The product prepared by the method has an excellent flameretardant function.

The invention relates to a chinlon monofilament with a bending-resistance and wear-resistance composite function. The chinlon monofilament is characterized in that component raw materials of the chinlon monofilament comprise, by mass percent, 5%-10% of composite function master batches and the balance nylon particles; the number of times of bending resistance of the chinlon monofilament ranges from 50,000 to 90,000; and in the flame retardance performance of the chinlon monofilament, the limit oxygen index LOI ranges from 30% to 40%, and UL-94 is level V-0. Adding of nanometer titania and nano-zinc oxide is mainly used for overcoming the defects that the sunproof and light resistance performance of nylon wires is poor, and therefore light resistance is improved; adding of a fire retardantis mainly used for improving the fire retardant function of the nylon monofilament; and adding of nano barium sulfate is mainly used for improving wear resistance, and therefore wear resistance and bending resistance of a product are finally improved.
