摘要
测试了各种不同规格的有色涤纶牵伸丝主要性能 ,并研究了拉伸倍数对牵伸丝力学性能和热收缩性能的影响规律。研究结果表明 :牵伸丝的断裂强度与拉伸倍数呈线性相关 ,断裂伸长率与拉伸倍数呈对数双曲线规律变化 ,沸水收缩率与拉伸倍数呈抛物线规律变化。
The main properties of colored PET drawn yarn of various specifications were determined. The effects of stretching ratio on mechanical properties and hot shrinkage of drawn yarn were studied. The results showed that the break tenacity was linear with stretching ratio, the elongation at break had a logarithmically hyperbolic function of stretching ratio, and the boiling water shrinkage was parabolic with stretching ratio.
