An object of the present invention is to provide a polyamide 56 crimped yarn excellent in dyeing characteristics such as dyeing speed, dark dyeing property, level dyeing property, and dyeing fastness. More specifically, it is to provide a crimped yarn having excellent dyeing properties and excellent heat resistance, wear resistance, mechanical properties, bulkiness, flexibility and durability. SOLUTION: 90 mol% or more of repeating units are made of polyamide 56 composed of pentamethylene adipamide units, the crimp elongation after boiling water treatment is 10 to 40%, and the amino end group concentration is 30. A crimped yarn characterized in that it is -100 eq / ton. [Selection figure] None |
