20.500.12556/RUL-125435 Uporabne lastnosti desno-desnih pletiv Useful properties of right-right knitted fabrics Namen diplomskega dela je raziskati udobnostne in ognjevarne lastnosti štirih različnih materialov (bombaža, tencela, mikromodala in mešanice poliakrilata, tencela in tairylana) v treh različnih desno-desnih vezavah. Naredili smo primerjavo med pletivi iz konvencionalnih materialov in pletivi iz mešanice poliakrilata, tencela in tariylana, ki je negorljiv material in ga lahko uporabimo za izdelavo spodnjega perila za gasilce. Primerjali smo njihove prepustnostne lastnosti (zračno prepustnost, toplotno prevodnost, prepustnost vodne pare), omočljivost ter gorljivost, ki vplivajo tudi na udobnost oblačil pri nošenju. Pri izbiri spodnjega perila za gasilce je pomembno, da so pletiva odporna proti ognju, da imajo dobre absorpcijske lastnosti, kar omogoča izhlapevanje odvečne vlage in znoja, ter da so toplotno dobro prevodna, kar vpliva na toplotno udobje. Ugotovili smo, da ima mešanica poliakrilata, tencela in tairylana, ki je ognjevaren material, majhno zračno prepustnost, najmanjšo toplotno prevodnost in majhno prepustnost vodne pare ter za omočenje potrebuje največ časa v primerjavi z ostalimi preskušanimi materiali, tencelom in mikromodalom. Lastnosti pletiv so odvisne tudi od uporabljene vezave. Pletiva z gostejšo strukturo imajo manjše prepustnostne lastnosti kot pletiva, ki imajo redkejšo strukturo. The purpose of this diploma thesis is to explore the comfort and flame-retardant properties of knitted fabrics made from four different materials (cotton, tencel, micromodal, and a blend of polyacrylate, tencel and tairylan) in three different types of double jersey. Knitted fabrics made from conventional materials and knitted fabrics made from a blend of polyacrylate, tencel and tairylan were compared. The blend is a flame-retardant material and could be used to make underwear for firefighters. I compared its permeability properties (air permeability, thermal conductivity, water vapor permeability), wetting and flammability, which also influence the comfort of the clothing. When choosing underwear for firefighters, it is important that the knitted fabric is flame-retardant, has good absorption properties that allow excess moisture and sweat to evaporate, and good thermal conductivity properties that influence thermal comfort. It has been found that the blend of polyacrylate, tencel and tairylan, which is a flame-retardant material, has low air permeability, the lowest thermal conductivity and low water permeability and that, compared to the other materials used in the experiment – tencel and micromodal – it takes longer to wet. The properties of the knitted fabrics also depend on the weave used. Knitted fabrics with a denser structure have lower permeability properties than knitted fabrics with a looser structure.
