Additive dispersions and process for their incorporation with fiber-forming polymer

摘要

A dispersion is provided for incorporation with a synthetic fiber-forming polymer. The dispersion comprises a polymer additive having an average diameter of up to 50 microns at a temperature of 25 DEG C., a carrier, and a thickener selected from the group consisting of dibenzylidene sorbitol and silica having an ultimate particle size of 7 to 14 nanometers.
