Abstract:

This paper presents a study on the air permeability of socks manufactured using the yarns of new kinds of fibres, such as soybean, bamboo, cotton/seacells and bamboo/flax. The air permeability of plain pure knits and plated knits of textured polyamide (PA) and elastane (Lycra) wrapped with textured polyamide threads was investigated. It was determined that higher air permeability is characteristic for knits produced from natural yarns, a lower permeability for knits with textured PA, and the lowest for knits with Lycra threads. Textured PA or Lycra threads change the structure of plated knits as the construction of such knits are thicker and tighter. The variation in air permeability depending on the area density, linear density, loop length and tightness factor of plain and plated plain knits was discused.
