Summary: The use of toxic reagents in the finishing process of superhydrophobic cotton fabrics restricts their application. A green and sustainable method for preparing superhydrophobic cotton fabrics is needed. In this study, phytic acid (PA) etching and subsequent coating with epoxidized soybean oil (ESO)-derived thermosets and stearic acid (STA) were used to create a superhydrophobic cotton fabric. The finished fabric exhibited excellent self-cleaning properties and retained its inherent properties.

Summary: A durable superamphiphobic cotton fabric was successfully obtained by coating SiO2 aerogel particles, polydimethylsiloxane, and perfluorooctyltriethoxysilane on a cotton fabric. The coated fabric exhibited porous rough surface structure and low surface energy, showing excellent self-cleaning and stain-resistance properties. The fabric also demonstrated good durability and maintained superamphiphobicity even after mechanical abrasion or UV irradiation.

Summary: The study investigated the effect of microwave irradiation time on the zinc oxide nanorod-coated cotton fabrics, revealing that the growth of the nanorods increased with irradiation time. The coated fabrics showed excellent photocatalytic activity and physiological comfort, with stains disappearing within 4 hours and fabrics turning almost white in 6 hours. The thermal properties, water vapor permeability, air permeability, and stiffness of the fabrics were also analyzed, showing improvements in some aspects while maintaining overall comfort.

Summary: Self-dispersive and reactive BiVO4 nanoparticles were prepared and applied on cotton fabric to enhance dispersion stability and provide excellent ultraviolet protection and self-cleaning properties. The modified BiVO4 with a mole ratio of ATAC and AGE at 3:2 showed the best dispersion stability, leading to cotton fabric with optimal ultraviolet protection and self-cleaning capabilities. A possible mechanism for the binding of BiVO4 with cotton fabrics was proposed.

Summary: Our research aimed to prepare semiconductive textile with multifunction activity such as hydrophobicity, antibacterial, and UV protection. Herein, propynyl benzo thiazolone (TH) and its polymer (PTH) were assynthesized and investigated by FT-IR analysis. Further, the cotton fabrics were grafted in situ with each poly (propynyl benzo thiazolone) and with the as-synthesized hydrogel based on gelatin/PTH (PTH-G-T). The PTH-T and PTH-G-T were investigated by (FT-IR), (SEM), UV protection (UPF), and contact angle, and further, their electrical properties were studied by impedance spectroscopy, and dc conductivity of PTH, PTH-T, and PTH-T-G obtained at low frequency exhibited good conductivity upto 10-4 S cm- 1, 4.5x10-8 and 1.7x10-7 S cm- 1, respectively. An equivalent circuit model was used to investigate the impedance spectra of PTH-T and PTH-G-T samples. The impedance could be split into two components. One component was identified as an inhomogeneity contribution, while the other was recognized as an intrinsic conduction component that exhibited characteristic semiconductor behavior. Various conduction experiments and theories are used to explain the results. Besides, they have good antibacterial and excellent UV protection. The outcomes assured the ability usage of the treated cotton fabrics in health monitoring apparel.
