New Test Method for Measuring the Cooling Provided by Wicking Liquid Moisture and Evaporating it from Clothing Materials Using a Sweating Hot Plate
1. Scope
This test method covers the measurement of cooling energy that is felt on the skin when water is wicked into a fabric and evaporated into the environment. This measurement occurs during active sweating and during a drying phase to fully characterize the fabric.
Keywords
Wicking, Sweating hot plates, Cooling, drying,
Rationale
Currently, many products are being sold indicating that it provides cooling without any data to show that it enhances heat release. All claims are made based on the fact that material picks up liquid moisture and spreads it out to provide quicker evaporation and therefore more cooling. This method will take the guesswork out of this and actually measure the amount of cooling provided during active sweating and in drying. A cooling efficiency value will also be provided that compares the cooling back to the maximum amount of cooling found on bare skin.
The title and scope are in draft form and are under development within this ASTM Committee.
