Abstract
PURPOSE: To scour polycapramide continuoulsy in a short time, by passing a molded film of specific thickness or less of polycapramide containing the monomer and oligomer through hot water continuouly.
CONSTITUTION: Polycapramide having a relative viscosity of 3.2 (measured in 98% H2SO4 at 1g/100ml and 25°C) and a hot-water soluble content of 11.5% is passed from the continuous polymerization tower 1 to the Tdie to form a film 0.5mm or less thick, e.g. 0.1mm thick and 50cm wide. The film is extruded at a speed of 50m/min continuously, cooled and solidified in the cooling water both 2 at 30°C, passed through the scouring water bath 3 at 95°C during a residence time of 1 min and scoured, then the hot nitrogen gas dryer 4 at 120°C during a residence time of 3 min and dried. The dried film is slit by the slitter 10, cut by the chip cutter 6 into the chips 9. If the film thickness is 0.5mm or more, a long scouring time is required undesirably
