Abstract:V prispevku je predstavljeno vrednotenje toplotnih lastnosti ploskih tekstilij in njihovih kombinacij, namenjenih za poslovna oblačila, ki je potekalo v dveh delih. V prvem delu so bile raziskane toplotne lastnosti ploskih tekstilij ovrednotene na različnih merilnih napravah, ki omogočajo merjenje prehoda toplote in/ali prehoda vodne pare skozi plosko tekstilijo, in sicer s pomočjo toplotne plošče ter merilnih naprav Thermo Labo II in Permetest. V tem delu raziskave so bile raziskane povezave med lastnostmi ploskih tekstilij oziroma odvisnosti med posameznimi parametri toplotnih lastnosti analiziranih ploskih tekstilij, izmerjenimi na različnih merilnih napravah ter odvisnosti med toplotnimi lastnostmi in debelino tekstilije. V drugem delu raziskave so bile raziskane toplotne lastnosti kombinacij posameznih ploskih tekstilij in sicer s pomočjo toplotnega cilindra s simulacijo znojenja, ki omogoča merjenje prehoda toplote in prehoda vodne pare skozi tekstilije ali kombinacijo tekstilij. Za ta namen je bil raziskan vpliv klimatskih razmer in stopnje znojenja na toplo-tne lastnosti posameznih kombinacij ploskih tekstilij. Raziskava je pokazala, da med parametri toplotnega upora, izmerjenega s toplotno ploščo, ter merilnima napravama Permetest in Thermo Labo II, obstajajo statistično pomembne korelacije, in da med toplotnim uporom, določenim iz kvocienta debeline in toplotne prevodnosti, dobljene z merilno napravo Thermo Labo II ter toplotnim uporom, dobljenim s toplotno ploščo in z merilno napravo Permetest prav tako obstaja korelacija. Potrjeno je, da se z naraščajočo debelino materiala vrednosti toplotnega upora in upora proti prehodu vodne pare ploskih tekstilij povečujejo. Hkrati je bilo ugotovljeno, da različne klimatske razmere in stopnje znojenja vplivajo na toplotne lastnosti kombinacij ploskih tekstilij. Ugotovljeno je bilo, da so toplotne lastnosti, tj. suhi in evaporativni toplotni tok ter sposobnost prehoda vodne pare odvisne od klimatskih razmer oziroma temperaturnega gradienta med površino cilindra in temperaturo zraka, in da se z različno stopnjo znojenja, vrednosti evaporativnega toplotnega toka, korigiranega toplotnega upora in sposobnosti prehoda vodne pare spremenijo.

Title:Evaluation of textile thermal properties and their combinations
Abstract:The paper presents the evaluation of textile material thermal properties and their combinations as used for business clothing systems, which was conducted through two separate studies. In the first study, an investigation of textile thermal properties was carried out using different measurement systems enabling the measuring of heat and/or moisture transmission through textile materials by using the hot-plate apparatus, the Thermo Labo II and the Permetest measurement systems. This part of the research investigated the correlations between the measured parameters of the textile thermal properties evaluated by using different measurement systems, and correlations between thickness and thermal properties. In the second study, the thermal properties of material combinations were evaluated by using a thermal sweating cylinder enabling the evaluation of heat and moisture transmission through textile materials or material combinations. The influences of different environmental conditions and sweating levels on the thermal properties of material combinations were investigated for this purpose. The results show that statistically significant correlations exist between the parameters of textile thermal resistances evaluated with different measurement systems using the hot-plate apparatus, the Thermo Labo II and the Permetest measurement systems. It is also evident from the results that by increasing textile thicknesses, the values of textile thermal resistances and water vapour resistance increase proportionally. The results of evaluating thermal properties of material combinations under different environmental and sweating conditions showed that different climate conditions and sweating levels influence the heat and moisture transmission properties of material combinations. The results show that dry and evaporative heat loss and water vapour transmission depend on climatic conditions or temperature gradient, respectively, between the cylinder surface and ambient temperature, and that different sweating levels influence the evaporative heat loss, corrected thermal resistance and water vapour transmission values.
