FIELD: chemical industry.
SUBSTANCE: present invention is a fully aromatic polyamide fiber, which is characterized by single thread fineness in the range from 0.4 dtex to 3.5 dtex, a total fineness in the range from 5 dtex to 30 dtex, a tensile strength of 15 cN/dtex or more, an initial tensile modulus in the range from 500 cN/dtex to 750 cN/dtex and a number of fibrils of less than 100/m.
EFFECT: fully aromatic polyamide fiber, which is characterized by a reduced total fineness and a reduced fineness of a single thread and which is also excellent in terms of quality and reinforcement characteristics.
