Synthesis and effects of modified fiber on paper performance

Different fiber materials were modified and the effects of modified fiber on paper performance were evaluated. It's shown that the strength of paper can be promoted by modified fiber. When the mixing ratio of modified NBKP fiber was 5%, the tensile index was increased from 38.28 N.m/g to 47.21 N.m/g. When the addition ratio of modified HYP fiber was 1.5%, the internal bond strength of paper was increased from 49.41 J/m(2) to 55.30 J/m(2), and the tensile index was increased by 48.06%. When the addition ratio of modified fiber of sawdust was 1.5% and mixed with OCC, the tensile index of paper was increased from 18.89N.m/g to 27.55N.m/g, and the ring crush index was increased by 13.99%.
