Uniaxially oriented polymer filament with macroscopic cylindrical symmetry, in which the average direction of the polymer chain axis coincides with the cylindrical symmetry axis.
Notes:
- A crystalline polymer fiber generally consists of lamellar crystals or fringed micelle-type crystals (see fringed micelle model) with an interconnecting amorphous phase, or, rarely, of extended-chain crystals.
- The cylindrical symmetry shown by crystalline polymer fibers is not at the molecular scale but results from the random orientation of crystallites around the axis of the fiber.
