The PAR-TEC 100, a particle size analyzer manufactured by Lasentec, Inc., is being evaluated as a sensor for in-line monitoring of fiber development during refining. The approach used is to beat softwood pulp in a Valley beater to produce a three point beater curve and to compare PAR-TEC measurements on those samples with Canadian Standard Freeness, Kajaani fiber length and coarseness, as well as tensile, wet tensile and tear strength. There is a very good positive correlation between PAR-TEC 100 scan counts mean size and tensile index; and a strong negative correlation to Canadian standard freeness, and Kajaani fiber length when evaluating Valley beater fiber development. There is a positive relation between the results of analyzing the individual Bauer-McNett fiber fractions with both the Kajaani 100 and PAR-TEC 100. These results indicate that the PAR-TEC 100 measures a complex value of fiber size, which under the correct circumstances is directly related to Kajaani arithmetic average fiber length. 16 figs.
