POLYAMIDE FILAMENTS CONTAINING HIGH VISCOSITY ANTISTATIC AGENTS

摘要

Static-resistant polyamide fibers are produced by dispersing from 0.1 to 20 percent by weight of a modified polyalkoxylated hydrogenated castor oil (castor wax) into the polyamide melt prior to filament formation. The modified castor wax is the addition product of castor wax and a diepoxide compound having two ethoxyline groups AS TERMINAL GROUPS. The modified castor wax has a higher melt viscosity than the corresponding unmodified castor wax which enables better dispersion thereof in the polyamide melt. As a result, polyamide fibers containing the modified castor wax are more easily processed and are of higher quality.
