Use of zinc oxide nano particles for production of antimicrobial textiles

Abstract

The application of nanoscale materials and structures, usually ranging from 1 to 100 nanometers (nm), is an emerging area of nanoscience and nanotechnology. Synthesis of noble metal nanoparticles for applications such as catalysis, electronics, textiles, environmental protection, and biotechnology is an area of constant interest. Recently, an awareness of general sanitation, contact disease transmission, and personal protection has led to the development of antimicrobial textiles. The development of antimicrobial cotton fabrics using Zinc oxide nanoparticles has been investigated in this present work. The ZnO nanoparticles were prepared by wet chemical method and were directly applied on to the 100% cotton woven fabric using pad-dry-cure method. The antibacterial activity of the finished fabrics was assessed qualitatively by agar diffusion and parallel streak method, quantitatively by percentage reduction test. The topographical analysis of the treated fabric and untreated fabric were studied and compared. The results show that the finished fabric demonstrated significant antibacterial activity against S. aureus in both qualitative and quantitative tests. The SEM analysis revealed the embedding of ZnO nanoparticles in treated fabrics. The wash durability study of the treated fabric was also carried out and found to withstand up to 25 wash cycles.

ANTIBACTERIAL EFFICIENCY OF MODAL FABRIC TREATED WITH OXIDES OF Ti/Si/Zn NANOCOMPOSITES

“…10 A significant result was observed in the zinc oxide nanoparticle treated cotton fabrics against S.Aureus. 11 In the ZnO/TiO2 composite treated nylon/cotton blended fabric, the highest antibacterial property against E.coli and S.Aureuswas obtained at a concentration of 60 ppm. 12 Many researchers have worked on the antibacterial modification of textiles on natural fibers such as cotton and wool, cotton/polyester, nylon/cotton.…”

Anti-Bacterial Activity Studies on Textile Modified With Silver Metal, Copper, Zinc and Magnesium Oxides Nanoparticles

“…25 Zinc nitrate and sodium hydroxide were used as precursors while soluble starch was added as stabilizing agent. Soluble starch (0.1 %) was dissolved in 500 ml of distilled water then zinc nitrate was added.…”

“…7 Recently, much attention has been paid on the loading of metal and metal oxides nanoparticles (NPs) onto cotton substrate due to their potential applications. [8][9][10][11][12] The modified cotton fabrics have exhibited excellent antimicrobial activities against bacteria. 7 There is a growing awareness of the use of antibacterial fabrics in the form of medical clothes, protective garments, and bed spreads to minimize the chance of the nosocomial infections.…”

“…Zinc oxide has also been explored as a powerful antibacterial agent. [7][8][9][10][11][12][13] The relation between the antibacterial activity versus the ZnO particles size was studied. 17 It was observed that the antibacterial activity is inversely proportional to the nanoparticles' size.…”

“…Due to this property it activates the wound healing process by delivering zinc ions to the wound and allowing them to remain there for an extended period of time [15]. Though zinc accelerates the re epithelization of the skin, the exact mechanism is not really known [16][17][18]. Herb selected for this study was cynodon dactylon.…”
