In this present research, a superhydrophobic cotton fabric exhibiting a water contact angle of 155.2° has been prepared via dip‐coating technique involving silica nanoparticle deposition followed by silane hydrophobization. Interestingly, the mirror‐like phenomenon was also observed at the interface between was and modified cotton fabric. The surface morphology and microstructure of the modified fabrics were characterized by scanning electron microscope (SEM) and energy dispersive x‐ray spectroscopy (EDX). Fourier transform infrared spectroscopy (FTIR) was performed for functional group detection on a modified cotton surface. For practical applications, the washing durability was characterized by measuring contact angle values before and after washing cycles. Besides this, the durability of the superhydrophobic cotton fabric was measured under different harsh environmental conditions such as highly acidic, neutral, and highly basic environment. After each measurement, water contact angles and sliding angles were measured for dynamic stabilities. Again the modified coated cotton fabric showed strong resistance to the various organic solvents. Along with the above studies, the physical and mechanical durability of the coated fabric was also measured for both industrial and household importance.

“…By UV-Vis-NIR spectroscopy, as shown by Figure 2, an enhancement in the absorption intensity with the increase of the TiO2 load was observed. The uncoated cotton has a specific absorbance spectra that can be observed in Figure 2 ( Batool and Shah 2018;Jovic et al 2015;Moreira et al 2019;Zhang and Yang 2012). The UV-Vis-NIR spectra suggest that the TiO2 NPs were successfully impregnated in raw cotton, without the need to use a crosslinking agent.…”

Nanoparticles (NPs) of titanium dioxide (TiO2) are promising for the photocatalytic degradation of organic compounds, arising as an excellent alternative to conventional bleaching processes. Within this background, aqueous suspensions of TiO2 NPs were impregnated by the pad-dry method in raw cotton. The hydrophilic properties and whiteness index (WI) of Berger were the main parameters examined before and after the TiO2 treatment. In the absence of water, using a UV-Vis lamp, high hydrophilicity was found for raw cotton. Diversely, under UV-LED radiation, the presence of water molecules in the coated cotton was revealed to be a crucial parameter in enhancing its whiteness. A comparable WI of Berger with conventional bleaching methods was obtained using 0.5 g L-1 TiO2 suspension under UV-LED radiation, suggesting that the impregnation of TiO2 NPs can be a promising alternative for the industrial bleaching methods, as it proves to be more sustainable and with low operating costs.

The reaction of cyanoethyl cellulose with para-bromo diazonium chloride resulted in the creation of a novel bromo-containing cellulosic (MCPT). The dispersion stability of MCPT has been improved by its dispersion into 1% waterborne polyurethane acrylate (WPUA). TEM, particle size, and zeta potential were used to track the dispersion stability of aqueous MCPT and MCPT in 1% WPUA and particle size. The prepared MCPT has been utilized as a unique green colorant (dye) for the printing of cotton, polyester, and cotton/polyester blend fabrics using a silkscreen printing technique through a single printing step and one color system. Color improvement has been achieved by printing different fabrics with a printing paste of MCPT dispersed in 1% WPUA. The MCPT and MCPT in 1% WPUA printed fabrics were evaluated for rubbing, light, washing, and perspiration fastness, UV blocking activity, and antibacterial activity. These findings were established through structural optimization at the DFT/B3LYP/6-31 (G) level and simulations involving several proteins.
