(57) [Abstract] [PROBLEMS] To provide a method for producing a stain resistant melt-colored carpet fiber which retains a high degree of stain protection even after being treated several times with a high pH shampoo. The composition comprises: a) a polyamide copolymer containing sulfonate groups is melt mixed with a colorant to form a homogeneous polymer melt, b) the polymer melt is spun into fibers, and c) the fibers are Tufting the lining to form a carpet, and d) using this carpet as polymethacrylic acid, a copolymer of polymethacrylic acid, a mixture of polymethacrylic acid and a sulfonated aromatic formaldehyde condensate, and a sulfonated aromatic formaldehyde. Treatment with a compound selected from the group consisting of methacrylic acid polymerization or copolymerization reaction products in the presence of condensates. |
