Plasma Sputtering for Fabrication of Antibacterial and Ultraviolet Protective Fabric

Abstract

In this study, we have used a DC magnetron sputtering system for creating antibacterial and ultraviolet protective cotton fabrics. A silver anode and cathode were used, and samples were placed on the anode. The cathode particles were scattered by attacking active ions, radicals, and electrons. Time of exposure and gas pressure was changed parameters of plasma. Silver particles were deposited on the both sides of cotton samples, and the antibacterial property has been developed, through sputtering of silver particles on fabric surfaces. ICP (Inductively Coupled Plasma) analysis was carried out to investigate the silver ion content on cotton fabrics. The antibacterial properties of the fabrics were connected with the presence of Ag on their surface. The antibacterial efficiency was determined by bacterial counting test. After plasma treatment, the physical and chemical properties of the fabrics were examined by surface analysis methods and textile technology tests. Also treated cotton fabrics had an excellent UV-blocking property. UPF value of the silver sputtered cotton fabric reached to 264. According to the standard, the treated cotton fabric can claim to be a ''UV Protective product''. The experimental work suggests that the change in properties induced by plasma can effect an improvement in certain textile products.

Preparation and Characterization of FC Films Coated on PET Substrates by RF Magnetron Sputtering

“…The magnetron sputtering technology can be used to prepare super-hard films, wearable and corrosion-resistant films, superconducting films, magnetic films, optical films, and other specific films [1]. It has been using the magnetron sputtering to deposit thin films on fabric to obtain functionalities, such as wettability, hydrophilicity, hydrophobicity, antibacterial property, and uvioresistant property [2][3][4][5][6][7][8][9].…”

Synthesis and application of UV ray’s protective mono azo acid dyes on Wool, Silk and Nylon

“…UV protection by fabrics has recently become the focus of great interest, particularly in connection with environmental degradation or ozone layer depletion. Clothing is perceived as a good means of sun protection, but not all apparel is sufficiently protective against UV radiation [22]. A key element in achieving the goal of reduced UVR exposure is making proper UV protective goods with good UPF protection > 40.…”

Effect of Mordant on UV Protection and Antimicrobial Activity of Cotton, Wool, Silk and Nylon Fabrics Dyed with Some Natural Dyes

“…UV-A causes little noticeable reaction on the skin but it reduces the immunological response of skin cells. UV-B is the most responsible for the growth of skin cancers [6][7][8][9][10][11][12][13]. In addition to the importance of avoiding exposure of human-skin to solar UV radiation, the dyed clothes are more UV protected than undyed ones [14][15][16][17].…”
