Dedicated specialists in our manufacturing departments continually monitor the production of Twaron®, which is made from monomers in several stages: polymerization, continuous filament yarn spinning and converting.
Step 1: Polymerization
The process begins with the combination of monomers to form a sturdy, finely-grained para-aramid polymer. This material has the typical heat resistance and chemical properties of para-aramid.
Step 2: Continuous filament yarn spinning
Next, the polymer is dissolved in sulfuric acid to create a liquid crystalline solution. The solution is then spun into fine, naturally yellow or dye-infused continuous filament yarns by a wet-spinning process. These fibers are completely crystalline, with molecular chains running parallel to the filament axis, providing the yarns with their unique properties.
Step 3: Converting
In the final stage, the continuous filament yarns are crimped to produce staple fiber, treated with a finishing agent, and then cut to the desired length to create short-cut fibers. The untwisted continuous filament yarns can now also be twisted to enhance their fit-for-use characteristics.
Step 4: Converting to pulp

Filament yarns are chopped and mixed with water to form a fibrous substance called wet pulp. This wet pulp can be sold directly or dried to create and sell as dry pulp.
