Abstract
PURPOSE: To enhance the binder-fixing property of plant fibers and produce the fiber board excellent in bending strength by a method wherein a polyvinyl alcohol resin containing specified amine cationic groups is used as a binder.
CONSTITUTION: The polyvinyl alcohol resin containing 0.1W10mol% of at least one of the cationic groups of the formuulas (where R1 is alkylene or hydroxyalkylene; R2 and R6 are hydrogen or alkyl; R3 and R4 are alkyl; X is inorganic anion; A is amide nitrogen or oxygen) is added into a dispersion of the plant fibers and the board is prepared from the dispersion. Since the specified resin is used as a binder, the fixation property of the binder to the fibers is enhanced, the COD load of filtrate is reduced, and the bonding strength between the fibers and the bending strength of the board are enhanced. In addition, flocculating performance of the fibers is high, resulting in an enhanced yield.
