<p>Polyamide fibers formed by melt-spinning wthout the higher mel viscosities a nd not limiting the extent and rate of polymerization, not hindering the discharge of the melt from the reactor, and eliminating excessive foaming during melt polymerization characterisitic of polyamide fibers derived from sulfonate-containing monomers are obtained from a composition including a fiber-forming polyamide and a concentrate having one or more sulfonated aromatic acid reagents in a thermoplastic carrier resin such as a polyamide or a polyester.</p> |
