Embodiment 1
[0076] A flame-retardant warp-knitted lace fabric has a flame-retardant limiting oxygen index of 30%, a vertical flammability of UL-94 of V0 level, and a carbon residue of 25% after being calcined at 500°C for 30 minutes.
[0077] Please see attached figure 1 , a production method of flame-retardant warp-knitted lace fabric, which specifically comprises the following steps:
[0078] 1. Preparation of flame retardant polyester masterbatch
[0079] The first step of preparation of the flame retardant modifier is to use trimesic acid and methanol as raw materials, use concentrated sulfuric acid as a catalyst, and carry out esterification reaction at a pressure of 0.25-0.35MPa and a reaction temperature of 105-120°C. After the esterification reaction for 2.5-3.5 hours, the esterified product was obtained. After the esterification reaction, the unreacted methanol was distilled off from the esterified product at 100°C under reduced pressure, and then tribromoneopentyl alcohol was a...
