    • Stain-resistant, lightfast nylon carpet is prepared by dyeing cationic-dyeable nylon fibers by applying a print paste containing an acid dye or a premetallized acid dye at a pH of from about 2.0 to about 6-5 and fixing the dye to the fibers, forming the printed nylon fibers into a carpet, applying a print paste containing an acid dye or premetallized acid dye and dyeing the nylon fibers contacted with the print pastes and thereafter heating the dyeladen fibers to fix the dye into the fibers. Stain-resistant lightfast nylon yarns are prepared by printing cationic-dyeable yarn with a premetallized acid dye at a pH of about 4.0 to less than about 6.5 then fixing the dye to the yarn.
    • 通过在约2.0至约6-5的pH下施加含有酸性染料或预金属化的酸性染料的印刷浆料将染料固定在纤维上,对阳离子可染尼龙纤维进行染色来制备抗污,耐光尼龙地毯, 将印刷的尼龙纤维形成地毯,涂布含有酸性染料或预金属化的酸性染料的印刷浆料,并染色与印刷浆料接触的尼龙纤维,然后加热染色纤维将染料固定在纤维中。 通过使用预金属化的酸性染料在约4.0至小于约6.5的pH下印刷阳离子可染色纱线,然后将染料固定到纱线来制备耐污染耐光尼龙纱线。
