CaCuTiO (CCTO) nanoparticles (NPs) were screen printed on pristine cotton fabric. The CCTO-coated fabric was characterized using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), Raman, X-ray diffraction (XRD), x-ray photoelectron spectrometer (XPS), and field emission-scanning electron microscopy (FE-SEM). The modified fabric photocatalytic antibacterial and dye-degradation abilities were assessed. After 2 h of bacterial contact, unwashed CCTO-embedded cotton reduced E. coli and S. aureus by 95.1% and 94.3%, respectively. After 20 washing cycles, the modified fabric was able to eliminate S. aureus and E. coli by more than 85%. The cloth coated with CCTO-NPs degraded the methylene blue (MB) dye by 82% in 4 h, as opposed to the pure cotton's 11% degradation rate. The embedding of CCTO-NPs onto the cotton surface had minimal effect on fabric intrinsic properties like tensile strength, abrasion resistance, and water-vapor permeability.

Unidirectional moisture-conducting fabrics were prepared by electrospraying polyvinylidene fluoride (PVDF) and polyvinyl chloride (PVC) onto three green fabric substrates, namely cotton, hemp, and modal. Experiments were conducted to examine the effects of coating thickness, coating material, and substrate material on the moisture conductivity of the fabrics. The electrospraying technique was effective in forming uniform and strongly adhered PVDF and PVC coatings on the fabric substrates, and the coating thickness and material type had a significant effect on the fabric's moisture conductivity.

Radiative cooling is an emerging zero-energy-consumption technology for human body cooling in outdoor scenarios during hot seasons. However, existing radiative cooling textiles are limited by low intrinsic cooling power, high hydrophobicity, and heat-insulating properties, which seriously impede a satisfying cooling effect, perspiration-wicking, and heat dissipation, thus limiting human thermal comfort in practical situations. Here, we developed a radiative cooling meta-fabric that was integrated with high perspiration-wicking and thermal conduction capacity.

Brown cotton and white cotton are two important raw materials used in the cotton fiber industry. Clarifying the differences in morphology, agronomic traits, and fiber pigments between these varieties can facilitate the implementation of corresponding cultivation and breeding techniques. Therefore, we obtained F generation brown cotton plants through hybridization and compared them with their parents.

Cationic polymers have been used in the cationization of cotton fabrics for salt-free dyeing, but commonly used polymers are limited by their high molecular weight and low adsorption efficiency, leading to high dosage or complex modification conditions. In this study, polyallylamine with low molecular weight was found to be an efficient cationic agent for cotton modification and the modified fabrics can be salt-free dyed with different kinds of reactive dyes after the optimization of the modification process. Furthermore, the modification bath was reused by replenishing a small amount of cationic agent and adjusting the pH to the original level.

Polyphenols, as one of the primary compounds produced by plant secondary metabolism, have garnered considerable attention because of their non-toxic, environmentally friendly, and biodegradable properties, as well as their notable medicinal value. This study presents a metabolomic analysis of polyphenols from 11 woody plants, including , , and , investigating a total of 40 polyphenolic metabolites. A differential metabolite dynamics map highlighted the five most differentiated substances among the 11 plants, including vitexin, dihydromyricetin, genistin, resveratrol, and isorhamnetin.
