Abstract: Dyed yarns typically have inferior color fastness compared with pigmented yarns. However, dyeing offers a virtually infinite selection of colors, flexibility and more uniformity than constructions of pigmented yarns in residential carpet and other yarn applications, such as apparel. It has been found that relatively small amounts of pigment (10 to 1000 ppm) incorporated into polymeric fibers, and particularly nylon fibers used in carpets, creates lightly pigmented yarns which, when overdyed, are highly uniform and have a higher degree of apparent dye light fastness compared to normal dyed yarns. This effect is observable for both anionic and cationic polyamide polymers, and dyeing of these slightly pigmented yarns can be conducted to produce yarns of almost any color of greater depth than the base yarn.

Abstract translation: 与着色纱线相比，染色纱线通常具有较差的色牢度。 然而，与住宅地毯和其他纱线应用（例如服装）中的着色纱线结构相比，染色提供了几乎无限的颜色选择，灵活性和更均匀的选择。 已经发现掺入到聚合物纤维中的相对少量的颜料（10至1000ppm），特别是用于地毯中的尼龙纤维产生轻微着色的纱线，当过度染色时，其高度均匀并且具有更高程度的表观染料光 与普通染色纱线相比具有更高的牢度。 对于阴离子聚合物和阳离子聚酰胺聚合物都可以观察到这种效果，并且可以进行这些稍微着色的纱线的染色以生产比基底纱线更深的任何颜色的纱线。
