Abstract

Polyester fiber can be dyed with indigo so as to possess washdown and fading characteristics similar to indigo-dyed cotton fibers provided they are first coated with a polymeric salt having the following repeating units: ##STR1## with from 0 to 75 mol % of another ethylenically unsaturated monomeric unit,
or ##STR2## wherein R is hydrogen, methyl or ethyl
R1 is a divalent hydrocarbon radical of 1 to 4 C atoms
R2 and R3 are lower alkyl (from 1 to 4 C atoms)
R4 is hydrogen, hydroxyethyl or lower alkyl (from 1 to 4 C atoms)
X- is an anion
Preferably, in Formula A, R1 contains 2 carbon atoms; R2 ═R3 ═R4 ═methyl; and X- is 83 mol % CH3 SO4 -- and 17 mol % C18 H35 SO4 --.
