Self-cleaning of methylene blue on corona treated nylon-6 fiber with anatase titanium dioxide under UV light

The synthetic fibers are widely used in recent years. Producing textiles with self-cleaning properties is a significant issue in the textile industry. In recent decades, titanium dioxide is known as the best option for photocatalytic applications of self-cleaning. Nano TiO2 has a high activity due to the ratio of surface area to its volume which is shown the substantial oxidative activity under light. In this research, corona plasma was used as a pre-treatment on nylon fabric. Nano TiO2 particles which had been sonicated, coated onto untreated and treated nylone-6 fabrics and then fabrics were cured at temperatures 90ºC for 5 minutes. In this research, self-cleaning capacity was determined based on discoloration methylene blue on nylon-6. Effect UV time exposure from 6 to 24 hours on stained samples were assessed by ΔE. Stain of methylene blue on corona with nano tio2 treated nylon removed almost completely after 24 hours under UV light. Reflectance spectra and K/S of stain are confirmed corona and TiO2 treated nylon for 24 hours has best effects for removal color
