“…Lyocell is the first successful technology of cellulosic fibers by direct dissolution, resulting in fibers with exceptional properties, making it a serious competitor to the Viscose process, since it is more environmentally friendly (White, 2001;Peng et al, 2017). Lyocell fiber has higher tenacity (especially wet tenacity), higher modulus, lower shrinkage, better thermal stability, higher crystallinity, and greater degree of orientation, than Viscose (Edgar and Zhang, 2020). The Lyocell fiber market is estimated to grow from 760 million € in 2016 to over 1.35 billion € by 2024 (Pulidindi and Chakraborty, 2016).…”

There is an emerging environmental awareness and social concern regarding the environmental impact of the textile industry, highlighting the growing need for developing green and sustainable approaches throughout this industry’s supply chain. Upstream, due to population growth and the rise in consumption of textile fibers, new sustainable raw materials and processes must be found. Cellulose presents unique structural features, being the most important and available renewable resource for textiles. The physical and chemical modification reactions yielding fibers are of high commercial importance today. Recently developed technologies allow the production of filaments with the strongest tensile performance without dissolution or any other harmful and complex chemical processes. Fibers without solvents are thus on the verge of commercialization. In this review, the technologies for the production of cellulose-based textiles, their surface modification and the recent trends on sustainable cellulose sources, such as bacterial nanocellulose, are discussed. The life cycle assessment of several cellulose fiber production methods is also discussed.

“…Suitable antibacterial agents must be able to withstand certain temperatures and conditions to be incorporated into RC products, such as during cellulose dissolution (specific temperature applied) or regeneration [ 130 ]. As an example, epsilon-poly-L-lysine (EPL), a broad-spectrum antibacterial agents, is used alongside the fabrication of RC beads [ 131 ].…”

Regenerated Cellulose Products for Agricultural and Their Potential: A Review

Cellulose is one of the most abundant natural polymers with excellent biocompatibility, non-toxicity, flexibility, and renewable source. Regenerated cellulose (RC) products result from the dissolution-regeneration process risen from solvent and anti-solvent reagents, respectively. The regeneration process changes the cellulose chain conformation from cellulose I to cellulose II, leads the structure to have more amorphous regions with improved crystallinity, and inclines towards extensive modification on the RC products such as hydrogel, aerogel, cryogel, xerogel, fibers, membrane, and thin film. Recently, RC products are accentuated to be used in the agriculture field to develop future sustainable agriculture as alternatives to conventional agriculture systems. However, different solvent types and production techniques have great influences on the end properties of RC products. Besides, the fabrication of RC products from solely RC lacks excellent mechanical characteristics. Thus, the flexibility of RC has allowed it to be homogenously blended with other materials to enhance the final products’ properties. This review will summarize the properties and preparation of potential RC-based products that reflect its application to replace soil the plantation medium, govern the release of the fertilizer, provide protection on crops and act as biosensors.

“…The affinity of selected antibacterial agents to fibers plays a vital role in the durability of antibacterial fabrics. In this regard, the hydrophilic polymeric antibacterial agents provide a better choice than the inorganic metal nanoparticles [ 6 , 7 ]. A wide variety of polymeric antibacterial agents have been developed, ranging from naturally derived biopolymers, such as chitosan and starch and synthetic polymers including quaternary ammonium salts, polybiguanide, triclosan and N-halamine, to inorganic metal nanoparticles, such as TiO 2 , ZnO and silver nanoparticles [ 6 , 7 ].…”

It has been reported that some antibacterial agents, e.g., triclosan and copper-based compounds, have been also used for the development of antiviral fabrics due to their antiviral activities [ 8 ].…”

The outbreak of COVID-19 has already generated a huge societal, economic and political losses worldwide. The present study aims to investigate the antiviral activity of Poly(hexamethylene biguanide) hydrochloride (PHMB) treated fabric against COVID-19 by using the surrogate Feline coronavirus. The antiviral analysis indicated that up to 94% of coronavirus was killed after contacting the CVC fabric treated with PHMB for 2 h, which suggests that PHMB treated fabric could be used for developing protective clothing and beddings with antiviral activity against coronavirus and can play a role in fighting the transmission of COVID-19 in the high-risk places.
