Effects of Latency Removal on the Fiber Properties of Poplar APMP

Abstract:

The refining is the important stage in the APMP pulping process, and high temperature pulses generated in this stage make pulp fibers stiff and ankylosis, which can reduce the strength properties of the pulp. Latency removal is the best way to modify pulp fibers properties and improve their strength. This study focused on the effect of latency removal on the properties of the poplar APMP pulp. atency removal can improve effectively the physical properties of the APMP pulp,the breaking length of the latency removal pulp increased 3.06%, burst index increased 1.97%, tear index decreased 6.07%, and brightness increased by 0.38%ISO.in the 60°C. the breaking length of the latency removal pulp increased 11.80%, burst index increased 14.30%, tear index decreased 6.63%, and brightness increased by 0.77%ISO in the 80°C.
