Super engineering plastic fiber/ fiber structure


Long fibers of super engineering plastic resin made by Gunze’s unique spinning techniques.

It could be used as filament or processed goods such as net mesh, brush, pile, etc., and be used in a variety of applications from industrial materials field to high-tech field.

Application Examples

Net mesh-shaped, short fiber/pile, braided tubing, brush-shaped, braid/cover ring, ribbon-shaped, bag-shaped, roll-shaped.
