Advanced Methods and Tools for Color Measuring and Matching: For Quality Check of Colored Products of Textiles and Apparel Industry

Abstract

This introductory chapter for advances in colorimetry mainly deals with basic principles of color quantification and measurement of different known color parameters, color differences, dye uniformity, setting up of tolerances for different parameters of color differences for assessing color matching efficacy. Few advance analysis of color related issues for textile and apparel industry have made this task easier with the aid of computer aided color measuring and matching system as indispensable tools. Besides that, identification of colorant molecules on colored products by using UV-VIS spectrophotometry become essential now a days. Analysis of quan-tifiable grade/rating of compatibility in between two dyes for a pair of binary mixture of colorants (dyes and pigments), to get a desirable shade also become daily need in the production of dyed textiles and apparel products. Hence, in the present chapter, all such issues of advanced colorimetric analysis for color measuring and matching and quality check of dyed/colored products of textiles and apparel industry, have been discussed here along with principles of working and design features of reflectance spectrophotometer. Few case studies with experimental data as examples are also elaborated here, to understand these issues for better dissemination of knowledge in this field for industry colorist and researchers.
