Evaluation and Testing of Dyes Before Use in Textile Dyeing

Abstract

Progress in methods of test for dyes and dyed textiles is reviewed. This is a broad topic which touches on many aspects of coloration technology and inevitably the treatment of some areas of the subject has to be brief and incomplete. Many recent trends in dye application technology affect both the nature of tests to be applied and the criteria considered when interpreting the results of the tests. This subject is reviewed from the viewpoints of both the dye manufacturer and the dye user, in order to bring out the essential similarities in approach. Typical parameters of dye selection are tabulated and classified according to the nature and purpose of the tests involved.
