Structure and Properties of MWNTs-OH/PET FDY Composite Fiber

Abstract:

The MWNTs-OH/PET composite fibers were prepared by the masterbatch melt blending spinning drawing one-step process (FDY), and the structure and properties of different contents of MWNTs-OH of the PET FDY fiber were studied. The results showed that the interaction between MWNTs-OH and PET matrix was enhanced after the modification of terephthalic acid (TPA), resulting in the improved interface compatibility. Also, the crystallinity of the composite fibers was raised 7% after the addition of modified MWNTs-OH. The fracture strength of composite fibers had firstly increased and then decreased with increasing of the content of MWNTs-OH, the strength of the composite fiber was largely improved by 60.5% with 0.2% (wt) of TPA/MWNTs-OH.
