Status quo and development of the fluorescent whiteners for textile fibers

The fluorescent whiteners make the white text. fibers whiter and the colored ones more brilliant, and are one of the means of raising the added values of the textiles and garments. Their industrial production was initiated in the 1940's, and after more than 60 years, there are now several hundreds of kinds of products, from the original aq. solns. to the actual high-rank non-sol. ones suitable for natural fibers. A systematical classification was done according to their chem. structures to find out that the product no. and quality of the Chinese fluorescent whiteners are still inferior to the world level.
