In this study, an eco-friendly mask pack sheet system with enhanced water absorption as well as improved physical properties, while providing a soft feel, was established through a bar-coating-based fiber finishing method. For this purpose aqueous solution containing carboxymethyl cellulose nanofibrils(c-CNF) was bar-coated onto cotton non-woven fabrics(COF), followed by drying to generate a sheet form. As a result, the c-CNF/COF exhibited enhanced tensile strength, water absorption, and coefficient of friction coefficient. We observed the increase in weight proportional to the amount of the coated c-CNF, whereas the thickness decreased due to compression during the bar-coating. Despite the formation of a non-porous structure, the addition of c-CNF led to substantial improvement in water absorption capacity. Furthermore, the c-CNF/COF showed longer drying times, a reduced friction coefficient, and enhanced mechanical properties. Cytotoxicity evaluation confirmed the biocompatibility of the c-CNF/COF. This study underscores the feasibility of utilizing the c-CNF to produce non-woven fabrics for the development of eco-friendly mask-pack sheets, which allows us to explore potential applications in the cosmetics industry.
