    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: Polyamide terpolymer compositions, which contain biobased monomers and are suitable for making shaped articles, are disclosed. Comprised of three monomeric species polymerized randomly, including hexamethylene diamine, adipic acid and a bio-based monomer, the compositions are easier to process and have better dye uniformity than polyamides formed from melt-blended biobased components, and are comparable in dyeability, color fastnessand appearance retention performance to non-biobased polyamide copolymers.

    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.
