Abstract: Circular knit, elastic fabrics (10) of at least one of single jersey, French terry, and fleece are disclosed that include a bare elastomeric material (12) plated with spun and/or continuous filament hard yarns (14) . The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 2.5x its original length when knitting to form the circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece.

Abstract: A polymeric, phosphorus-containing composition made by heating, in the presence of an initiator, preferably a free radical initiator, and optionally in the presence of one or more comonomers, at least one ethylenically substituted phosphonylated 2,2'-dihydroxyl-1,1'-binaphthalene or at least one ethylenically substituted 2,2'-dihydroxyl-1,1'-biphenylene.
These polymers may be combined with a group VIII metal to form catalysts for hydrocyanation, hydroformylation or unsaturated nitrile isomerization.

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: Included is a spinning cell for a synthetic fiber such as spandex. The spinning cell includes a top closure which reduces or eliminates solvent vapor transfer, where solvent vapor process gas(es) may leave the cell and room air may be introduced into the spinning cell. A bottom closure device may also be included.
