Abstract: The use of a sulfonated polyester ionomer resin in a colored, drawn polyamide or polyester fiber results in improved color strength and appearance. Sodium sulfo isophthalate polybutylene terephthalate copolymers when melt blended with synthetic polyamides or polyesters are shown to enhance color strength in drawn fibers. In addition the sulfonated polyesters reduce color strength variation in colored fibers made with different batches of colorant. Water insoluble sulfonated polyester ionomers are preferred.
