Abstract:

In order to fabricate the composite fibers with excellent elastic and soft touch, the polyether-ester (TPEE) and polybutylene terephthalate (PBT) were used to fabricate the side by side bicomponent fibers. The effect of the rheological behavior and composition ratio of the TPEE and PBT component on the spinnability was studied. Meanwhile, the mechanism of crimp formation within the composite fibers was analyzed. The results show that the addition of TPEE can reduce the elastic modulus of the composite fiber, and which is contribute to the flexibility of the composite fibers, but it is unfavorable for the improvement to the breaking strength of the fibers. When the volume ratio of TPEE and PBT component is 5∶5, the breaking strength and elastic modulus of the composite fibers is 1.4 and 13 cN/dtex, respectively, and the curl ratio is as high as 80%. The crimp mechanism of TPEE/PBT composite fibers can be explained that the thermal shrinkage of TPEE component is much lager than that of PBT component, so that the shrinkage of TPEE component is easily hindered by the PBT component during the fiber forming process and the crimp forms.
