Application of phosphorus flame retardant ZR-08 to polyester fabric
Flame retardant finishing of polyester fabric is carried out with phosphorus flame retardant ZR-08 by twice-dip-twice-nip method.Through single factor test and orthogonal test,the optimum pro cess is determined:flame retardant ZR-08 280 g/L,pH value 5.5,baking at 195 ℃ for 110 s.The flame retardancy of finished fabric reaches the B1 standard of GB/T 17591-2006 "flame retardant fabric".The finished fabric has good washability,and there is no obvious negative effect on the whiteness and breaking strength.
