ABSTRACT:
A process for preparing melt spun polymeric fiber made from polymerized amide monomers includes the steps of pigmenting the polymer, incorporating within the polymer sufficient SO.sub.3 H groups or salts thereof to give the polymer a sulphur content of between about 10 and about 160 equivalents per 10.sup.6 grams polymer and thereafter chemically blocking with a chemical blocking agent a portion of amino end groups present in the sulphonated polymer.
