Comfort of Socks Made of Innovative Cellulose Materials

The socks are knitted next-to-skin-type garments worn on the feet and often covering the ankle and some part of the calf. They have to fulfill high demands of functionality, comfort, durability and design. As the comfort of socks depends on their construction and materials used, it is very important to select fibers and yarns for their production. The number of European standards related to testing of knitwear and socks are low. With increasing demand for garment comfort, there are many studies related to the comfort properties of fabrics. However, there are significantly less studies examining the thermal comfort of socks, which are using thermal foot model. The socks are usually made from cotton yarns for softness and comfort and blended with polyamide or Lycra for improved fit, durability and shrink resistance. Therefore, and with the fact that the applicability of modal fibers and microfibers (man-made artificial fibers from cellulose which provide silky touch and exceptional contact comfort) in knitting of socks is insufficiently researched, as well as yarns made from them by unconventional rotor and air-jet process, in this paper properties of two groups of socks, made of innovative materials – single ring, rotor and air- jet spun yarns of the same linear density (all made of bright staple modal fibers of linear density of 1.3 dtex and modal microfibers of 1.0 dtex respectively) in full plating by textured polyamide 6.6 yarns of different linear density were evaluated. Evaluation of sock comfort was carried out by investigation of water vapor absorption and air permeability of socks knitted fabrics and socks thermal comfort before and after five repeated washing and drying cycles by measuring of thermal resistance on the thermal foot.
