1 24 The Thermal Comfort Properties of Surgical Gown Fabrics Termofiziološke lastnosti udobnosti kirurških oblačil za enkratno in večkratno uporabo december 2008 marec 2009 Izvleček Kirurška oblačila se uporabljajo za zaščito pacientov in kirurške ekipe pred okužbo med samo operacijo. Prvotno so bila izdelana le iz bombažnih tkanin, danes pa se za njihovo izdelavo uporabljajo različne vrste tkanin in netkanih tekstilij. Namen te raziskave je bila ocena termofizioloških lastnosti udobnosti različnih tekstilij, ki se uporabljajo za izdelavo kirurških oblačil. Analiza je bila izvedena na osmih kirurških oblačilih, ki so dostopna na tržišču; na treh netkanih tekstilijah (Spunlace, SMS, Spunbond) in petih tkaninah (100 % bombaž, 50 % poliester 50 % bombaž, 65 % poliester 35 % bombaž, 66 % poliester 33 % bombaž 1 % ogljikova vlakna, 99 % poliester 1 % ogljikova vlakna). S preskuševalno opremo za določitev termofizioloških lastnosti Alambeta so bile določene toplotna prevodnost, absorpcija toplote in toplotna upornost tekstilij. Izmerjena je bila debelina tekstilij in določena korelacija med debelino in toplotno upornostjo. Rezultati meritev pridobljeni v okviru raziskave so bili statistično obdelani z analizo sipanja (ANOVA). Ključne besede: kirurška oblačila, termofiziološko udobje, tkanine, netkane tekstilije, toplotna upornost, toplotna prevodnost.
