This study examines the liquid moisture transfer properties of a selected group of heat-resistant workwear fabrics using a demand wettability test. The Gravimetric Absorbent Testing System procedure is modified and developed to assess the effects of wicking finish treatment and hygroscopic fibers on workwear fabrics. Unlike the simple vertical method of measuring wicking, the procedure adopted in this study produces informative results for moisture management characteristics and wearer comfort of textile materials. The absorption capacity, instantaneous rate of absorption, and evaporation/absorption ratio of five different heat-resistant workwear fabrics are determined and discussed. Results show that the wicking treatment of aramid fabrics noticeably increases their rate of absorption but does not affect their absorption capacity and water vapor absorption. The flame resistant rayon blends have improved vapor absorption properties but adversely affected liquid moisture management properties. Since the cotton fabric shows the highest percentage of remaining water after the evaporation test, a garment made of this fabric may generate a clammy feeling despite its superior absorbent capacity and rate of absorption.
