    Abstract: The present invention relates to a bi-component antistatic fiber produced by means of a conjugant / melt extrusion spinning process where the fiber comprises TiO 2 and nylon with carbon black as the conductive component of the fiber. At TiO 2 loadings in the range of 20-30% by weight, the TiO2 camouflaged the normally black surface carbon stripes, and the resultant light colored yarn was comparable in conductivity to darker yams. The resulting yam is suitable for use in light colored apparel, especially where certain surface resistance levels are required in light colored fabrics.

    Abstract: A customizable polyamide polymer, in particular Nylon 66, Nylon 6, and copolyamides, having a high molecular weight, excellent color, and low gel content is disclosed. In particular, disclosed is a polymer having a relative viscosity greater than 50 as measured in a 90% strength formic acid solution; consistent viscosity with a standard deviation of less than 1; a gel content no greater than 50 ppm as measured by insolubles larger than 10 micron; an optical defect content of less than 2,000 parts per million (ppm) as measured by optical control system (OCS). The polymer can be made into monofilaments or a multifilament yarn. Also disclosed is a process of producing the polymer using in-line vacuum finishing technology in the absence of steam or other gases in the second, or post condensation, step of the polymer process.
