摘　　要：采用正交试验的方法对氨纶丝进行碱液(NaOH)处理,并对处理后的氨纶丝进行弹性力学性能测试,包括重复拉伸性能、应力松弛性能以及断裂指标,以分析碱处理对氨纶丝力学性能的影响。得出结论:碱处理方式是影响氨纶丝弹性力学性能的主要因素,工艺参数为:碱浓度20 g/L,温度100℃,浸渍时间60 min时,氨纶丝的各项性能达到最佳。Polyurethane filament was treated by alkali solution under orthogonal experiment and the elastic properties including repeated stretch property, stress relaxation and breakage indexes are tested to analyze the influence of alkali treatment on the elastic properties of polyurethane filament. The obtained conclusion is that alkali treating mode is the key factor, and when being soaked in 20g/L alkali solution under 100℃ for 60rains, polyurethane filament obtains optimum level of its elastic property.
