The rheological characteristics (complex viscosity, equilibrium relaxation time, equilibrium shear modulus) of a viscoelastic spinning solution obtained in a viscometer and under actual fiber-spinning conditions are examined. It is shown that the optimal regimes for spinning stronger fibers could be predicted by using the spinning-solution rheological characteristics and correlation coefficients obtained in a viscometer.
