Filaments— For a long-time functionality and high quality
Soft or hard, fine or strong—Evonik offers the right material for manufacturing filaments.
Evonik’s biobased grade VESTAMID® Terra can be melt spun to create a wide variety of different fiber and filaments products. Each of the polyamides has been and can be adjusted to meet the thermal spinning processing parameters. Depending on the material chosen, the filaments can provide unique technical and sustainable solutions.
In general, the lower water uptake, high chemical resistance and slightly reduced melting point of the VESTAMID® Terra products compared to the short-chain polyamides will lead to lower energy demands in the spinning process, heightened stain resistance and an improved color fastness, as well as an softer touch of the fibers without compromising mechanical properties.
The P84® fibre is a polyimide based fibre with a typical textile character. Polyimides are known to be used in a wide range of operating temperatures starting from cryogenic applications and ending at high temperature applications at the limits of polymer based materials. The thermal stability is based on the aromatic backbone of the polymer. The fibres do not melt. Despite their halogen free structure they exhibit a high LOI of 38%, which means the P84® fibres are classified as non flammable. P84® fibres have a rather unique cross section offering the highest specific surface of all available standard textile fibres.
