aramid conductive fiber: perfect combination of flame retardant and antistatic

Conductive fiber is a new type of fiber which appeared in the 1960s. 1t usually refers to the specific resistance (or resistivity) of 107 under the standard state (20 ℃, 65% relative humidity) Ω- Fibers less than 1 cm. Generally, conductive fibers can be divided into inorganic and organic. Among them, inorganic fibers include all kinds of metal fibers, and organic fibers include nylon, polyester, acrylic, polypropylene, polyester / Polyamide Composites, etc< With the development of society and the continuous progress of modern science and technology, the anti-static demand for flame retardant fabrics in military and civil fields is increasing, and the performance standard of conductive fibers is also improving. At present, the commonly used flame-retardant fabrics in the market are mainly cotton flame-retardant fabric and aramid fabric. 1n order to meet the need of anti-static, these fabrics will generally add about 2% polyester or nylon based conductive fiber nylon based and polyester based conductive fibers do not have flame retardancy, and flame retardant fabrics often affect their original combustion supporting properties because of the addition of these conductive fibers. 1n order to solve this problem, Yantai Taihe new materials Co., Ltd. developed a new type of conductive fiber based on meta aramid the fiber is the first aramid based conductive fiber in the world, which has excellent conductivity and specific resistance of 104 at room temperature Ω- cm. At the same time, it retains the original excellent flame retardant properties of aramid fiber, and its limiting oxygen index can reach more than 28%. 1t is an intrinsic flame retardant fiber and will not burn, melt or produce molten droplets in the air compared with other conductive fibers, aramid based conductive fibers can effectively enhance the flame retardancy of fabrics. The LO1 of aramid fabric with 2% nylon or polyester based conductive fiber is 30%, while the LO1 of aramid fabric with 2% aramid based conductive fiber is 39% – 40% due to the difference of high temperature resistance of the matrix materials, the aramid based conductive fibers also show better high temperature resistance than the conductive fibers of other substrates. At 265 ℃ for 5 minutes, the state of aramid based conductive fiber has no obvious change, while polyester based conductive fiber will shrink obviously, and some of them even begin to melt at the same time, the aramid conductive fiber also has the characteristics of low rigidity and high elongation. 1t can be processed into any length and has soft handle. After blended with other fibers, it can not only meet the requirements of antistatic fabric, but also improve the flame retardancy of the fabric with the increasing emphasis on personal protection in our country, the requirements of flame retardant, antistatic and other special protection in various industries are increasing day by day. With its excellent performance, aramid conductive fiber has been successfully applied in fire-fighting clothing, emergency rescue clothing, petroleum tooling, fire blanket, touch screen gloves and other special protection fields. At present, the high-tech textile market is growing rapidly, the protective clothing industry is growing at an average annual rate of 6% – 10%, and some special demand areas even grow at an annual rate of 30%. Aramid based conductive fibers will be widely used in more and more fields
