Evonik showcasing high-tech bio-PA fibers at K 2016

Offering a host of benefits, such as maximum wearing comfort and unexcelled performance, the fibers are lightweight, flexible, and breathable. Processed into high-quality fabrics, they have an odor-reducing effect thanks to their lasting natural bacteriostatic characteristics. In addition, they dry quickly and require no ironing. As a result of this range of highly desirable properties, the fibers are suitable for processing in all textile applications, including an Italian designer fabric for evening gowns, functional sporting togs, and durable upholstery materials.

High performance from the castor bean plant
The fibers are produced from Vestamid Terra, a 100% biobased polyamide derived from the seeds of the castor bean plant. Castor bean plants, which can withstand long periods of drought, are cultivated in dry areas which are not suitable for any other form of agriculture. This rules out any competition with arable land that could otherwise be used for food or feed crops. Biopolyamide based on castor beans is therefore both an environmentally-friendly and a sustainable material choice.

The product development process profited from Evonik's technical expertise in the area of high-performance plastics as well as the fiber-processing experience of Fulgar, an Italian fiber manufacturer marketing the biopolyamide fibers under the EVO brand name.

The Vestamid Terra family is comprised of various grades of PA 610, PA 1010, and PA 1012, each of which differ in their profile of properties and close gaps in the previously available range of properties of polyamides. They are long-lasting, durable, and meet the requirements of demanding applications, for example in the automotive, sports, and textile industries. Typical applications of Vestamid Terra products are injection molding, fibers, powders, extrusion, and films.
