<p>An acid dye stain-resistant fiber-forming composition and a masterbatch concentrate containing a compatible carrier is prepared to obtain fibers for which the feedstock is easier to form, allows different levels of stain resistant reagent to be easily added so that the composition can be formulated for optimum stain resistance requirements influenced by the chosen fiber color, easier drying and prevention of the removal of the stain resistant property characteristic of coating with sulfonate-containing materials. The composition and masterbatch concentrate contains a reagent such as a 5-sulfoisophthalic acid (salt), a portion of which associates with free acid dye sites in the polyamide, thereby disabling them from taking up acid dye stains.</p> |
