Problems solved by technology

[0004] Although there are many methods for preparing conductive fibers nowadays, there are some disadvantages in these preparation methods. For the conductive fibers prepared by the three methods 3, 4, and 5, the conductive layer on the surface of the fiber is easy to fall off during use, so that the fabric cannot be used. Long-term conductivity, 2. Fabrics woven from conductive fibers prepared by methods 1 and 2. Although they have long-term conductivity, the strength of the fabric will be greatly affected.
