Abstract

The invention discloses an acrylic fiber conductive filament and a method for preparing the same by the aid of complexation and doping processes. The acrylic fiber conductive filament and the method have the advantages that acrylic fiber filaments are used as matrixes, bark-shaped surface structures of the acrylic fiber filaments and the electronegativity of -CN are sufficiently utilized, the acrylic fiber filaments are compressed, heated and impregnated in closed acidic copper sulfate solution, Cu2S and CuS on the surfaces of fibers are converted into Cu9S5, certain silver ions are further doped to form a stable complex compound, and accordingly conductive treatment procedures can be carried out on filaments; reaction on the acrylic fiber conductive filament prepared by the aid of the complexation and doping processes is easy to control, colors of the obtained fibers are controllable, and the fibers are high in affinity and excellent in sterilization, deodorization and anti-radiationperformance, and have lasting conductive characteristics.

Description

technical field [0001] The invention relates to the field of functional fiber manufacturing, in particular to an acrylic conductive filament and a preparation method thereof through a complex doping method. Background technique [0002] In order to prevent static electricity and electromagnetic wave interference, people have developed various antistatic products, electromagnetic shielding materials and conductive fibers since the middle of the 20th century. The antistatic effect of conductive fiber is remarkable and long-lasting, and it is not affected by the humidity of the environment. The fiber with excellent conductivity is less than 10Ω·cm. At room temperature, the half-life of the charge on the surface of the fiber is very short. The conductive fabric made of fiber has excellent functions such as electric conduction, heat conduction, shielding, and electromagnetic wave absorption. It is widely used in conductive mesh and conductive work clothes in the electronics and e...
