烟草薄片型卷烟纸的制备及性能研究

以烟梗为原料制取的化学机械浆(CMP)与少最木浆纤维配抄烟草薄片原纸,经烟草萃取液涂布后制备烟草薄片型卷烟纸,并检测其相关物理性能和感官品质.根据烟草薄片型卷烟纸对抗张强度、透气度等物理指标的要求,通过优化打浆工艺,确定其最佳打浆度为:烟梗化机浆35°SR;未漂针叶本浆80°SR;漂白阔叶木浆40°SR;漂白麻浆70°SR;烟梗化机浆、未漂针叶木浆、漂白阔叶木浆、漂白麻浆的最佳配比为:75∶20∶2.5∶2.5,在此条件下,其抗张指数、透气度和伸长率分别为39.7 N·m/g,10.21μm/(Pa·s)和1.41％；经评吸实验感官评价,与普通雪茄烟纸相比,烟草薄片型卷烟纸的木质杂气减少,刺激性降低,品质得到提升.

Cigarette Paper Based on Tobacco Sheet: Its Preparation and Properties

Tobacco stem was used to make pulp with chemimechanical pulping(CMP) process.The pulp was mixed with small amount of lignocellulosic fiber and used to make cigarette paper based on tobacco sheet.The obtained base paper was converted to be a cigarette paper by further coating with the extractives from tobacco stem.The physical properties and smoking quality of the paper were tested.According to the physics indexes(tensile strength,air permeability,etc.) requirement of cigarette paper and the optimization of beating experiment,the ratio of the materials and the optimal beating degree of the materials were as following: tobacco stem pulp 75%,35°SR;unbleached softwood 20%,80°SR;bleached hardwood 2.5%,40°SR;bleached cannabis 2.5%,70°SR.Under the condition,the tensile strength,air permeability and elongation of the cigarette paper were about 39.67 N · m/g,10.21 μm/(Pa · s) and 1.41 % respectively.Moreover,the results of smoking test of the cigarette paper based on tobacco sheet indicated that the woody odor and stimulation reduced,the quality was improved obviously compared with the normal cigarette paper.
