re: how about the process of woven bag flat stretch ?

Raw materials into the extruder, the external heating 190-250 ℃ and the screw and the barrel cut each other, the material almost
After all the plasticization, was quantitative, constant pressure extrusion. After the film forming, into a molten film into the cooling water. through
After cooling, the film is cut into embryos by a blade. The embryos are high-power stretched in a hot oven until flattened. The flat yarns are then heat-set on a hot roll, shrunk at low draw speeds, and cold rolls are treated at low temperatures,
Finally by the differential disk tension winding system rolling into shape.
