Abstract: An effective procedure for obtaining fragrance finished fabric based on cellulose and chitosan has been developed. The first step involves the formation of oxidized cellulose, which is able to form a schiff’s base with the chitosan. In order to maintain the strength of fabric, a novel enzymatic method for oxidation of cellulose is adopted. In the second step, chitosan nanoparticles loaded with the jasmine oil are prepared and coated on the oxidized cellulosic fabric by forming a strong covalent bond. The FTIR analysis proves the formation of cellulose-chitosan composite. Scanning electron microscopic study demonstrates the coating of nanoparticles on the cotton fabrics. The retention capacity of the jasmine oil in the fabric after repeated washings is proved by GC analysis. The cotton fabrics finished by the covalent bonded coating of chitosan nanoparticles loaded with the jasmine fragrance are found to have a better sustained release capability for a longer time as compared to the conventionally entrapped nanoparticles in the fabric.
