摘要: 不同配比聚对苯二甲酸乙二醇酯(PET)/聚对苯二甲酸丁二醇酯(PBT)共混纤维拉伸结晶、热历史及相容性已有广泛研究.但对不同拉伸比不同配比PET/PBT共混纤维的热行为及力学性能的研究甚少.本文旨在讨论这类性质.

Abstract: The thermal behavior and mechanical property of PET/PBT blend fibers with dif-ferent dravv ratio have been studied.Two independent melting peaks corresponding to that ofpure PET and PBT fiber were observed in DSC curves of blend fibers.Blend fibers of lowdraw ratio showed two Tgs, but only single Tg for that of high draw ratio.The values of ini-tial modulus of the blend fiber possesses an additivity.
