Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a thin paper formed mainly of a non-wood fiber material, a thread or a string formed of the same material, or a thin paper thread obtained by processing the thin paper. Or about the string.

[0002]

2. Description of the Related Art Conventionally, Japanese paper was collected by collecting the bast fibers of shrubs cultivated, such as mulberry and mitsumata, and adding a binder (paste) to form paper. On the other hand, if the purpose is to produce in large quantities and inexpensively for office use, packaging, etc., mainly coniferous and hardwood are used as materials, and the raw wood is crushed and alkali is added to obtain pulp by digestion. . The obtained pulp is liberated and beaten in water, and a paper is formed by adding a sizing agent (a binder for fibers), a filler and the like to a paper. These papers have been cut into narrow and twisted yarns to be processed into strings, or, if necessary, combined with other auxiliary materials and pressed and processed into boards or the like to obtain secondary paper products.

[0003]

A conventional paper or paper product made of such a raw material is characterized in that in the case of the former Japanese paper type paper, the fiber length of the above-mentioned raw material of the Japanese paper is long and the paper fabric is tough. However, it is difficult to obtain a large amount of raw materials, so that it is expensive and cannot be mass-produced. On the other hand, paper using wood pulp can be mass-produced, but it cannot be said that it is a preferable means from the standpoint of the global environment because of the cutting and dusting of raw wood and the use of large amounts of chemicals. However, there is a problem to be solved in that it is difficult to produce paper having a strength comparable to that of paper.

[0004] In order to solve the above-mentioned problems, the present invention is to mass-produce inexpensive plant materials and unused materials, to provide a low-priced product, tough and safe to use as a building material. It is harmless, and when it is disposed of, it is easily decomposed by bacteria and enzymes even when it is left in the soil as it is, and it does not generate harmful substances even when incinerated. The purpose is to provide.

[0005]

The means of the present invention taken to achieve the object will be described in terms of common terms with the description of the embodiments. The non-wood fiber product of the first invention belongs to the Grass family. It is formed in the form of paper using non-wood fibers obtained as a main component, individually or as a mixture, of fibers of a circulating plant, a palm plant or a harvested plant commonly called hemp.

[0006] The non-wood fiber product of the second invention is a non-wood fiber product obtained by singly or by mixing fibers of a circulating plant belonging to the Poaceae family, a palm plant or a harvesting plant commonly called hemp. It is formed in a thread or string shape as a main component.

[0007] The non-wood fiber product of the third invention is a non-wood fiber product obtained by singly or by mixing fibers of a circulating plant belonging to the Poaceae family, a palm plant or a harvesting plant commonly called hemp. It is formed by cutting and twisting a paper-like product as a main component into a thread or string.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The thin paper, thread, string,
In addition, in order to implement the thin paper thread or string, the material used is the stem, stem,
Non-wood fiber materials such as fibers of skins, cores, etc., fibers of palm stems, stems, skins, cores, etc., fibers of harvested plants usually called hemp, such as Manila hemp, jute, ramie etc. . First, non-wood-based materials such as stems, stems, skins, and cores of circulating plants and palm plants are ground into chips and powders, and then ground into powdered pulp and pulp sheets. Alternatively, in actual production, the powdered pulp or pulp sheet may be dissociated into mud by adding water in a dissolution tank to form a suspension.

Next, the fibers of the harvested plant called hemp are exposed to water and boiled to obtain hemp pulp mainly composed of hemp fibers. The hemp pulp is dissociated into a mud obtained from the circulating plant and mixed with the suspended powder pulp and pulp sheet. The mixed pulp suspension thus obtained is made into a thin paper of the first embodiment. The mixing ratio of hemp pulp is preferably 50% or more in order to maintain the strength of the thin paper. In addition, among the circulating plants, plants belonging to the Poaceae family of the Poaceae generally have large fiber lengths and are excellent in increasing the strength of paper. The mixing ratio of bamboo pulp is desirably 30% or more. or,
If necessary, mulberry, wood pulp, seaweed paste, starch paste, etc. may be used in increasing amounts and used as a binder, but the mixing ratio is 0%.
(Do not mix) ~ 30%.

[0010] The thin paper of the first embodiment is different from a conventional paper mainly made of wood pulp by a synergistic action of mixing fibers of a circulating plant such as bamboo or a palm plant and fibers of a crop plant such as hemp. In comparison, the tensile strength is about three times or more.
Also, since other embodiments have a similar high tensile strength, they can be formed slender and thicker than thin paper and used as a thread or string as they are. Alternatively, the thin paper can be cut into a band having a width of about 1 to 15 mm, and twisted to form a thread or a string. In addition, these thin papers, yarns, strings, etc. are subjected to secondary processing to produce knitted strings, woven fabrics, curtains, etc., as well as wallpaper, fusuma paper, floor coverings, etc., which are conventionally inorganic and petroleum products, etc. It is possible to manufacture a wide variety of products in the field of articles made of materials consisting of:

The bamboo fiber mixed with the wood fiber product of the present invention and having the effect of increasing the strength has a remarkable antifungal and antibacterial effect, and is mixed in the pulp material with 30% (preferably 70%) or more. When used as a surface covering material for a house, the room is kept clean, and since it is made of only natural materials, no harmful gas such as formaldehyde is generated.

The wood fiber product of the present invention has a wide range of moisture control of 7% to 25% by lowering the pressing pressure. When the humidity in the surrounding air increases, it adsorbs water vapor and lowers the humidity. When the humidity decreases, the adsorbed water vapor is released to automatically adjust the humidity to an appropriate level. Therefore, when used as a surface covering material for a house, the bamboo fiber, combined with the antifungal and antibacterial effects of the bamboo fiber and the effect of eliminating the cause of harmful gas generation, protects the respiratory organs and protects the room when used as a house interior material. Since it is always kept clean, it is extremely effective in preventing respiratory diseases and sick house syndrome.

[0013] Further, since the raw materials are only natural materials, even if they become waste materials after use, they can be incinerated at low temperatures, so that the incinerator is not damaged and no dioxin is generated. Furthermore, even when buried in the soil as it is, it is biodegraded by bacteria and enzymes in the soil to become fertilizer, which contributes to soil improvement and contributes to purification of environmental hygiene.
