Relationship between “Characteristic form of Filtration” and filtered particles is explained, and the derivation of this relationship is studied in the case of constant rate filtration test. The obtained results are as follows. (log P/P0)/t=C•K-C/2•K2•t where C=1/n'(1-n) n': structural viscosity coefficient of filtered solution n: index of characteristic form _??_ (_??_=dR/dV=KRn) P: filtration pressure P0: initial filtration pressure t: filtration time K: filtration constant n indicates the relative size of filtered particles to the hole of filter media, and K indicates the number of particles and the whole filtration obstruction is measured by C•K which includes the effect of both size and number of filtered particles.
The experimental results of constant rate filtration test for viscose are in good agreement with the above equation. Further, the values of n, K, C•K are compared with microscopic observation of undissolved fibers in viscose.
