摘要： A concurrent-biaxially drawn polyvinyl alcohol film is prepared by fabricating a molten hydrate polyvinyl alcohol into a film; drying it under preventing an orientation thereof to form a substantially non-orientated substrate film having a water content of 3 to 20 wt. %; coating an aqueous dispersion of a macromolecular compound on at least one surface of the substrate film to form a coated film having an average water content of 5 to 30 wt. % with an increased water content of 2 to 10 wt. %; concurrent-biaxially drawing the coated film at an area elongation percent of 600 to 1300% to form a drawn film; drying the drawn film under releasing stress at a water content of less than 3 wt. % to form a dried film; and heat-treating continuously the dried film at higher than 160.degree. C. and lower than a decomposition temperature for a short time.

摘要： A carding method in which the rotary flats of a carding machine are driven intermittently so that each time the flats are driven only a portion (1/6 to 1/4) of the flats opposed to the cylinder of the machine are replaced by fresh flats, thereby decreasing the amount of good fibers in the waste, particularly when carding synthetic fibers.The carding machine is provided with a solenoid clutch in the drive mechanism for the rotary flats and the flat cleaning means, and with a timer for controlling the clutch so that the flats can be intermittently driven at desired drive and stop intervals. For carding polyester fiber, the drive interval may be enough to replace one-fifth of the flats opposed to the cylinder of the machine with fresh flats, and the stop interval may be as much as sixty minutes.
