摘　　要：研究了ＰＢＴ／ＰＥＴ共混纤维结构和拉伸、染色性能的关系．实验结果表明．随着ＰＳＴ／ＰＥＴ共混比的增加，初生纤维的结晶度、取向度及纤维的断裂强度、上染率均增加．而断裂伸长下降，纤维经拉伸定形后．结构和住能有较大的变化．In this article the relation between structure of PET/PET blend fiber and its properties of drawingand dyeing has been studied.It was showed that as the rate of PBT/PET content incr ease, change in both the structure andproperties of PBT/PET as-spun fibers occur, such as, as ths crystallinity and orjentution of fibers in- crease, the breaking strength and dye-uptake of fibers increase, but its breaking extension decrease.A fier as-spun fibers drawing and setting, there are great change in structure and ptopertis of PBT/PET fibers.
