Abstract

A new modified technique of measuring shrinkage forces provides in certain intervals of temperature an alteration of the clamped lengths by a minute stretching or shrinking of the fibres in a manner resulting a zero force deviation. So at each temperature we have an equilibrium of the released inherent stresses of the fibres and the recorded ones. These so called equilibrium-shrinkage-force-curves are capable of describing the state of order of PET-fibres in a better way than other methods do.
