Things of nature are clean by itself. There are no janitors in the woods, dusting the trees. While people use various cleaning treatments, nature applies an environmentally benign cleaning strategy. Drops of water on the lotus leaf shine with a sparkle, washing away the dirt from it more swiftly than any other plant. Nature has always been a source of positive inspiration to man. Researchers observed that wax and microscopic bumps on the surface of the leaf makes it to repel water. Water droplets rolling down from the lotus leaf collects the dirt particles and small insects on the top of the leaf, and effectively cleans the surface. Lotus leaves, through a complicated micro-to nano surface structure, repel dirt, and water. They found the means to transform nature into technology which gave way for the making of self cleaning, and soil, & water repellent textiles.

The traditional techniques demonstrated good effects but were not durable under conditions of intense use. Chemicals were used in the early 90s to exhibit water repellent character followed by wax later. Chemically treated fabrics became harsh and also resulted in a discoloration. Furthermore, there was no wash durability. The new approach has minimized the shortfalls in a significant way. Self cleaning and super hydrophobic micro to nano structured surfaces was observed in some plants. A nano-structured surface is created with super paramagnetic nano particles. This ferromagnetic fibre structuring with high energy magnetic field coil takes place after the spinneret, when the spin-melt is in a thermoplastic state, which allows for the stretching of filament.
