The effect of tension in the winding zone of the false-twist-texturing process on the crimp properties of textured polyethylene terephthalate yarn has been investigated. It was found that, all other conditions remaining unchanged, high wind-up tension results in low crimp retraction. Post-texturing treatments enhance the crimp retraction of these yarns and demonstrate the role of wind-up tension in rendering the crimp latent.
