How is Technora® produced?
Technora® is produced through a precisely controlled process, closely overseen by dedicated specialists. The production involves polymerization, spinning into continuous filament yarn, and converting into specialized formats such as stretch-broken yarn.
1. Polymerization
Technora® is synthesized from PPD, TDC, and DAPE. The polymerization takes place in a special amide solvent, resulting in a high-performance copolymer. After neutralization, the polymer is ready for spinning. In contrast with standard para-aramids, Technora® contains an additional building block which is incorporated into the polymer structure. This offers a balance of strength, flexibility, and resistance to heat and chemicals.
2. Filament yarn spinning
The polymer is spun directly from the reaction mixture using a unique spinning technology into a water-based coagulation bath. This forms continuous filament yarns with high molecular orientation. The yarns are typically available in natural gold or dope-dyed black/dark grey, with filament diameters around 12 μm. High-temperature aftertreatments further stabilize the fiber structure, enhancing performance across demanding applications.
3. Converting to specialized formats
Technora® can be converted into stretch-broken yarn through a proprietary process that improves flexibility and rubber adhesion. Technora® yarn is also available with tailored finishes to meet specific processing needs across weaving, rubber, and marine applications. It can also be converted into shortcut or staple fiber for use in specialized processes.
Customization of Technora®
Technora® filament yarn is available in various linear densities with optional surface treatments to improve fatigue resistance, chemical bonding, or processing efficiency. These finishing options allow manufacturers to match Technora® precisely to their application requirements.
