“…Very recent studies have discussed the application of nanosized TiO 2 in textile finishing, using the sol-gel technique, to impart effective protection against UV radiation and bacteria, stain resistance, deodorization, as well as self-cleaning because of its photocatalytic activity [6][7][8][9][10][11][12][13][14][15].…”

In this study, the effect of UV irradiation on mechanical properties of both natural and synthetic fabrics is investigated. Also the UV degradation of fabrics before and after TiO2 padding is studied. Cotton is used as natural fabric, and polyester, polypropylene, and polyamide were used as synthetic fabrics. After deposition with TiO2, prepared samples were irradiated by different dosage of UV light and the changes in fiber surface and the adhesion of nanoparticles is tested. The scanning electron microscopy, elemental analyses of Ti, and other methods were used. In some cases, the effect of stabilization of nanoparticles on fibers by UV light was realized. Reasons of this stabilization are the surface changes of polymer fibers-increase in surface roughness and oxidation of surface.

“…Nano-titanium dioxide (nano-TiO 2 ) is used as a common catalyst for its optical and electrical properties, high photocatalytic activity, chemical stability, non-toxicity, good availability, and no corrosion due to light (Xu et al 2008, Saha et al 2011. It can create anti-bacterial coating due to UV absorption and its photocatalytic properties, and prevent the penetration of UV radiations (Daoud et al 2005, Wong et al 2006.…”

When chemically treating wood products is used to enhance the properties, the distribution of chemicals in the wood can be more important than the amount of chemical uptake. In this research, two moisture contents (MC) (0 and 25%) were used to study the effect of MC on the nanomaterial retention and distribution in cottonwood (Populus deltoides) sapwood treated with nano-titanium dioxide. The wood samples were impregnated by a full-cell process at three levels of nano-TiO 2 concentration: 0,5; 1 and 1,5%. The nanomaterial retention was calculated and SEM images were used to investigate the distribution of nanoparticles in the wood. The results showed that increasing the nano-TiO 2 concentration caused more retention and the MC difference caused almost identical retention at 0,5 and 1% concentrations. Although the retention in the 0% MC samples was slightly more than those of 25% MC, this retention was significantly more in these samples (0% MC) at 1,5% concentration. SEM images indicated that the nanoparticles had more uniform distribution in the 0% MC samples than the 25% MC ones and the difference was clearly visible at 1,5% concentration. Low MC ranges (about 0%) are better than high MC's to impregnate cottonwood samples with nano-TiO 2 by using the full-cell process.

“…Their results showed biocidal additives Octenidine and CTAB exhibit high inhibition rate of more than 90% against the fungi Aspergillus niger after 4hr of leaching, whereas colloidal Ag treated samples without sol-gel have the lowest inhibition. Daoud et al (2005) coated the cellulosic fibers with titanium oxide nanoparticles, which were obtained from aqueous titania sol. Titanium isopropoxide was hydrolysed and condensed in water to obtain the titania sol coating at low temperature.…”

“…Titanium isopropoxide was hydrolysed and condensed in water to obtain the titania sol coating at low temperature. The stability of titania coating and the antibacterial activity of the coating was analyzed [51]. Treatment with sodium carbonates solutions showed less leaching behavior, which indicated that titania sols were strongly bonded with the cellulosic substrate.…”
