This product is an environmentally friendly flame retardant, suitable for permanent flame retardant modification of polyester. The spinnability of the flame retardant polyester obtained is equivalent to that of conventional PET, and can be processed by any spinning system. It has excellent thermal stability, does not decompose during the spinning process, and has no peculiar smell at the spinning site. It can improve the antistatic performance of polyester products and is suitable for various fields where conventional PET can be applied. When copolymerized with PTA and EG, the additive amount is 2.5~4.5%, the phosphorus content of flame-retardant polyester chips is 0.35-0.60%, and the flame retardant oxygen index after spinning fabric is 30~36%.
