The popular use of silver nanoparticles (Ag NPs) in commercial textile products that inhibit odor- and/or infection-causing bacteria has continuously raised concerns about their washing durability. The poor durability not only deteriorates the antibacterial performance, but also results in unwanted leaching of NPs into washing solutions. In this study, we showed how the incorporation location of Ag NPs—interior vs. exterior of cotton fiber—governs their durability against consecutive simulated home launderings. The superior washing durability of interior NPs was confirmed. The Ag losses after 50 laundering cycles for interior and exterior systems were 16% and 63% in water and 24% and 78% in detergent solution, respectively. The cotton fabric containing interior NPs predominantly released ionic Ag, whereas the fabric containing exterior NPs released particulate Ag.

Surface Dielectric Barrier Discharge

Cotton-fabric-supported silver nanoparticles (Ag NPs) have aroused great attention due to their remarkable physical and chemical properties and excellent broad-spectrum antibacterial performance.In this work, a surface dielectric barrier discharge (DBD) plasma method is developed and employed to prepare cotton fabric supported Ag NPs (Ag/cotton) for the first time. UV-Vis and X-ray photoelectron spectroscopy (XPS) results confirm the formation of Ag NPs. TEM images show that the size of Ag NPs is in the range 4.8–5.3 nm. Heat-sensitive cotton fabrics are not destroyed by surface DBD plasma according to FTIR and XRDresults. Wash fastness of the Ag/cotton samples is investigated using ultrasonic treatment for 30 min and it is shown that the Ag NPs possess good adhesion to the cotton fabric according to UV-Vis spectra. Antibacterial activity of the Ag/cotton samples shows that obvious bacteriostasis loops are observed around the samples with the appearance of both Gram-negative bacterium Escherichia coli (E. coli) and Gram-positive bacterium Bacillus subtilis (B. subtilis). The average diameter of the bacteriostasis loops against both E. coli and B. subtilis becomes larger with an increasing silver loading amount.This work provides a universal, fast, simple, and environmentally-friendly cold plasma method for synthesizing Ag NPs on heat-sensitive materials at atmospheric pressure.

A new and straightforward route was proposed to incorporate silver nanoparticles (Ag NPs) into the surface of polyurethane nanofibers (PU NFs). Uniform distribution of in situ formed Ag NPs on the surface of PU NFs was achieved by adding AgNO3 and tannic acid in a PU solution prior to the electrospinning process. The synthesized nanofiber mats were characterized with state-of-the-art techniques and antibacterial performances were tested against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacteria. The cytocompatibility and cell behavior were studied by using fibroblast cells. Following this preparation route, Ag/PU NFs can be obtained with excellent antibacterial performance, thus making them appropriate for various applications such as water filtration, wound dressings, etc.

Silver nanoparticles which are highly effective in killing bacteria have been applied in many fields. One of its practical applications is that the silver nanopartcles are applied in textiles for creating antibacterial fabric. In this work, the cotton fabrics were immersed in nano silver colloid (diameter = 7-11 nm) which is prepared by polyol process with microwave heating. The antibacterial performance of the antibacterial cotton fabric was tested for different concentration of nano silver colloid, contact time germs, and washing time. It was found that antibacterial activity increased with the increasing concentration of nano silver colloid, contact time germs and with the decreasing washing time.

The Impact

Abstract The influence of Ketoconazole and β-CD/Ketoconazole was previously reported on cotton fabric as fungal skincare; however, the impact of nanosilver on the antifungal and antibacterial properties of the same products is unknown. Here, silver NPs were synthesized on β-CD/KZ composites and then attached to the cotton using a cross-linking agent. The nanocomposites and treated fabrics were analyzed by UV-vis, dynamic light scattering (DLS), zeta-potential and FE-SEM. The drug delivery and cytotoxicity of the products were also studied. The nanocomposites antimicrobial efficiency was examined on Candida albicans and Aspergillus niger as fungi and E. coli & S. aureus as bacteria. The synthesis of Ag-NPs on the β-CD/KZ amplifies both antifungal and antibacterial efficiencies. This also extends the drug regular release time for medical and drug delivery purposes. Having tremendous antimicrobial activities without cytotoxicity effects and regular release time of drug with excellent washing durability of treated samples make it suitable for medical applications likewise wound dressings and sportswear designed for sensitive skin.

Iron Coordination

In order to endow cotton fabric with the full wave band (290–410 nm) ultraviolet (UV) protection property, ionic liquid iron coordination complex (ILICC) was applied to modify cotton fabric. ILICC was prepared by in situ reaction on the surface of the cotton fiber directly. The Fourier transform infrared spectra, thermogravimetric and differential scanning calorimetry curves indicated that the strong interaction between ILICC and cellulose macromolecules of cotton fiber occurred through the O-Fe bond. Scanning electron microscopy images and particle size analysis indicated that the surface of the modified cotton fiber was covered by the agminate ILICC particles with diameters of 700–1600 nm. Investigation on the UV protection performances indicated that the UV transmittances ( T%) of the modified cotton fabric were less than 1.3% for the full wave band (UVA and UVB) UV. The washing durability results showed that the UV protection factor values were more than 95 when the modified cotton fabric was washed with 30 st washing cycles. The reason for the excellent UV protection performance of the modified cotton fabric was absorption and shielding of ILICC particles to UV light.

The Cross

To explore the combination of silver nanoparticles (Ag NPs) prepared in a green manner with cotton fabrics and the washing durability of the fabric after the combination. In this paper, the natural material, honeysuckle extract, was used as a reducing agent to prepare the Ag NPs’ solution. The structure and size of Ag NPs were analyzed using ultraviolet–visible spectrophotometry (UV–vis), transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray powder diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy characterization. The results showed that Ag+ was successfully reduced to Ag0 by the honeysuckle extract, the particle size was about 10.59 nm, and the potential was −42.9 mV, so it had strong electrostatic repulsion and good stability. Meanwhile, it was found that the synthesized Ag NPs were well coated by the honeysuckle extract, so they would not aggregate. Then, the cotton fabric was finished with Ag NPs’ solution by the dipping method using a complex of polymaleic acid (PMA) and citric acid (CA) as a cross-linking agent to fix Ag NPs on the cotton fabric. The structures of cotton fabrics before and after finishing were characterized using FT-IR, scanning electron microscopy (SEM), XRD, X-ray photoelectron spectroscopy (XPS), and thermogravimetric (TG) analysis, and the multifunctional properties of the finished cotton fabrics were explored by measuring the antibacterial rate, the wrinkle recovery angle (WRA), and the UV protection factor (UPF) value. The results show that Ag NPs were successfully loaded onto cotton fabric, and the PMA + CA compound was successfully cross-linked to the fabric. The cross-linked Ag NPs’ cotton fiber was rougher than that before cross-linking, and its TG stability improved. The PMA + CA compound fixed Ag NPs on the cotton fabric through chemical bonds, so it still had a 99% antibacterial effect against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) after 50 washings. Compared with unfinished cotton fabric, the UPF value and WRA of the cross-linked Ag NPs cotton increased by 34.09 and 98°, respectively, and its color did not change much.
