Pulp and Paper Properties Affecting the Linting Propensity of Paper: Fundamentals

Little is known on the pulp and paper properties controlling the fibre removal in a printing nip, source of linting in offset printing. The linting propensity of pulps and papers was studied by printing on British handsheets made of different combinations of thermo-mechanical pulp, stone groundwood, and low yield sulphite. The linting propensity tests used where the IGT pick test, the Varkaus method, modified and not, and the number, cumulated length, and distribution of fibers removed while printing at different speeds on a laboratory printing press. Fundamental relationship between some pulp properties such as specific surface of fibers and bond strength, and paper structural parameters such as porosity are proposed and the linting propensity of pulps and paper are proposed. It is found that the relationship are not only non-linear in nature but should include both pulp and paper properties. propensity of pulps and paper are proposed.
