Dimethylformamide(DMF)is widely used in leather industry, polyacrylonitrile fibrespinning and butadiene extraction craft as an important organic solvent.
Using the acid washing water can reduce pollution and the acidity of the water being drained off in fibrespinning technology. It has obvious economic benefit and social benefit.
