摘要
为给细支卷烟(圆周=17.0 mm)吸阻设计及优化提供参考,将5种规格二醋酸纤维丝束(8.0Y/15 000、9.5Y/12 000、11.0Y/15 000、6.0Y/17 000、6.7Y/17 000)成型为不同压降(2 400～5 200 Pa)滤棒,并搭配不同滤嘴通风率(0、20%、40%、60%)进行细支卷烟样品制备,考察了滤嘴通风率、二醋酸纤维丝束规格及滤棒压降对细支卷烟吸阻的影响。结果表明:(1)固定滤棒压降,烟支吸阻与滤嘴通风率呈显著负相关关系(R^2>0.98),且滤棒压降增大,改变相同滤嘴通风率对烟支吸阻的影响幅度略有增加;(2)固定滤嘴通风率,高单旦、低总旦规格二醋酸纤维丝束适宜于降低烟支吸阻;(3)固定滤嘴通风率,烟支吸阻与滤棒压降呈显著正相关关系(R^2>0.96),且滤嘴通风率增大,改变相同滤棒压降对烟支吸阻的影响幅度减弱。
In order to provide references for the design and optimization of draw resistance of slim cigarette,cigarette samples of 17.0 mm circumference were prepared with filter rods made of cellulose acetate tow of five tow items(8.0Y/15000, 9.5Y/12000, 11.0Y/15000, 6.0Y/17000, 6.7Y/17000)with pressure drop from2400 to 5200 Pa, and cigarettes’ ventilation rates were 0, 20%, 40%, 60% separately. The effects of ventilation rate, pressure drop of filter and cellulose acetate tow item on the draw resistance of cigarette were investigated. The results showed that: 1)The ventilation rate was significantly negatively correlated(R^2> 0.98)with the draw resistance of cigarette at the same pressure drop of filter rods, and the influencing degree raised slightly with the increase of pressure drop of filter rod. 2)At the same filter ventilation rate, the acetate tow with high denier per filament(dpf) and low total denier reduced the draw resistance of cigarette. 3) The pressure drop of filter rod significantly positively correlated to the draw resistance of cigarette(R^2>0.96)at the same filter ventilation rate, and the influencing degree decreased with the increase of filter ventilation rate.
