Description

  The present invention relates to a peach paper using a peach tree as a raw material and a method for producing the peach paper.

  Japanese paper has long been known as an ancient Japanese paper. Japanese paper is made from, for example, a mulberry tree. In recent years, one using a bean skin as a raw material has been proposed (for example, see Patent Document 1).

JP 2005-213680 A

  However, plant fibers used as a raw material for paper are limited, and peach tree plant fibers have not been used. In the production of peach fruits, if the grown branches are left unattended, the tree trunk will not be exposed to light and the stock will be weakened. The pruned branch is discarded as industrial waste, and it is preferable if it can be used.

  The present invention has been made based on such problems, and it is an object of the present invention to provide a new peach paper using a peach tree as a raw material and a method for producing the peach paper.

  The peach paper of the present invention contains peach tree plant fibers.

  The method for producing peach paper of the present invention uses plant fibers of peach trees.

  According to the present invention, since the peach tree plant fiber is used, it is possible to obtain a light pink peach paper having a unique texture containing the vertical peach tree plant fiber.

  In addition, peach tree plant fibers and other fibers are used, and the proportions thereof are 10% by mass to 40% by mass for peach tree plant fibers, and 60% by mass to 90% by mass for other fibers. Then, peach paper can be easily manufactured using plant fibers of soft peach trees.

  Furthermore, if pruned branches are used, industrial waste can be used, and environmentally friendly peach paper can be obtained.

It is a flowchart showing the process in the manufacturing method of the peach paper which concerns on one embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The peach paper according to an embodiment of the present invention includes a peach tree plant fiber, and is a light pink paper having a unique texture including a vertically long peach tree plant fiber. Peach tree plant fibers range from short to long, and long ones are about 2 cm long. Peach trees preferably use pruned branches, and plant fibers can be taken from the inner bark, for example. The peach paper preferably contains peach tree plant fibers and other fibers, the proportions of which are 10% to 40% by mass of peach tree plant fibers and 60% of other fibers. It is preferable that they are mass% or more and 90 mass% or less. This is because peach tree plant fibers are soft, and peach paper can be easily produced by mixing other fibers.

  As another fiber, for example, a plant fiber of a mulberry tree is preferable. This is because the texture of peach trees is added to the texture of Japanese paper using kouzo trees, and a new paper texture is obtained. As mentioned above, peach tree plant fibers include vertical ones, so the peach tree plant fibers and short peach tree plant fibers are longer than the light pink peach tree. Plant fibers become present. Therefore, a new texture in which long light pink plant fibers are present in a pattern in a light pink overall is obtained. Other fibers may include plant fibers of apple trees and pear trees in addition to plant fibers of mulberry trees.

  FIG. 1 shows a process of a method for manufacturing peach paper according to an embodiment of the present invention. This method for producing peach paper uses peach tree plant fibers, and it is preferable to use a mixture of peach tree plant fibers and other fibers.

  First, a peach tree plant fiber raw material is prepared as follows (peach tree plant fiber raw material manufacturing step; step S110). In addition, the plant fiber raw material of a peach tree is the plant fiber taken out from the peach tree used as a raw material of papermaking. In the peach tree plant fiber raw material manufacturing process, first, the peach tree is cut into an appropriate size and steamed, for example, for about 1 to 3 hours (steaming process; step S111). It is preferable to use pruned branches for peach trees. Next, the bark of the peach tree is peeled off, and the inner bark is scraped off (skin removal step; step S112). Subsequently, the inner bark is put into an alkaline aqueous solution, and heated, for example, over a period of about 2 to 3 hours to remove impurities and soften the fibers (boiling step; step S113). It is preferable to use an aqueous solution of soda ash as the alkaline aqueous solution. This is because peach tree plant fibers are soft. Next, water washing is performed (water washing step; step S114).

