Chitosan microcapsules: Methods of the production and use in the textile finishing

Biopolymeric chitosan is considered a promising encapsulating agent for textile applications due to its biocompatibility, lack of toxicity, antibacterial activity, high availability, and low cost. After cellulose, it nature's most important organic compound. Also, has unique chemical properties cationic charge in solution. Microencapsulation technologies play an role protecting the trapped material durability effect, controlling release rate. The application microcapsules textiles follows current interest industries functionalization that give different products, such as aroma finish, insect repellency, antimicrobial thermal comfort. In this sense, methods coacervation, ionic gelation, LBL are presented production chitosan-based finishing incorporate them presented, bath exhaustion, filling, dry drying cure, spraying, immersion, grafting chemical. Finally, trends market identified guidance on future developments.
