Abstract: This invention relates to polyester compositions useful for the manufacturing containers that minimizes the effect of secondary contamination during filling. More specifically, the present invention relates to a polyester bottle for use in filling of carbonated pasteurized products comprising at least one oxygen scavenging component that limits oxygen ingress to about 1 ppm or less when measured six months after filling, and at least one passive component that limits the carbonation loss to less than about 25 % when measured six months after filing. The present invention also relates to a method of using the polyester bottle to minimize the growth of secondary contaminants in a carbonated pasteurized product.

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: Commercially acceptable spandex can be prepared with greater efficiency, improved consistency and at lower costs from a high-solids content polyurethaneurea polymer solution. The polyurethaneurea is prepared using a combination of 4, 4'-MDI and 2,4'-MDI, and an amount of chain extenders and chain terminators such that the polymer solution, prior to spinning, is highly soluble and has an appropriate pre-spun IV and primary amine content.
