Wrinkle Resistance: In order to impart wrinkle resistance, normal procedure is to use resin precondensates. However, to overcome the limitations of resin, nano Titanium dioxide and nano silica are employed using polycarboxylic acid as a catalyst under UV radiation to catalyze the cross linking reaction between cellulose molecules and the acid. On the other hand, the application of nano-silica with maleic anhydride showed successful improvement in the wrinkle resistance of silk.

Anti Bacterial property: Nano silver Titanium dioxide and nano Zinc oxide are found to impart sterilizing effect with anti bacterial property. Nano silver particles with large surface area improve their contact with bacteria or fungi, inhibit cell growth by affecting the cellular metabolism and thus act as effective bactericide or fungicide. Nano silver particle is used in socks and other health care products such as dressings for burns and skin donor, etc. Nano Zinc oxide can also be used as a good photocatalytic agent having anti bacterial property. Self cleaning suits make use of a film polymer of polyglycidylacrylate mixed with nano silver which has inherent property of imparting anti microbial or odor free effects.

Antistatic Properties: Synthetic fibres are notorious for development of static large and thus durable anti static finishes are required to be given to these fibres to enable processing of them free of problems. Nano size titanium dioxide, zinc oxide, viscous and nano antimony dioxide, tin dioxide have been found to provide anti static effect, as they are electrically conducting materials causing the effective decay of static charge.

UV Protection : Titanium dioxide, zinc oxide, silicon dioxide and aluminum dioxide are some of the semi conductors which are used as inorganic UV blockers and these materials in nano size are highly efficient in absorbing and scattering UV radiation. Due to the minute size of the particles, the lights scattering predominate at approximately 1/10 of the wave length of the scattered light and hence for UV radiation to be scattered in the 200-400 nano metre, optimum particle size required is about 20-40 nano metre. The UV blocking treatment for cotton fabric consists of forming a thin layer of titanium dioxide on the surface of the treated cotton fabric which in turn found to give a very high UPF.

Nano Finished Garments: In general the nano finished garments offer protection due to a coating which is water and beverage repellent. The naked eye cannot detect the protective layer due to the near about 100 nano meter size of finish on the clothing which is water and dirt resistant. A lot of saving on laundry time and cost can be obtained with good feel and breathability as well as resistance to wrinkles. The finish is non toxic in nature and bright and fresh looking. These are value added effects with environment friendly technology.

Functional textiles have opened a new vista of applications in diverse field of human life. Many of these applications are highly crucial and thus these materials with high end performance properties are going to play paramount role in the life of modern man. Surely in the fast developing economy like ours, the growth of such Textile Materials will take place at galloping rate. Not only will it act as the driving force for R&D activities, tapping hitherto untapped field of Functional Textiles and Apparels, it will also be a great booster to our economy and to the same extent it will slowly reduce India's dependence of imported Technologies in this field.
