The global widespread of coronavirus disease 2019 (COVID-19) has caused shortage of medical face masks and led to developing of various types of cloth masks with different levels of protection and comfort to meet the market demands. Breathing comfort is a significant aspect that should be considered during the design of cloth masks along with the filtration efficiency; otherwise, the wearer will feel suffocated. In this work, different types of cotton and polyester knitted fabrics blended with spandex yarns were produced and treated with silver nanoparticles to be used as antiviral cloth masks. Scanning electron microscope, transmission electron microscope, and EDX were used to characterize the silver nanoparticles (AgNPs). Antiviral activity was assessed against SARS-CoV-2 coronavirus as well. The influence of using different fabric materials, number of layers, and hybrid layers on their air permeability and breathability were investigated to evaluate the comfortability of the cloth masks. Physiological impacts of wearing the cloth masks were evaluated by measuring oxygen saturation of hemoglobin and heart rate of the wearers while doing various activities. The results indicated that AgNPs have low cytotoxicity and considerable efficiency in inhibition of SARS-CoV-2. Adding spandex yarns with different count and ratios reduced the porosity and air permeability of the fabrics. Moreover, the combination of three hybrid layers’ mask made of polyester fabric in the outer layer with 100% cotton fabric in the inner layer showed high comfortability associated with high air permeability and breathability. Also, wearing these masks while doing activities showed no significant effect on blood oxygen saturation and heart rate of the wearers.

“…The treated sample was rinsed thoroughly with water and neutralizing via acetic acid (1 g/L) for about 5 min at 40 ºC. The dyed fabrics samples were rinsed with cold water, washed in a bath containing 3 g/L detergent (Hostapal CV, Clariant) at 50 °C for 30 min, followed by rinsing with water and allowed to dry at room temperature [25].…”

In the present work, novel synthesis of subphthalocyanine chlorides was performed and used for dyeing polyester and wool fabrics. The chemical structure of subphthalocyanine was confirmed and evaluated using 1 H NMR, FTIR, element analysis and mass spectra. The morphological properties of fabrics before and after dyeing were studied using SEM and EDX measurements. The Color strength (K/S) measurements of the dyed fabrics and their color fastness to rubbing, washing, and perspiration, and light were investigated. Moreover, the UV protection measurement (UVP) was tested for the dyed fabrics. The results indicated that the dyed fabrics showed remarkable higher K/S value than un-dyed fabrics. The dyed of both polyester and wool fabrics showed improved UVP as 16.2 and 49.1 values compered to un-dyed fabrics 5.5 and 22.2, respectively. The results also indicated that, the fastness properties of dyed wool fabric and polyester have good to very good to perspiration rubbing, washing, light and rubbing fastness. This work provides simple and efficient process for dyeing of polyester and wool fabrics for smart functional fabrics.

“…• The ultraviolet protection factor (UPF) was estimated using a UV-Shimadzu 3101-PC-Spectrophotometer in accordance with the Australian/New Zealand Standard (AS/NZS-4399-1996). • Fastness to washing was measured according to launder-O-meter AATCC Test method 61-2013 [30]. Light, rubbing, and perspiration measurements were done according to the standard methods of AATCC 1993a, AATCC 1993b, and AATCC 1993c, respectively [31].…”

The current study concerns the valorization of waste rice hulls into value-added materials. To achieve this goal, first, the extraction route of mesoporous silica nanoparticles (SiO2NPs) from rice hulls using citric acid as a carbon template was compared with that prepared by conventional methods of incineration only. Both routes were performed at different temperatures of 600 and 700°C, and the fabricated SiO2NPs were studied by N2 physisorption isotherm, X-ray diffraction (XRD), Fourier transform infrared (FTIR), dynamic light scattering (DLS), and thermogravimetric (TG) analyses. The results show the influence of both routes and temperature on the porous structure, surface area, and charge of as-fabricated SiO2NPs. Furthermore, the physico-chemical features of as-prepared mesoporous SiO2NPs were utilized, in a facile and green way, to prepare silver NPs with high anti-microbial activity. The results were validated by the tools of UV-visible, FTIR, XRD, and XPS spectroscopy. Finally, the fabricated silver-doped mesoporous SiO2NPs were used as auxiliary additives through one-pot printing of different types of fabric (i.e., polyester (synthetic fabric), cotton (natural fabric), and cotton/polyester (blended fabric)). The EDX mapping of the pigment-printed fabrics with Ag-doped SiO2NPs exhibited the homogeneous distribution of Ag and Si atoms together with C and O throughout the fabric matrix. Interestingly, the pigment-printed fabrics with Ag-doped SiO2NPs demonstrated superior antibacterial activity, ultraviolet protection factor (UPF), and color characteristics in comparison to the conventional dyeing component.
