Abstract

Water and soil repellency has been one of the major targets for fiber and textile scientists and manufacturers for centuries. Nano science is employed for this type of problems. From the nano science self cleaning is the wonderful technology for dirt-free with other functional finishes. So, through this paper we deals with various mechanisms of self-cleaning and the coatings, manufacturing methods, and also various functional finishes like antimicrobial; UV ray finishes which can be imparted with the major advantages than the other conventional finishes and application area of this technique. Connection to this limitation, problems with this technique and recommendations for the purpose of bringing out new ideas which is incorporated in the self cleaning garments.

Introduction

Nature has already developed an elegant approach that combines chemistry and physics to create super repellant surfaces as well as self cleaning surfaces. "Lotus leaves" is the best example of self cleaning surfaces. The technology of self-cleaning coatings has developed rapidly in recent years. As a commercial product, their potential is huge and their market truly global. Because of the wide range of possible applications. The concept of self cleaning textiles is based on the lotus plant whose leaves are well-known for their ability to self-clean by repelling water and dirt. Now day's peoples are very busy in their work that they do not have time for clean their daily wear cloths also people who are working in kitchens having headache to wash their garments. Also military peoples have to survive in such drastic condition that they cannot wash their cloths. Nano technology provides a new concept self cleaning textiles which gives self cleaning as well as fresh cloths every day, this not only technically benefited but techno economically also benefited. The field of self-cleaning coatings is divided into two categories: hydrophobic and hydrophilic. These two types of coating both clean themselves through the action of water, the former by rolling droplets and the latter by sheeting water that carries away dirt. Hydrophilic coatings, however, have an additional property: they can chemically break down adsorbed dirt in sunlight.
