In vitroassessment of antibacterial potential and mechanical properties of Ag-TiO₂/WPU on medical cotton optimized with response surface methodology

Potent environmental-friendly virucidal medical textiles against coronavirus to combat infections during the COVID-19 pandemic

“…The elongation at break slightly decreased with increasing contents of TiO2@Ag NPs as the presences of these NPs resulted in less deformation than that of pure WPU. 19,34 Washing fastness…”

“…The enhanced antibacterial efficiency can be explained by a combination of the reactive oxygen species (ROS) generated by the TiO 2 , and the release of Ag + from the photocatalytic activity. 11,15,19,20 So far, there have been a few studies that were conducted and reported based on effectiveness of silver-doped TiO 2 against virus. 9,21,22 The Ag/TiO 2 film was proved to be extremely effective against H1N1 virus and enterovirus type 71, with almost a 100% virucidal efficacy.…”

Silver-based nanocomposite for fabricating high performance value-added cotton

“…Many attempts have been conducted to endow cotton fabrics with multifunctionalities, including self-cleaning, UV protection, electric conductivity and antimicrobial capability. Ag-based nanocomposites with other metal or metal oxide have been designed to fabricate high performance value-added cotton fabrics, such as antimicrobial ZnO (El-Nahhal et al 2013Selvam et al 2012;Gao et al 2019) or TiO 2 (Doganli et al 2016;Chitichotpanya et al 2019;Yuranova et al 2006). CuO (Ma et al 2013;Perelshtein et al 2013), Cu 2 O (Sing et al 2013;Sedighi et al 2014b;Montazer et al 2015) or Cu NPs (Xu et al 2018c;Sedighi et al 2014a) has also been immobilized onto the fabric to offer durable antimicrobial properties with or without binders.…”

Green Dyeing and Antibacterial Treatment of Hemp Fabrics Using Punica granatum Peel Extracts

“…Pomegranate peel is a rich source of tannins, phenolics, and alkaloids. Tannins are used as coloring compounds and contain both hydrophobic (aromatic) and hydrophilic (-OH) groups, while hemp fabrics also contain hydrophilic (-OH) cellulose groups [34][35][36]. The mordant, AlK(SO 4 ) 2 , which is used to fix tannin onto the hemp fabric, does so by forming an insoluble complex.…”

“…All color staining values were rated as good to excellent (4-5), except those of the acrylic fabric which were rated as fair (3). This suggested that formation of the tannin-mordantacrylic fabric complex was more stable than that of the cellulose-based hemp fabric [34,35]. Color fastness to crocking was also tested.…”
