Description

Technical Field

[0001] The invention relates to the field of papermaking preparation, in particular to a papermaking preparation process of mugwort fiber derived from mugwort. Background Art

[0002] Pulp is a fibrous material made from plant fibers through different processing methods. The quality of pulp is mainly determined by its fiber morphology and fiber purity.

[0003] At present, the main raw materials for papermaking are divided into two categories: plant fiber raw materials and recycled fibers. Plant fiber raw materials include wood fiber (coniferous wood, hardwood), non-wood fiber and recycled fiber (regenerated fiber). Non-wood fiber refers to: 1. Grass fiber ① Straw: It is a common raw material for papermaking. The length of straw fiber is relatively short, generally between 0.9 and 1.5 mm, the cellulose content is about 35% to 40%, and the lignin content is about 12% to 15%. Due to its abundant resources and low cost, it is often used to make some medium and low-grade paper, such as toilet paper. However, straw fiber contains a lot of silicon components, and special treatment is required to remove silicon during the papermaking process, otherwise it will affect the quality of the paper.

[0004] ②Wheat straw: The fiber length is similar to that of rice straw, about 0.8-1.2mm, the cellulose content is about 37%-42%, and the lignin content is 13%-16%. It can also be used to produce household paper and cultural paper, which can reduce production costs to a certain extent.

[0005] 2. Bast fiber ① Hemp fiber: such as flax, ramie, etc. Hemp fiber is relatively long, flax fiber can reach 10-100mm in length, and ramie fiber is even longer, reaching 50-500mm. Its cellulose content is high, between 60%-80%, and its lignin content is low, about 2%-5%. Hemp fiber has high strength and good toughness, and can be used to make some special papers, such as banknote paper, bond paper, etc. These papers need to have high tensile strength and durability, and hemp fiber can meet these requirements.

[0006] ② Wormwood fiber: Wormwood seeds grow fast and are a sustainable raw material for papermaking. Wormwood fiber length is generally between 1.5 and 3.5 mm, with a cellulose content of about 40% to 50% and a lignin content of about 20% to 30%. Wormwood fiber can be used to produce paper with good strength and natural color, and is suitable for the production of various paper products such as packaging paper and household paper. For example, some environmentally friendly paper towel products use wormwood fiber as raw material, which is soft and tough.

[0007] With the rise of TCM health, moxibustion products are becoming more and more popular, but moxibustion products mainly use the leaves of mugwort. This has resulted in a large amount of waste of the neck of mugwort. Therefore, using mugwort stems to make paper not only reduces the use of wood, but also makes rational use of crops, while providing additional economic benefits for mugwort growers. The raw materials used for most existing papers are mostly wood pulp fibers. Due to the shortage of wood pulp in my country, most of the wood pulp raw materials currently need to rely on imports, so the price is high, the cost in production is high, and most of them are wet papermaking processes. The wet papermaking process is to boil the wood pulp at high temperature, drive it to the forming net by water flow, filter the pulp and squeeze and dehydrate it to form a paper tire, and then dry and calender it. This method has a complex production process, large equipment investment, and serious pollution; it consumes a lot of water, electricity, coal, chemical raw materials, and manpower, and the cost is relatively high.

[0008] There is also a dry papermaking method, but the existing dry papermaking method uses wood pulp board as raw material, which is costly, and the wood pulp is easy to agglomerate, and the production varieties are limited. It cannot solve the problem of reducing production costs and reducing dependence on imported raw materials in the papermaking process. Therefore, it is necessary to provide a wormwood fiber dry papermaking process. Summary of the invention
