Tobacco stalk fiber substance as well as preparation method and application thereof

Abstract

The invention provides a tobacco stalk fiber substance as well as a preparation method and an application thereof. The tobacco stalk fiber substance is obtained by the way that tobacco stalk is taken as a main raw material and biological degumming and extraction are carried out, the tobacco stalk fiber substance mainly comprises a single tobacco stalk fiber and a tobacco stalk fiber bundle (containing 2-20 single tobacco stalk fibers), and the average length of the fibers is 3-30mm. Production steps comprise processes such as burdening, biological degumming, defibering, fiber extracting and the like. The preparation method provided by the invention has the advantages of low degree of disruption to the fiber, high defibering degree, high long fiber ratio, low requirement on strength of mechanical equipment, low energy consumption and water consumption and no pollution discharge. The prepared fiber can be widely applied to tobacco sheet processing, papermaking, preparation of substrate used for soilless culture and the like.

Description

Technical field [0001] The invention relates to the technical field of tobacco stem waste utilization and tobacco stem defibrillation, in particular to a tobacco stem fibrous material and a biological defibrillation method and application thereof. technical background [0002] Tobacco stems are the thick, hard veins of tobacco leaves, accounting for about 20-30% of the leaf weight. With the comprehensive promotion of the tobacco threshing and redrying process in my country, a large amount of tobacco stem waste is produced. The tobacco stem waste produced in my country’s tobacco processing reaches hundreds of thousands of tons each year. At present, part of the tobacco stem waste is used for the production of tobacco slices, and most of the waste is used for the production of tobacco slices. Can not be used effectively, resulting in a backlog of inventory, or use incineration, sanitary landfill and other methods to destroy, resulting in waste of resources. [0003] At present, in th...

Problems solved by technology

With the comprehensive promotion of tobacco threshing and rebaking process in my country, a large amount of tobacco stem waste is produced. The annual tobacco stem waste produced in my country's tobacco processing reaches hundreds of thousands of tons. At present, part of the tobacco stem waste is used for the production of tobacco sheets, and most of it is due to Cannot be effectively used, resulting in a backlog of inventory, or destroyed by incineration, sanitary landfill, etc., resulting in waste of resources

[0003] At present, in the process of producing tobacco sheet from tobacco stem waste, mechanical fiberizing and beating methods are mainly used to prepare fiber raw materials. During the process of mechanical fiberizing and beating, the fiber structure of tobacco stems is greatly damaged, especially the fibers are easily broken. The proportion of short fibers is high, resulting in dense structure of thin slice products, poor filling and burning properties, and unsatisfactory coke reduction effect

[0004] On the other hand, in the pulping and papermaking process of using tobacco waste, there are currently two main methods. One is to directly adopt mechanical defibration and pulping. Great destructive effect, especially easy to break fibers, high proportion of short fibers, resulting in dense structure of paper or cardboard products, poor elasticity, large specificity, residual pectin is easy to cause mildew during product use, and poor durability

The second is to adopt the traditional chemical fiberizing and pulping method, which consumes a lot of energy, causes serious pollution, and the fibers are easy to cause damage.
