摘要:为分析不同种类阔叶木浆纤维形态的特点和对卷烟纸物理指标的影响，本研究对11种阔叶木浆（7种桉木浆，3种桦木浆，1种杨木浆）进行纤维形态观察和测量、抄纸以及生产验证。结果表明，纤维的长宽比、湿重、打浆度以及纸张紧度对卷烟纸透气性影响较大；杨木浆卷烟纸的罗纹强度最好（为23.5%），桦木浆次之、桉木浆最差；杨木浆适用于生产高定量、高透气度卷烟纸，南美1号桉木浆、南欧桉木浆、南美2号桉木浆适用于生产低定量、高透气度或高定量、高透气度卷烟纸；南美3号桉木浆和云南桉木浆适用于生产低定量、低透气度卷烟纸；11种阔叶木浆均可生产高定量、低透气度卷烟纸。

Abstract:In order to study the effect of different kinds of hardwood pulp on the physical index of cigarette paper and the characteristics of its fiber morphology， 11 kinds of hardwood pulp were observed and measured， the paper making and production verification were carried out. The results showed that the air permeability of the paper was greatly affected by fibre length-width ratio， wet weight， beating degree and paper density. The spiral marking intensity of Poplar pulp cigarette paper was 23.5%，which was the best . Northern European poplar pulp was suitable for the production of cigarette paper with high basis weight and high-permeability. Southern American No.1 eucalyptus pulp， Southern European eucalyptus pulp， and Southern American No.2 eucalyptus pulp were suitable for the production of cigarette paper with low basis weight， high-permeability or highbasis weight and high-permeability. Southern American No.3 eucalyptus pulp and Yunnan eucalyptus pulp were suitable for the production of low basis weight and low air permeability cigarette paper. The above 11 kinds of hardwood pulp could produce high basis weight and low air permeability cigarette paper.
