A New Wicking Performance Test in Textile Fabrics to Simulate Realistic Human Sweating with Continuous Microfluidic Flow

摘要

Typical liquid moisture management property tests of textiles such as vertical wicking test (AATCC 197) and moisture management test (AATCC 195) are conducted with infinite reservoirs or limited, but large amounts of liquid. Therefore, those methods may not represent human sweating circumstances with continuous microfluidic flow from sweat pores. Even though a fabric received a favorable evaluation from these typical wicking tests, we cannot be sure the fabric would remove sweat well in realistic physiological sweating conditions. In terms of textile structures, typical wicking tests could not explain how yarn-level wicking plays a role within the fabric, even though liquid transport in the void space between the fibers within a yarn (or between yarns) is known as the most critical phenomenon in fabric wicking.
