Abstract: Halogen-free flame-retardant PA6 is a polymer obtained by modifying conventional PA6 and is suitable for processing into flame-retardant fiber. This paper compared the rheological behavior of halogen-free flame-retardant PA6 and conventional PA6, and found that halogen-free flame-retardant PA6 has a lower apparent viscosity than the conventional PA6, and is more sensitive to shearing force and thermo condition than conventional PA6. The authors put forward that during the processing of halogenfree flame-retardant PA6 fiber, its technological parameters should be controlled more strictly.

Key words: halogen-free flame-retardant PA6; rheological behavior; fiber processing
