Bally specializes in a wide variety of manufactured fiber types.
Man-made fibers are produced by combining polymers or small molecules. An example of a raw material is petroleum-based chemicals. The typical manufacturing process is as follows:
- Begins as a solid pellet, chip, or flake.
- Heated to its melting point.
- Extruded through a spinneret, like a shower head, and solidifies in the cool air.
- Filaments are stretched and orient into an orderly arrangement. This stretching process gives the filament both its strength and elasticity.
- Multiple filaments are combined into a bundle to form a filament yarn.
- Yarn is graded into deniers (sizes) and used in the weaving, braiding, or knitting of fabric. (A monofilament is extruded as a single filament like a fishing line)
