NOVELTY - The fabric base fiber has in which tetrafluoroisophthalic acid, N,N'- Add bis(2-hydroxyethyl)oxalamide and catalyst re added into the polymerization reactor, stirred, the pressure is adjusted to 0.4-0.6MPa. The 2,4-diaminobenzenesulfonic acid, dicyclohexylcarbodiimide, 4- Dimethylaminopyridine are addded, the reaction is stirred for 4-6 hours under nitrogen or inert gas atmosphere at 130-150 degrees C, then the product is washed for 3-5 times with ethanol, and then placed in a vacuum drying oven at 85-95 degrees C to dry to constant weight. The polycondensate and chloride (1-butyl-3-methylimidazole) are added to water, stirred at 50-60?0C for 8-10 hours, taken out and washed with water 3-5 times, revolved and evaporated to remove water to obtain ion-exchanged polycondensate. The ion-exchanged polycondensate prepared is fed into a screw extruder for extrusion, and then wet-spinned to prepare modified fluorophenyl oxamide-based polyester fiber. USE - Antibacterial flame-retardant waterproof fabric base fiber. ADVANTAGE - The antibacterial inflaming retarding waterproof fabric base material fiber has excellent flame-retardant and fire-resistant heat insulation effect and is configure to introduce hydrophilic sulfonate structure on the molecular chain, with good water resistance and air permeability, introducing imidazole salt structure by ion exchange, improving the antibacterial property and flame-retardant weather resistance of the cloth.
