摘要：

针对有色纤维颜色测量结果不准确、不稳定的问题,研究了在应用分光光度计测量纤维颜色时,纤维样品制备过程中不同因素对测量结果的影响,并尝试为后期的纤维混色研究提供一种标准的颜色测量方法。选取品红、蓝、黄3种颜色的棉纤维为实验原料,分析了纤维厚度、密度对其颜色测量结果的影响;并对比了纤维纵向、横向和任意排列时,颜色测量结果的差异。结果表明:颜色测量时纤维任意排列,样品厚度大于0.8 cm时,厚度变化对颜色测量结果的影响色差小于0.1;当纤维质量不低于10 g时,密度变化对颜色测量结果的影响色差小于0.2。

关键词: 有色纤维, 棉纤维, 分光光度计法, 颜色测量, 色差

Abstract:

In view of the lack of precision in directly measuring the color of colored fibers, the influence of different factors on the measurement results of the fiber sample preparation process was studied. An attempt was made to provide a standard color measurement method for fiber blending. The cotton fibers magenta, blue and yellow were selected and used as the experimental materials. The color parameters of the fibers changed with the variation of fiber thickness. The density of the fibers was related to the porosity and had an influence on the color measurement results. The fibers were arranged differently (vertical, horizontal, arbitrary) and the color measurement results were compared. The fibers are randomly arranged during the color measurement process, when the sample thickness increased to 0.8 cm or above, the color difference is less than 0.1 for the changes of thickness. The weight of the fibers in the self-made container is 10 g or heavier, the color difference is less than 0.2 for the changes of density.

Key words: colored fiber, cotton fiber, spectrophotometer method, color measurement, color difference
