Abstract:

In order to better understand the structure and properties of novel differentiated polyester fiber and provide a reference for subsequent product development. The structures and performances of polyester(PET), polytrimethylene terephthalate(PTT), low viscosity PET and high shrinkage PET cornposite filament(SPH) and PET/PTT composite elastic fiber(T400) were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffractometer, three-dimensional digital microscope, thermogravimetry, etc. The results show that the surface of SPH and T400 fiber have grooves, which can produce capillary effect. After stretching or heat treatment, the SPH fiber can be self-crimped. T400 fiber has large crimp shrinkage, high breaking strength and good elastic recovery. PET has high breaking strength, and can be used as a silk product. The molecular structure of PTT has a unique odd carbon effect, which enables the fiber to have higher resilience and elastic recovery.

Key words: differentiated fiber, polyester fiber, elastic recovery, breaking strength, structure
