Abstract
A liquid-crystal polyether fiber with high tensile strength has an ash content of 0.3 percent by weight or less, a degree of fusion (f) of 3 or less, and a tensile strength of 18 cN/dtex or more. The liquid-crystal polyether fiber has few residues of an anti-fusion agent and causes no fusion between filaments.
