A Statistical Analysis of the Intra-Sample Distribution and Variation of Cotton Color and Its Application

Cotton color’s intra-sample distribution and variation may indicate the variation of fiber quality that influences the quality of textile product.  Currently the colorimeter method for measuring cotton color provides a cotton’s overall color grade; its result does not include information about the intra-sample color distribution and variation.  We conducted an investigation using color image analysis and statistical analysis to study the intra-sample distribution and variation of cotton color.  We present theoretical and experimental work of the study, and the statistical aspects of the intra-sample distribution and variation of cotton color and the applications.
