Description

technical field [0001] The invention relates to the technical field of textile manufacturing, in particular to a preparation method of a graphene composite conductive fiber textile. Background technique [0002] Conductive fibers have always been a research hotspot for functional fibers, generally referring to fibers with a resistivity less than 108Ω·cm, which have the functions of conduction, electric heating and anti-electromagnetic radiation, and are usually concentrated in anti-static clothing or anti-electromagnetic radiation used in special occasions Clothing and other fields. [0003] The main methods for the manufacture of conductive fibers include: one is to coat the surface of conventional fibers with conductive components, and the other is to mix conductive materials with fiber raw materials and make conductive fibers by spinning. The method of coating the conductive layer on the surface of the fiber is to coat the conductive material containing metal, carbon bla...
