Abstract

The change in yarn tension has been calculated theoretically as a function of the precipitant concentration in the precipitation bath. For the investigated system (polyoxadiazole), the calculated range in change of tension on transition from mild to severe spinning conditions is 0.45×10-4<F<0.58×10-3 N (under conditions of constant rate of take-up). It has been shown that under severe spinning regimes the assigned rate of take-up is attained immediately on exit from the spinneret channel. The effect of yarn tension on expansion (compression) of the polymer jet after exit from the channel has been qualitatively investigated. For polyoxadiazole, the coefficient of jet expansion (compression) varies within the range 0.53<B*<1.77, depending on F.
