Description

Functional paper and its preparation method

The present invention relates to a functional paper and a method for manufacturing the same, and more specifically, various effects can be expressed due to far-infrared rays generated from pulsarite by applying the fine pulsarite fine powder immobilized with the cypress extract to at least one side of the paper. In addition, the cypress extract (phytoncide) is able to obtain a stress reducing effect, is given strong antimicrobial, antifungal and antiviral properties, has an excellent deodorizing effect, avoids dust mites, harmless to the human body It relates to an environmentally friendly functional paper and a method of manufacturing the same.

In general, since the paper is subjected to a high temperature drying process of 120 ℃ or more, most of the microorganisms are killed in the paper immediately after the manufacture. However, as the produced paper passes through several users, many microorganisms inhabit the paper. In particular, books, banknotes, stamps, etc., which are exposed to various environments and exposed to various environments, are known to have a large number of microorganisms. Since various paper products pass through various environments, contamination by microorganisms is very serious. . In addition, there is a risk of discarding or losing preservation value in the case of books that are worth preserving as collections. In addition, in terms of recycling of resources due to environmental problems, the mixing rate of waste paper is increased in paper manufacturing. When waste paper collected from dirty environment is used during the papermaking process, microorganisms introduced from the waste paper or the atmosphere are multiplied in the papermaking process and slimes. The problem may arise.

Since most papers go through the surface treatment process, it is economical and effective to prevent the loss of drugs when the antimicrobial agent is administered to the surface treatment process. In addition, when preparing a coating solution for coating on paper, which is one of the surface treatment processes, a pigment and a binder are mixed. At this time, a latex, starch, carboxymethyl cellulose, etc. are used as a binder. Is a substance that is likely to rot and deteriorate easily by microorganisms. Therefore, when the antimicrobial agent is added to the coating solution, not only the preservation of the coating solution may be improved, but also the paper produced may have an advantage of being an antibacterial paper.

Many conventional methods for imparting antimicrobial properties to paper are known. For example, Japanese Patent No. 0607398 describes a method of manufacturing antibacterial paper by treating wood vineger with paper, and Japanese Patent No. 06055091 describes a method of adding fine particles pulverized bamboo during paper production. Japanese Patent No. 0615704 describes a method for preparing antimicrobial paper by adding a pigment containing a water-soluble phosphate, and Japanese Patent No. 05039397 describes a method of adding silver, copper, zinc or zinc compounds. Japanese Patent No. 05170608 discloses a method for preparing antimicrobial paint, paper, fiber, natural or synthetic rubber, etc. by adding 2-methyl-3-isothiazoline, bromic acid, iodic acid, periodic acid and the like. Japanese Patent No. 05186208 describes a method for producing aluminum phosphate by addition, and Japanese Patent No. 04144564 describes a carboxylic acid type polymer interface. Japanese Patent No. 02104798 describes a method for producing a plant wrapper or medical paper by adding ceramic powder to a paper, and Japanese Patent No. 02127596 describes chitin or chitosan on paper. Processes are disclosed for producing antimicrobial paper.

However, methods using inorganic antimicrobials impart stability to the paper by inhibiting the growth of microorganisms, but at the same time cause irritation to the skin of the human body, and also have the problem of potential as an environmental hormone and induction of resistant bacteria. .

In addition, although commercially available natural antimicrobial agents are widely used in recent years, they have a narrower antimicrobial spectrum than inorganic antimicrobials, and the antimicrobial active ingredients contained in plant extracts have very low physical and chemical stability against heat, light, and oxygen, compared to inorganic antimicrobials. In many cases, due to the limitation as a natural substance, most of them are not commercialized due to the problem that the antimicrobial active ingredient is decomposed during the distribution period and sufficient effects are not expressed.

On the other hand, in recent years, various functional products have been well received by consumers, and attempts have been made to give functionality even in paper products, but application examples are extremely insignificant.
