BENCHMARKING PAPER MACHINE INFLUENCE ON LINTING AND PILING

A wide range of Canadian newsprint machines were surveyed for their linting propensity using the long-established FPInnovations Lint Test (formerly the Paprican Lint Test) for image area linting and the newly developed LP (Linting and Piling) Test for non-image area linting. Results showed that although overall linting performance has been improved, there are significant differences among paper machines. A closer examination of paper machine configuration showed that linting is affected strongly by the former type, as well as by the degree of consolidation in the press section. This was especially evident for cases where similar pulp furnish is supplied to very different machines in the same mill.
