摘要： A shaped article is disclosed which is formed from a polymer mixture of polyamide polymer, pigment dispersed in a polymeric carrier and about one-half to nine percent free polyester based on the weight of the polymer mixture. A process for making the shaped article is also disclosed, wherein the polymer mixture is melted, mixed and formed into the shaped article. The invention is especially suited for use in forming multifilament yarn, where the use of the invention facilitates the spinning of yarns containing difficult-to-spin pigments. The invention may be advantageously employed using conventional polyamide melt-spinning techniques.

摘要： Disclosed are spray-on anti-soil formulations, and methods for treating fibers, carpets, and fabrics with the same. The anti-soil formulations comprise a synergistic blend of an anti-soil component and a stain blocker component adapted to be sprayed-on a fiber, carpet, or fabric instead of known exhaust applications. The anti-soil component can be either fluorochemical or non-fluorochemical based, while the stain blocker can comprise any chemical that blocks positively charged dye sites. Fibers, carpets, and fabrics treated with the anti-soil formulations exhibit superior anti-soil characteristics compared to sprayed-on fluorochemicals and exhibit similar anti-soil characteristics compared to known exhaust application.

摘要： 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.
摘要翻译：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。
