It is a kind of sewing thread with conductive fiber or anti-static fiber implanted in the sewing thread.
It USES two kinds of materials, polyester fiber staple and polyester fiber filament, and high-tech anti-static material to produce conductive sewing thread.
In order to eliminate the static electricity of the fiber and its fabric and prevent the harm, the development of conductive fiber has been started since 1960s.
Conductive fibers generally refers to the resistivity < 10^8 Ω · cm fiber (20 ºC, 65% RH conditions).
