Melt extrusion spinning polyamide fibers with sulfonated reagent |
摘要 |
An acid dye stain-resistant fiber-forming polyamide composition comprising a fiber-forming polyamide and a reagent, at least a portion of which associates with free acid dye sites in the polyamide, thereby disabling the acid dye sites in fibers formed from the composition from taking up acid dye stains; a masterbatch concentrate for addition to a fiber-forming polyamide to form an acid dye stain-resistant fiber-forming polyamide composition comprising a carrier compatible with the fiber-forming polyamide combined with an amount of the above reagent in excess of that desired in the acid dye stain-resistant fiber-forming polyamide; as well as fibers and articles of manufacture prepared therefrom.
