3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
wetting time
T
time from the liquid comes into contact with the surface of textile to the time it takes for the textile to begin absorbing moisture. It is expressed as the time when the first occurrence of the slope is greater than or equal to tan15° on the relationship curve between moisture content and time
3.2
absorption speed
A
increase rate of moisture content per unit time of textile. The average value of the slope of moisture content change curve during the test time.
