“…2 It is found that the photocatalytic activities of TiO 2 are greatly dependent upon crystallinity, crystallite size, morphology, phase, and the porosity of the coating of TiO 2 particles. [3][4][5] and such unique photocatalytic properties of TiO 2 particles, especially nanocrystalline TiO 2 particles, enable TiO 2 nanoparticles to have been widely used to enhance the properties of fibre, yarns, and fabrics in the textile industry. 6 Nanocrystalline TiO 2 can effectively reduce the rate of photoyellowing by inhibiting free radical generation in TiO 2 -doped wool mixtures, which acts primarily as a UV absorber on wool in dry conditions and not as a photocatalyst.…”

ABSTRACT:Wool fibres are treated with titanate tetrabutyl in the presence of C. I. Reactive Blue 69 dye in one-pot process under hydrothermal conditions. The structural changes of wool fibres before and after treatments as well as the remaining particles are characterized by small-spot Micro X-ray fluorescence (µ-XRF), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC) techniques. The properties of percentage of exhaustion, K/S value, colour fastness to light, tension, photocatalytic activity, and diffuse reflectance spectrum (DRS) are also investigated. The experimental results indicate that after treatment with titanate tetrabutyl and C. I. Reactive Blue 69, wool fibres are evenly immobilized with a thin layer of anatase phase TiO 2 nanoparticles with an average grain size of less than 10 nm. The TiO 2 nanocrystals are synthesized and simultaneously grafted onto wool fibres via the C-Ti 4+ , S-Ti 4+ (Ti 2+ ), and N-Ti 4+ bonds. The thermal stability of wool fibres changes a little. The capability of wool fibres to protect against ultraviolet radiation is improved. The tensile properties decrease to some degree. The photocatalytic activity to decolourize methylene blue dye is endowed. A high degree of percentage of exhaustion and K/S value are obtained by adding a certain amount of acetic acid in the precursor solution, which can well be matched with the custom dip dyeing technique.

“…The formation of anatase phase at low temperature on textile material coated with titania nanosols is a big challenge because textile materials cannot endure high temperature [39]. Researchers are investigating some solutions such as steaming process [40,41], hydrothermal process [42], or solvothermal process [43] to produce anatase crystals at low temperature so far.…”

“…In addition, organic components such as microorganisms in textile surfaces and dyestuff residues in textile wastewater can also be decomposed by photocatalytic effect. By this way, photocatalytic effect ensures not only UV protection and self-cleaning but also antibacterial effect and ecological and economical wastewater treatment [43,44]. Figure 8 illustrates the self-cleaning properties of cotton fabric treated with titania nanosols.…”

In the chapter, sol-gel applications in textile finishing process such as flame retardancy, water, oil repellency, ultraviolet (UV) protection, self-cleaning, and antibacterial and antiwrinkle processes are reviewed. Sol-gel technology is well known in materials, metallurgy, ceramic, and glass industry since 1960 and has been researched in textile industry in the last decade. Sol-gel technology has some advantages when compared to conventional textile finishing process. Sol-gel technology, which is a method applied to the inorganic metal alkoxide or metal salts to organic textile materials, could impart the high, durable activity and multifunctional properties to different textile materials in the same bath at one step using low concentration of precursors. In addition, sol-gel technology presents alternatively economical, ecological, and environmental friendly process due to one-step application, using low concentration of chemicals, nonhalogenated chemicals, and nonformaldehyde release when compared to conventional processes.

“…Demands and necessity for bifunctional or multifunctional textiles is increasing. The textiles that can provide more than one innovative characteristic broaden the practical areas of final product (Dastjerdi et al 2010;Gorjanc et al 2013;Onar et al 2011). Simultaneous UV and antibacterial properties of textiles have been investigated by using different approaches, i.e.…”

The cellulose fabrics made from 100 % cotton with antibacterial and UV protective properties were successfully created by loading of Ag/TiO 2 nanocomposite during and after dyeing with yellow, red and blue reactive dye. Blank dyeing (dyeing with all chemicals except dye) was performed to show that reactive dyes have an ability to increase the adsorption and adhesion of Ag/TiO 2 nanocomposite on cotton fabrics. The colour of the samples before and after washing and exposure to artificial light was measured by reflectance spectroscopy. The presence of nanocomposite on samples was confirmed by scanning electron microscope. The increased adsorption capacity of cotton towards Ag/TiO 2 nanocomposite due to the presence of reactive dyes was confirmed by measuring the quantity of silver using inductively coupled plasma mass spectroscopy. The same samples showed excellent UV protective properties with UV protection factor (UPF 50?), and excellent antibacterial properties against E. coli and S. aureus. Due to a good adhesion of nanocomposite on samples where loading of nanocomposite and dyeing with reactive dye was performed simultaneously, the samples retained their excellent protective properties after repetitive washing cycles.
