Study on Influence of Crimping Performance of PET/PTT Self-Crimp Yarn Treated with Moist Heat
PET/PTT conjugate yarn has a three-dimension spiral and permanent crimp, which endow the yarn and loomage with excellent performances of crimp extension and crimp recovery. The residual deformation and internal stress of the self-crimp yarn can be eliminated after the moist heat treatment, in order to develop the favorable crimp extension and crimp recovery of the self-crimp yarn, and to give the loomage soft handle and good dimension stability. Crimp shrinkage, crimp module, etc, of the different types of PET/PTT yarn, were tested, and the axial morphology of the yarn was observed, to investigate the effect of linear density, moist heat temperature on PET/PTT yarn.
