烟丝结构对烟丝填充值和卷接质量的影响

研究了不同结构烟丝的填充值和卷接质量的变化规律。结果表明：在试验范围内，整丝率与烟丝的填充值、卷烟单支质量呈现出显著的相关性，当烟丝的整丝率(质量分数)≥80％时，可使烟丝的填充值稳定提高、卷烟单支质量显著降低；碎丝率与卷烟单支质量、卷烟空头率呈现出显著的线性关系，烟丝碎丝率(质量分数)增大1％，卷烟单支质量增加0．0084g，卷烟空头率增大0．41％，利用该成果，在生产中采取相应的措施，可使烟丝的结构更加合理，卷接质量及稳定性得到显著提高。

Effect of the size proportion of cut tobacco on the filling power of cut tobacco and cigarette making quality

Variation trend of the filling power and cigarette quality of cut tobacco was studied through altering size proportion of the same batch cut tobacco. Within the trial stretch experimental results showed that: when particles in cut tobacco are above 80%, the filling power of cut tobacco is higher and the cigarette weight is lighter;particles in cut tobacco have a significant correlation with the cigarette quality.When particles in cut tobacco increase 1%, the single cigarette weight increases 0.0084 g and the cigarette loose-ends ratio (increases) 0.41%. Series of measures were adopted to stablilize and improve size proportion of cut tobacco in Nanyang cigarette factory according to the conclusion.
