Study on Fiber Structure with Ideal Moisture Control Functionality

Abstract: This study investigates specific fabric structures with the optimal moisture transfer properties of moistureabsorbency and dryness depending on the yarn type. Experiments were performed on the moisture absorbency and dry-ness of yarns with different cross sections (four channels, six channels, and regular round), yarn counts (i.e., denier),filament counts, textures (i.e., textured vs. flat), and structures (e.g., double-layer construction with different densitiesbetween the face and back sides). Polyester fiber was identified and determined to fulfill the above functions. Exper-iments were also performed to determine factors that affect the absorbency function of cotton and polyester micropo-rous spun yarns: the yarn count (mono denier), total yarn denier, absorbent chemical concentration, and yarn cross-sectional shape. Finally, experiments were carried out to compare the moisture absorbency and dryness of differentyarn cross sections: four channels, six channels, and regular round.Keywords: polyester, draw texturised yarn, spin draw yarn, moisture absorbency, microporous, moisture management tester
