摘　　要：为研究现有白色无机纳米颜料对织物雪地伪装性能的影响，制备雪地伪装效果相对更好的伪装织物，实验采用涂料印花工艺制备不同种类印制织物，通过测试印制织物反射率，讨论了纳米SiO2和纳米MgO粒子作为印花颜料在单独或复合使用时对印制织物雪地伪装性能的影响，并表征了印制织物的表面形貌，测试了印制织物的白度和耐洗性能。结果表明：当纳米SiO2和纳米MgO颜料单独使用时，印制织物在紫外一定波段（250～280nm和280～320nm）的反射率值偏低，而将纳米SiO2和纳米MgO颜料按质量比2：1复合，且复合颜料用量为12％时，印制织物的反射率高达80％以上，雪地伪装性能优于颜料单独使用时的印制织物，弥补了两种颜料单独使用时的缺陷，且白度与耐洗性能良好。In this study, different kinds of printed polyester fabrics with better camouflage effects were prepared to study influence of white inorganic nano pigment on camouflage property of fabrics in snowfield. Pigment printing technology was adopted to prepare diverse printed fabrics. Influence of nano-SiO2 and nano-MgO particles as pigment print on camouflage property of fabrics in snowfield during single use or combined use was discussed through testing reflectance of printed fabrics. Also, the surface morphology of these fabrics was characterized. Meanwhile, the whiteness and washing fastness of these fabrics were tested. These results show that reflectance value of printed fabrics is relatively low in the certain UV region （250~280 nm and 280~320 nm）, when nano-SiO2 and nano-MgO pigment are used singly; the reflectance of printed fabrics is as high as 80% when nano-SiO2 and nano-MgO are mixed according to the mass ratio of 2 ： 1 and dosage of composite pigment is 12%. Snowfield camouflage property of the fabrics is superior to the fabrics during single use. This makes up for defects during single use of two pigments, and the whiteness and washing fastness are good.
