Sonochemical Coating of Ag-TiO 2 Nanoparticles on Textile Fabrics for Stain Repellency and Self-Cleaning- The Indian Scenario: A Review

Surface modification is an important element of textile manufacturing. The final properties of a textile material are critical in determining how they perform for their given end use. More recently, botany and nanotechnology have united to explore not only the beauty and cleanliness of the leaf, but also its lack of contamination and bacteria, despite its dwelling in dirty ponds. On the basis of lotus leaf concept scientist developed a new concept “Self cleaning textile” the textile surface which can be cleaned itself without using any laundering action. In this paper, the role of silver- Titania nanoparticles synthesized and deposited on different types of fabrics using ultrasound irradiation under an atmosphere of argon gas and decreasing both the cavitational threshold and intensity of ultrasound power has been reviewed. The excellent antibacterial activity of the Ag–Titania fabric composite against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) cultures also reviewed with reference to Indian scenario.
