This study explores the development of cotton fabrics with enhanced color durability and controlled fragrance release through the microencapsulation of lavender oil using chitosan and carboxymethyl cellulose (CMC) in combination with anthocyanin-based dyeing....Microcapsules were prepared by emulsifying lavender oil in a solution containing anthocyanin and chitosan followed by their incorporation into a CMC solution to yield stable capsules....The structural integrity of the microcapsules was analyzed by optical microscopy, and their interaction was confirmed via FTIR analysis, which revealed strong hydrogen bonding and electrostatic interactions between chitosan and CMC....These results highlight the potential of biopolymers such as chitosan and CMC in dyeing and encapsulation processes, offering sustainable methods for the development of multifunctional and eco-friendly textiles.

Hyaluronic acid and hydroxypropyl chitosan are the main bodies of cryogel, and dopamine is grafted onto the side chain of hyaluronic acid through a one pot method to cope with oxidative stress and shorten the process flow....Quaternary chitosan is intercalated into the polymer network and provides abundant positive charges. Cryogel shows high positive electricity in acidic environment (17.10 mV, pH = 5.0), which benefits cryogel to adsorb red blood cells and platelets and to resist bacterial infection.
