Antibacterial and physicomechanical properties of cellulosic nonwovens functionalized with chitosan: a study on interaction effects of influencing factors and assessment methods.

ABSTRACT: The growing demand for antimicrobial textiles and environmental concerns over synthetic agents have driven interest in biobased agents like chitosan, an eco-friendly alternative reported with variable effectiveness on textiles. This research investigates the effects of chitosan's molecular weight, concentration, treatment method, and their interaction effects on the antibacterial and physicomechanical properties of cellulosic nonwovens. The role of culture medium dynamics in antibacterial testing was also examined. Chitosan with low (30 kDa), medium (250 kDa) and high (2100 kDa) molecular weights at concentrations of 1 to 15 g/L was applied using pad-dry and dip-dry methods, with dip coating resulting in higher chitosan deposition.
