The Characteristic Behaviour of the Stretch-Orientation Zone during High-Speed PET Spinning**

Jialin Wu, Diaosheng Guan and Baojun Quian

Abstract

A theory is proposed to separate the on-line stress in the stretch-orientation zone during high speed PET spinning into two parts: the thermodynamically equilibrium or quasi-equilibrium stress associated with rubber elasticity and the non-equilibrium driving stress, which leads to coordinated orientation of the macromolecular chains. Precise and simultaneous measurements of the online spinning parameters at five spinning speeds, ranging from 2200 to 4200 m/min, were conducted. A physical model consisting of a dashpot placed in parallel with a Gaussian network was found to describe well the behaviour of the stretch-orientation zone of high speed PET spinning.
