LED Utilization in Cotton Color Measurement

ABSTRACT

The color measurement of the cotton fiber is very important property of the cotton fiber and it plays important role in grading of cotton. Globally used color parameters of cotton fiber are Rd and +b. These parameters are measured by HVI (High Volume Instrument). Cotton color standards are ceramic tiles and cotton samples which are provided by USDA. This paper discusses the utilization of non-contact method by using LEDs as light source to measure the color parameters of cotton standards and comparing with color parameters of HVI. The comparison of cotton color parameters are performed by using the spectral data of different light sources.

摘要

棉纤维的颜色度量是其重要性质，也是棉花分级的重要指标。全球普遍使用的棉纤维颜色参数为 Rd 和+b，这些参数通过 HVI（高容量仪器）测量。由USDA 提供的陶瓷砖和棉花样品充当棉花颜色标准。本文讨论了以非接触方法用 LED 作为光源测量棉花标准品的颜色参数，并与HVI 的颜色参数进行比较。棉花颜色参数的比较是通过用不同光源的光谱数据来进行的。
