Relationship between Viscosity and Recycling of Dendrocalamus giganteus Munro Pulp

Abstract:

In this paper, two groups of Dendrocalamus giganteus Munro pulp were obtained from conventional kraft pulping (the maximum pulping temperature was 165°C) and low-temperature kraft pulping (the maximum pulping temperature was only 135°C) under the premise of kappa number of about 17, and the viscosity of them were 1240 mL•g^-1 and 1426 mL•g^-1 respectively. Then the handsheets was treated with dry heat aging and the simulation of pulp recycling was investigated. In addition, the relationship between the pulp viscosity and recycling times of pulp were studied. The results showed that the viscosity and water retention value of two groups of pulp decreased with increasing of recycling times. However, the recycling characteristic of the pulp with high viscosity from low-temperature kraft cooking was better.
