ABSTRACT: 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.
