Biopolymer chitosan: Properties, interactions and its use in the treatment of textiles

The biopolymer chitosan is obtained by the deacetylation of chitin, the second most abundant polysaccharide in nature, after cellulose. It is becoming an increasingly important biopolymer because it offers unique physico-chemical and biological properties. Due to its solubility, chitosan allows processing from aqueous solutions. This review provides information on important chitosan properties, as well as on some interactions that are of special interest for chitosan application. It summarizes some of the most important developments in the use of chitosan in the treatment of textile materials. Special emphasis is given to improved dyeing properties of the textile material treated with chitosan.
