摘要
探讨形状记忆整理织物在热环境下的折皱回复角随温度变化的规律。结果表明,形状记忆整理织物在热水和热空气介质中,在激发温度60℃附近具有温度响应,折皱回复角显著增大。说明形状记忆整理织物对定型时的平整形状具有记忆,并在激发温度附近回复形状。由于导热系数不同,相同温度下,热空气中的折皱回复时间比热水中的回复时间长得多。采用非线性回归方法进行计算发现,形状记忆整理织物在热环境下的折皱回复角与温度存在指数关系。热水介质中温度与折皱回复角函数为y=3.446 7x0.557 9;热空气介质中温度与折皱回复角函数为y=3.282 0x0.591 0。
Under the hot environment the changing of wrinkle recovery angle（WRA） of fabrics finished by shape memory polymer with temperature is discussed.The result shows that under both hot water and air environment the fabrics can respond to temperature with a significant increase of the WRA at stimuli temperature about 60℃.It indicated that at about switch temperature the shape memory fabrics remember its set shape and recover to flat shape.Under the same temperature the wrinkle recovery time in hot air is much longer than in hot water due to the different coefficients of heat transmission.Nonlinear regression analysis method was used for finding the relationship between the wrinkle recovery angle and the temperature of shape memory fabrics in hot environment.The result shows that there is logarithm relationship between them.The function of the wrinkle recovery angle with temperature in hot water is y=3.446 7x^0.557 9,and the function in hot air is y=3.282 0x^0.591 0.
