摘　　要：采用微波对羊毛织物进行辐射处理,通过扫描电镜和X射线衍射等技术研究了处理前后羊毛纤维表面形态结构和结晶度的变化。微波辐射处理后采用兰纳素活性染料和派拉丁1∶1金属络合染料对羊毛织物进行染色,在研究了处理前后纤维的染色吸附和扩散性能后,发现处理后纤维上染速率和染色扩散系数提高。微波处理破坏了羊毛纤维表面的鳞片结构,使羊毛的初始染色壁障被打破,染料容易从染浴向纤维内扩散。Wool fabric was treated with microwave irradiation.The surface morphological structures and crystallinity of the untreated and microwave-treated wool were investigated with scanning electron microscopy（SEM） and X-ray diffraction（XRD）.Wool was treated with microwave and then dyed with Lanasol reactive dyes and Palatin 1∶ 1 metal complex dyes.Adsorption behavior and diffusion coefficient were also studied.A higher dye uptake rate and increased diffusion coefficient of treated fibers were observed in the dyeing test,which was attributed to the damages of wool surface morphological structure under microwave irradiation.
