The present invention relates to a method for producing a wide variety of color-changed recycled paper manufactured by hand making or machine making.

[0002]

2. Description of the Related Art Coloring on conventional recycled paper is performed by first,
The raw material waste paper is disintegrated, bleached by flotation treatment or chemical bleaching, and then colored with a dye. Therefore, the production of recycled paper requires a large amount of chemicals and water, and wastewater from a recycled paper production plant has been an important environmental issue. Recycling used paper requires complicated labor such as special mechanical equipment and chemicals, and the recycled paper tends to be expensive. Recycled paper produced in this way or products using it are sold as stationery and daily necessities, but they are not bleached with chemicals or dyed with coloring agents. And other uncolored paper (in the case of packs with resin coating, the resin film is completely peeled off) and industrial waste paper such as colored paper and backing paper, and other waste materials. There has not yet been proposed a method of producing recycled paper that is environmentally friendly and has a high recycling effect by using colored paper (wrapping paper, drawing paper, colored paper dust, etc.).

[0003] Speaking of recycled paper products, products that cannot meet the needs of consumers with poor design,
Household goods (toilet paper, cardboard, etc.) account for the majority of the total. However, when making recycled paper by hand-making or machine-making using the mixed-color paper pulp according to the present invention, foreign substances such as plants are made. In addition, there has not yet been proposed a method of producing recycled paper having a better design.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and does not use any bleaching with a chemical or coloring with a dye. It is still another object of the present invention to provide a manufacturing method capable of manufacturing recycled paper having abundant color variations and design properties according to consumer needs.

[0005]

In order to achieve the above object, the method for coloring recycled paper according to the present invention uses industrial waste paper such as top blank paper and top mount paper or other uncolored paper (the surface of which is coated with resin). Packs are made from blank paper pulp made from completely peeled resin film), industrial waste paper such as colored paper and backing paper, and other colored paper that becomes waste (wrapping paper, drawing paper, colored paper trash, etc.). The process is characterized in that a mixed color paper pulp of a designated color is produced by mixing and mixing the colored paper pulp thus obtained, and then the recycled paper is manufactured by hand-making or machine-making to produce recycled paper that does not use any chemicals or dyes.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The method for coloring recycled paper according to the present invention is intended for use with industrial waste paper such as top blank paper and top mount paper, and other uncolored paper (such as packs whose surface is coated with resin). A blank paper pulp is manufactured by a manufacturing process in which the film (with the film completely peeled off) is crushed and stirred by a pulper mixer or the like to form a pulp. Industrial paper such as colored paper and backing paper, and other uncolored paper (wrapping paper, drawing paper, colored paper garbage, etc.) are immersed in water in the blank pulp produced by the above process, and then pulp / mixer etc. Color paper pulp manufactured by the manufacturing process to make pulp by crushing and stirring is mixed and mixed, and a colored pulp colored to the specified color is manufactured, and it is hand-made or machine-made to make recycled paper. It is environmentally friendly because it does not use any chemical bleaching or dyes, and it contributes to the use of recycled resources because all waste materials are used.

[0007]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings. Therefore, first, the most basic production of colored recycled paper will be specifically described.

First, as shown in FIG. 1, water 2 is poured into a water tank A1. Into the tank 2, there is used industrial paper such as upper blank paper, upper mount paper, etc., and other uncolored paper 3 (pack having a resin-coated surface). In such a case, the resin film completely peeled off) is immersed all day and night. In order to soften the resin coating removed to such an extent that the resin coating can be crushed and stirred, the immersion in a water tank for two days and nights is further crushed and stirred by a pulper mixer or the like to produce a white paper pulp 4.

At the same time, industrial waste paper such as colored paper and backing paper for use in coloring, and other uncolored paper (wrapping paper, drawing paper, colored paper dust, etc.) 5 are immersed in water 7 in a water tank B6 and immersed in it all day and night. Is crushed and agitated by a pulper mixer or the like to produce colored paper pulp 8. The above is the manufacturing process of the white paper pulp and the colored paper pulp. Table 1 shows specific amounts and the like.

[Table 1]

[0010] To produce beautiful colored recycled paper, when producing colored paper pulp, uncolored paper (wrapping paper, drawing paper, colored paper trash, etc.) used as industrial waste paper such as colored paper and backing paper, and other waste materials. It is necessary to sort the paper by color system, and to remove wrapping paper, colored paper dust, etc. from adhering cellophane tape, adhesive labels and the like. In addition, when printed with black ink, when producing beautiful colored recycled paper, color contamination is generated, so remove it or use it when manufacturing colored recycled paper with high density and darkness. .

As shown in FIG. 2, a mixed color paper pulp 11 having a desired color is manufactured by mixing a color paper pulp 8 with the white paper pulp 4 manufactured by the above process. At this time, stirring the inside of the water tank well is the point of producing recycled paper without color unevenness.

[0012] For the crushing and stirring during the production of paper pulp, it is necessary to take time to loosen the fibers at a low speed so as not to cut the paper fibers. In addition, this is a factor that gives the strength of the produced recycled paper. Recycled paper can be manufactured without using any chemicals by taking the time-consuming step of loosening the fibers at a low speed so as not to cut the paper fibers.

Recycled paper is manufactured by hand-making or machine-making the mixed-color paper pulp manufactured by the above process.
No glue or other additives for producing recycled paper are required.

Example 2 Using the mixed pulp produced by the above process,
When making recycled paper by hand making or machine making,
Incorporate plants. As for the plants to be mixed, those that easily become dried flowers do not lose color and have a beautiful finish. According to the manufacturing method of the present invention, stationery items such as postcards, cards, envelopes, and stationery, living goods such as coasters and lunch mats, and the production of "recycled art" that can be used for decoration and interior by incorporating flowers and the like. Is also possible. Example 3 It is also possible to manufacture recycled paper having completely different colors on the front and back surfaces depending on the method of making.

As described above, according to the production method of the present invention, it is possible to produce beautiful recycled paper having no design problem and a wide variety of colors in accordance with the needs of consumers without worrying about environmental pollution. It is also effective as a means to effectively use limited resources. In addition, this can be said to play a large role in the general society in enlightening the goodness of recycled products. By not using chemicals, dyes, or fire, it can be practiced at school and home without danger, so it is also very useful for learning about environmental issues and raising awareness of recycling for children, students, general consumers, elderly people, etc. You can say that.
