摘　　要：利用电子单丝强力仪,按照L16(43)正交表设置拉伸速度、拉伸停置时间和松弛停置时间,测试纤度为33.3dtex、定伸长率为300%的氨纶丝定伸长拉伸弹性。分析氨纶丝弹性回复率和应力松弛率两项指标发现,拉伸速度影响最为显著,拉伸停置时间和松弛停置时间的影响效果因指标不同而有差异;试验时,综合考虑试验效果和效率,可以选择较大的拉伸速度、较长的松弛停置时间和较短的拉伸停置时间。This paper sets stretching speed, stretching time and relaxation time according to L16 （4^3） orthogonal table with electronic monofilament strength tester and tests specified elongation and tensile elasticity of spandex filament with fineness 33.3 dtex and specified elongation 300%. The analysis on elastic recovery rate and stress relaxation rate of spandex filament finds that stretching speed has the most significant influence and impact effect of stretching time and relaxation time is different due to difference in index. During the test, considering test effect and efficiency, high stretching speed, long relaxation time and short stretching time can be selected.
