Problems solved by technology

[0006] As mentioned above, at present, the insulation, tensile strength and tear resistance of meta-aramid paper are relatively good, but the surface is relatively smooth, it is difficult to absorb ink, and the fiber texture of the paper surface is poor, so it cannot be used as paper for calligraphy and painting.
In traditional ironing, the braided fabric is pressed under hot and humid conditions, and the surface of the fabric is flattened, and the yarn is flattened to make the surface of the fabric smooth. It can be seen that ironing only makes the surface of the fabric even and does not change the fibers on the surface of the fabric. Texture, which has not been involved in the literature so far, applies ironing to the post-processing technology of paper

Abstract

The invention discloses a preparation method of meta-position aramid fiber insulation paper. The preparation method is characterized in that meta-position aramid fiber chopped fibers and meta-position aramid fiber pulp are used as raw materials, and a composite multilayer oblique-net wet-method papermaking process and an ironing heat treatment process of a given clearance and temperature are adopted. According to the preparation method, the needed raw materials can be prepared at any time, the raw materials are sufficient, the production process is simple, the produced meta-position aramid fiber paper is resistant to tearing, aging and high temperature, can be used for absorbing ink easily, cannot be burned easily and is easy to store, the surface of the paper is high in fiber texture, and the weaknesses that the rice paper made in a handmade method cannot bear a huge pull force and is likely to tear can be overcome, so that the precious calligraphy and painting can be preserved for a long time, and a great contribution can be made for carrying forward the Chinese nation culture.

Description

technical field [0001] The invention relates to the preparation of an artificial synthetic fiber paper replacing the national treasure rice paper, in particular to a preparation method of meta-aramid paper, which belongs to the technical field of synthetic fiber paper. Background technique [0002] Xuan paper has played an indelible role in the cultural inheritance of the Chinese nation for thousands of years. However, sandalwood, the raw material of rice paper, is a non-renewable resource, which is less and less in nature. The higher the price, the more costly the preparation of rice paper, and the more expensive it is, and the rice paper cannot withstand large tension, it is easy to tear, it is not resistant to high temperature, and it is flammable, so that precious calligraphy and painting works cannot be well preserved. Therefore, there is an urgent need for a paper product that can replace rice paper to appear. [0003] Meta-aramid fiber is a soft, white, slender, fluf...
