Chitosan and Its Derivatives in The Functional Processing Of Textiles

Abstract

chitosan, a natural polysaccharide, has received great attention for use in textile applications Because of its exceptional features, including as biodegradability, biocompatibility, haemostasis, antibacterial activity, and other intrinsic functional properties, has gained a lot of attention for usage in textile applications. Chitosan has piqued the curiosity of both scientists and industry. Many researchers have attempted to create new biomaterials based on chitosan derivatives through chemical changes, particularly sulfonation or sulfation processes, in order to modify the physical and biological properties throughout the past decades. Because of the existence of residual amino groups, the resulting numerous derivatives exhibit appropriate biological features such as antioxidant and antiviral activity, which broadens their spectrum of applicability. This study provides an overview of chitosan, techniques for producing it, and strategies for chemically modifying chitosan by adding groups on its backbone, as well as applications in the realm of functional textiles.
