| Abstract:This paper conducted three recycling processes for US old corrugated container （OCC） 12# and 13# to investigate the variations in the properties of recycled fibers and the mechanical strength of recycled paper as well as the correlation between them. The results showed that US OCC 12# recycled fibers were thicker and longer than US OCC 13#， with higher proportion of fine fibers， and more extensive damage. After three recycling cycles， the fiber length-weighted average of US OCC 12# and US OCC 13# recycled fibers decreased by 10.8% and 15.7%， respectively， while their splitting length ratio increased by 11.2% and 2.3%， respectively. Fiber twisting and bending decreased， whereas fiber breakage increased. The fine fibers content of US OCC 13# recycled fibers progressively decreased， while that of US OCC 12# recycled fibers initially increased and then declined. Following three recycling processes， both recycled paper exhibited reductions in tensile index （12#： 21.4%， 13#： 10.7%） and burst index （12#： 10.2%， 13#： 2.6%）， while their folding endurance increased by 25.6% and 3.2%， respectively. The tear index of US OCC 12# recycled paper increased， whereas that of US OCC 13# recycled paper decreased. Overall， the mechanical strength of US OCC 12# recycled paper was generally better than that of US OCC 13#. Grey relational analysis showed that the proportions of short fibers， fine fibers， and twisted fibers were the key factors affecting paper mechanical strength， primarily acting on fiber bonding interactions. |
