(57) [Summary] [Structure] An aromatic having a tenacity of more than 80 cN / tex and a filament linear density of more than 8 dtex, being soluble in organic solvents and capable of being spun from an isotropic spinning solution. A fiber containing a polyamide as a fiber-forming substance. [Effects] The fiber of the present invention has excellent mechanical properties and thermal properties, is remarkable in terms of high drawability, and can be used in various industrial fields, for example, automobile tires and other rubber products. It can be used as a reinforcement material for reinforcements and the like, in particular for water-curable material reinforcements, as a heat-resistant insulator material for producing filter fabrics, and as an insulation material. |
