    摘要: A method for spinning solution-dyed synthetic fibers from a dope of polymer dissolved in a solvent, which comprises injecting a solution or dispersion of a colorant dissolved or dispersed in a solvent which does not coagulate or precipitate said polymer, into a dope at a spinneret or immediately before it, whereby the colorant is mixed with the dope for uniform coloring.
