Blocking ultraviolet and anti-staining for cotton fabric 100% using nano titan dioxide

Abstract

Nowadays, customers have an increased demand for casual clothes and clothes with additional functions such as anti-staining, anti-ultraviolet (UV), and flame-retardant without losing comfort when wearing them. Some rays from the sun, especially UV rays (i.e., UVA and UVB) are harmful to human health. At high intensity, UV rays can cause sunburn, increasing the possibility of getting cancer. UV radiation damages the skin and destroys skin cells. Fabrics that not only have the ability to block UV rays but also have anti-staining ability are being studied more and have high competitive advantages over fabric items when people pay more and more attention to beauty and health. Using nano TiO2 to complete UV protection is a suitable method due to its stability, non-toxicity, and wide application technology. Therefore, this research is performed to finish blocking UV, anti-staining treatment on 100% cotton fabric with nano TiO2 using the popular method in textile finishing of pad-dry-cure aim to attach bonding chemicals to the fabric under the influence of technological parameters as follows: concentration of nano TiO2, pick-up level, processing temperature, and processing time are different. From there, we can choose the most optimal treatment method for the bifunctional finishing cotton fabric to provide to the textile market.
