After refining at a pulp consistency of 10% with 30 oOO rin aPFI refiner，when the proportion of noil fibers reached 40% ，the mechanical properties of the paper produced by blending were significantly enhanced，showing a tear index of 10.2mN⋅m2/g ，a folding endurance of 1O6 times，a burst index of 1.26kPa⋅m2/g ，and a tensile index of 46.2N⋅m/g ： Key words：industrial hemp noil fibers；ultrasonic；bio-composite enzyme;kraft pulping
