Also known as optical brightener, fluorescent whitening agent. Fabrics, etc. are often yellow due to colored impurities. In the past, chemical bleaching was used for decolorization. Now, the method of adding brighteners to products is used. Its function is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which is complementary to the original yellow light radiation and becomes white light, improving the whiteness of the product under sunlight. Brighteners have been widely used in textiles, paper, washing powder, soap, rubber, plastics, pigments and paints. In the past, in the textile industry, single-component whitening agents were mostly used. The defect of this kind of whiteni...
