Abstract

PURPOSE:To form nonwoody paper usable for various applications with a simple apparatus by using a material, close to wood fiber and readily available at a low cost such as a stem, a leaf or a root of an annual or a perennial herb as a raw material. CONSTITUTION:This method for producing nonwoody paper is to dry a stem, a leaf or a root of an annual or a perennial herb similar thereto such as tobacco or Corcharus oltorius L. (mulukkiyya) having a fibrous tissue close to that of wood fibers, cut the dried stem, leaf or root to a desired length, then loosen the cut material, add an alkaline liquid such as caustic soda thereto, digest the resultant mixture, convert the mixture into a pasty form, subsequently add water thereto and form sheets of paper. Thereby, the sheets of the nonwoody paper usable as cigarette paper, paper for toilets, sanitary, business or medical paper, paper for games, purifying or hygroscopic paper, water, oil, heat or sound absorbing paper, lightproof, heat shielding, sound insulating or horticultural paper are formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-wood paper, a non-wood paper product, a method for producing a non-wood paper, and an apparatus for manufacturing a non-wood paper, and more particularly, to an annual grass or its having a relatively strong textile texture. Plant stems and / or leaves and / or near perennial grasses
Further, the present invention relates to a non-wood paper, a non-wood paper product, a non-wood paper manufacturing method and a non-wood paper manufacturing apparatus using a root material.

[0002]

2. Description of the Related Art Conventionally, a raw material for paper is wood pulp. Increasing consumption of western paper requires more wood pulp and thus loses forest resources. When the forest was wide and there was enough room, the production of paper made from wood pulp also led to the promotion of industry, much less environmental damage. However, in recent years, forest resource developers who supply wood pulp, which is a raw material for foreign paper, have made efforts to secure forest resources by limiting the supply of wood pulp in order to prevent the decrease of forest resources. On the other hand, even in developing countries, they are trying to make timber with higher added value, and by their spare capacity, they are working to cultivate and strengthen various industries and are aiming to become industrialized countries. Such a situation is predicted to become more and more serious from now on,
Drastic measures are needed. By the way, tobacco is an annual grass that is used as a material for tobacco by sowing seeds in spring, growing in summer and harvesting leaves in autumn. Post-harvest tobacco stalks are discarded without any other suitable use, but because they do not decay easily, they have been incinerated.

[0003]

Therefore, until now, the leaves are harvested and the stems of the tobacco after harvesting the annual grass, which has been used as a raw material for tobacco, are not discarded or it is difficult to rot. It is a book to obtain non-wood paper and non-wood paper products from these materials by appropriately treating the plant fiber tissues of the relatively strong post-harvest tobacco stems without incineration, and making them into paper materials. It is a first object of the invention, and a second object of the present invention is to provide a non-wood paper manufacturing method and a non-wood paper manufacturing apparatus. In addition, a plurality of plants such as annual grasses or perennial grasses having relatively strong plant fiber tissues are prepared, and the stems and / or leaves and / or roots of the plurality of plants having a desired quantitative ratio are used as paper materials. The third object of the present invention is to obtain non-wood paper and non-wood paper products from those materials, and to provide a non-wood paper manufacturing method and a non-wood paper manufacturing apparatus. The fourth purpose.

[0004]
