specific Embodiment

[0062] The moisture permeability of the three fabrics was tested with the above test methods. The tested fabrics were cotton fabrics, polyester-cotton blended fabrics and wool-polyester blended fabrics. The test environment temperature was controlled at 30°C, flow controllers, temperature and humidity transmitters The instrument, thermocouple and data acquisition unit are selected from conventional instruments. Each sample is tested three times, and the arithmetic mean value of the three times is taken as the final test result. The test results are shown in Table 1 and Table 2. Table 1 shows the moisture permeability of the tested fabric. Amount, Table 2 is the total diffusion resistance of the tested fabric. It is not difficult to see that the variation coefficients of the moisture permeability and total diffusion resistance of the three samples are less than 1%, which shows that the repeatability of this fabric moisture permeability test method is good. Because the fabric mo...

Abstract

The invention relates to a testing device and the method for the fabric moisture-penetrability. The device is made up of the column canister, the base, the waterproof moisture film, the pressure ring and the testing board. The shallow groove is set on the base which the two ends are connected with the air inlet and the air outlet carved on the base two sides. The waterproof moisture film is the bottom of the column canister to form the saturate water vapor resource; the dry quick flowing N2 is the carrier to carry the water vapor through the fabric away. So it can measure the relative humidity of the N2 flow to get the moisture content of the fabric. The invention has the high precision and good repetition, the testing time is short and the cost is low; so the device can be used in the textile mill to control the product moisture-penetrability quality.

Description

technical field [0001] The invention relates to a fabric moisture permeability test device and a test method, belonging to the field of textile engineering. Background technique [0002] With the development of social economy and the improvement of people's living standards, people have higher and higher requirements for the comfort of textiles. The heat and humidity comfort of clothing is the most important aspect of its comfort. The moisture permeability of fabrics is the key to the heat and humidity comfort of clothing an important part of evaluation. In the complex system of human body, clothing and environment, the thermal and moisture comfort of the human body depends on the balance between the heat generated by itself and the heat lost to the environment. The human body not only dissipates heat to the surrounding environment through conduction, convection, and radiation, but also loses heat through the evaporation of sweat on the surface of the human skin. If the wa...
