Embodiment Construction

[0008] In actual production, regenerated cellulose fibers or polypropylene nitrile fiber yarns are used to weave fence fabrics, heated to 280°C in an electric furnace at a speed of 10°C / min for pre-oxidation, kept for 2 hours, and continued to be used under the protection of inert gas. Heat the electric furnace to 1000°C at a speed of 15°C / min, and keep it warm for 3 hours to obtain a carbon fiber yarn web with a carbon content of 90%, and continue heating to 2000-3000°C to obtain a graphite fiber yarn with a carbon content of more than 99%. Net, with this net as the base cloth, is made into various non-woven fabrics or wall shielding materials by dry jet spinning.

[0009] The preparation method of the present invention is the following steps:

[0010] ① Spin with regenerated cellulose fiber or polypropylene eye fiber first, and the filament is spun into 10tex / 28f yarn by stretching and other processes to weave into fence fabric, and the warp and weft density are all 25 / 10...

Abstract

The invention relates to a novel weaving method of a carbon fiber electromagnetic shielding textile fabric, which is characterized by comprising the following steps of: utilizing regenerated cellulose fiber or polyacrylonitrile filament yarn to weave a barrier fabric; heating at the speed of 10 DEG C / min of an electrothermal furnace to 280 DEG C, and then carrying out pre-oxidization; carrying out heat preservation for 2 hours; heating at the speed of 15 DEG C / min of the electrothermal furnace to 1,000 DEG C under inert gas protection; carrying out heat preservation for 3 hours; obtaining a carbon fiber yarn mesh with 90 percent of carbon content; heating to 2,000-3,000 DEG C; obtaining a graphite fiber yarn net with more than 99 percent of carbon content; and by taking the net as a base fabric, utilizing a dry method to inject and spin so as to make various non-woven fabrics or wall shielding materials. According to the method, harm of electromagnetic wave to a human body can be shielded well, the spinning process is simple, the production efficiency is high, and better economic and social benefits can be achieved.

Description

Technical field [0001] The invention involves a weaving method of an electromagnetic shielding fabric. Specifically, it is a weaving method that involves a new carbon fiber electromagnetic shielding fabric. Background technique [0002] With the rapid development of electronic technology, there are more and more electronic products and equipment used in people's production and life, and most electronic products such as microwave ovens, refrigerators, electric blankets, computers, radio, radar and other launch devices will be differentA degree of electromagnetic radiation.Electromagnetic radiation not only causes mutual interference between electronic products, but also pollutes the empty question of human survival. It is harmful to human health.EssenceAlthough the penetration capacity of electromagnetic wave transmission is extremely strong, excellent conductive or magnetic conductive materials can be used to shield electromagnetic wave radiation. [0003] At present, the main me...
