An antistatic polymer monofilament of this invention comprises a polymer composite of a thermoplastic polymer as a matrix and carbon nanotubes as a conductive filler. A process of this invention for manufacturing an antistatic polymer monofilament comprising the steps of blending in an extruder a thermoplastic polymer and carbon nanotubes and extruding monofilaments from said blend. An industrial fabric of this invention, which is usable in nonwoven and papermaking machines, said fabric comprising monofilaments for dissipating static charges, said monofilaments including a thermoplastic polymer matrix and a filler of carbon nanotubes.
An antistatic polymer monofilament comprising a polymer composite of (a) a thermoplastic polymer as a matrix and (b) carbon nanotubes as a conductive filler, said monofilament having a diameter between 0.1 mm to 1.0 mm, a surface resistivity between 104 to 109 ohms/square, a static dissipation rate less than 200 μs, a tensile tenacity greater than 1.5 g/d and a tensile elongation at break greater than 20%.