  After producing the peach tree plant fiber raw material, the peach tree plant fiber raw material is mixed with other fiber raw materials to make a mixed raw material, and beaten (separation step; step S120). The other fiber raw material is another fiber used as a raw material for papermaking. The mixing ratio of peach tree plant fibers and other fibers in the mixed raw material is 10% by mass to 40% by mass of peach tree plant fibers, and 60% by mass to 90% by mass of other fibers. It is preferable. Further, as other fiber raw materials, it is preferable to use plant fiber raw materials of mulberry trees, including plant fiber raw materials of apple trees and pear tree plant fiber raw materials in addition to plant fiber raw materials of mulberry trees. May be. In addition, the plant fiber raw material of a sorghum tree is produced by, for example, cutting a sorghum tree to an appropriate size and steaming, peeling off the bark, heating in an alkaline aqueous solution, and washing with water. As the bark, only the inner bark may be used, but the inner bark and the outer bark may be used. As the alkaline aqueous solution, for example, an aqueous solution of caustic soda is used. In addition, if necessary, the plant fiber of the mulberry tree may be bleached when it is desired to make the color white.

  After hitting the mixed raw material, the mixed raw material is mixed with a raw material of bend such as trooi mallow to produce a paper liquid (bending step: step S130). Next, the paper liquid is sown (spinning step; step S140), dehydrated and dried (dehydration / drying step; step S150). This gives peach paper.

  Thus, according to the present embodiment, since the peach tree plant fiber is used, it is possible to obtain a light pink peach paper having a unique texture including the vertically long peach tree plant fiber.

  In addition, peach tree plant fibers and other fibers are used, and the proportions thereof are 10% by mass to 40% by mass for peach tree plant fibers, and 60% by mass to 90% by mass for other fibers. Then, peach paper can be easily manufactured using plant fibers of soft peach trees.

  Furthermore, if pruned branches are used, industrial waste can be used, and environmentally friendly peach paper can be obtained.

  Pruned branches of peach trees were prepared, cut into lengths of about 30 cm to 40 cm, and steamed for about 1 to 3 hours (steaming process; step S111). Next, the bark of the peach tree was peeled off and the inner bark was shaved off (skin removal step; step S112). Subsequently, the inner bark was put into an aqueous solution of soda ash and boiled in a state where it was boiled for 2 to 3 hours (boiling step; step S113), and then washed with water (water washing step; step S114). .

  The plant fiber raw material of the peach tree obtained in this way was mixed with the plant fiber raw material of the mulberry tree to obtain a mixed raw material, which was beaten with a beater (separation step; step S120). The mixing ratio of the plant fiber of the peach tree and the plant fiber of the mulberry tree in the mixed raw material is 10% by mass to 40% by mass of the plant fiber of the peach tree, and 60% by mass to 90% by mass of the other fibers. It was changed within the following range. In addition, the plant fiber raw material of the mulberry tree is cut by steaming the mulberry tree to a size of about 75 cm, peeling the bark, boiling the inner bark and outer bark in an aqueous solution of caustic soda, and then washing with water. Obtained. After that, mixed raw materials of peach tree plant fiber and mulberry tree plant fiber are mixed and mixed with a raw material such as trooi mallow (kneading process: step S130), and sowing (sprouting process; step S140). , Dehydrated and dried (dehydration and drying step; step S150).

  When the plant fiber of peach tree was added within the above range, a light pink peach paper having a unique texture containing a vertically long peach tree plant fiber was obtained. The characteristics of peach paper were stronger when the proportion of peach tree plant fibers was increased. On the other hand, when the proportion of peach tree plant fibers was increased, the strength of peach paper tended to decrease. That is, the ratio of peach tree plant fibers to other fibers is within the range of 10% to 40% by mass of peach tree plant fibers and 60% to 90% by mass of other fibers. It turned out to be preferable.

  Although the present invention has been described with reference to the embodiments and examples, the present invention is not limited to the above embodiments and examples, and various modifications can be made. For example, in the above-described embodiments, the constituent elements of the invention have been specifically described. However, all the constituent elements may not be included, and other constituent elements may be included.

  Can be used for paper.
