摘　　要：为提升热湿处理后免烫羊毛织物的保形性能,分别在不同温度和湿度条件下对免烫羊毛织物进行处理。借助织物折皱弹性测试仪、万能强力仪、扫描电子显微镜、傅里叶红外光谱仪、X射线衍射仪等对处理前后免烫羊毛织物的折皱回复角、断裂强力和微观结构进行测试与表征。结果表明:免烫羊毛织物的折皱回复角随着测试温度和相对湿度的升高而下降,其中经90%相对湿度、100℃条件处理的免烫羊毛织物,折皱回复角降低为原样的88.2%;当免烫羊毛织物的处理温度不变时,断裂强力随着相对湿度的增高而逐渐下降;经过较高温度热湿处理的免烫羊毛织物,其表面纤维受到损伤,结晶度基本没有变化。In order to maintain the shape retenion performance of anti-creasing wool fabrics,it is of great significance to study the influence of thermal and moist conditions on the fabrics shape retention performance.In this research,the orthogonal experiments were carried out to study the changes in temperature and humidity on anti-creasing wool fabrics.Wrinkle recovery angle,the breaking strength and microstructure of a selected anti-creasing wool fabric before and after treatment were characterized using fabric wrinkle elasticity tester,strength tester,scanning electron microscope,Fourier infrared spectroscopy and X-ray diffractometer.The results show that the wrinkle recovery angle of the anti-creasing wool fabric decreases with the increase of temperature and relative humidity.Among them,the wrinkle recovery angle of the anti-creasing wool fabric treated with 90%relative humidity and 100℃conditions is reduced to 88.2%of that of the original fabric.With fixed processing temperature,the breaking strength of the anti-creasing wool fabric gradually decreases with the increase of the relative humidity.In terms of microscopic morphology and structure,there witness damages in fibers on the fabric surface for the anti-creasing wool fabric treated with higher temperature and humidity,with no obvious change in crystallinity of the fabric.
