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

Abstract

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.

Biopolimer hitozan se dobija deacetilovanjem hitina, polisaharida koji je drugi po rasprostranjenosti u prirodi, odmah posle celuloze. Hitozan danas dobija sve više na značaju kako zbog svojih jedinstvenih fizičko-hemijskih i bioloških svojstava, tako i zbog toga što je obrada ovim polimerom moguća iz vodenog rastvora. Ovaj pregled daje osvrt na važna svojstva hitozana i vrste interakcija koje su od posebnog interesa za primenu hitozana, kao i podatke o najvažnijim dostignućima u oblasti upotrebe hitozana u obradi tekstilnog materijala. Posebna pažnja je posvećena poboljšanim svojstvima bojenja tekstilnog materijala obrađenog hitozanom.
