| Abstract | ||
| Cotton textiles gain self-cleaning properties through nanotechnology. The concept of self-cleaning is inspired by natural phenomena observed in various surfaces, such as lotus leaves. Lotus leaves possess a hydrophobic surface due to waxy coatings, allowing them to thrive in dirty environments while maintaining purity. Nanoparticles like titanium dioxide (TiO2) are used in textile finishing to achieve self-cleaning abilities. When exposed to UV light, TiO2-coated cloth exhibits photocatalytic capabilities that break down stains and colors. The two primary methods of self-cleaning are hydrophobicity and hydrophilicity, where water rolling droplets and sheeting water clean hydrophobic surfaces, while hydrophilic materials chemically break down dirt when exposed to sunlight. The self-cleaning mechanism of lotus leaves is attributed to their superhydrophobic nature, hierarchical structures, and microscopic bumps that allow water droplets to remove contaminants. | ||
