PROBLEM TO BE SOLVED: To provide spun yarn of spun-dyed meta-type wholly aromatic polyamide fibers, which has low discoloration/fading when exposed to light.SOLUTION: The spun yarn is produced by using a spun-dyed meta-type wholly aromatic polyamide fiber in which a content of a solvent remaining in the fiber is a set level or less. Specifically, the spun yarn is produced by using the spun-dyed meta-type wholly aromatic polyamide fibers in which an amount of the solvent remaining in the fiber is 0.1 mass% or less. |
