JPH04146282A - Production of japanese paper using vegetable fiber - Google Patents

Abstract

PURPOSE:To obtain Japanese paper having the same touch, strength and beauty as those of conventional Japanese paper from a raw material having low use value by boiling skin, stem, etc., of maize, beating into a pasty state, putting in a paper making tool, making into paper and drying. CONSTITUTION:Skin, leaf or stem of plant such as skin, stem, etc., of maize, leaf, stem, etc., of sunflower or leaf, stem, etc., of Japanese knotweed is boiled, beaten into a pasty state, put in a paper making tool, made into paper and dried to give the objective Japanese paper.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is a method for producing Japanese-style paper using plant fibers of corn husks, leaves, and stems.

<Conventional technology> In the past, corn husks, leaves, and stalks had industrial value only as fertilizer for dairy farming, and were otherwise thrown away or incinerated to be used as fertilizer for fields. Sunflowers also produce vegetable oil from their seeds, but the leaves and stems are either thrown away like corn or are incinerated and used as fertilizer for fields. Furthermore, the Japanese knotweed that grew everywhere was simply a weed and had no useful value.

<Problems to be solved by the invention> From the perspective of the global environment, the logging of timber has been criticized around the world as a criticism of Japan, and is actually on the verge of a global crisis. However, the reality is that in modern society it is impossible to imagine a society without paper.

It takes several decades for a tree to grow to the point where it can be used industrially. However, as society progresses at such a rapid pace, the demand for paper has increased, and paper recycling has become an urgent need. However, even if paper is recycled, there are limited resources, and new means of securing resources will be needed. Is it possible to find a resource other than wood to secure this resource?

The present invention has been made in order to solve this problem of securing resources.

A Japanese-style method that uses vegetable fibers made by boiling corn husks, leaves, and stalks at high temperatures, beating them into a paste, putting them in a paper machine, straining them, and drying them. Method for producing paper A method for producing Japanese-style paper using the plant fibers constructed as described above (Example) Examples of the present invention will be described below.

Cut corn husks, leaves, and stalks, add a small amount of 15-25% caustic sorter, boil, wash away the waste liquid with condensed water, beat or rub with a brush or hand, remove dust, and turn into selected pulp at room temperature. The pulp is bleached and dehydrated to a moisture content of 80% to make a pulp solution of a certain concentration, and after adding glue, a certain amount is poured into a container, and transferred from the container to a drying board to dry.

Since the present invention is configured as described above, conventionally, materials that have no use value as fertilizer are discarded or destroyed, but from the standpoint of protecting global environmental resources, it can be used as an auxiliary resource as a paper resource. It is possible to produce corn every year in a planned manner, and it has great utility as a by-product of corn, a food production process.

Furthermore, by using the plant fibers described in Section 1, Section 2, and Section 3, it is possible to manufacture Japanese-style paper using plant fibers from sunflowers, Japanese knotweed, and other plants that can be produced in a planned manner. be.

<Effects> Japanese paper made from corn husks, leaves, and stalks has a different texture, strength, and beauty compared to conventional washi paper, and is used by mixing 50% of conventional pulp. It can also be used as a material for non-woven fabrics.

In addition, as mentioned above, from the perspective of protecting the natural environment in the global environment, artificial planned cultivation that can secure paper materials in a short period of time is effective, along with future reuse of waste paper. be.
