Description

[0001] The present invention relates to a method for manufacturing Korean paper containing a white flour tree,

The present invention relates to a method for producing Korean paper containing white flour and a paper making method using the same. More particularly, the present invention relates to a method for manufacturing Korean paper, which is improved in antibacterial and bactericidal effect by impregnating a fine wood powder with fine wood powder during the manufacture of Korean paper, and a paper made therefrom.

The main ingredient of Korean paper mulberry is mulberry (mulberry), which is obtained by processing the barked bark part of branches such as mulberry (mulberry), mountain mulberry (mulberry), mulberry mulberry and mountain mulberry Fiber). The bast fiber is robust, it is very soft in material, it is well ventilated, it can be manufactured by putting various patterns, it is not only easy to paint, but also absorbs oil well, so it is easy to manufacture.

In addition, since the pore of Korean paper acts as a filter, it is known that air purification ability and wood are breathable. Also, it has a function to absorb it when the humidity of the surroundings increases, and the light has the ability to reflect far away, Is known to have excellent long-term preservation capability.

On the other hand, since it is weak in water and it is long in the water, there is a lot of dust and a good ventilation, so there is little effect of winter in winter, and paints are well spread.

The cypress wood is cypress, cypress tree, and evergreen scaly leaf arbors belonging to the germination plant Cupressaceae. And, there is a large amount of substance called chiton feed in the raw wood. Phytoncide is known to be a substance that plants excrete and secrete to resist pathogens, insects and fungi.

Therefore, in the field of making eco-friendly products, the use of such phytoncide phytoncide is being actively carried out.

Korean Patent Laid-Open Publication No. 10-2011-0065837 discloses a mattress comprising a first fibrous body part spread out in a plate form, a crushed powder body part ground by a cotton milled wood and applied to one side of the first fibrous body part, A second fibrous body portion which is covered on one side face of the body portion and is formed by being spread out in a plate shape and a second lid portion which covers the entirety of the first fibrous body portion and the second fibrous body portion and is made of a cloth material, And a second mat portion formed so as to be brushed with a narrow width so as to be in contact with a side surface of the mattress portion. However, in the case of the above-mentioned patents, the present invention is not limited to a matrix in which a ground powder is simply ground, and the wood is not impregnated with wood.

Disclosed is a disposable cup prepared by extracting and mixing a white linseed liquid (phytoncide) in the above-mentioned registration chamber. However, the extraction and use of a white linseed liquid is complicated in the process and is inefficient .

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram showing high-functionality paper according to the present invention; Fig.
Figure 2 is a schematic plan view of the top paper layer.

The present invention can be all accomplished by the following description. The following description should be understood to describe preferred embodiments of the present invention, but the present invention is not necessarily limited thereto.

The present invention is directed to a method of making a high functionality Chinese paper comprising providing a lower paper layer, providing a top paper layer, and lapping them.

The paper that can be used as the lower paper layer may include both natural fibers and paper produced by chemical fibers.

The lower paper layer is preferably a white paper or paper paper, but known paper materials, for example, kraft paper. A court paper, a titanium paper, a paraffin paper, a paperboard, a lost paper paper, and a sulfur paper can be used.

The lower paper layer may have a weight of 70 to 150 g / m < 2 >.

The lower paper layer preferably has a thickness of 40 to 200 mu m. And most preferably 80 to 120 占 퐉. If the thickness is less than 40 탆, a space in which the protruding whitish powder protrudes from the back surface of the upper sheet is not secured. If the thickness is more than 200 탆, the flexibility of the finished paper is inferior.

The step of providing the top paper layer comprises the steps of putting the microcrystalline white powder into the fiber and pulp to prepare the mixture and papermaking the mixture.

The dodecaflower fiber is a fiber (bast fiber) obtained by processing a bark-covered bark part of a tree branch such as a mulberry tree, a mulberry tree, a mulberry tree mulberry and a mountain mulberry tree, Lt; / RTI >

 The core fiber having a length of 3 to 40 mm can be used. When the length of the core fiber is in the range of 3 to 40 mm, the effect of the operation is maximized.

Pulp is used for the upper paper layer, and known pulp may be used. For example, natural pulp such as flax, hemp, cottonwood, wood pulp, laminates, hemp, wool, and the like can be used, and rayon, acrylic, and polypropylene, polyethylene and polyvinyl chloride, polystyrene, Amide and the like may be used.

The pulp is preferably used in the form of a short fiber having a length of 3 mm or less. When the length of the pulp is 3 mm or less, it is advantageous in terms of the dusty fiber and the adsorption surface.

The fine textured powder may have a particle size (diameter) of 30 to 200 mesh. In the case of the above range, the plain wood powder can be easily impregnated between the pores of the paper.

The step of preparing the upper paper layer may be performed by first mixing the dough fiber and the pulp, adding the untwisted wood powder and the dung beetle to the dough paper and thoroughly kneading the dough paper and then pulverizing the proper amount of the paper in the paper machine.

In the step of producing the upper paper layer, 20 to 60 parts by weight of the pulp and 0.1 to 3 parts by weight of the fine textured powder may be mixed with 100 parts by weight of the fiber. The daphniae may be used in an amount of 0.0001 part by weight or less.

The upper paper layer may be manufactured in a paper machine, followed by washing and bleaching processes, followed by compression drying, and then a calender process to smoothen the surface of the paper.

The upper paper layer is laminated on the lower paper layer to produce a highly functional paper. For example, after applying the adhesive onto the top paper layer, the bottom paper layer may be laminated.

In another aspect, the present invention relates to high functionality Hanji.

And a top paper layer formed on the lower paper layer and impregnated with microcrystalline white powder in a paper made of paper fiber and pulp.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram showing high-functionality paper according to the present invention; Fig. Figure 2 is a schematic plan view of the top paper layer.

Referring to FIGS. 1 and 2, the high functionality paper comprises a lower paper layer 10, a top paper layer 20, and an adhesive layer 30 applied therebetween.

The lower paper layer 10 and the upper paper layer 20 may be referred to above.

The top paper layer 20 comprises a fiber mat 21, pulp 22 and fine textured powder 23.

The pulp 22 and the dough fiber 21 provide a basic structure of paper having a network structure including pores. Particularly, the core fiber 21 is dispersed throughout the paper. Also, the core fiber 21 forms relatively large pores (pores between the fibers and the fibers) than the paper network formed of only the pulp 22, thereby maintaining the inherent permeability of the paper.

 The talc powder 23 may have a particle size of 50 to 200 mesh as described above.

The texturized powder may be impregnated into the pores or located on the surface of the paper.

The entire thickness of the high-functionality paper may be 90 to 500 탆, preferably 150 to 450 탆.

The lower paper layer 10 may have a thickness of 40 to 200 mu m.

The upper paper layer 20 may have a thickness of 50 to 300 mu m.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
