Abstract
A process for producing hollow polyamide filaments having at least one continuous void that adds to a fiber-forming polyamide from about 0.05% to about 5% of a triazine compound prior to extrusion of fiber. The process results in a greater closure of voids and larger void space than when the triazine compound is not used.
