Carboxymethyl chitosan (CMCTS) and silver nanoparticles (Ag NPs) were successfully linked onto a cotton fabric surface through a simple mist modification process. The CMCTS binder was covalently linked to the cotton fabric via esterification and the Ag NPs were tightly adhered to the fiber surface by coordination bonds with the amine groups of CMCTS. As a result, the coating of Ag NPs on the cotton fabric showed excellent antibacterial properties and laundering durability. After 50 consecutive laundering cycles, the bacterial reduction rates (BR) against both S. aureus and E. coli remained over 95%. It has potential applications in a wide variety of fields such as sportswear, socks, and medical textile.

Cotton textiles with persistent antibacterial qualities are crucial in halting the spread of bacteria and other infections. However, fugitive bacteria and drug-resistant pathogens have rendered tremendous challenges in the development of cotton fabrics with long-lasting antibacterial efficacy. The work aimed to innovatively propose a functional cotton fabric integrating intelligent bacteria-capturing and dual antibacterial properties for efficacious personal health management.

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.

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.
