Preparation and performance of chitosan/viscose spun-laced nonwoven

To develop a new generation of antibacterial biomedical material,a novel spun-laced nonwoven fabric was prepared from chitosan and viscose fiber mixture.A comparative analysis was conducted of the spun-laced nonwoven fabrics with different areal densities and proportions with respect to the mechanical properties,soft,absorbent,breathable and antibacterial properties.It shows that the chitosan/viscose spunlaced nonwoven has a good biomedical performance,and its breaking strength increases with the increase of areal density,while softness,absorbency and air permeability exhibit downward trend;at the same time,the spun-laced nonwoven with greater content of chitosan fiber has better softness,good absorbency,air permeability and significantly improved antibacterial effect,but the strength slightly declines.
