摘　　要：对XLA纤维的弹性回复率进行试验。结果表明,XLA弹性纤维在拉伸低于130%时能完全回复,大于200%时急、缓弹回复率急剧下降。拉伸时间在3min内对于XLA纤维弹性回复率影响不大。为此,XLA纤维在成纱和织造中,其拉伸倍数应低于200%。The stretch elastic recovery of XLA fiber was tested and experimental results indicate that when the extension rate is less than 130 percent,XLA fiber has a full recovery. When the extension rate exceeds 200 percent, its stretch elastic recovery has a sharp decline, Stretch time, within three minutes, affects elastic recovery not very seriously. Therefore, in spinning and weaving, XLA fiber＇s extension rate should be less than 200 percent, and the factory should pay attention in production.
