Abstract

The invention relates to a method of testing the textile dynamic heat-moisture transmission performance, which comprises the following steps: the environmental conditions are set, the whole test is carried out in an artificial climate simulation chamber, and the environmental temperature, the relative humidity and the wind speed required by the test are set; a sample is damped and balanced for 24 hours in advance under the condition of secondary standard and is then put into the artificial climate simulation chamber which is well set; the temperature of simulating skin is kept at 35 DEG C, and the perspiration volume is set into saturated perspiration volume, namely, the simulating skin is moistened completely; the distance between the testing textile and the simulating skin is 10mm, a group of temperature and humidity sensors are arranged in the center of the microclimate, and the distances between the sensors and the sample as well as between the sensors and the simulating skin are both 5mm; the testing is carried out; and testing result data is collected and analyzed. Compared with the prior art, a heat-moisture collecting system can accurately collect the continuous curve of the temperature and the moisture in the simulating microclimate at real time along with the change of time and is convenient for testing, analyzing and comparing the dynamic heat-moisture transmission performance of the textile.
