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.

Abstract. In this research pure cotton textile was successfully modified by zinc oxide nanosol prepared by the sol-gel method. The cotton fabric was dipped in the nanosol solution for 10 minutes, dried at 90 ºC for 10 minutes with further thermal post-treatment at 120 ºC, 140 ºC or 160 ºC for 2 minutes. Comparison of coating of samples prepared using different thermal posttreatments was made. Before and after laundering tests ultraviolet protective properties of the textile samples were determined according to the standards, results show that textiles after treatment with nanosol have excellent ultraviolet protection properties, as well treated samples after laundering tests (50 washing-drying cycles) still provide excellent ultraviolet protection. Analyses based on the scanning electron microscopy and spectrophotometer measurements show that obtained textile coatings are distributed evenly, not only on the surface of yarns but in the depth of textile material as well, and are resistant to exploitation process that indicates about very good adhesion between the coating and the fabric surface.

“…TiO 2 nanoparticles are presumed to be bound with cotton through ester bonding over the non-homogeneous irregular structure of the cotton making it more self-cleaning, ultraviolet irradiation resistant and antibacterial in nature [4][5][6]. Similar properties were achieved for polyester nonwoven structures coated with titananium dioxide nanoparticles by reactive sputtering methods [7].…”

Herein, the hydrophobic and self-cleaning properties of three different fabric surfaces have been evaluated after applying titanium dioxide (TiO 2 ) nanofinishes. The nanoparticles were prepared by sol-gel techniques and were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and dynamic light scattering (DLS) methods. The ultra-refined particles were applied over three different fabric substrates having similar weave of Z-twill (3/1). The yarns of 100% polyester, blend of viscose with mod-acrylic and high performance polyethylene containing 16 yarn count (Ne) and 31.496 and 15.748 ends/cm and picks/cm, respectively, were used for required fabric preparation. The different fabric structures were applied with self-cleaning finish of TiO 2 nanoparticles prepared in our laboratory and the results were compared with commercially available finish Rucoguard AFR. The static contact angles, UV-protection factor, air permeability and hydrophobic activity of nanofinished fabric helped in evaluating their breathability and self-cleaning properties.
