Abstract
Abstract Socks’ comfort has vast implications in our everyday living. This importance increased when we have undergone an effort of low or high activity. It causes the perspiration of our bodies at different rates. In this study, plain socks with different fiber composition were wetted to a saturated level. Then after successive intervals of conditioning, these socks are characterized by thermal resistance in wet state at different moisture levels. Theoretical thermal resistance is predicted using combined filling coefficients and thermal conductivity of wet polymers instead of dry polymer (fiber) in different models. By this modification, these mathematical models can predict thermal resistance at different moisture levels. Furthermore, predicted thermal resistance has reason able correlation with experimental results in both dry (laboratory conditions moisture) and wet states.
Highlights
Consumers consider comfort as one of the most important attributes in their purchase of apparel products; companies tend to focus on the comfort of apparel products
By adopting the new approach of feeding wet polymer filling coefficient and thermal conductivity instead of dry polymers, different models can make a reasonable prediction of thermal resistance in wet states as well
All the models have a coefficient of determination (R2) >0.78
Summary
Consumers consider comfort as one of the most important attributes in their purchase of apparel products; companies tend to focus on the comfort of apparel products. Clothing comfort has two main aspects that combine to create a subjective perception of satisfactory performance: thermo-physiological and sensorial. The thermo-physiological relates to the way clothing safeguards and dissipates metabolic heat and moisture [2,3], whereas the sensorial relates to the interaction of clothing with the senses of the wearer [4,5]. Thermal-wet comfort being the strongest among tactile and pressure comfort perceived by subjects during exercise [6]. Dry heat transfer occurs through conduction, radiation, convection, and ventilation, whereas wet heat transfer when sweating includes several additional complex processes including evaporation, wicking, sorption and desorption, wet conduction (additional conductive heat transfer due to the clothing being wet), and condensation of moisture [7,8]
