一种添加含氟憎水憎油剂的低吸附效率卷烟滤嘴及该含氟憎水憎油剂的应用
摘要：
一种添加含氟憎水憎油剂的低吸附效率卷烟滤嘴及该含氟憎水憎油剂的应用。所述的滤嘴中添加含氟憎水憎油剂；所述的含氟憎水憎油剂为全氟烷基磺酸类或全氟烷基烷氧基硅烷类或它们的混合物。这种滤嘴在醋酸纤维表面涂布含氟憎水憎油剂，具有较低的焦油吸附效率，可以有效降低一氧化碳/焦油比。滤嘴成型后含氟憎水憎油剂占滤嘴纤维的重量比为0.5～2.0‰。
摘要（英）：

The invention relates to a cigarette filter which has the low absorption efficiency and is added by fluorine-containing hydrophobic and oleophobic agent and the application of the fluorine-containing hydrophobic and oleophobic agent. The filter is added by fluorine-containing hydrophobic and oleophobic agent; the fluorine-containing hydrophobic and oleophobic agent is perfluoroalkyl sulfonate or perfluoroalkyl alkyloxy silane or the mixture of the two. The filter is coated by the fluorine-containing hydrophobic and oleophobic agent on the cellulose acetate surface, and the invention has lowertar absorption efficiency and can effectively reduce the ratio of carbon monoxide/tar. The weight ratio of the fluorine-containing hydrophobic and oleophobic agent in the filter fiber after the filter forming is 0.5 to 2.0 per mille.
