  • Patent number: 9587352
    Abstract: A textile and a dye manufactured from fibers that are derived from tobacco plants and a process for making the textile and dye from the tobacco plants. In a preferred embodiment, the tobacco is organically grown and the entire tobacco plant, including stem and leaves, is utilized to produce the tobacco plant fiber used for making a textile and a natural dye utilized to color the textile or other textiles. One or more secondary material fibers can be mixed with the tobacco plant fiber to produce the textile. The process percolates a hot liquid solution onto tobacco plant material to cause a chemical reaction with the tobacco plant material to produce the tobacco plant fiber. Preferably, the process is a closed-loop system that minimizes the impact on the environment and utilizes less material, fuel and other resources. The dye does not require a mordant to bind with the textile.

  • Patent number: 8007637
    Abstract: This invention relates to a production process of tobacco sheet by papermaking. The technical arrangement of this invention are: (a). to immerge and to extract tobacco stem and leaf scrap respectively by water-soluble solvents to respectively obtain solid tobacco stem and solid leaf scrap, and tobacco stem extract and leaf scrap extract via solid/liquid separation; (b). to defibrilate solid tobacco stem and solid leaf scrap respectively, to mix the obtained tobacco stem fiber and leaf scrap fiber and combined with dust to prepare fiber base; (c). to wholly or partly abnegate the tobacco stem extract obtained by Step (a), and to evaporated and to concentrate other extracts that then are sprayed or immerged to coat the formed fiber base that is then dried, threshed and shaped. The tobacco sheet production process offered by this invention has improved the tobacco sheet's filling capacity and its sensory quality.
