Non-Wood Fibers: Relationships of Fiber Properties with Pulp Properties

In this investigation, the relationship between fiber properties and papermaking properties of 22 non-wood materials at the unrefined and refined states was assessed. The fiber length had positive and the cell wall thickness had negative correlation on the strength properties for the refined pulp. The relationship between papermaking properties with pulp quality, such as fines, curl index, kink index, external fibrillation, and coarseness, was also determined. The correlations of multiple regression equations of fiber quality parameters were 70.4% for the tensile index and 84.9% for the tear index for the refined pulp. The correlations of multiple regression equations of chemical characteristics of the samples were 81.9% for the pulp yield and 42.7% for the kappa number. Holocellulose and alpha-cellulose had a positive and lignin had a negative effect on the pulp yield.

Automated summary

The study found correlations between fiber properties and papermaking properties, including positive relationships between fiber length and refining pulp strength properties. Multiple regression equations also indicated the relationships between fiber quality parameters and papermaking properties.
