Durable flame-retardant finish of polyester used for curtain fabric
Organic phosphorus flame retardant Jintenyl DFR is used for durable flame retardant finishing of polyester fabric.The effects of flame retardant concentrations,baking temperature,baking time and pH value on flame retardance are studied.The optimum process is Jintenyl DFR 200 g/L,penetrating agent JFC 1 g/L,pH value 5.5,drying at 100 ℃C for 180 s,baking at 195 ℃ for 65 s.The results show that the flame retardant performance of polyester fabric after several washing is durable.
