目的 建立烟用内衬纸关键性指标的专用检测方法，初步分析相关指标的影响因素，为其具体应用提供理论依据。方法 采用相应的研究方法及国家标准对烟用内衬纸的部分关键性指标(透湿性和成型度)及微观特性指标(厚度、纸张表面pH值和纤维组成)进行检测，并进一步分析相应微观特性指标对关键性指标的影响。结果 采用研究方法测定不同类型烟用内衬纸的透湿性和成型度，发现复合内衬纸的透湿量和成型度均较低，透湿量为0.554 4~2.046 g/(m².24 h)，成型度为22°~26°，转移镀铝内衬纸和无铝内衬纸的透湿性和成型度相差不大;内衬纸的微观特性对样品的成型度有一定影响，一般随着厚度的增加内衬纸的成型度随之增加，阔叶木浆用量增加，成型度有降低的趋势。结论 建立烟用内衬纸透湿性和成型度的有效检测方法，分析微观特性参数对宏观特性的影响，具有一定的理论和应用价值。

The work aims to establish a special detection method for key indicators of tobacco lining paper, and primarily analyze the affecting factors of related indicators, to provide theoretical basis for their specific application. The corresponding research methods and national standards were used to detect some key indicators (moisture permeability and formability) and microscopic characteristic indicators (thickness, paper surface pH value, and fiber composition) of tobacco lining paper. Further, the effect of corresponding microscopic characteristic indicators on key indicators was analyzed. The moisture permeability and formability of different types of tobacco lining paper were measured by research methods. It was found that the moisture permeability and formability of composite inner lining papers were low, which were 0.554 4-2.046 g/(m2.24 h) and 22°-26°, respectively, and the moisture permeability and formability of transfer aluminum plated inner lining paper and aluminum free inner lining paper were not significantly different. The microscopic characteristics of the inner lining paper had a certain impact on the formability of the sample. Generally, with the increasing of thickness, the formability of the inner lining paper also increased. As the dosage of broad-leaved wood pulp increased, the formability tended to decrease. An effective detection method of moisture permeability and formability of tobacco lining paper was established and the impact of microscopic characteristic parameters on macroscopic characteristics is analyzed, which has certain theoretical and application value.
