Flame retardancy of polyamide 6 hybrid fibers: Combined effects of α-zirconium phosphate and ammonium sulfamate

The synergistic effect was found between α-zirconium phosphate (α-ZrP) and ammonium sulfamate (AS) for enhancing flame retardant properties of PA6/AS/α-ZrP composites. Moreover, above mention composites have been successfully used in the field of melt-spinning fiber, and the tensile strength and elongation at break of PA6/AS/α-ZrP fiber reached to 1.9±0.07 cN/dtex and 70.4±3.45%, respectively.192
