“…The recombination of the species may then favor the formation of polar groups in the substrate, which contributes to the increase in surface energy of the material and consequently to its hydrophilic character 46,47 . In samples submitted for this process, the contact angle measurement cannot be performed since the droplets of both liquids (water and diiodomethane) deposited on the surface were immediately absorbed.…”

Cellulose is a polymer widely available in nature, however its applications may be restrict due to its hydrophilic character. The creation of hierarchical structures on the surface is one of the required factors to obtain the hydrophobicity of this material. In order to compare the morphological and chemical effects caused by the action of different gases in the creation of nanostructures on the cellulose surface, samples were exposed to oxygen (O 2 ) and sulfur hexafluoride (SF 6 ) plasma treatments. The changes in morphology after treatment prove that both the gases were able to create similar nanostructures in the material. The analysis of elemental composition and identification of functional groups on the sample surface showed that chemical modifications occurred differently for each treatment. Contact angle measurements revealed that samples treated by O 2 plasma remained hydrophilic, whereas low receptivity to polar (θ > 120º) and non-polar (θ > 100º) liquids was observed for samples exposed to SF 6 plasma.

“…e fabrication of coatings on naturally micro-roughened textile bre surfaces produces speci c surface nano-modi cations, which signi cantly contribute to water-and oil-repellent properties. Accordingly, an increase in the bre surface roughness by plasma surface etching [49][50][51][52][53][54][55][56][57], prior the formation of the repellent sol-gel coating, enables the creation of a dual micro-to nano-structured bre topography with low adhesion super hydrophobicity, very high oleophobicity and self-cleaning properties. Such surfaces are characterised by a water static contact angle that is higher than 150°, an n-hexadecane static contact angle that is higher than 140° and a water roll-o angle that is lower than 7°, which allows water droplets to roll o fabric surfaces very easily, thus removing solid particles of dirt from the bres.…”

“…Te so karakterizirane s statičnimi stičnimi koti vode, večjimi od 150°, in koti zdrsa kaplje vode, manjšimi od 10° [4,5,[7][8][9]. Pomembna dejavnika, ki omogočata doseganje superhidrofobnih in samočistilnih lastnosti tekstilij, sta kemijska sestava in morfologija površine tekstilije [10,11]. Vodo-in oljeodbojne zaščitne lastnosti ob hkratnem ohranjanju dihalne aktivnosti tekstilije lahko dosežemo z uporabo ustreznega postopka kemijske apreture, kjer se je v zadnjem desetletju uveljavila tehnologija sol-gel.…”

IzvlečekV raziskavi je bil proučevan vpliv barvanja s tremi reaktivnimi barvili Avitera SE (rumeno, rdeče in modro) na funkcionalne lastnosti bombažnih tkanin, apretiranih z nanodelci SiO 2 , vodo-in oljeodbojno apreturo (FAS) ter kombinacijo obeh (SiO 2 + FAS). Hkrati je bil proučevan tudi vpliv nanesenih apretur na spremembo barve barvanih vzorcev. Prisotnost različnih apretur smo proučevali z vrstično elektronsko mikroskopijo (SEM) in infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR). Vodo-in oljeodbojnost nebarvanih in barvanih apretiranih vzorcev pred pranjem in po njem smo določili z meritvami statičnih stičnih kotov vode in n-heksadekana, kotov zdrsa vode in z ocenami oljeodbojnosti (AATCC 118-1966 T). Barvne lastnosti vzorcev so bile proučevane pred nanosom apretur in po njem, po pranju in dvainsedemdeseturnem osvetljevanju. Prisotnost apreture je bila potrjena tako z rezultati FTIR kot SEM-analize. Superhidrofobne lastnosti so bile dosežene na vseh apretiranih vzorcih in se zaradi predhodnega barvanja niso poslabšale. Kljub nanosu nanodelcev SiO 2 vzorci niso izkazali samočistilnih lastnosti. Nanos vseh apretur je zagotovil oljeodbojnost vzorcev, ki se je na predhodno barvanih vzorcih celo rahlo povečala. Apreture so bile dobro pralno obstojne. Prisotnost apretur je močno vplivala na barvo vzorcev, ne glede na to, ali so bili barvani ali ne. Apretura FAS je povzročila potemnitev in porumenitev vzorcev, medtem ko je apretura SiO 2 vplivala na spremembo barve na modro, rumeno oziroma rdečo. Iz rezultatov barvnih sprememb smo opazili, da so imeli apretirani barvani vzorci zelo slabo barvno obstojnost na osvetljevanje. Ključne besede: reaktivna barvila, nanodelci SiO 2 , FAS, sol-gel, lotusov efekt, oljeodbojnost Abstract In the research, the influence of dyeing with three reactive dyes Avitera SE, i.e. yellow, red and blue, on the functional properties of cotton fabrics finished with SiO 2 nanoparticles, hydro-and oleophobic finish (FAS) and the combination of both (SiO 2 + FAS) was studied. At the same time, the influence of applied finishes on the colour change of dyed cotton fabrics was studied as well. The presence of different finishes on cotton was studied using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR
