Abstract

Highquality sportswear should meet certain criteria. Sportswear should be comfortable, which means to enable freedom of movement and a nice touch. The customer expects his clothing to be endurable, that is during its “existence”, to remain the same dimension and be resistant to attrition. One of the main requirements about the sportswear is managing the moisture-fast evaporation and drying, so the body will feel dry and comfortable. The athletes who wear clothes with optimal comfort attain better results. Over the last few years, there has been growing interest in knitted fabrics due to its simple production technique, low costs and high level of clothing comfort. In this paper the influence of the structural properties and the raw content on the thermo physiological comfort, that is, influence on the air permeability, water vapour permeability and thermal characteristics were investigated, as well as the impact on physical-mechanical properties of knitted fabrics for sportswear. The results showed that every knitted structure has different characteristics concerning the thermo-physiological comfort. The knitted structures with higher tightness factor and lower porosity have lower air permeability and water vapour permeability. Double jersey knitted structures, such as interlock and rib have remarkably higher values of thermal conductivity. Knitted structures with higher weight per unit area have higher values of thermal absorptivity. The raw material content has significant influence on the thermal characteristics and water vapour permeability, while its influence on the air permeability is lower concerning the structural characteristics. The results obtained showed that PES single jersey and rib 1:1 cotton knitted structure are marked with the best comfort for underwear; wool and PAN single jersey structures for outer wear against weather influences, and the two-layered knitted structures of cotton/PES will provide the best comfort for tracksuits. Key words: thermo physiological comfort, knitted fabric, structural properties,physical-mechanical properties, air permeability,water vapour permeability, thermal characteristics.
