Embodiment 1
[0024] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . Gained tobacco stems and tobacco leaf fragment fibers are added with added fiber (8%, weight ratio) after defibration, and dry soot (particle diameter 20 mesh) is added through a designed ash adding device at the headflow pipeline process point from the stabilizer box to the headbox. -60 mesh) is made into a fiber sheet base sheet by paper machine, and the ratio is 20% (weight ratio). The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.

Embodiment 2
[0029] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . The resulting tobacco stems and tobacco leaf fragments are added with defibrated additional fibers (8%, weight ratio), and 30% (weight ratio) of dry soot (particle size 20 mesh-60 mesh) is added to the finished pulp tank and made by paper machine Fiber sheet substrate. The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.
[0030] According to the appearance inspection, the sheet structure is loose and the front surface is uneven.
[0031] Filling capacity detection, the filling value is 8.45m 3 / g.

Embodiment 3
[0034] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . Gained tobacco stems and tobacco leaf fragment fibers are added to the added fiber (8%, weight ratio) after the defibration, and are added to the filter net of a paper machine through a special soot adding device at the head box (headbox) to the first section of the paper machine vacuum floating roller. % (weight ratio) dry soot (particle diameter 50-80 mesh) is evenly sprayed on the wet slurry on the net, and is made into a fiber sheet substrate through paper machine. The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.
