POLYAMIDE FIBER CAPABLE OF HIGH-TEMPERATURE DYEING

The present invention relates to a polyamide fiber which has a single fiber fineness of less than 5 dtex, and has a stress per unit fineness of 0.7 cN/dtex or more in 3% elongation in a tensile test of the fiber, in which a stress F1 in 3% elongation in a tensile test of the fiber before 100°C boili...

description The present invention relates to a polyamide fiber which has a single fiber fineness of less than 5 dtex, and has a stress per unit fineness of 0.7 cN/dtex or more in 3% elongation in a tensile test of the fiber, in which a stress F1 in 3% elongation in a tensile test of the fiber before 100°C boiling water treatment and a stress F2 in 3% elongation in a tensile test of the fiber after the treatment satisfy the following formula (1): F 2 / F 1 > 0.7
