How is Twaron® produced?
Dedicated specialists closely oversee Twaron® production, a three-stage process: polymerization, spinning into continuous filament yarn, and converting.
1. Polymerization
In the first stage, monomers are combined to form a robust, fine-grained para-aramid polymer, known for its heat resistance and chemical resilience. This fine powder improves the quality of the plastic components. However, at this point, it does not possess the unique mechanical properties of yarn or pulp.
2. Continuous filament yarn spinning In the second stage, we dissolve the polymer in sulfuric acid, creating a liquid crystalline solution. This solution spins into fine, natural yellow or dope-dyed black yarns. Typically, each filament measures as thin as 12 μm in diameter. These yarns boast a 100% paracrystalline structure, with molecular chains aligned parallel to the filament axis. This precise orientation is key to the remarkable properties of Twaron® yarns.
3. Converting to staple and short-cut fiber To create Twaron® staple fiber, we crimp the continuous filament yarns, applying a finishing agent if needed. After drying, yarns are cut to the desired length.
Converting to pulp
To make Twaron® pulp, we cut the filament yarns, then suspend and fibrillate them in water. The pulp is marketed as wet pulp or dehydrated and dried for sale as dry pulp.
Customization of Twaron®
We offer further customization of Twaron® continuous filament yarns, including high linear densities tailored to client needs. We can apply additional functional coatings to improve product utility. Moreover, untwisted yarns can be twisted to meet specific application requirements, optimizing performance.
