摘　　要：为模拟绿色植被的光谱反射特征和颜色,利用C.I.酸性黄199、C.I.酸性蓝324、C.I.酸性蓝185染料对生物基锦纶56进行染色,研究了染色工艺、染料用量和复配比对染色织物反射光谱曲线(400~1200 nm)的影响,开发了仿绿色植被的浅绿、中绿和深绿染料体系,分析了染色织物的光谱模拟效果。结果表明:在60℃恒温染色保温40 min的条件下,C.I.酸性黄199、C.I.酸性蓝185和C.I.酸性蓝324的配伍性好,上染率接近100%;黄色染料影响“绿峰”,蓝色染料影响“红边”,染料用量增大,红移量变大,有利于“绿峰”和“红边”红移;复配染色织物在400~1200 nm范围内的光谱反射率曲线与标准植被反射曲线之间的光谱距离均小于1.3、光谱角度均小于0.1 rad,光谱相关系数均达到0.987以上,满足GJB 1411A—2015《地地导弹武器装备系统伪装要求》二级光学伪装和二级光谱伪装的要求;其颜色模拟符合GJB 1082A—2021《伪装网用颜色》对伪装网颜色DG0850、MG1048、YG1550色差小于3的要求,且织物各项色牢度良好。Objective Imitating the color and spectral reflection characteristics of green vegetation contributes to the military camouflage.Bio-based polyamide 56 has many merits such as high strength,wear resistance,good chromaticity,lightweight and softness.In this research,a bio-based polyamide 56 fabric was dyed in green color to simulate spectral characteristics of vegetation by using acid dyes.Method In this work,weak acid dye compounds were used to dye the bio-based polyamide 56 fabric to simulate the color and spectral reflection of green vegetation by adjusting the ratio of C.I.Acid Yellow 199,C.I.Acid Blue 324 and C.I.Acid Blue 185.The influence of dyeing,dyes dosage,and blending on spectral reflectance curve from 400 to 1200 nm of dyed fabric were studied.The spectral distance,angle and correlation of the spectral reflectance curves of dyed fabrics were calculated against the standard curves of green vegetation.The fabric color difference and fastness were also measured.Results When adopting the room temperature dyeing-controlled heating method dying process,C.I.Acid yellow 199,C.I.Acid Blue 324 and C.I.Acid Blue 185 demonstrated a high dyeing rate and yield,and poor compatibility.When adopting the homo-thermal constant temperature dyeing method with 60℃temperature,the compatibility of the dyes was improved.It was revealed that the higher was the dye concentration,the greater was the redshift of the spectral reflection curve.C.I.Acid Yellow 199 has a low reflectivity between 380 and 450 nm,which could be used to simulate the absorption of ultraviolet and visible light by green vegetation,and form a"green peak"at 550 nm during mixed dyeing.The"red edge"of C.I.Acid Blue 324 is at 630 nm,which shows bule shift 50 nm from the green vegetation.C.I.Acid Blue 185 has a strong absorption peak near 680 nm,and the weak absorption peaks around 880 nm and 960 nm without overlapping with water peaks of green vegetation.Therefore,C.I.Acid Blue 185 was used to simulate the"red edge"of green vegetation.The mixture of any two d
