| 摘 要： | 本文比较了涤纶长丝的单丝拉伸与复丝拉伸的断裂强度、断裂伸长及分布和初始模量。复丝的峰值断裂强度总是小于单丝断裂强度,但本文提出一种方法,可以通过复丝拉伸试验推得单丝断裂强度。复丝拉伸时,其中单丝的断裂伸长平均值与单丝拉伸时的断裂伸长平均值十分接近。但两者的分布相差很大。复丝的初始模量与单丝的相同。

| Abstract: | The paper studied difference of mechanical properties between single fiber drawing and multifil drawing of PET filament. The breaking strength of a PET filament in single fiber drawing is higher than that in multifil drawing, because the fibers are not broken at the same time in the latter. A new concept - calculating breaking strength of multifil - has been advanced in the paper. Using the concept, we can get breaking strength of single fiber by multifil drawing. The two breaking ratio-elongation distributions are different, but their averages are similar. The two initial moduli are the same, because they are all measured in small deformation. |
