are cumbers...
