The preparation of flame-retardant poly (ethylene terephthalate) fabric by ionic agent

Abstract

In this paper, PET fabric was modified by the flame retardant HOP to improve flame retardance. The results showed that the flame retardance of PET fabric improved a lot. With the increase of the HOP concentration, the limiting oxygen index could increase to 34%, the horizontal burning length could decrease to 0 mm, the horizontal burning rate could decrease to 0 mm/s, and the vertical ignite time could increase to 5 s. The infrared spectroscopy showed the modification of HOP made PET fabric gain phosphate groups. Moreover, the breaking strength, stiffness and crease recovery angle were kept well.
