Problems solved by technology

[0004] People in the industry believe that the best raw material for "external fiber" is bleached coniferous wood fiber, while my country's wood and hemp as "external fiber" are constrained by factors such as planting area, growth cycle, ecological balance, production cost, and environmental protection. In addition, my country's forest resources are scarce, and the country attaches great importance to ecological protection, making it difficult for the domestic supply of wood fiber raw materials to meet the raw material needs of related industries for a long time in the future. Therefore, how to develop a new type of natural and regenerated cellulose fiber suitable for my country

Embodiment 1

[0045] (1) Cut the bamboo directly into lengths of 10-50mm and widths of 5-20mm, and use a dry method to remove impurities such as mud, sand, knots, and chips through a dust collector. After dust removal, send them to a cooking pot for alkaline cooking. The liquid ratio is 1 : 6, relative to the dry raw material quality, 30% (Na 2 O meter), 0.5% of dihydroanthraquinone, 0.1% of sodium dodecylbenzenesulfonate, 15% of sulfidation degree.

[0046] The cooking curve is: heat up to 150°C within 90 minutes, corresponding to a pressure in the pot of about 0.48MPa, then put the pot until the pressure in the pot is 0MPa, then raise the temperature to the highest temperature of 150°C, and keep it at this temperature for 80 minutes until the end of cooking.

[0047] (2) concentration: the slurry obtained in step (1) is put into the spray pot, and concentrated through waste liquid extraction, screening and concentrator, and the mass concentration of the slurry after concentration is 20%; ...

Embodiment 2

[0062] (1) Cut the bamboo directly into 10-50mm long and 5-20mm wide, adopt wet method, wash away surface impurities and remove excess water after the grass washer, enter the digester for alkaline cooking, the liquid ratio is 1: 3. Relative to the quality of the dry raw material, the amount of alkali used is 15% (calculated as Na2O), tetrahydroanthraquinone is 0.6%, xylenesulfonic acid is 0.2%, and the degree of sulfidation is 30%.

[0063] The cooking curve is: heat up to 148°C within 90 minutes, corresponding to a pressure of about 0.45MPa in the pot, then put the pot until the pressure in the pot is 0MPa, then raise the temperature to the highest temperature of 148°C, and keep it at this temperature for 80 minutes until the end of cooking.

[0064] (2) Concentration: the slurry obtained in step (1) is entered into the spray pot, and concentrated through waste liquid extraction, screening and concentrator, and the mass concentration of the slurry after concentration is 30%; ...

Embodiment 3

[0075] (1) Cut the bamboo directly into lengths of 10-50mm and widths of 5-20mm, and use a dry method to remove impurities such as mud, sand, knots, and chips through a dust collector. After dust removal, send them to a cooking pot for alkaline cooking. The liquid ratio is 1 : 4, relative to the dry raw material quality, 20% (Na 2 O meter), dihydrodihydroxyanthraquinone 1.0%, alkylphenol polyoxyethylene ether sodium sulfate 0.1%, degree of vulcanization 20%.

[0076] The cooking curve is: the temperature is raised to 152°C within 90 minutes, corresponding to a pressure in the pot of about 0.50 MPa, then the pot is placed until the pressure in the pot is 0 MPa, and then the temperature is raised to the highest temperature of 152°C, and kept at this temperature for 80 minutes until the end of cooking.

[0077] (2) Concentrate: the slurry that step (1) is obtained enters spray pot, is concentrated through waste liquid extraction, screening and concentrator, and the mass concentra...

Abstract

The invention belongs to the technical field of reconstituted tobacco, and specifically relates to natural-color bamboo pulp for a reconstituted tobacco additive and a preparation method thereof. The method is characterized in that bamboo is used as the raw material and subjected to preparing, stewing, squeezing extrusion, dipping, pulping and papermaking to obtain a high-purity product. The physical performance indexes of the natural-color bamboo pulp are that the tensile index is 35-45N-m/g; the burst index is 2.5-3.5kPa-m<2>/g; the tearing index is 6.5-9.5mN-m<2>/g; the intrinsic viscosity is 800-1000mL/g; the whiteness is 30-40% ISO; the pentosane is less than 8%; the ash content is less than 1.0%; the bulk is 5.0-8.5cm<3>/g. The prepared tobacco slices are added to finished cut tobacco based on ratio; the prepared cigarette is capable of supplying more air intake quantity while smoking, so that the cigarette can be promoted to completely burn, and the quantity of pyrolysis products under oxygen-poor condition can be effectively decreased, and as a result, the releasing quantity of harmful components such as tar and nicotine can be decreased.

Description

technical field [0001] The invention belongs to the technical field of paper-making reconstituted tobacco, and in particular relates to a method for preparing natural-color bamboo pulp for tobacco additives by using bamboo as a raw material, in particular to a natural-color bamboo pulp for reconstituted tobacco additives and a preparation method thereof. Background technique [0002] Reconstituted tobacco is tobacco sheet, which is used in cigarette formula in the form of an auxiliary material, which can reduce the consumption of tobacco leaves, reduce production costs, and effectively reduce the content of harmful components such as tar, nicotine, and CO emissions in cigarettes, and improve Cigarette safety, regulation of cigarette smoking and other functions. [0003] At present, the traditional paper-making tobacco sheet production process widely used in China is to use tobacco waste such as tobacco stems and tobacco chips as raw materials, extract and separate the water-...
