“…UV‐DRS spectra of uncoated (line A), neat extract (curve B) and extract containing AuNPs coated cotton (curve C) are presented in Figure . Both the coated and uncoated cotton fabrics were studied for UV penetration efficiency by calculating the ultraviolet protection factor value (UPF) and observed over the wavelength ranging from 280 to 400 nm . The calculated UPF value of AuNPs coated cotton fabric was found to be 16, which is categorized as good protection efficiency according to the standard.…”

[67,68] The calculated UPF value of AuNPs F I G U R E 6 HR-TEM with SAED images of AuNPs obtained from 0.001 M (A and B), 0.01 M (C and D) of chloroauric acid coated cotton fabric was found to be 16, which is categorized as good protection efficiency according to the standard. The computed UPF values are 3.96 and 8.94 for uncoated-and extract-coated cotton, respectively.…”

Our study reports greener synthesis of gold nanoparticles (AuNPs) tethered to the extract of Croton sparsiflorus and in vitro evaluation of UV‐protection, antibacterial and anticancer activities. Sophisticated instrumental analytical techniques such as UV–vis spectrophotometer, FT‐IR, XRD, FE‐SEM, and TEM were employed for the existence and confirmation of the nanoparticles. FT‐IR and HPLC analysis were executed in the identification of the plausible functional groups implicated in the reduction of gold ions to AuNPs. UV protection property and antibacterial action of AuNPs‐coated cotton fabric were also presented. Moreover, in vitro anticancer evaluation against HepG2 cell line was conducted by MTT assay for Croton sparsiflorus extract derived AuNPs in different concentrations (50 to 150 μg/ml). Thus, the results of this work revealed that greener synthesized AuNPs exhibited good therapeutic applications as UV‐protection, antibacterial and anticancer agents.

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.

“…Some types of sol-gel systems also have bacteriostatic or antibacterial effects [16][17][18][19][20][21][22]. These systems are anatase-modified photoactive TiO2 coatings and sol-gel coatings with colloidal metals or metal compounds embedded in them, such as silver, silver salt, copper compound, zinc or quaternary ammonium salt [18], so sol-gel technology can be applied to textiles to develop various functional finishes with antibacterial [23][24][25][26][27][28][29][30][31][32], water repellent [33][34][35][36][37][38], superhydrophobic [39][40][41][42][43][44], oil/water separations [45][46][47][48][49][50][51][52][53], flame-retardant [54][55][56][57][58][59][60][61]…”

The commercial availability of inorganic/organic precursors for sol-gel formulations is very high and increases day by day. In textile applications, the precursor-synthesized sol-gels along with functional chemicals can be deposited onto textile fabrics in one step by rolling, padding, dip-coating, spraying or spin coating. By using this technology, it is possible to provide fabrics with functional/multi-functional characteristics including flame retardant, anti-mosquito, water- repellent, oil-repellent, anti-bacterial, anti-wrinkle, ultraviolet (UV) protection and self-cleaning properties. These surface properties are discussed, describing the history, basic chemistry, factors affecting the sol-gel synthesis, progress in sol-gel technology along with various parameters controlling sol-gel technology. Additionally, this review deals with the recent progress of sol-gel technology in textiles in addressing fabric finishing, water repellent textiles, oil/water separation, flame retardant, UV protection and self-cleaning, self-sterilizing, wrinkle resistance, heat storage, photochromic and thermochromic color changes and the improvement of the durability and wear resistance properties.
