On the visco-elastic properties of paper at super low frequency range

I have studied the visco-elastic properties of paper by vibrating reed method at super low frequency range and I measured, Youngs modulus internal frictional coefficient (viscosity).Youngs modulus and viscosity varies by direction in hand made paper, but Youngs modulus is independent of frequency in the range of low frequency. It reduces as increasing frequency. This viscosity is so-called apparent viscosity so, I will convert it true viscosity by next method let us shearing stressv2lv : frequency, l : length.rate of shear v2l/η I plot v2l, v2l/η I obtain consistency curve.I will regard consistency curve as two kinds straight line.I think this straight line means the true viscosity. Let us those viscosities ηHF (Viscosity at high frequency) ηLF (Viscosity at low frequency). Reasonable solution of these two kinds viscosity ηHEηLFis the problem of future.Youngs modulusEand ηHF, ηLFincrease as reducing its freeness in hand made paper.but increasing process changes by pulp sorts.
