“…In Figure 3 a, the broad XPS spectrum of the PES/CO fabric shows two peaks with binding energies at 532.5 and 284.7 eV corresponding to oxygen (O1s) and carbon (C1s), respectively, attributed to cotton and polyester fibers [ 41 , 42 ]. The binding energy around 932 eV is assigned to the photoelectron peak of copper (Cu 2p) [ 43 ].…”

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and healthcare-associated infections (HAIs) represent severe problems in health centers and public areas. Polyester/cotton (PES/CO) blend fabrics have been functionalized with copper oxides on an industrial scale. For functionalization, the impregnation dyeing technique was applied. The functionalized samples were tested virologically against SARS-CoV-2 and human coronavirus (229E) according to ISO 18184-2019 and microbiologically against Escherichia coli (ATCC 25922) bacteria according to ASTM E2149-2013. The results show that the fabric functionalized with copper oxides inactivated both viruses after 30 min of exposure, presenting excellent virucidal activity against 229E and SARS-CoV-2, respectively. Furthermore, its inactivation efficiency for SARS-CoV-2 was 99.93% and 99.96% in 30 min and 60 min exposure, respectively. The fabric inhibited bacterial growth by more than 99% before and after 10 and 20 washes. In conclusion, 265 m of PES/CO fabric (wide 1.7 m) was functionalized in situ on an industrial scale with copper oxide nanoparticles. The functionalized fabric presented virucidal and bactericidal properties against SARS-CoV-2 and Escherichia coli.

“…23−26 Despite their outstanding potential, the major challenge associated with the fabrication of N-halamine-modified PET fabrics is the intrinsically chemical inert property of the PET fibers. 27,28 In the previous work, a halamine precursor monomer, 3-allyl-5,5-dimethylimidazolidine-2,4-dione (ADMH), was co- valently bonded to the PET fabric through a typical "pad-drycure" process, demonstrating an industrially scalable methodology to produce a halamine-based biocidal PET fabric (PET-g-ADMH). 29 However, the grafting ratio of ADMH was not desirable due to the self-inhibiting effect of the allyl structure and poor affinity of the reaction system, limiting the biocidal activity of the PET-g-ADMH fabric against pathogens.…”

“…N -Halamine, with high biocidal efficacy, broad killing spectrum of pathogens, and ease of chlorine rechargeability, which has been successfully applied on cotton fabrics and olefin nonwovens, is a great promise to be incorporated with PET fabrics for constructing bioprotective medical scrubs. − Despite their outstanding potential, the major challenge associated with the fabrication of N -halamine-modified PET fabrics is the intrinsically chemical inert property of the PET fibers. , In the previous work, a halamine precursor monomer, 3-allyl-5,5-dimethylimidazolidine-2,4-dione (ADMH), was covalently bonded to the PET fabric through a typical “pad-dry-cure” process, demonstrating an industrially scalable methodology to produce a halamine-based biocidal PET fabric (PET-g-ADMH) .

Embedding medical scrubs with robust biocidal functions could potentially reduce pathogen cross-contamination and healthcare-associated infections. Here, a halamine precursor monomer, 1-acryloyl-2,2,5,5-tetramethylimidazolidin-4-one (ACTMIO), was covalently grafted to a poly(ethylene terephthalate) (PET) fabric, which is a common textile material used in medical scrubs, via a controlled free radical graft polymerization reaction using a "paddry-cure" finishing process. Based on a computational model and Hansen solubility theory, an ideal free radical reaction system was designed and implemented. The obtained ACTMIOgrafted (H-PET-g-ACTMIO) fabrics exhibited high grafting ratios of the monomers, desired properties of improved hydrophilicity, large active chlorine capacity, promising chlorine rechargeability, and desirable washing durability due to the robust covalent bonds between halamine moieties and PET fabrics. The chlorinated H-PET-g-ACTMIO fabric demonstrated powerful and regenerable biocidal performance against pathogenic bacteria, revealing the great application potential as a bioprotective medical textile. In addition, the successful application of Hansen solubility theory in surface modification of chemically inert polyester fibers provides a good example of controlling free radical polymerization reactions on textile materials.

“…It is urgent to develop a new dipping system instead of the resorcinol–formaldehyde system. In recent years, there are several studies on RF-free dipping systems for different fiber cords, including a mussel-inspired polydopamine (PDA) system, epoxy resin system, phenol-amine. − The Mussel-inspired PDA system of nylon-66 fiber cords cannot achieve the RFL treatment level of the interfacial adhesion effect. The epoxy resin system and the phenol-amine system were used on polyester fabric and aramid fiber, respectively, and the interfacial adhesion was close to the RFL treatment level.…”

Fiber-reinforced rubber composites (FRRC) are widely used as load-carrying and anti-pressure products. Resorcinol−formaldehyde−latex (RFL) dipping is widely used to improve interfacial adhesion between fiber and rubber in industry. Unfortunately, high volatility and toxicity of RFL do great harm to humans and the environment during the open dipping process. In this work, a phloroglucinol−terephthalaldehyde−latex (PTL) dipping system based on a low-toxic and low-volatile resin was developed to achieve equivalent interfacial adhesion instead of RFL ones. The reaction mechanism, chemical structure, and wettability changes on the Nylon-66 (PA66) fiber surface were characterized. The effect of the phloroglucinol/terephthalaldehyde (P/T) ratio on the dip pick-up, morphology of the fiber surface, and interfacial structure of FRRC was investigated to expound the interfacial adhesion mechanism. At the optimum P/T ratio (1/2.2), a dipping layer with uniform and suitable dip pick-up is achieved on the fiber surface, which ensures the formation of an appropriate graded interfacial layer with enough crosslinking density and modulus, under the synergistic effect of co-vulcanization with rubber, and accordingly strengthens interfacial adhesion. The dipped fiber possesses excellent interfacial adhesion, dynamic fatigue life, and storage stability at the RFL level. This new dipping system is environmentally friendly and easy to scale up without making any change in the process and equipment.
