specific Embodiment
[0019] The superabsorbent fiber is prepared by using the production device of the present invention.
[0020] The long filament bundles of polyacrylonitrile semi-finished fibers are used as raw filaments, and after being sorted by the tow finishing machine 1, the filament bundle fibers with evenly distributed tension enter the hydrolysis reactor 2, and the filament bundles to be hydrolyzed reciprocate in the tow The 21 upper godet rollers 221 and the 20 lower godet rollers 221' of the frame 22 are reciprocally wound up and down to prolong the reaction time reasonably; after the temperature in the hydrolysis reactor 2 is 90-95°C, the NaOH concentration is 150410g / After reacting in the bath liquid of L for 50-60min, then pass through the first squeezer 3, the first washing tank 4, the second squeezing machine 5, the pickling tank 6, the third squeezing machine 7, the second washing tank 8, the After four squeezers 9, dryers 10, cutters 11 and balers 12, the product high water-a...
