Description

Functional paper and the paper manufacturing method using natural dyes {Ability paper and the paper manufacture method that use nature dye}

The present invention relates to a functional paper material containing appropriate natural dyes such as ocher and vegetable salts, and a method of manufacturing the same. When the paper product is made and used in this way, the antibacterial, far-infrared, and ultraviolet rays are absorbed by the natural dyes contained in the paper. It aims to enjoy various effects such as effect, warm and moisturizing, deodorization, sterilization, and air purification.

As is well known, paper is a necessity that is always in contact with and use in modern life. However, the existing paper materials have been used for simple original purposes such as packaging, writing, hygiene, building interior, etc. due to the nature of the material, and it would be difficult to add other functions other than the above-mentioned purpose.

In recent years, paper such as wallpaper containing clay or charcoal is being developed, but these are only coatings to form a fine layer on the surface of the paper, so that the functions of such materials do not last long. However, the degree of inclusion was also insufficient, and it was insufficient to fully enjoy the effect of the added ingredients.

In addition, according to the conventional method of containing the ocher component, since it contains a large amount of harmful chemicals and was unable to efficiently remove many bacteria and heavy metals contained in the ocher, it not only loses its own function but also becomes harmful to the human body. There was.

The present invention devised in view of the above problems is effective in the process of papermaking using recycled phage or raw material pulp, so that the inside of the thickness of the paper material is sufficient and evenly contained in the ocher component can achieve a variety of very excellent loess effect In addition, it is a technical task to add a natural vegetable dye to obtain a distinctive and unique color of our own.

Hereinafter, the manufacturing method according to the present invention and the paper material according to the method will be described in detail.

Looking at the method of the present invention,

1st process

Paper material is prepared by pulverizing pulp, paper for recycling, or a mixture of pulp and paper.

2nd process

The paper material prepared above is prepared in 5% by weight and finely pulverized again in the second while mixing 95% of water thereto.

3rd process

5% to 100% of natural ocher salt and an appropriate amount of electrodeposition agent are mixed and mixed with respect to the weight of the paper material.

4th process

The nozzle is sprayed onto the tray to give the shape of a thin paper material.

5th process

Dehydration, drying and rolling complete the manufacture of the paper material.

The natural ocher salt added in the above process uses a cationic activator (cation) during the precipitation process, so that the pure ocher particles having negative (-) charges meet the cationic activator and float and remove impurities.

In addition, by selectively adding the vegetable dye during the addition of the yellow soil dye, it is possible to obtain a unique color of each vegetable salt solution.

Vegetable saline solution is pulverized plant material and put into water at 80 degrees to 90 degrees to be aged for 1 hour or more.

The types of vegetable saline are selectively used to obtain colors such as mugwort, persimmon, gardenia, onion, ginkgo biloba.

After manufacturing the paper material by this method, the material can be used as a paper material for various purposes. For example, as a packaging material, it can be used as a packaging box for fruits or vegetables, foodstuffs or clothing articles. have. In this case, the antimicrobial and sterilization function, which can be called the ocher's own function, prevents the decay and prevents the propagation of various bacteria, and the product packaged by the far-infrared effect can maintain the freshness better.

In addition, when used as a building interior material such as wallpaper will be able to achieve a more comfortable and healthful environment for people, if used as a purification filter will have a biologically excellent effect by antibacterial and sterilization function.

In addition, the sanitary articles and disposables may also be used by using the paper material manufactured by the above method, and may be used as disposable articles or sanitary articles very faithful to its original purpose due to the far-infrared effect as described above.

Example

After shredding the mixture of pulp and paper, which is a paper stock, to prepare 500g of paper material,

Here, 9500g of water is mixed and finely crushed again in a second mill in a crusher, and again, 250g of natural ocher salt and an appropriate amount of electrodeposition agent are mixed and mixed.

By spraying on the tray using a nozzle to give the shape of a thin paper material, dehydration, drying and rolling to complete the manufacture of the paper material.

By using such a paper material through the secondary processing according to the purpose it could be manufactured as a decorative material such as packaging materials or disposable and sanitary ware or wallpaper.

Antimicrobial activity (Shake flask method [FC-TM-19] -2001) was measured using the above paper material.
