Flame retardant spun polyethylene yarn
Phosphorus-containing compounds are used as comonomers to make copolymers with dimethyl terephthalate and ethylene glycol through ester exchange and polycondensation, and then phosphorus-based flame-retardant polyester staple fibers are made through melt spinning, stretching and other processes. This method connects the flame-retardant structural unit to the macromolecular chain, which has permanent flame retardancy., flame retardant polyester fibers contain 6500 ppm of phosphorus, with an LOI of ≥32Related Applications
