【摘要】 应用直接染料和阳离子染料分别对棉和苎麻织物进行染色,测定了染色织物的L*a*b*值,并计算了同一染料在相同条件下对两种织物的彩度差值、色差值和K/S差值。结果表明:几种染料对棉和苎麻的染色存在不同程度的差异性,用直接染料和阳离子染料染色的棉织物的K/S值和彩度值明显高于苎麻织物。使用直接耐酸大红4BS、直接枣红GB、直接冻黄G、直接黄棕D3G、阳离子嫩黄O、阳离子艳蓝RL对棉和苎麻的织物进行染色时,棉和苎麻的织物之间的色差值均大于5。更多还原

【Abstract】 Direct dyes and cationic dyes were used to dye cotton and ramie fabrics,respectively.The values of Lab,chroma difference,color difference and K/S were measured to study the color difference between cotton fabrics and ramie fabrics after dyeing.It was found that dyed cotton fabrics had higher K/S and chroma values,compared with the dyed ramie fabrics with both direct dyes and cationic dyes.When Direct Fast Scarlet 4BS,Direct Bordeaux GB,Direct Chrysophene G,Direct Yellow Brown D3G,Basic Flavine O and Cationic Brilliant Blue RL were used to dye the fabrics,all the color difference values between the dyed cotton and ramie fabrics were higher than 5.更多还原
