“…The W adh for water increased to 145 mJ/m 2 for both fabrics. The adhesion properties of fabrics were higher, and for both fabrics the coating process with TiO 2 sol should be more effective (Lam et al 2011;Calvimontes et al 2011;Caschera et al 2014;Navaneetha Pandiyaraj and Selvarajan 2008). This is confirmed by the results of a wettability study with TiO 2 sol (Fig.…”

The method of TiO 2 -anatase film preparation on cotton and viscose fabric surfaces using the sol-gel process and microwave treatment is presented. Microwave treatment was used to change the amorphous TiO 2 form to anatase directly on the fabrics. The influence of microwave treatment conditions on the obtainable polymorphic form of TiO 2 was examined. Fabrics were pretreated with low-temperature air plasma (30 min). The root mean square height in the selected area increased from 44 to 166 nm (cotton) and from 9 to 112 nm (viscose). Infrared analysis showed the new band at 1748 and 1732 cm -1 corresponding to C=O stretching for plasma-treated cotton and viscose textiles, respectively. The plasma pretreatment also improved the wetting properties by TiO 2 sol and increased the surface free energy of fabrics. TiO 2 film thickness was 180 nm (12 %wg. Ti) and 140 nm (3 %wg. Ti) for cotton and viscose, respectively. TiO 2 -modified cotton reduced the nicotine concentration three times more and TiO 2 -modified viscose was two times higher under sunlight compared to raw fabrics. No changes in strength were observed for TiO 2 -modified cotton, while the strength of TiO 2 -modified viscose decreased about 45 %. No effect of UV irradiation on cotton and a slight reduction of the strength of raw viscose (7 %) and TiO 2 -modified viscose (16 %) were observed. The Ti contents after washing decreased from 12 to 11 % (cotton) and from 3 to 2.6 % (viscose). The presented method allows obtaining TiO 2 film-anatase on the cotton and viscose fabrics, but its total effectiveness is better for cotton fabrics.

“…5). Such nano-topography changes on the fabric surfaces are also described in the literature (Navaneetha Pandiyaraj and Selvarajan 2008;Shishoo 2007;Mihailovic et al 2011). The surface development can provide a new pathway for the TiO 2 sol and improve its application.…”

“…The mean pore radius on the fabric surface was calculated using Lucas Washburn equation [23].The modified equation is stated as, ………….. (1) where H -wicking height, r -Pore radius, η -Coefficient of viscosity of the liquid, γ -Surface tension of the liquid, tTime taken for wicking. The slope of the plot between H 2 and t gives the mean pore radius of fabrics.…”

Oxygen plasma treatment and/or cellulase enzyme treatment was carried to improve the surface properties of cotton fabrics for medical applications. The influence of Plasma (P), enzyme (E), plasma preceded by enzyme (EP) and enzyme preceded by plasma (PE) treatments on hydrophilicity of the cotton fabrics was studied using standard wicking test. The physical and chemical modification due to plasma and enzymatic treatments were analyzed using SEM and ATR-FTIR spectroscopy. The FTIR results revealed that the oxygen plasma has modified the surface chemically by introducing oxygen containing groups (C=O, C-O, COO -) onto the fabric surface and enzyme have hydrolyzed the cellulose molecule. The physical etching of the fabric surface was observed in SEM photographs and weight loss measurements. The modified fabrics were given antimicrobial finish and tested for its antimicrobial activity against S.aureus and E.coli using AATCC 100 test. The EP treated fabric was found to have 100% bacterial reduction. The wash durability of the finished fabrics was also assessed and the results are discussed.

“…In this case, the top of the substrate is covered by plasma polymer. On the other hand, inert gases, such as, Argon (Ar), Neon (Ne) and Helium (He) never form polymers in a plasma state [14]. However, these plasmas can cause some chemical and physical reactions on the surface of substrates because of highly energetic species such as free radicals, ions, photons and ultraviolet (UV) radiations.…”
