Example Embodiment

[0043] Example 1

[0044] The long and short wood fibers are used as the main skeleton of the substrate in the longitudinal and vertical directions, the high-efficiency defibrated tobacco stems are used as the auxiliary skeleton of the horizontal plane of the substrate, and the fine pulped tobacco pieces are used as the filler of the substrate to form To ensure the normal operation of the paper machine, the paper-making method with good bulk and high coating rate can reconstitute tobacco leaves. The schematic diagram of the distribution state of long and short fibers in the water filtration process of the substrate is as follows: figure 1 Shown.

[0045] Tobacco stems and tobacco flakes are extracted in a "half split and half combined" method. Specifically, the tobacco stems are first extracted with hot water alone for 30 minutes, the extraction temperature is 60°C, and the solid-liquid ratio is 1:3; the rodent-shaped defibrator is used for defibrillation, the mass volume concentr...

Abstract

The invention belongs to the special papermaking production field, and specifically relates to a high-bulk papermaking method reconstruction tobacco leaf fiber composition and a preparation method and application; the reconstruction tobacco leaf comprises a tobacco raw material, wood long fibers and wood short fibers, and is prepared by mixing said compositions; the short fibers are arranged in a Z-type in a water filtering process, thus effectively improving the bulk property and spreading rate while fully ensuring the substrate tensile strength and paper machine operationability, improving filling material retention rate and product yield, reducing production cost, improving product fully combustion level, and reducing CO release amount.

Description

technical field [0001] The invention belongs to the field of special paper production, and in particular relates to a high-bulk papermaking method reconstituted tobacco leaf and its preparation and application. Background technique [0002] As a substitute for natural tobacco leaves, papermaking reconstituted tobacco leaves need to approximate the physical quality and shape of natural tobacco leaves, that is, the surface is curly and soft, and the structure is thick and strong. Due to the irregular fiber structure of a single tobacco raw material, it is impossible to make a finished sheet on a paper machine. It is necessary to add a certain amount of additional fiber to improve the physical quality and copyability of the product. If the added fiber structure is short and thin, the bulk of the product can be fully guaranteed, but the tensile strength of the product is limited, the running stability of the paper machine is poor, and the frequency of paper breakage increases; ...
