▎ 摘　　要

NOVELTY - Antistatic polyester fiber with high and low temperature melting temperature comprises polyester fibers (A) with low melting point and polyester fiber (B) with high melting point conductive system, where the melting temperature of the first fiber is lower than the melting point of the second fiber, and the first and second fiber are respectively provided with multiple parts. USE - Antistatic polyester fiber used in filter material (claimed) and antistatic material. Can also be used in automotive filter material. ADVANTAGE - The antistatic special polyester fiber has high and low temperature melting temperature. The conductive path is established in the filter material, the conductivity is improved, the surface resistivity is greatly reduced, and the antistatic purpose is realized.
