Polymer fibers are produced using a process known as polymer spinning, a special type of extrusion. In this production process a spinneret is used to form multiple, continuous filaments. There are four types of polymer spinning: Wet spinning, dry spinning, gel spinning and melt spinning. Melt spinning is used for meltable polymers. This is how a number of fibers such as nylon, olefin, polyester, saran and sulfar are produced.
Thermodynamics, friction, surface wear and electrostatic interaction during the production process have created the demand for ceramic components with high surface qualities such as those offered by CeramTec in material combinations designed especially for thread guides, yarn forming and yarn modification. CeramTec is one of the world’s largest producers of ceramic components for the melt spinning process (and filament spinning).
In addition to “as-fired” and polished surfaces CeramTec also offers TRIBOFIL® and TRIBOSOFT for completely new surface dimensions:
TRIBOFIL® is a special surface for yarn guide elements in applications with low yarn tension and for processing conventional synthetic yarns without any damage whatsoever. This material has been proven in applications worldwide and textile industry experts appreciate its reliability.
TRIBOSOFT is also designed for use in processes at low yarn tensions without any yarn damage. This material is also characterized by long life cycles on both special yarns and raw materials containing aggressive additives such as spun-dyed yarns (SDY), spun-dyed black yarns, CS and bioactive yarns.
