An examination of the effect of the false‐twist process on structure and dyeing behavior of Terylene is described. It was found that if dyed without tension, textured yarns had a higher rate of dyeing than when dyed under tension. However, the textured yarns dyed under tension had a lower rate of dyeing than corresponding flat yarns prepared without the application of the false‐twist process. An explanation of these results is given in terms of a structure that on heating leads to a higher lateral order of the morphologic units and thence to an increased formation of voids, but superimposed on which is a system of gross elongated cracks brought about by the false‐twist process.
