摘　　要：从有色涤纶的呈色原理出发,研究其局部与整体呈色特征。类比彩色印刷中Neugebauer方程的建立,分析色纤维配色的适用性及其呈色原理并建立模型,对建立的模型通过试验进行颜色预测准确性验证,并分析色纤维配色的原理及产生误差原因。结果表明:油墨四原色的混合色域空间大于有色涤纶;由色纤维颜色预测值与实测值之间的色差比较发现,Photoshop测色相对于电脑测色仪测色颜色预测效果更好;试验条件、纤维混和比例等均会对颜色预测效果产生影响。有色涤纶和白色莱赛尔纤维混和时,预测模型色差变化趋势基本与涤纶混和色差一致。认为:依托光学模型以及类比Neugebauer方程所建立的色纤维混和颜色预测方程有助于色纺纱配色模型的准确建立。Started from color generation theory of colored polyester,its partial and whole color generation characterization were studied. Analogized from Neugebauer formular establish in color printing,adaption of color generation for colored fibers and its color generation theory were analyzed and model was established. Color prediction accuracy verification was performed on established model by testing. Color matching theory of colored fibers and error causes were analyzed.Test results showed that blended color gamut space of ink four primary colors was larger than that of colored polyester. Found by comparing chromatic aberration of prediction color of colored fibers with practical test values,color prediction effect of Photoshop color test was better compared with that of computer color tester.Color prediction effect was affected by experimental condition,fiber blending ratio and so on.When colored polyester and white lyocell fibers were blended,chromatic aberration change trend predicted with model was basically same as chromatic aberration of polyester blending.It is considered that color prediction formular for colored fibers blending established relying on optical model and analogized Neugebauer formular is beneficial to establish color matching model for colored spun yarn accurately.
