Outline of Final Research Achievements

The potential of cellulose nanofibers (CNF) as coating materials on fabrics was assessed by detailed characterization of several CNF-coated cellulosic fabrics. CNF-coated fabrics became smooth and stiff, their texture has greatly changed. CNF coating increased the resistance to air permeability of the fabrics, which leads to excellent filtering characteristics. The heat retention properties were improved after CNF coating of the fabrics. The hygroscopic property and water absorbency also changed depending on the fabrics. In the case of ink-jet printing on CNF-coated fabrics, the ink pigments were retained within the CNF layer improving the color density. The CNF-coated fabrics could be used in several applications that need air-barrier and heat retention properties, such as disposable clothing, curtains, and wallpaper.
