Synopsis

T h e viscous forces acting on a DNA macromolecule in a fiber are calculated. T h e DNA polymer is modeled as a n infinite rod of elliptical cross section with a grooved surface. T h e viscous solvent is hydrodynamic water. Appropriate boundary conditions for determining the viscous forces on the acoustic vibrational modes are discussed. The viscous forces acting on each mode are then calculated as functions of both frequency and amount of water in the fiber. T h e mass loading of the DNA due to water in the grooves is shown to reduce the longitudinal acoustic velocity, which agrees with recent experimental results. The longitudinal modes are determined to be underdamped and correspondingly sharp over a range of frequencies and humidities appropriate to experimental conditions. T h e torsional and transverse acoustic modes are still strongly overdamped.

Modeling results indicate that a moderate increase in coarseness of the initial dispersion of the polymer in solution leads to a faster coagulation rate and to the formation of a more uniform structure. Such an increase in coarseness can be obtained either by bringing the polymer solution close to t

## Abstract Our previous work showed that drawing polyamide 66 (PA 66) fibers at room temperature does not change the degree of crystallinity, but only increases the molecular orientation. We therefore have used a series PA 66 fibers with different draw ratios to establish a direct correlation betw
