The obtained mixture is stirred, mixed, then formed into paper with a drainboard, dehydrated and dried.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing paper based on butterbur fibers.

[0002]

2. Description of the Related Art Conventionally, butterbur has been widely used as an edible material and is used as a preserved food prepared by boiling or salting. However, since the epidermis part contains a lot of fiber and other ingredients, it is not suitable for edible use. It was thrown away.

[0003]

[Problems to be Solved by the Invention] The butterbur is a perennial plant of the Asteraceae family, which grows naturally in various parts of Japan.
This petiole epidermis has no other use than discarding as described above, and no place to discard is specified. Most of them are discarded in the wilderness, river premises, etc., but this epidermis contains chlorophyll, pectin, polyphenols, etc., which oxidize over time after disposal and corrode even the flowers and buds of the place. , Contributes to environmental pollution. The present invention has been invented with the object of solving the environmental problems that accompany the conventional disposal of butterbur epidermis and providing a new method for using the butterbur epidermis.

[0004]

[Means for Solving the Problems] As means for solving the problems in the preceding paragraph, the present invention is a method of removing water by dipping in water (removal of impure components contained), dispersion of butter fiber, and adjustment by adding fiber dispersion auxiliary The process was completed by dehydration and drying. That is, the epidermis of the butterbur is exposed to water and then steamed, and the fibers are dispersed by repeated pressurization as a raw material. To this raw material, water, pulp, and a fiber dispersion aid (troloois) are added, and the mixture is stirred and mixed. Strain, dehydrate and dry. The present invention is a method for producing paper using the soba fiber having the above constitution.

[0005]

In the process of the present invention, the buttery epidermis is first exposed to water, whereby chlorophyll and other components contained in the buttery epidermis can be dissolved and removed in water.
It is then steamed in heated steam, which softens the epidermis. Then, the butter fiber is dispersed by the repeated mechanical pressing. A beater or beater is used for this. The disintegrator mainly comprises a concave portion into which the raw material is inserted, a rod-shaped body that repeatedly strikes the surface of the concave portion, and a drive source for the rod-shaped body, and disperses the raw material fibers accommodated in the concave portion. Further, the beater rotates two rotors having parallel grooves that are engaged with each other, which are provided in a circulating water tank, to disperse a raw material passing between the rotors together with water into fibers. These devices are properly used according to the type of paper to be manufactured. Then, add water, pulp, and fiber dispersion aid (troloois) to the raw material after fiber dispersion and stir it.
Although they are mixed, the dispersion efficiency can be increased by using this fiber dispersion aid. Then, after the above steps, it is completed by straining with a dashi, dehydrating and drying. It should be noted that it is efficient to use a press at the time of dehydration. Further, although shrinkage of the paper occurs during drying, the deformation due to shrinkage can be prevented by spraying the paper surface during drying, as will be described later in Examples.

[0006]

EXAMPLES Examples of the present invention will be described below. First step: First, 4 kg of the epidermis peeled from the petiole is put in water to remove the scum for about 24 hours. As a result, chlorophyll and other components in the epidermis can be removed. Next, the epidermis pulled up from water is cut into a length of 2 to 4 cm, put in a pressure cooker, steamed at 1.5 atm for 25 to 30 minutes, and left to cool in the container for about 12 hours. Second step: Next, depending on the type of paper to be manufactured, the butter fiber is dispersed using a beating machine or a beater. Third step: 250 l of water is put in a filter tank, 2 kg of fiber-dispersed butterbur fiber raw material, 500 g of pulp
Put in a tank and stir and mix for 10 to 15 minutes. Fourth step: scoop the mixed raw material into a strainer and shake it back and forth in the water left and right (flowing straining) Repeat this several times,
Depending on the amount of water remaining in the baby's bowl, water is collected and drained. Then, it is strained on a wet paper board, sandwiched with a cloth and the next wet paper is strained, and after repeating this, leave it for 20 to 30 minutes while lightly weighting it to drain water. Fifth step: The wet paper on the wet paper board is transferred to a press and gradually pressurized to further remove water. The pressurizing time is preferably about 10 hours. Sixth step: The wet paper after pressure dehydration is attached to a dry iron plate and dried. At this time, contraction occurs, so spraying is carried out again, and it is put in the pressing machine again, and this operation is repeated several times until the contraction disappears while observing the dry state to obtain the final paper.

In this example, steaming is performed under pressure by the pressure cooker in the first step, and the treatment can be performed in a shorter time. Further, as the pulp, a crushed product of a milk pack was used in this example. This is one in which a commercially available milk container is roasted, the surface synthetic resin is stripped off, the surface is immersed in water for a while, and then the mixture is mixed with a mixer to form a pulp. In addition, the Trolo mallow used in the third step is a sap of the skin of Nori Tsuugi (glutinous wood), has an action of promoting the fiber dispersion of the raw material, and makes it easier to peel off the wet paper from the dashi. In this example, although pulp is also used, the pectin substance is contained in the butterbur epidermis, so the mixture will have a waxy finish up to a mixing ratio of 70% butterbur pulp and 30% pulp, and pulp, Mitsumata, Kozo, etc. The paper mixed with and strained shows the unique color and pattern of the butterbur skin. Depending on the process and mixing ratio described above, it can be used for various fields such as business cards, postcards, stationery, strips, colored papers, diplomas, wrapping papers, wallpapers, picture papers, and molded products such as pen plates, accessory cases, key chains, etc. Can be expected to be used.

[0008]

According to the present invention, it is possible to obtain a new utilization method of the butterbur epidermis which has no other means than discarding it, and it is possible to prevent environmental pollution due to disposal. In addition, the paper according to the present invention has a high utility value as a craft paper by taking advantage of the unique color tone that shows the light green and brown color possessed by the butoh fiber, and by making other papers, business cards, postcards, colored papers, etc. It is possible to provide a useful method for producing paper that can be applied to various articles such as application to paper, raw materials for paper viscosity, and small articles.
