“…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.

“…A type of cotton fibers that contains Cu NPs possesses anti-influenza A virus properties. It was revealed that the antiviral activity values of the produced fibers were more than the value of reference 3.0, which suggests a high antiviral characteristic (Miyakawa et al, 2021). Li et al combined the antimicrobial properties of Cu and chlorine dioxide into polymeric micelle formulations (Li et al, 2018).…”

Drug-resistant bacteria and highly infectious viruses are among the major global threats affecting the human health. There is an immediate need for novel strategies to tackle this challenge. Copper-based nanoparticles (CBNPs) have exhibited a broad antimicrobial capacity and are receiving increasing attention in this context. In this review, we describe the functionalization of CBNPs, elucidate their antibacterial and antiviral activity as well as applications, and briefly review their toxicity, biodistribution, and persistence. The limitations of the current study and potential solutions are also shortly discussed. The review will guide the rational design of functional nanomaterials for antimicrobial application.

“…Copper nanoparticles were formed inside cotton fibers by in situ microwave heating with antiviral properties against influenza A virus, but their durability needs to be further improved. 22 sition technologies, 23 solution-based technologies, 24 autocatalytic electroless deposition, 25 and polymer-assisted electroless deposition 26 ) show great potential for developing conductive fibers, these metal coatings suffer from poor adhesion, shortterm environmental stability, and failure to achieve flame retardance in harsh conditions. 27 In principle, cellulose derived from vegetation has the advantages of renewability, inherent biocompatibility, and degradability, which are widely used in textile, food, pharmaceutical, and biomedical device industries.…”

“…For instance, Li et al constructed biomimetic sensors by the layer-by-layer method with graphene sheaths on spidroin fibers but with low electrical conductivity (95.3 S m –1 ). Copper nanoparticles were formed inside cotton fibers by in situ microwave heating with antiviral properties against influenza A virus, but their durability needs to be further improved . Although metallization methods (vacuum deposition technologies, solution-based technologies, autocatalytic electroless deposition, and polymer-assisted electroless deposition) show great potential for developing conductive fibers, these metal coatings suffer from poor adhesion, short-term environmental stability, and failure to achieve flame retardance in harsh conditions …”

Nanocomposite conductive fibers are of great significance in applications of wearable devices, smart textiles, and flexible electronics. Integration of conductive nanomaterials into flexible bio-based fibers with multifunctionality remains challenging due to interface failure, poor flexibility, and inflammability. Although having broader applications in textiles, regenerated cellulose fibers (RCFs) cannot meet the requirements of wearable electronics owing to their intrinsic insulation. In this study, we constructed conductive RCFs fabricated by coordinating copper ions with cellulose and reducing them into stable Cu nanoparticles coated on their surface. The Cu sheath offered excellent electrical conductivity (4.6 × 10 5 S m −1 ), electromagnetic interference shielding, and enhanced flame retardance. Inspired by plant tendrils, the conductive RCF was wrapped around an elastic rod to develop wearable sensors for human health and motion monitoring. The resultant fibers not only form stable conductive nanocomposites on the fiber surface by chemical bonds but also exhibit a huge potential for wearable devices, smart sensors, and flame-retardant circuits.
