Abstract:The developed two-dimensional dry spinning model together with a die swell subroutine supplied by an industrial company has been used to generate predictions, which were compared to experimental data. Based on the analysis of the predictions and comparisons, we learn that phase separation cannot occur during dry spinning because the solvent concentration path does not cross over the binodal curve; instead, it passes into the homogeneous glass transition region. Model predictions were compared with concentration data for different DPF (denier per fiber) fibers and fairly good agreement is acquired by tuning the prefactors in the phenomenological diffusion coefficients. It is also suggested that more systematic diffusion coefficient measurements are needed. (Abstract shortened by UMI.).
