Abstract
In the present investigation cellulose nano whisker is separated from industrial waste viscose rayon fibre, characterized by SEM images and FTIR spectroscopy. The size and size distribution of these nano crystals have also been examined using particle size analyzer; the average size of the particles is found to be 348 nm. The findings support the size and shape of the synthesized nano cellulose particles. These nanoparticles have been applied to polyester fabric by padding technique and manifested the improved physical and thermal properties. The dyeing behaviour of the treated fabrics with direct dye has also been studied and the build-up of dyes, measured as colour strength in terms of K/S values, reported. The higher K/S values are obtained when the cellulose nano is anchored in the fibre matrix, i.e. when the fibre is pre-treated and dyed with direct dyes. Improved colour strength with good resistance towards soaping is obtained after treatment of fabrics with nano cellulose.

Summary
Textile materials made from natural fibers have played an important role in the life of human beings from time immemorial and still are widely used in the modern textiles industry for their unique properties as high quality textile materials. Due to the variation in staple length, the natural fibers with short staple length can’t be used to spin yarns. Fine/super fine powder prepared from protein or cellulose fiber is generally known as nano-whiskers, which can impart various functional properties to the textiles and contribute significantly in the field of electronics and medicines. Many researchers have reported new method of synthesis nano-whiskers and their application in bio-technological and bio-medical fields [4-7]. Nano scale cellulose polymers were prepared from viscose rayon yarns by a novel technique. The prepared cellulose nano whiskers were characterized for their size, shape and chemical composition. Nano scale cellulose was applied to polyester textiles by padding technique. The fabrics was cleaned with 2% sodium carbonate and 5% nonionic detergent at 70°C temperature for 15 minute again washed and neutralized before used
