Some attempts were made for standardized representation of pulp fiber classifying results.
On H.S. type fiber classifier, log plots of residual fractions versus shieving time indicated rapid falling at the start and subsequent slower linear decrease (Fig. 1), though theire declination varies with the sample, wire mesh, and other shieving conditions.
Thus, it can be regarded as the process consists of two parts; one depends on relatively shorter fiber fraction, and the other represents the behavior of longer or impassable fraction.
Each part was represented by equation in which the passing probability was assumed semiempirically.
Through fitting their solutions with experimental data, the percentages of impassable fractions were estimated. For several samples, these estimated values indicated monoclinic decrease with increasing mesh-opening.
