【Abstract】 In this paper the PBT/PET blended fiber is studied and its intrinsic viscosity, crystallinity are discussed. It is found that the PBT/PET polyblend shows a good compatibility. Intrinsic viscosity of the blend strengthens with the increment of PBT, PET and PET promote the crystallization each other.更多还原
