Novel corona discharge treatment of cotton fabric with Cu and ZnO nanoparticles

Abstract

The aim of this study was to investigate coating of copper and zinc oxide nanoparticles on cotton fabric by using corona discharge in two ways of pre-treatment and post-treatment. In pre-treatment method, cotton fabrics were modified by corona discharge before coating separately with nanoparticles. In post-treatment, cotton fabrics were coated separately with ZnO and Cu nanoparticles before treating by corona discharge. Self-cleaning properties of treated fabrics were determined by staining methylene blue dye. The antibacterial tests, Scanning electron microscopy and FTIR/ATR analysis were carried out to observe antibacterial performance, surface morphology and analyze the surface chemical structure, respectively. Atomic absorption spectroscopy and water droplet adsorption were used for the determination of metal ion content, and water adsorption. Results showed that by pre-treatment method of corona discharge, absorption of copper nanoparticles was increased, and self-cleaning effect and antibacterial performance of copper nanoparticles were higher than post-treatment. ZnO nanoparticles had highest self-cleaning and antibacterial effect by pre-treatment method. By post-treatment method, the photocatalyst activity of ZnO nanoparticles was decreased.     

Investigating the effect of corona treatment on self-cleaning property of finished cotton fabric with nano titanium dioxide

This research aims to create the durable self-cleaning property on cotton fabric using nano titanium dioxide and corona treatment as a dry and environmentally friendly process. In this regard, cotton fabrics were investigated under corona treatment with intensities of 2 and 3 A for 1, 3, and 5?min of irradiation. The treated samples with 0.1, 0.5, 1, and 1.5 on weight of bath percent were cured by nano titanium dioxide to obtain the highest self-cleaning property. The treated cotton fabrics, which were stained with direct green 6, were exposed to 20 and 400?W of UV radiation and their self-cleaning property was examined, and the results were reported. In addition, using corona treatment helped to stabilize the nano titanium dioxide on the cotton fabric surface even after 50 washing cycles. Through SEM images, Thermo Gravimetric Analysis plots, and XRD patterns, the presence of nano titanium dioxide on the surface of the treated cotton samples after washing was verified. Also, the tensile strengths of TiO₂-coated cotton fabrics were measured.     

Study on property of PANI/PET composite conductive fabric

Polyester (PET) fabric was treated with alkali and low-temperature plasma. After that, polyaniline (PANI)/PET composite conductive fabric was prepared through in situ polymerization using aniline as monomer. The structural properties, conductivity, mechanical properties, and wash fastness of PANI/PET composite conductive fabric were studied and characterized. The results showed that the optimal polymerization conditions: the molar ratio of ammonium persulfate and aniline is 1:1 and the concentration of sulfuric acid is 1?mol/L. Under optimum conditions, the surface resistivity of PANI/PET composite conductive fabric was about 170?Ω. PANI particles enter into the fiber and the crystallinity of PANI/PET composite conductive fabric declines and amorphous region of PANI/PET composite conductive fabric increases. The breaking strength and breaking elongation of PANI/PET composite conductive fabric decrease compared with PET fabric. After being washed five times, the surface resistivity of PANI/PET composite conductive fabric is stable at 1450?Ω.
