| titleOfInvention | Method for preparing cigarette tipping paper by using waste tobacco stems |
| abstract | The invention provides a method for preparing cigarette tipping paper by using waste tobacco stems. The tipping paper takes tobacco stems as raw materials, and is subjected to wet-process pith removal to remove hemicellulose, and then slicing treatment; then, the fermentation liquor and the tobacco stem fibers are collected after the processes of pre-thread rolling treatment and microecological regulation and modification treatment of the pulp are sequentially carried out, the tobacco stem fibers are subjected to high-concentration pulping and latency elimination treatment, an upflow type pressure screen is adopted for classification to obtain tobacco stem papermaking pulp, and the papermaking is carried out to obtain the paper with the quantitative ratio of 30-50 g/m 2 Adding amino acid, reducing sugar and an auxiliary agent into fermentation liquor to react and then concentrating to obtain a coating liquid, and coating the coating liquid on the paper base to prepare the tipping paper for the cigarette. The tipping paper can be directly used, so that the tobacco material is promoted to develop towards the directions of green, environmental protection, sanitation, safety and resource utilization, and the tipping paper also has the functions of decoration and anti-counterfeiting. |
