摘要：
A fiber-forming polyamide composition contains a fiber forming polyamide and a sulfonated polyester concentrate, the concentrate disabling and dye sites in the polyamide so that fibers formed from the composition will have enhanced stain and soil resistance. The sulfonated polyester concentrate contains a reagent, preferably an alkali metal salt of 5-sulfoisophthalic acid, and thermoplastic polyester, preferably one or more of PET, PTT, PBT, PETG and poly(ethylene terephthalate-co-isophthalate).
