摘　　要：弹性纱常用于运动紧身衣、压缩绷带,以及改善普通紧身服装的功能性,有利于人体运动和能量的迅速恢复。这些服装绝大部分用于短期的体育活动,适用于人们需要无限能量和力量的状况。评估动态弹性回复性能和回复率,以研究纱线和织物对提高运动员耐力水平的贡献是非常必要的。研究了聚酯纱捻度对聚酯/氨纶空气包覆纱弹性的影响。结果显示:每米纱线的节点数、动态弹性回复率(DER)和回复率(RR)随聚酯包覆纱捻度的增加而增大,并且影响显著。Elastomeric yarns are used for tight fit sportswear compression bandages and now functional in the regular tight fit manufactured garments for easy body movement and quick energy recovery.These garments are mostly used for short duration sports activities,wherever the person requires unrestricted energy and power.Assessment of dynamic elastic recovery and recovery ratio is necessary to study the contribution of yarns and fabrics for sportsmen performance to improve their starmina level.The effect of twist levels in polyester yarn on elasticproperties of polyester/spandex air covered yarn is studied.It is concluded that the number of nodes/m,dynamic elastic recovery（DER）and recovery ratio（RR）of produced yarn increases with the twist levels in polyester sheath yarn and has significant effect.
