面料回弹性看'回复率'——拉伸后能快速复原不松垮的属于优质弹力面料；廉价面料多次拉伸后膝盖处会鼓包变形，判断方法是看面料克重与氨纶配比，克重200-280g/m²且含氨纶的双面弹面料回弹表现较好

Unverified判断弹力回复性：拉伸下摆或袖口后松手，能立即回弹无褶皱松弛痕迹的为优；氨纶含量相同下，锦纶（尼龙）混纺比涤纶混纺回弹更持久、洗后不易松垮82% similarUnverified看罗口（下摆和袖口）弹性：优质卫衣罗口含氨纶，拉伸后能快速回弹，劣质罗口洗几次后松垮变形，选购可实测回弹性82% similarUnverified购买时用手压后观察回弹速度可初判蓬松度：优质高蓬松羽绒按压后能快速回弹恢复原状，回弹慢或压不起来说明填充物含绒量低或以毛片为主82% similarUnverified领口回弹性优先于弹力大小：反复拉伸后能恢复原状（含氨纶/弹性纱2%-5%）的领口，洗几次后不松垮；纯棉罗纹领虽软但易越洗越大导致漏风81% similarUnverified面料回弹性差（洗几次后松垮）的判断：手拉伸后松开是否立刻回位；含锦纶（尼龙）的比纯涤纶回弹更持久，纯棉+氨纶款塑形力会随穿着次数快速衰减80% similar
