Abstract

Toplotne i fiziološke komponente su primarne funkcionalne komponente odeće, zbog toga što odeća mora da obezbedi zaštitu od hladnoče i toplote, i mora da dozvoli transfer vlage i toplote kroz različite slojeve odeće. U radu su konstruirane i ispletene dvoslojne integrirane pletenine od pamučne pređe u apsorpivnom sloju (lice pletenine) i od poliamidnih odnosno poliesterskih filamenata u difuzijskom sloju (naličje pletenine). Ispitivan je uticaj sirovinskog sastava i strukturnih karakteristika pletenina na toplotna svojstva (toplotnu provodljivost, toplotnu apsorpciju i toplotnu otpornost), kao i propustljivost vodene pare i vazduha pletenina. Toplotna svojstva ispitivana su metodom dr Bok-a. Strukturne karakteristike imaju značajan uticaj na toplotna svojstva i propustljivost vode i vazduha. Dvoslojno - integrirane pletenine sa poliamidnom komponentom daju hladniji osečaj u dodiru sa kožom, zbog njihove manje vrednosti toplotne apsorpcije. Ključne reči: dvoslojne integrirane pletenine, termo-fizološki komfor, propustljvost vodene pare, propustljivost vazduha THERMAL-PHYSIOLOGICAL COMFORT OF INTEGRATED DOUBLE KNITTED FABRICS The thermal and physiological components which have historically been the primary functional component of clothes, since they must protect us from cold and heat and, simultaneously, have to allow an appropriate moisture and heat transfer through the different layers. In this paper, integrated double layer knitted structures have been constructed and knitted, using cotton yarn in absorption (face) and polyamide or polyester filaments in diffusion (back) layers of the fabrics. The influence of the raw material used and the structural characteristics of the knitted structure on the thermal properties (thermal conductivity, thermal absorptivity, thermal conductivity) and permeability to water vapour and air has been statistically investigated. The thermal properties of fabrics have been tested using method of dr Bok. The structural characteristics have significant influence on the thermal properties and water and air permeability. Double – layer knitted structures with polyamide filaments has given a colder feeling based on higher thermal absorptivity values. Key words: double-integrated knitted fabrics, thermal-physiological comfort, water vapour permeability, air permeability
