In this study, a facile and environmentally friendly method with low energy consumption for preparing nanoscale AgCl and BaSO4 co-precipitates (AgCl@BaSO4 co-precipitates) was developed based on the metathetical reaction. Then, the dried co-precipitates were melt-compounded with polyamide 6 (PA6) resins at a specified mass ratio in a twin-screw extruder. The results demonstrated that in the absence of any coating agent or carrier, the nanoparticles of AgCl@BaSO4 co-precipitates were homogeneously dispersed in the PA6 matrix. Further analysis showed that after the addition of AgCl@BaSO4 co-precipitates, the antibacterial performance, along with the flame-retardance and anti-dripping characteristics of PA6, was enhanced significantly. In addition, the PA6 composites possessed high spinnability in producing pre-oriented yarn.
