技术领域 technical field
本发明涉及卷烟制造领域，尤其涉及一种具有X型截面的降焦卷烟滤棒用混合单旦丝束及其制备方法和应用。 The invention relates to the field of cigarette manufacturing, in particular to a mixed single-denier tow with an X-shaped cross section for a reduced-focus cigarette filter rod, a preparation method and application thereof.
背景技术 Background technique
随着消费者对吸烟与健康问题的日益关注，烟草行业降焦减害工作取得了一定的进步，卷烟焦油量从02年的17mg降至目前的11mg，到2015年，国家烟草专卖局要求卷烟盒标焦油量不超过10mg，危害性指数不得超过9，这又对烟草行业提出了新的挑战。目前国内销售的低焦油卷烟基本上都通过复合滤棒、纸质滤棒等异型滤棒配合以卷烟打孔进行降焦。 As consumers pay more and more attention to smoking and health issues, the tobacco industry has made some progress in tar reduction and harm reduction. The tar content of cigarettes has dropped from 17mg in 2002 to the current 11mg. By 2015, the State Tobacco Monopoly Administration requires that cigarettes The amount of tar on the box label shall not exceed 10mg, and the hazard index shall not exceed 9, which poses new challenges to the tobacco industry. At present, the low-tar cigarettes sold in the country are basically reduced by punching holes in cigarettes through special-shaped filter rods such as composite filter rods and paper filter rods.
