Conducting fiber and preparation method thereof

Abstract

The invention provides conductive fibers and a preparation method thereof. The preparation method comprises the following steps that: firstly, the fibers are subjected to warping; secondly, the warped row of fibers is subjected to plasma processing; thirdly, the processed fibers are plated by vacuum physically to generate a physically plated metal coating, the order of magnitude of the specific resistance is between 10<7> and 10<0>Omega.cm; the metal coating is mainly used for being anti-static and sterilizing clothes; a metal layer is plated outside the physically plated metal coating, the order of magnitude of the specific resistance is less than or equal to 10<0>Omega.cm; the metal layer is mainly used for shielding electromagnetic wave and absorbing materials; and the plasma processing comprises the ion beam processing or the negative bias addition. The preparation method has simple technique, low cost, and strong feasibility of the industrial production on a large scale. The manufactured conductive fibers have the characteristics that the product is combined firmly, the dyeing property and the conductivity are good, the chemical resistance and the wash resistance are good and the tactility is soft.

Description

Technical field: [0001] The invention relates to a conductive fiber and a preparation method of the conductive fiber. Background technique: [0002] Synthetic fibers are prone to static electricity during use, which will cause harm to industrial production and people's lives. With the development of high technology, the consequences of electrostatic hazards are not limited to safety issues. The spectrum interference hazards caused by electrostatic discharge are in electronics, communications, aviation, aerospace and all occasions where modern electronic equipment and instruments are used. One of the direct causes of operation failure, signal loss, and bit error. [0003] In industries such as petroleum, chemical industry, precision machinery, coal mining, food, and medicine, there are special requirements for electrostatic protection; with the rapid development of microelectronics, precision processing, and biochemical pharmaceutical technology, the requirements for dust-fr...
