“…Another use of these materials is in sports clothes for long-lasting freshness. Chitosan [ 7 , 8 , 9 , 10 ], ammonium salts [ 11 , 12 , 13 , 14 ], triclosan [ 15 , 16 ], and metal oxide nanoparticles [ 17 , 18 , 19 , 20 , 21 ] are the examples of most common materials used for functional textile products. These agents can also be classified into organic and inorganic compounds.…”

In this study, zinc oxide nanoparticles (nZnO) were synthesized, deposited, and successfully used for surface modification of cotton to enhance antimicrobial properties. An in situ ultrasonic acoustic method was applied to anchor nZnO on cotton. The results of scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction confirmed the presence of nZnO on cotton. A homogenous distribution of nZnO with an average particle size 27.4 nm was found during the analysis of results. Antimicrobial performance of cotton-nZnO (C-nZnO) composites was evaluated against Gram-negative and Gram-positive microbes. The deposited amount of nZnO on C-nZnO composites was determined by volumetric titration through inductive couple plasma atomic emission spectroscopy. C-nZnO composites showed excellent antimicrobial performance especially against both Staphylococcus aureus (Gram-positive) and Escherichia coli. The durability and stability of C-nZnO composites were tested against leaching and washing. No significant fluctuation was found on deposited amount of nZnO before and after washing test for optimized sample. The results demonstrate that synthesized C-nZnO composite samples can be used as an alternative for antimicrobial bandages.

“…Medical textiles, in particular, highlight the need for an antibacterial finishing [ 3 , 4 , 5 ], as pathogens present on personal protective equipment (PPE), gowns, privacy curtains, or bedding can be easily transferred between the hospital environment, patients and healthcare workers, either directly or indirectly [ 6 ]. A number of antimicrobial agents have been incorporated into textiles for infection control, including antibiotics [ 7 , 8 ], quaternary ammonium salts [ 9 , 10 ], silver nanoparticles [ 11 , 12 ], graphene [ 13 , 14 ] and dendrimers [ 15 , 16 ]. However, these all exhibit certain limitations, such as being expensive and/or difficult to dye or finish on textiles, can lead to drug-resistant strains [ 17 ], are potentially toxic or lead to undesired side effects (rashes or allergic responses) on the wearer [ 1 ], or possess a limited range of antibacterial function (i.e., against a single class of pathogen) [ 18 ].…”

Towards the goal of developing scalable, economical and effective antimicrobial textiles to reduce infection transmission, here we prepared color-variable photodynamic materials comprised of photosensitizer (PS)-loaded wool/acrylic (W/A) blends. Wool fibers in the W/A blended fabrics were loaded with the photosensitizer rose bengal (RB), and the acrylic fibers were dyed with a variety of traditional cationic dyes (cationic yellow, cationic blue and cationic red) to broaden their color range. Investigations on the colorimetric and photodynamic properties of a series of these materials were implemented through CIELab evaluation, as well as photooxidation and antibacterial studies. Generally, the photodynamic efficacy of these dual-dyed fabrics was impacted by both the choice, and how much of the traditional cationic dye was employed in the dyeing of the W/A fabrics. When compared with the PS-only singly-dyed material, RB-W/A, that showed a 99.97% (3.5 log units; p = 0.02) reduction of Staphylococcus aureus under visible light illumination (λ ≥ 420 nm, 60 min), the addition of cationic dyes led to a slight decrease in the photoinactivation ability of the dual-dyed fabrics, but was still able to achieve a 99.3% inactivation of S. aureus. Overall, our findings demonstrate the feasibility and potential applications of low cost and color variable RB-loaded W/A blended fabrics as effective self-disinfecting textiles against pathogen transmission.

“…To further visualize the antibacterial process of the Cl-BPDMH finished PET-3 fabrics, E. coli was stained using the live/dead BacLight Bacterial Viability Kit [ 47 , 48 ]. Afterward, the dynamic process of stained E.coli contacting with PET-3 fabrics compared with raw PET fabrics was observed by rotating confocal fluorescence microscope (Olympus IX explore SpinSR10 instrument).…”

Pathogenic bacteria can proliferate rapidly on porous fabrics to form bacterial plaques/biofilms, resulting in potential sources of cross-transmissions of diseases and increasing cross-infection in public environments. Many works on antibacterial modification of cotton fabrics have been reported, while very few works were reported to endow poly(ethylene terephthalate) (PET) fabrics with non-leaching antibacterial function without compromising their innate physicochemical properties though PET is the most widely used fabric. Therefore, it is urgent to impart the PET fabrics with non-leaching antibacterial activity. Herein, a novel N- halamine compound, 1-chloro-3-benzophenone-5,5-dimethylhydantoin (Cl-BPDMH), was developed to be covalently bonded onto PET fabrics, rendering non-leaching antibacterial activity while negligible cytotoxicity based on contact-killing principle. Bacterial was easily adhered to Cl-BPDMH finished PET fabrics, and then it was inactivated quickly within 10 s. Furthermore, the breaking strength, breaking elongation, tearing strength, water vapor permeability, air permeability and whiteness of Cl-BPDMH finished PET fabrics were improved obviously compared to raw PET fabrics. Hence, this work developed a facile approach to fabricate multifunctional synthetic textiles to render outstanding and rapid bactericidal activity without compromising their physicochemical properties and biocompatibility.
