Abstract:

Fibers are the basic unit of textile, and fiber dyes are the colored substances that have affinity for fibers and are able to absorb and reflect certain visible wavelengths of light. The analysis of fiber dyes is extremely important in many fields, such as textile industry, environmental protection, forensic science and antiquarian research. However, it is challenging to analyze the fiber dyes because of the extremely small sample sizes, the desire for nondestructive techniques, and the vast complexity of modern dye compositions. Nevertheless, significant amount of researches have been done to build new methods and techniques for efficient, sensitive and nondestructive fiber dye analysis. Those methods can be divided into three categories:spectroscopy, chromatography and mass spectrometry. The combination of chromatography and mass spectrometry, especially the development of soft ionization mass spectrometry, makes the detection of trace dyes in a complex fiber matrices become easier to implement. In this paper, the classification and characteristics of fiber dyes are summarized briefly, and the analytical methods and the latest progress for the determination of fiber dyes in recent years are reviewed. The challenge of fiber dye analysis is also discussed, hoping to provide some references to develop new methods and techniques.
