摘　　要：为建立较理想的关于PTT织物形状记忆效果的测试评价方法及表征指标,选择6类织物结构相近的代表性织物,设计了织物弧度塑形性的主观和客观评价方法,以及力刺激复平性能的客观试验方法。试验结果表明:织物弧度塑形性的主观和客观评价结果之间保持了较好的一致性,从而证明织物弧度塑形性的客观检测方法有实用价值;力刺激使织物复平的客观试验方法同时考虑了温度的影响,较好地模拟了人手摸复平的效果,既客观定量,又方便易行。For developing ideal testing methods and expression of related indexes for shape memory effects of PTT ＂shape memory＂ fabrics, six kinds of representative fabrics with similar textile structure were chosen, and subjective and objective evaluation methods for radian plasticity and objective evaluation methods for force stimulating recovery were designed. The experimental results suggested that there was a good correlation between subjective and objective evaluation methods for radian plasticity, thus proving that objective evaluation methods for radian plasticity is valuable and practical. Objective evaluation methods for force stimulating recovery has taken into consideration the impact of temperature, so that a good simulation of the recovery after being touch by hand is achieved. It is proven that the test method is both objective and convenient.
