Enhancement of Thermal Stability, Flame Retardancy, and Antimicrobial Properties of Cotton Fabrics Functionalized by Inorganic Nanocomposites

Abstract

In this investigation, various metal oxide (ZrO2, MgO, TiO2) nanoparticles were prepared using the hot-air spray pyrolysis method. The prepared nanoparticles were characterized using the X-ray diffraction (XRD) technique, scanning electron microscopy (SEM), and transmission electron microscopy. The colloidal silica (SiO2) sol was prepared using the sol–gel method, mixed with various metal oxides (ZrO2, MgO, TiO2). Uncoated cotton fabrics were separately impregnated with the prepared nano­(composite) sols followed by the pad-dry-cure method. The structural analysis of the coated and uncoated fabrics was performed using XRD. The surface morphology of the coated and uncoated cotton fabrics was analyzed using SEM. The elemental analysis using energy-dispersive spectroscopy confirmed the presence of nanoparticles along with cellulose on the surface of the fabric. The thermal stability and flame retardancy properties and residue of the coated and uncoated fabrics were studied. The coated cotton fabrics showed better antibacterial activity against Staphylococcus aureus and Escherichia coli. The biocompatibility performance of the coated fabrics was in the order TiO2/SiO2 > MgO/SiO2 > SiO2 > ZrO2/SiO2.

Quantitative evaluation of antibacterial activities of nanoparticles (ZnO, TiO2, ZnO/TiO2, SnO2, CuO, ZrO2, and AgNO3) incorporated into polyvinyl butyral nanofibers

“…It was found that carbon–TiO 2 /ZnO has a stronger antimicrobial effect than a TiO 2 /ZnO nanocomposite, and the growth of E. coli on the control plate decreased after ultraviolet irradiance . Rajendran et al prepared cotton fabrics impregnated with zirconium dioxide (ZrO 2 ), magnesium oxide (MgO), and TiO 2 NP sols, which are colloidal silica (SiO 2 ) mixed with metal oxides, and compared their thermal, flame retardance and antimicrobial properties . ZnO/SnO 2 (tin oxide) hybrid nanostructure films were prepared to enhance the antibacterial activity against Gram‐negative E. coli .…”

Development of flame retardant cotton fabric based on ionic liquids via sol-gel technique.

“…However, cotton functionalized with different ionic liquids does not flame during and after the removal of the flame. The coated CO slowly ignitesthe flame and keeps burn slowly for 173s (see [14,15].…”

Antibacterial Cotton Fabrics Coated by Biodegradable Cationic Silicone Softeners

“…The detrimental effects of bacteria can be mitigated via the use of a broad‐spectrum antimicrobial finishing agent in the treatment of textiles. The incorporation of antibacterial moieties into fabrics has been widely adopted and is typically achieved via either chemical or physical treatment, such as the incorporation of metal and metal oxide nanoparticles (Fu et al, ; Goli et al, ), nanocomposite particles (Rajendran et al, ), organic quaternary ammonium salts (Lu et al, ; Yu et al, ), guanidine (Li et al, ), chitosan (Feng et al, ), and so on. Therefore, considerable progress has recently been made in terms of the development of antibacterial fabrics.…”
