▎ 摘　　要

NOVELTY - A cigarette filter material comprises tow set containing filaments comprising 60-95 wt.% non-crystalline polylactic acid, 5-40 wt.% crystalline polylactic acid and 0.1-3 wt.% nanomaterial. The nanomaterial is one of graphene oxide, carbon nanotubes and nano zinc oxide. USE - Cigarette filter material. ADVANTAGE - The filter material has low suction resistance and high filtration due to use of biodegradable polylactic acid material and has excellent processing performance compared to existing melt spinning processing method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of cigarette filter material.
