Chitosan is naturally antimicrobial because it has a cationically-charged structure. When applied as a surface treatment to textiles, such as cotton, chitosan is able to prevent growth of bacterial and fungal microorganisms [1]. Scientific research has shown that chitosan applied to clothing can maintain antimicrobial activity through 50 wash cycles [2]. Tidal Vision has developed proprietary cross-linking formulas that lead to greater durability in the bonding of chitosan to textile fibers.

By securely bonding chitosan to substrates or forming chitosan into films, Tidal Vision has developed novel techniques to incorporate chitosan into a variety of textiles. Our chitosan-based products can be sprayed, dipped, or composited with other materials to provide antimicrobial activity to textiles for a wide variety of applications.
