“…It allows its chemical modification by covalent attachment of various chemical groups, the association with anionic polymers forming polyelectrolyte complexes (PECs), and imparts good biological and mucoadhesive properties. 89 This chemical feature of CH is also responsible for its antimicrobial activity against a wide range of microorganisms, reported in several studies. The most accepted mechanism for this activity is based on the interaction of the positively charged CH with the negatively charged residues at the cell surface of microorganisms, alternating metabolism, and cell permeability.…”

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

“…In addition to the well-known applications for the production of a wound dressing, cell growth scaffolds, controlled-release drug carriers, hygiene products, or biodegradable packaging [ 1 , 2 , 3 , 5 , 6 , 7 ], there are original proposals for using this polysaccharide as flocculants in the treatment of drinking water [ 11 , 12 ], three dimensional-printed chitosan hydrogels for development of tissue engineering [ 13 ], as a valuable material for dentistry [ 14 ], targeted protein and gene delivery [ 15 ], or as photosensitizer carrier for Photodynamic Therapy (PDT) [ 16 ], material for refining fibers and fabrics (production of intelligent clothing) [ 17 ], in veterinary (e.g., in fish farming) [ 18 ], and as plant protection products [ 19 ]. Chitosan can be used in various physical forms (films, granules, microcapsules, gels, and aerogels), alone or in complex multi-component systems (as a matrix of other active ingredients, polymer blends, composites, and nanocomposites) [ 17 , 20 , 21 ].…”

Chitosan as a Protective Matrix for the Squaraine Dye

et al. 2021

Chitosan was used as a protective matrix for the photosensitive dye-squaraine (2,4-bis[4-(dimethylamino)phenyl]cyclobutane-1,3-diol). The physicochemical properties of the obtained systems, both in solution and in a solid-state, were investigated. However, it was found that diluted chitosan solutions with a few percent additions of dye show an intense fluorescence, which is suppressed in the solid-state. This is related to the morphology of the heterogeneous modified chitosan films. The important advantage of using a biopolymer matrix is the prevention of dye degradation under the influence of high energy ultraviolet (UV) radiation while the dye presence improves the chitosan heat resistance. It is caused by mutual interactions between macromolecules and dye. Owing to the protective action of chitosan, the dye release in liquid medium is limited. Chitosan solutions with a few percent additions of squaraine can be used in biomedical imaging thanks to the ability to emit light, while chitosan films can be protective coatings resistant to high temperatures and UV radiation.

By virtue of remarkable biocompatibility and their promising applications in biomedical fields, biomass‐regenerated fibers, such as wool keratin fiber and cellulose fiber, have attracted extensive attention. However, the insufficient mechanical performance still hinders their yarn manufacturing capability and further large‐scale applications. Herein, an ultra‐strong and ultra‐tough regenerated wool keratin fiber by regulating keratin conformation with high‐quality small‐size graphene (HQSGr) and mechanical training treatment (M‐HQSGr‐RWKF) is fabricated. With the assistance of mechanical training, a small addition of HQSGr (0.1 wt.%) remarkably augments the secondary structure transition from α‐helix to β‐sheet of the keratin, which delivers a tensile strength of 215.4 ± 5.2 MPa, surpassing all reported natural wool and regenerated wool or even poultry fibers. Benefiting from the excellent mechanical strength, wet‐state toughness (158.9 MJ m−3), and recoverable strain (205.0%), M‐HQSGr‐RWKF has been demonstrated as a biocompatible artificial muscle to drive the biomimetic motion, which manifests ultrahigh actuation strain greater than 100.0% and stress of 16.7 MPa. The derived ultra‐strong and ultra‐tough keratin fiber opens a new avenue for developing smart fiber from biomass resources.
