摘　　要：为了模拟绿色植被的光谱特征,以亚甲基双萘磺酸钠(NNO)为分散剂,采用喷雾干燥技术制备了自分散纳米颜料绿,通过熔融共混法制备了生物基尼龙56(PA56)原液着色纤维,探究纤维的微观结构、以及热、力学、可见光-近红外光谱性能.结果表明当颜料蓝-6124和颜料黄-1103复配质量比为2:1时,研制的自分散颜料绿能够较好地模拟绿色植被在可见光-近红外(400~1200 nm)的光谱特性;自分散颜料绿在PA56纤维内分散均匀,相容性好,且纤维的热性能基本保持不变,力学性能稳定;原液着色PA56纤维的光谱距离小于0.65、光谱角度小于0.13 rad,光谱相关系数高于0.98,达到了GJB 1411-2015二级光学伪装和二级光谱伪装的要求;颜色可以很好地模拟GBJ 1082A-2021中伪装网颜色MG1151与DG0730(色差<3);耐晒牢度>6级,耐水洗牢度和耐汗渍牢度均为4~5级.In order to simulate the spectral characteristics of green vegetations,self dispersed nano-sized pigment green was prepared by a spray drying with sodium salt of polynaphthalene sulphonic acid(NNO)as the dispersant,which was used to prepare PA56 dope dyeing fibers by the melt blending.Moreover,the microcosmic structure,thermal,mechanical,visible-near infrared spectral properties of the fibers were investigated.When the mass ratio of pigment blue-6124 to pigment yellow-1103 was 2:1,the self-dispersed nano-sized pigment green could well simulate the spectral characteristics of green vegetation in visible near infrared(400-1200 nm)region.The selfdispersed nano-sized pigment green is uniformly dispersed in PA56 fibers,with a good compatibility.In addition,the thermal properties of the fibers remain basically unchanged,and the mechanical properties are stable.The spectral distance of the PA56 dope dyeing fibers is less than 0.65,the spectral angle is less than 0.13 rad,and the spectral correlation coefficient is higher than 0.98,which meets the requirements of GJB 1411-2015 for secondary optical camouflage and secondary spectral camouflage.The color of PA56 dope dyeing fibers can simulate the camouflage net colors MG1151 and DG0730 in GBJ 1082A-2021 very well(color difference<3).The sun fastness of PA56 dope dyeing fibers is greater than level 6,and the wash fastness and sweat fastness are both level 4-5.
