The synthetic fibers are widely used in recent years in automotive industry. 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 natural stains like tea, coffee and ketchup stain on nylon-6 and the effect of daylight time exposure from 6 to 24 hours on stained samples was reported. Stain of natural materials on corona with nano TiO2 treated nylon removed almost completely after 24 hours under daylight irradiation.
