Socks are considered to be one of the important accessories for humans in everyday life. Socks undergo irregular stretching in multiple directions during usage. The amount of stretching that occurs in socks is proportionate to the level of foot movement and the foot shape. The comfortability of socks lagely depends on the air permeability and thermal comfort properties. In general, the air permeability of the socks was measured in unstretched conditions. However, in real-time situations, the socks get stretched in multiple directions while being used. Stretch is one of the key factors that largely influences the air permeability of the socks. Few researchers have addressed this area; hence, the air permeability of the socks under various percentages of stretch is primarily focused on in this study. A novel automated fabric stretching attachment device was used to study the effect of stretching on the air permeability of recycled polyester/ virgin cotton and its blended socks. The results were statistically investigated by two-way analysis of variance by using SAS 8.0. A statistical analysis proved that the effect of the stretching and blend ratio was statistically significant on the air permeability properties of socks.
