Abstract
The invention discloses a production method of non heat seal teabag paper. Final products can be obtained through a surface sizing process or a coating process in the existing production method of the non heat seal teabag paper, and a plurality of adhesives and additives are needed to add. The production method includes subjecting plant fibers to special processing, and reserving the length of fibers as far as possible during fully fibrillation; and adding appropriate thermosetting type reinforcing agent into the fiber after the special processing to obtain a body paper product through papermaking. The body paper product can be used directly without the surface sizing and the follow-up coating processing and can adapt to processing requirements for modern high-speed packing machines. According to the production method, the defect that final products can be obtained through the surface sizing or coating in the existing production method of the non heat seal teabag paper is overcome, the paper is formed once, the surface sizing or coating process is reduced, usage of chemical additives in the non heat seal teabag paper is reduced, obtained products are environment-friendly and good in processability, simultaneously, the production process is simplified, and the energy consumption and cost are reduced.
Description
Technical field
The present invention relates to a kind of manufacture method of non-heat-sealing tea filter paper, especially relate to the non-heat-sealing tea filter paper without the whole plant fiber of top sizing or coating.
Background technology
The manufacture method of traditional non-heat-sealing tea filter paper be fiber after the paper machine is manufactured paper with pulp moulding, make through top sizing or coating.The whole manufacture process link of this class manufacture method is more, and the chemical industry additive is many, and energy consumption is large.Along with the raising of people's quality of life, environmental protection, the health and safety requirement of product are also had higher requirement.The use that reduces as much as possible chemical products is this manufacture method main purpose, and the while owing to do not need top sizing or painting process, is obviously reduced energy consumption in this manufacture method.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome the defectives such as existing non-heat-sealing tea filter paper is more through the manufacture process link of top sizing or coating, the chemical industry additive is many, energy consumption is large, provides that a kind of manufacture process is simple, healthy and safe, low energy consumption, the manufacture method of non-heat-sealing tea filter paper cheaply.
For achieving the above object, the manufacture method of non-heat-sealing tea filter paper of the present invention is characterized in that: by the combined treatment to fiber, keep fibre length when reaching abundant wire-dividing broom purification; In slurry, add an amount of reinforcing agent, water-soluble macromolecular material, obtain former paper product through manufacturing paper with pulp; Former paper product is not done top sizing, coating is processed and directly used.
As the optimization technique means, described combined treatment to fiber refers to the string that contains chemical wood pulp is processed by the mill of beater, deflaker, different abrasive discs successively, obtains 35-45
OKeep fibre length in the time of the SR beating degree.Further, described string, reinforcing agent, water-soluble macromolecular material become the mass percent in the paper to be respectively 98.0-99.9%, 0.05%-1.5%, 0.05-0.5% at body paper, and the mass percent sum of described each component is 100%.Described string is at least a in cotton pulp fiber, wood pulp fibre, the bast fiber.Concrete, described cotton pulp fiber is chemical cotton pulp.Described wood pulp fibre is that leaf wood is or/and the chemical pulp of needlebush perhaps is that leaf wood is or/and the CTMP of needlebush.Described bast fiber is at least a in mulberry root bark pulp, manila pulp, sisal fiber, the tossa fiber.
As the optimization technique means, described reinforcing agent is the thermosetting reinforcing agent.
As the optimization technique means, the finished product body paper that obtains manufacturing paper with pulp batches after cutting and becomes into paper.
The invention has the beneficial effects as follows: by the multiple processing mode combination to string, reach the abundant wire-dividing broom purification of fiber, keep as far as possible fibre length simultaneously, guarantee to greatest extent interfibrous adhesion, reach product to the requirement of dry strength.Add again heat curing-type reinforcing agent and the water-soluble macromolecular material of 0.1%-2.0% in the fiber after processing, give product certain wet strength.
Non-heat-sealing tea filter paper manufacture method process of the present invention is simple, does not need through top sizing or be coated with to obtain qualified products, and energy resource consumption is low, and product cost is low.And adopt natural string, heat curing-type reinforcing agent, water-soluble macromolecular material so that the non-heat-sealing tea filter paper of making has higher dried, wet strength, good water permeability, become paper soft, good processability can adapt to the processing request of Modern High-Speed packing machine.
The non-heat-sealing tea filter paper that the inventive method makes does not contain harmful chemical addition agent, is the non-heat-sealing tea filter paper of environment-friendly type product.
The specific embodiment
