Abstract

The effect of the intrinsic viscosity and concentration of polymer in LC solution on the mechanical properties of PPBT yarn was demonstrated. In examining the spinning stability of PPBT yarns, use of spinnerets with an opening diameter of 0.25 mm and conditions ensuring cooling of the jets of heated LC solutions in an air gap are preferred. The isometric conditions of drawing of jets of a LC solution of PPBT with a ratio greater than 7–8 initiate one-dimensional flow with stable pulsation of the diameter. The phenomenon is known as draw resonance.
