Temperature rise of spinning melting production line before operation

　　Before the spunbond and melt blown nonwovens production line is put into operation, the spunbond and melt blown systems start to heat up from the cold state respectively, including screw extruder, melt filter, melt pipe, spinning pump, spinning box and other equipment, and all kinds of auxiliary equipment, such as cooling water system, compressed air system, etc., should be in normal working state. It should be noted that during the temperature rise of melt blown system, the spinning system should be in the off-line position.
