Abstract

The invention relates to a production method of a high-quality flame retardant polyester industrial filament. The production method comprises the following steps: drying a flame retardant master batch, accurately weighing and dosing the flame retardant master batch and a high viscosity slice, extruding, fusing, metering, slowly cooling, laterally blowing air to cool, applying oil, drawing and setting through five pairs of rollers, tying an interlaced knot, winding and molding. The product strength (more than or equal to 6.4 cn/dt) is high, and the limit oxygen index LOI (more than or equal to32%) is high.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production method of flame-retardant polyester industrial yarn. Background technique [0002] The limiting oxygen index LOI of polyester is generally 20%-22%, which is a flammable material, and the potential danger caused by fire is becoming increasingly prominent. At present, the flame retardant modification of polyester at home and abroad mainly uses phosphorus-based flame retardants as modifiers (mainly copolymerized with CEPPA). The heat of combustion melts the polyester, reduces the flow viscosity to produce molten dripping, and takes away the heat, and uses the free radical capture effect of the phosphorus-containing flame retardant to extinguish the flame to achieve the purpose of flame retardancy. The flame-retardant mechanism is that the molten droplets take away heat Flame retardant. [0003] There are many studies on flame-retardant polyester in civil ...
