Description

Korean paper including greens and crafts using the same {Korean paper including green laver and crafts of the same}

The present invention relates to a Korean paper comprising a seaweed and a craft using the same, and more particularly, to a paper comprising pulp and docule prepared from the seaweed.

As the paper manufacturing technology develops day by day, a variety of papers are provided with various functionalities such as high strength, antimicrobial and deodorant, and beautiful colors and patterns. However, many of the additives for providing functionality or decorative properties are synthetic chemicals, and these additives are materials that do not meet the demands of demanding consumers who want to satisfy various conditions such as stability and eco-friendliness at the same time as functionality and decoration. Therefore, there is an urgent need for the development of natural materials with stability and eco-friendliness along with functionality and decoration.

The green grass grows in the upper part of the intertidal zone of the seashore, especially where fresh water flows, and forms a large colony in a quiet tide pool. In Korea, there are intestinal, flat, leaf, spiny, lattice, etc., and the brown seagrass is distributed in the coastal area of Jeju Island, and the brown seaweed is also distributed in some bays. During the period of autumn to early summer, seawater temperature in the coastal area of Jeju Island is 15 ~ 20 ℃, while other seaweeds gradually disappear, while perforated blue sea continuously grows from the coastal intertidal to the subtidal zone where nutrient-rich freshwater enters. Form a colony. In the summer when the sea temperature rises, the large-grown seaweed is pushed to the shore and deposited on the shore according to the flow of algae, and the deposited seaweed not only causes bad smell and pest breeding, but also harms the aesthetics of the beach. Blue seaweed is causing the fisheries to be devastated.

Therefore, by exploring ways to use the seaweed as a resource, it is possible to reduce the cost of disposal of the collected seaweed as well as to prevent the deterioration and environmental damage of the fishery by activating the collection of overgrown seaweed. The present invention provides a paper and a craft using the same as the seaweed as a utilization method.

In the present invention, by providing a method of utilizing the waste to be discarded as a resource, by activating the collection of over-proliferated seaweed not only to prevent wasteland and environmental damage of the fishery, but also to reduce the cost of disposal of the collected seaweed I want to save.

In addition, in the present invention, by using as a raw material of the blue, the feel is soft and natural pattern to give a luxurious feeling, excellent overall strength and to provide a variety of uses and crafts using the same.

In order to achieve the above object, in the present invention, the fiber is extracted from the green seedling to obtain the green pulp, and then mixed with the pulping pulp to prepare the hanji.

In the present invention, the seaweed pulp is prepared by cooking seaweed, specifically, washed with water to remove foreign matters such as salt, soil, etc. Put the seaweed in a sodium hydroxide solution of 2 to 5% by weight, boil and cook, and then take out the fiber After removing and selecting foreign matter, it can be prepared by washing with water and dehydrating.

In the present invention, water is added to the pulp mixture in which the green pulp and the duck pulp are mixed so that the water content is about 90%, and then, according to a conventional method for preparing Korean paper, a viscous mixture is mixed, papermaking, dehydration, and drying to prepare Korean paper. . In the pulp mixture, if the mixing amount of the green pulp is too small, the effect of increasing the theft resistance and the waste resource utilization and the cost reduction effect are reduced. On the contrary, if the mixing amount is too large, the binding between the fibers is not dense and the volume is increased and a thin paper is produced. Since there exists a disadvantage that it becomes difficult, it is preferable to include in 5 to 80weight% of a range based on dry weight.

In addition, in the pulp mixture, it is possible to prepare a hanji with additional functionality by including additional ingredients in addition to the pulping pulp and green pulp, when the mixing amount of the pulp in the pulp mixture is too small paper quality Since it can not exhibit the inherent characteristics of the hanji, it is preferable that the pulp of more than 10% by weight based on dry weight.

Examples of additional components to be included in the pulp mixture include citrus foil pulp, which is a non-wood pulp. Citrus foil pulp is a method of washing citrus peels from which impurities are removed and cooking them for 2 to 5% by weight in sodium hydroxide solution for 20 to 50 minutes. It can be manufactured by maximizing cost-saving effect by mixing citrus fruit pulp, as well as expressing beautiful colors and patterns. If too little citrus pulp is included in the pulp mixture, the desired effect will not be sufficiently achieved. If too much citrus pulp is contained, the bond between the fibers will not be dense, resulting in increased volume and reduced strength. It is preferable to include in the range of 5-50 weight%.

Another example of an additional component to be included in the pulp mixture is a non-wood pulp, which is a non-wood pulp, which is boiled in water for 1 hour after removing the impurity, and then the fibers are boiled. After cooking for about 30 minutes in the solution, the fibers may be removed to remove foreign substances, selected, washed with water and dehydrated.

Hanji containing scallop pulp is characterized by excellent moisture permeability and anti-mildew. Therefore, when Hanji pulps mixed with chopped pulp is used as a food packaging material, it is possible to obtain the effect of preventing deterioration in the distribution process. If the amount is too small, the moisture permeability and the anti-mildew effect is inferior, and if the mixing amount is too high, the bond between the fibers is not dense and the volume may increase and the strength may be reduced. It is preferable to include in the range.

Another example of the additional components to be included in the pulp mixture may be a mixture of volcanic stone powders to make Hanji. If the volcanic stone particles mixed in the pulp mixture are too large, the paper becomes uneven, and if the particles are too small, the time or cost required for grinding increases, so it is preferable to use volcanic stone that has been crushed to a particle size of 10 to 75 μm.

Since volcanic stone exhibits antibacterial, volatile organics removal, heavy metal adsorption, and far-infrared radiation, it can be used as wallpaper for the addition of volcanic stone to prevent sick house syndrome and improve health. If the mixing amount is too small, the effect of antibacterial, volatile organics removal, heavy metal adsorption, far-infrared radiation, etc. will be less effective. On the contrary, if mixing too much, the strength of the paper will be reduced and the texture will be degraded. It is preferable to include in the range of 5 to 50% by weight.

Hanji of the present invention prepared by using a pulp mixture containing a pulping pulp and green pulp as described above gives a soft feeling and a natural pattern of green-based, giving a luxurious feeling, the strength in particular, particularly excellent in corrosion resistance, deodorant, It is characterized by having antimicrobial properties. Therefore, the hanji including the green according to the present invention can be used for the production of various crafts such as wrapping paper, wallpaper, packaging bags, packaging boxes, disposable machines, clothing, bags, hats, ties, curtains, vertical, lighting and the like.

In the present invention, by providing a method of utilizing the waste to be discarded as a resource, by activating the collection of over-proliferated seaweed not only to prevent wasteland and environmental damage of the fishery, but also to reduce the cost of disposal of the collected seaweed Helps to save In addition, the hanji comprising the green produced according to the present invention is soft to the touch and exhibits a natural pattern gives a luxurious feeling, excellent overall strength has the advantage that can be used for various purposes.
