Abstract

Fibers having a tenacity of more than 80 cn/tex and a filament linear density of more than 8 dtex which contain as the fiber-forming material an aromatic polyamide which is soluble in organic solvents and spinnable from isotropic spinning solutions. The fibers can be used for example as reinforcing materials, as heat-resistant insulator materials, for producing filter fabrics or as insulating materials.
