【摘要】 为研究天然彩色棉/白棉混纺纱线的色泽与彩棉含量的关系,应用计算机测色配色系统Datacolour对5种不同彩棉含量的彩棉/白棉混纺纱线的色泽进行测试。结果表明随着彩棉含量的变化,色调的变化不很明显,明度随彩棉含量的增加而减小,饱和度随彩棉含量的增加而增大。根据5种试样的K/S值测试结果,运用Origin 6.1软件,经过曲线拟合得出混纺纱线的彩棉含量与K/S值的关系为一元线性关系。然后进一步运用回归分析,得出不同彩棉含量的彩棉/白棉混纺纱线的K/S值的预测范围。更多还原

【Abstract】 To research the relation between the color of colored cotton/cotton blended yarn and colored cotton′s proportion,the color of 5 kinds of blended yarns with different colored cotton′s proportion were tested using computer color-measure and color-matching system,the results show that along with the change of colored cotton′s proportion the variety of hue of blended yarns is not very obvious,lightness is decreasing and chroma is increscent.Based on the value ofK/Sof 5 samples,by curve fitting using software Origin 6.1,it is drawn that the relation between colored cotton′s proportion and the value ofK/Sis linear relationship.Then,using regression analysis,the predicted range of blended yarns with any colored cotton′s proportion is drawn.更多还原
