Papermaking properties of pulp This section describes the laboratory testing procedures for papermaking pulps. The testing has two categories: testing the quality properties of a specific pulp and comparing the papermaking potential of different pulps. The idea of traditional laboratory testing of pulp is to simulate the papermaking process in the laboratory in a standardised

Papermaking properties of pulp
After reading this article you will..
- understand that pulp quality has no general definition. It always depends on the end purpose, e.g., paper grade.
- know that testing paper properties from laboratory sheets is still important as predicting paper quality from single fibre properties is difficult.
