Nylon is normally dyed with acid dyes vs. the mordant dyes used for
cotton. The cotton dyes do not work well and I am not sure of
availability of acid dyes to the general public. Acid dyes attach
themselves to the nylon amine end groups.

Chlorine bleach will damage nylon but you might be able to do something
with a peroxide bleach as evidenced here:
