Development of Antiviral CVC (Chief Value Cotton) Fabric

Abstract

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.

Electrospun Filtering Membrane Designed as Component of Self-Decontaminating Protective Masks

“…Log reductions observed on the textile without ADBAC correspond to the natural decay of the virus when deposited on a surface. While exhibiting some virucidal activity, 0.4% w / v ADBAC nanofibers did not reach a 2 log reduction before 4 h of contact time; in contrast, at contact times of 1 h to 4 h, the antiviral activity of 1.4% w / v ADBAC nanofibers had significant values ranging from 99% to 99.9% (2 to 3 log), which is comparable to other antiviral textiles [ 68 , 69 , 70 ].…”

Functional Textile Materials for Blocking COVID-19 Transmission

“…Since the Middle Ages, a variety of textiles have been used as protective measures in response to various epidemics. , Predecessors utilized alternative applications of silk, waxed linen, or canvas textile products to cover the mouth and nose, which later developed into disposable masks and medical protective clothing . From a historical perspective, the plague doctor outfit appeared as a practical case of the theoretical full individual protection textile concept, which also comprised shoes, gloves, a robe, a shawl, and a hat, in addition to the mask .…”

“…Similarly, an antiviral PHMB coating was prepared as well, which has been applied in hotel and dormitory linen. 23 Indeed, since the outbreak of COVID-19, various products suitable for the pad-dry-cure process emerged rapidly. 228−231 Recently, bioactive reagents such as functionalized polyurethane 232 and lignin 189 have been utilized to impart textiles with antiviral functionality, and mass production was achieved by a well-known pad-dry-cure process.…”

Rechargeable Potent Anti‐Viral Cotton Grafted with a New Quaternized N‐Chloramine

“…Common strategies for developing antimicrobial textiles involve impregnating or coating the textiles with an active agent such as copper nanoparticles, copper oxide particles, copper sulfide, benzalkonium chloride, polybiguanide, iodine complexed with N-vinylpyrrolidone, salt coating, licorice root extract, silver nanoparticles, titanium dioxide, aluminum and aluminum oxide, anionic photosensitizers (rose Bengal and sodium 2-anthraquinone sulfate), zinc oxide, or graphene-based nanomaterials such as graphene oxides, nanofibers, nanosheets, and nanoparticles. [1,2,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] However, such strategies that rely on impregnating surfaces with antimicrobial agents are subject to leaching of the active compound, posing health risks to the wearer as well as causing environmental contamination through laundering and textile end-of-life disposal. [18] Covalent surface modification of textiles with antimicrobial agents can mitigate these risks.Covalent modification of antimicrobial polymers onto textile surfaces can be achieved by a variety of methods, such as graft polymerization via chemical free radical initiators, click chemistry, or radiation-induced graft polymerization.…”
