Abstract
A conductive polyvinyl alcohol fiber having good mechanical properties and heat resistance contains a polyvinyl alcohol polymer and copper sulfide nano-particles having a mean particle size of at most 50 nm which are finely dispersed in the polymer. The content of the nano-particles in the fiber is at least 0.5% by mass/polyvinyl acohol polymer, and the degree of polymer orientation is at least 60%.
