A device for testing the moisture loss rate of textiles with controlled water supply

Abstract

The present invention relates to a kind of testing device of the moisture dissipation rate of textiles with controlled water supply, which is characterized in that it comprises a sample rack and a buffer table for carrying samples, most of the sample area is located on the sample rack, and the upper surface of the sample rack is in contact with the sample. The area is the dehumidification area, a small area of ​​the sample is located on the buffer table, the area where the upper surface of the buffer table is in contact with the sample is the water absorption area, and the upper surface of the sample holder is flush with the upper surface of the buffer table. The invention discloses a test device for the moisture dissipation rate of textiles with controlled water supply. The device can supply water continuously and at a constant speed, and can effectively control the moisture dissipation area of ​​the fabric, so as to ensure that the fabric is in a constant and controllable moisture dissipation state during the test. The evaporation rate is affected by the reduction of moisture in the fabric. In addition, the device can automatically record the test results, which has the advantages of high efficiency and small error.

Description

Technical field [0001] The present invention relates to a wet rate measuring device for textile generalization, belonging to the technical field of textile performance testing. Background technique [0002] In traditional methods, researchers often use WER methods to measure the moisture evaporation rate of fabrics. Its experimental step is that in a no-air environment of temperature 20 ± 1 ° C and relative humidity, 30% water is taken on the center of a plastic plate, and then cover the back surface of the test On the water droplets, the entire plastic plate and the abutment are placed on the electronic balance. As the moisture evaporation, the mass change is recorded, the moisture evaporation rate of the fabric is finally calculated from 30 min and 60 min, and the calculation formula is Wer (%) = The moisture mass of the evaporated moisture / drop is added.

Problems solved by technology

In addition, since the amount of water supplied is fixed, it is impossible to guarantee the constant moisture dissipation area of ​​the fabric during the test, because different fabrics have different absorption and conduction effects on moisture, so the diffusion area of ​​the same volume of water on the surface of different fabrics is different, and the moisture content is different. The diffusion area is equivalent to the moisture dissipation area of ​​the fabric during the test

Since the indicators measured by the existing test methods do not meet the definition of fabric moisture dissipation rate, they cannot be used to characterize the fabric moisture dissipation rate

[0006] In addition, there are too many manual interventions in the existing test methods, and the fabric will be affected by unstable human factors during the frequent weighing process. Stained on the container, etc., these factors will cause errors in the test and affect the validity and accuracy of the test
