Chitosan, derived mostly from the exoskeleton of crustaceans such as crabs, lobsters and shrimps, is a compound that can be processed to become yarn. Characterized by antibacterial and antimicrobic nature, the products made of Chitosan yarn restrain the growth of bacteria and the development of unwanted smell. In addition, it is biodegradable and highly biocompatible that means the products made out of it are comparatively environmentally-friendly and won’t cause irritation to most people.
