Antistatic type composite flame retardant fiber and preparation method thereof

The invention provides antistatic flame retardant fiber and preparation method thereof. The cross section of the fiber is a sheath-core structure; a sheath layer contains conductive powder and halogen-free flame-retardant polyamide 6; a core layer is polyester, the polyamide 6 or a polyamide 66, wherein the weight ratio of the sheath layer to the core layer is (15:85) to (25:75), and the conductive powder accounts for 5-7% of the total mass of the sheath layer. Since conductive power is added in the halogen-free flame-retardant polyamide 6, so that the fiber is endowed with the antistatic function and the flame-retardant function, particularly the electrostatic absorption of dust, caused by fiber, can be reduced because of anti-static function, and then the cleanness and favorable cleanable performance of a fiber product can be kept; and meanwhile the fiber with the sheath-core structure can still keep favorable mechanical properties and spinning property. While keeping better antistatic and flame-retardant properties and mechanical properties, the fiber reduces the production cost and improves the processing properties, thereby being more user-friendly for downstream users.
