    Abstract: A synthetic polymer composition comprising a blend of a synthetic thermoplastic polymer and a polymer containing a polyether chain as a constituent, wherein the article manufactured from the blend contains an active compound is disclosed. Yarns may be formed from the synthetic polymer blend and then knitted or woven into articles, such as net or fabric. The articles may be treated with active compounds such as a perfume, fabric softener, sunscreen agent, antibacterial agent, pesticide, insecticide and such other compounds that provide functionality on the article. The treated articles of the invention retain more than an effective amount of active compounds even after numerous washings.

    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: 与着色纱相比，染色纱通常具有较差的色牢度。 然而，染色提供了几乎无限选择的颜色，柔韧性和更均匀的颜色纱线在住宅地毯和其他纱线应用（如服装）中的构造。 已经发现，掺入聚合物纤维中的相对少量的颜料（10-1000ppm），特别是用于地毯中的尼龙纤维，产生了轻度着色的纱线，当被覆盖时，它们是高度均匀的并具有较高程度的表观染料光 坚牢度与普通染色纱相比。 这种效果对于阴离子和阳离子聚酰胺聚合物都是可观察到的，并且可以进行这些轻微着色的纱线的染色以产生几乎比基础纱线更深的任何颜色的纱线。
