DDY-1/DDY-2
Bicomponent conducting yarn

On basis of special dissipating technology and bicomponent yarn spinning technique, DDY features a kind of functional yarn with specific resistance less than 10^41/2.cm. Electric conducting properties result from free electrons inside the yarn so it does not rely on moisture, even under low moisture conditions its conducting performance does not change.
