摘　　要：对比分析了PTT长丝、PTT/氨纶、PA/氨纶、棉/氨纶包芯纱4种纱线的拉伸及回弹性能,通过定伸长反复拉伸实验,比较了各自弹性回复率随拉伸次数的变化关系。经测试可以得出:PTT长丝及其包芯纱具有优良的回弹性,因此其具备了在非高弹性领域中取代尼龙、氨纶和降低成本的要求。The stretch and recovery properties of PTT fiber and its core-spun yarn were tested in the thesis. The relationship between their elastic recovery ratio and times by the resilient-elasticity recovery at constant elongation testing was analyzed.

关 键 词：PTT 包芯纱 弹性回复率
