| Abstract: | The Internal causes of latent - crimp were analyzed by studying the supermolecular structures of the standard polyester fibers (PET), copolyester fibers (IPET) and their side - by - side composite fibers (PET/IPET) in this paper. It is concluded that IPET and PET/EPET have better latent - crimp ability because of their asymmetric supermolecular structures. At the same time, they have good dyeability and mechanical properties. So It is a simple and low cost process to manufacture latent - crimp continuous fibers by melt - spinning of the copolyester IPET. |
