ABSTRACT:
A process for preparing a nylon 66/6 copolymer fiber with reduced spherulites comprising adding 1-6% caprolactam and 0.001-2% water-soluble inorganic calcium salt to 94-99% nylon 66 salt to form a nylon 66/6 salt solution, polymerizing the salt solution to form a polymer, and extruding the polymer.
