Fabricating multifunctional nanoparticles bonded to enzymatically oxidized fabrics for their various applications

Abstract

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