▎ 摘  要

NOVELTY - Preparing low-resistance easy-to-shape non-woven fabric comprises (i) mixing 30-50 pts. wt. polylactic acid, 5-8 pts. wt. succinylated chitosan/graphene oxide composite material, 20-45 pts. wt. polyimide, and 15-35 pts. wt. bamboo charcoal fiber to obtain material I, (ii) extruding and granulating the material I prepared in step (i) through a twin-screw extruder to obtain material II, (iii) drying the material II prepared in step (ii), heating, melting, extruding through a screw extruder, stretching, cooling, and self-bonding to form non-woven fabric, and (iv) spraying antistatic agent on the non-woven fabric preparing in step (iii), and drying to obtain final product. USE - The non-woven fabric is useful for medical masks (claimed). ADVANTAGE - The prepared non-woven fabric: has large specific surface area and excellent ductility, high antibacterial property, high filtration efficiency and low resistance; and can play role in preventing mildew.
