摘　　要：通过改进的织物折痕回复角测试方法,对不同规格的预定型碳纤维织物的折皱回复性能进行了实验观察.结果表明,随着定型剂浓度的提高,预定型织物的折痕回复角度逐渐减小,织物的保型性越来越好.文中在纺织材料粘弹性理论的基础上,通过力学模型,建立了预定型织物回复角的应力松弛方程,对其折皱回复行为进行了分析,经过和实测值的比较,证明了预定型织物回复角度的变化与普通机织物的变化是相似的,同样符合蠕变规律.The improved fabric crease recovery angle＇s method is carried on the experiment to observe the different specification＇s preform carbon fiber fabric＇s bulging reply performance. The results indicate that,with the concentration of tackifier increasing, the tackified fabrics＇s crease recovery angle reduces gradually, and the fabric keeps the form better. Based on the textile viscoelasticity theory, through the mechanical model,the stress relaxation equation of tackified fabrics recovery angle is established, and the tackified fabric＇s bulging recovery behavior is analysed. By comparing with the actual value, it has proved that the change of tackified fabric＇s recovery angle is similar to the ordinary woven fabric＇s change, similarly conform to the recovery regular pattern.
