PROBLEM TO BE SOLVED: To provide a vinylon fiber having unevenness on a surface and a method for producing the same, and also to provide a carbon nanotube aggregate produced by using the vinylon fiber and a method for producing the same.SOLUTION: The method for producing a vinylon fiber includes a step of fiberizing a spinning dope by a wet spinning method. The spinning dope contains a polyvinyl alcohol-based polymer, a carbon nanotube and water and has a thixotropy index (TI) of 2.1-3.0, which is a ratio of the viscosity at a shear rate of 10(1/sec.) to the viscosity at a shear rate 100(1/sec.) which are measured by using a conic-plane rotational viscosimeter under a condition of temperature 25°C. |
