Background

The foreign moisture absorption quick-drying related standards mainly comprise ISO 11092, Japanese JIS L1096 and JISL1907, English BS4554 and American AATCC 79, Taiwan functional textile technical specification FTTS-FA-004 moisture absorption and sweat release textile verification specification and Taiwan textile standard TTF 007 moisture absorption quick-drying textile garment accessories. These standards are applicable to a wide range of test items and methods. A moisture management tester apparatus was independently developed by the university of hong kong tally and applied for american ASTM standards. AATCC subsequently introduced a liquid moisture management characteristic standard for AATCC textile fabrics. The Japanese BOKEN moisture absorption quick-drying test also provides an expensive automatic measuring device, and can meet the standards of JIS L1096 and Japanese multi-family enterprises.

The moisture absorption quick-drying clothes in China are rapidly developed in about 2005, and in order to standardize the market, through a large number of comparison tests, the standard GB/T21655.1-2008' evaluation part 1 of the moisture absorption quick-drying performance of textiles in China is drafted: single combined test method, which is a method standard that is accepted by enterprises internationally at present and can correctly reflect the moisture absorption and quick drying performance of fabrics.

Internationally, the standard similar to the principle specified in GB/T21655.1 in China is accepted comparatively, even if the samples are different in size and different in water content, the samples are hung on a sample rack in the test process, the samples are taken down at intervals of 5min +/-0.5 min in the specified test environment and placed on a balance, the samples are weighed and then hung in the specified test environment through the sample rack again, the test is finished until the change rate of the weighed mass does not exceed 1% for two times, and the water evaporation rate and the evaporation time are calculated.

Because of the need for repeated transfers between the drying chamber and the balance and the sample drift, it is often necessary to hold the sample in a sample holder. In addition, the experiment requires that the sample is spread as much as possible, so that the inaccurate test result caused by different heat dissipation environments of all parts is avoided. The current practice is to clamp the sample on the sample rack by a clamp, and the main defects are as follows: because the water volatilization of the clamping part of the sample is slow, the testing precision is influenced.

In addition, the test requires that the sample holder be held open as much as possible to avoid contact between the sample and the sample holder. The existing sample rack is difficult to meet the requirement.
