Thermal and moisture transfer properties of sock fabrics differing in fiber type, yarn, and fabric structure

This study aimed to determine the relative effects of fiber type (fine wool, mid-micron wool, acrylic), yarn type (high-twist, low-twist, single), and fabric structure (single jersey, half-terry, terry) on thermal resistance, water vapor resistance, thermal conductance, water vapor permeability, liquid absorption capacity, and regain of sock fabrics. Fabric structure had the greatest effect on thermal resistance, water vapor resistance, water vapor permeability, liquid absorption capacity, and thermal conductance. Terry fabrics were the most thermal and water vapor resistant, most absorbent, and most conductive. Results were consistent with current understanding of the effect of fabric thickness on thermal and moisture transfer properties when measured under static conditions: However, the effects of yarn type and/or fabric structure of sock fabrics have not previously been explained. © 2014, SAGE Publications.
