Effect of corona treatment on absorption nano TiO2 on nylon-6

This research aims to assess the effect of corona discharge on the TiO2 absorption. Corona treatment is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. It was found that the treatment of nylon-6 fabrics with corona discharge brings about some physical and chemical changes on the surface layer, which results in significant changes in the performance properties of fabrics. Corona treated nylon was coated with nano TiO2. Field Emission Scanning Electron Microscope (FESEM) was used. Some properties of the treated fabrics such as anti- microbial testing, Reflectance and bending length of samples were investigated. FESEM showed a uniform layer of nano TiO2 formed on corona treated nylon which caused lower bending length and softer handle. These treated nylon show positive antimicrobial activity against gram-negative Escherichia coli and gram positive Bacillus
