Description
Technical Field
The invention belongs to the field of chemical detection, and particularly relates to a method for rapidly identifying natural dye and synthetic dye.
Background
The natural pigment is a substance extracted from the root, stem, leaf, flower, fruit, seed, etc. of a plant or from an animal and used for dyeing, and is classified into 7 types of pigments, such as red, yellow, blue, green, purple, black and brown, according to the color system. Natural pigments are used in a wide variety of fields, especially in the food field. At present, most of dyes commonly used for dyeing in the textile printing and dyeing field are synthetic dyes. In fact, natural pigments have a long history of application as dyes in textile printing and dyeing fields, wherein the history of application of natural dyes in China has been thousands of years, and natural dyes have been the mainstream of ancient dyeing processes in China. In the 19 th century, with the development of textile industry, natural dyes cannot meet the rapidly growing dye demand, and compared with natural dyes, synthetic dyes have the advantages of colorful color, complete color spectrum, low cost, high color fastness, simple dyeing process and the like, and the increasingly-increased variety of synthetic dyes and the mature process of the process lead the dyeing industry and the textile industry to be improved dramatically, and the synthetic dyes gradually replace the main angle position of the natural dyes in the textile dyeing field.
With the improvement of social development and the living standard of people, people pursue natural and healthy living concepts, the meaning of textiles is expanded from body-shielding cold prevention to functions of attractive appearance, fashion, health, environmental protection and the like, the pollution problem of synthetic dyes to the environment is increasingly prominent, the potential injury to human bodies is also considered important, natural dyes are nontoxic and harmless, natural and elegant, antibacterial and maintenance and other excellent qualities are achieved, and the textile has the advantages of being attractive and popular in the textile printing and dyeing field, and is widely applied to the preparation of various textiles with high added value.
However, based on the high value of natural dyes in high-end markets, a large number of fake textiles which are called to be dyed by the natural dyes are emerging in the markets, so that not only are the rights and interests of consumers influenced, but also the interests of genuine manufacturers are greatly influenced, the normal market order is disturbed, and meanwhile, the popularization of the natural dye textiles is hindered, so that the identification of the textile dyes as the natural dyes or the synthetic dyes has important significance.
At present, the method for identifying the textile dye as the natural dye can be divided into a chemical reagent identification method and an instrument identification method according to the identification means, wherein the chemical reagent identification method achieves the purpose of preliminary identification according to the difference of color development reaction between the natural dye with different structures and properties and chemical reagents such as acid and alkali; the instrument identification method is to identify the dyes according to the difference of different natural dyes in the characteristic spectrogram, and mainly comprises a high performance liquid chromatography, a thin layer chromatography, a laser Raman spectroscopy, a micro optical fiber spectroscopy and the like. The latter, although more accurate, is costly and time consuming and not suitable for rapid detection in the field.
