“…The antimicrobial HPL-CFs were prepared by bonding HPLs onto the surface of the CF activated and pretreated with the silane coupling agent CPTMS through a dipping−padding−drying process. 40 The feasibility of this coupling strategy was verified by pretreating CF with 10 wt % CPTMS in ethanol and then finishing with 2 wt % HPL. Figure 1a shows the Fourier transform infrared (FTIR) spectra of the CF, CPTMS-pretreated CF (CPTMS-CF), HPL-CF, and HPL.…”

The choice of the antimicrobial agent and finishing process is very important for the activity, durability, and safety of antimicrobial fabrics. Here, a novel antimicrobial cotton fabric (HPL-CF) was constructed by covalently bonding an antimicrobial agent, hyperbranched polylysine (HPL), onto the surface of a cotton fabric (CF) pretreated with a silane coupling agent, 3-chloropropyltrimethoxysilane (CPTMS). The multiple amino groups contained in the periphery of HPL make it possible to react with the CF to form multiple bonds, which is beneficial to improve the durability and safety of HPL-CFs. The obtained HPL-CFs exhibited excellent antimicrobial activities against Escherichia coli (E. coli, Gram-negative bacteria), Staphylococcus aureus (S. aureus, Gram-positive bacteria), and Candida albicans (C. albicans, fungi) even when the CF was treated with HPL solution at the concentration of 0.5 wt %. HPL2.0-CFs maintained 98, >99, and >99% of antimicrobial ratios for E. coli, S. aureus, and C. albicans, respectively, after 50 equiv of domestic laundering cycles, surpassing the requirements of the AAA class. The halo method, cell compatibility, and skin irritation assays all prove the fine safety of HPL-CFs. This work demonstrates the great advantages of applying HPL in the antimicrobial finishing of fabrics.

“…Moreover, the special lines in the textile industry can be counted as another class of textile attributes. For example, the pad-dry-cure lines in the traditional finishing processes are very suitable for developing antiviral fabrics, − because of their accessibilities for large-scale production. In contrast, despite a large number of antiviral nanofibers being prepared using the electrospinning technique on a laboratory scale, − a large amount of commercial supply still faces great challenges.…”

The outbreak of COVID-19 provided a warning sign for society worldwide: that is, we urgently need to explore effective strategies for combating unpredictable viral pandemics. Protective textiles such as surgery masks have played an important role in the mitigation of the COVID-19 pandemic, while revealing serious challenges in terms of supply, cross-infection risk, and environmental pollution. In this context, textiles with an antivirus functionality have attracted increasing attention, and many innovative proposals with exciting commercial possibilities have been reported over the past three years. In this review, we illustrate the progress of textile filtration for pandemics and summarize the recent development of antiviral textiles for personal protective purposes by cataloging them into three classes: metal-based, carbon-based, and polymer-based materials. We focused on the preparation routes of emerging antiviral textiles, providing a forward-looking perspective on their opportunities and challenges, to evaluate their efficacy, scale up their manufacturing processes, and expand their high-volume applications. Based on this review, we conclude that ideal antiviral textiles are characterized by a high filtration efficiency, reliable antiviral effect, long storage life, and recyclability. The expected manufacturing processes should be economically feasible, scalable, and quickly responsive.

“…[24,[30][31] In addition, the peaks of the fine spectrum of the oxygen element on the coating surface at 531.7 and 531.6 eV can be proved to be ester C═O bonding, while this peak does not appear in the O 1s spectrum of the original cotton fabric (Figure 3d). [32] XPS results showed that the coating was grafted onto the cotton fiber by ester group. Based on the above analysis, it was concluded that CS@Cu-MOFs@SA and CS@Zn-MOFs@SA coatings were successfully prepared on the fabric surface.…”

There is an urgent need to develop a series of multifunctional materials with good biocompatibility, high mechanical strength, hemostatic properties, anti‐adhesion, and anti‐infection for applications in wound care. However, successfully developing multifunctional materials is challenging. In this study, two superhydrophobic composite coatings with good biocompatibility, high mechanical strength, strong antifouling and blood repellency, fast hemostasis, and good antibacterial activity were prepared on cotton fabric surface by simple, green, and low‐cost one‐step dip‐coating technology. The results discussed in the manuscript revealed that the two superhydrophobic composite coatings could maintain good mechanical stability, strong water repellency, and durability under various types of mechanical damage, high‐temperature treatment, and long‐term strong light irradiation. The coatings also exhibited good repellency to various solid pollutants, highly viscous liquid pollutants and blood. In vitro and in vivo hemostatic experiments showed that both composite coatings had good hemostatic and anti‐clot adhesion properties. More importantly, this superhydrophobic coating prevented bacterial adhesion and growth and released Cu2+ and Zn2+ ions and chitosan to achieve bactericidal properties, thereby protecting injured skin from bacterial infection. The two superhydrophobic coatings enhanced the anti‐fouling, anti‐adhesion, hemostatic, and antibacterial functions of blood‐repellent dressings and therefore have broad application prospects in medical and textile fields.This article is protected by copyright.
