Optical brightener
The role of the brightener is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which complements the original yellow radiation to become white light, and improves the whiteness of the product under sunlight. Brighteners have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints.
Generally, brighteners are divided into two categories, one is water-soluble brighteners, and the other is water-insoluble brighteners. The former can be used as a brightener for paper, paint, washing powder and cotton fabrics. The latter can be used for whitening of chemical fibers and plastics.
It is often divided into:
Fluorescent brightener for detergents; Fluorescent brighteners for textiles; Fluorescent brighteners for papermaking; Fluorescent brighteners for plastics and synthetic materials; Fluorescent brighteners for other purposes.
This product is especially used for the molding and processing of various plastics and plastic products under high temperature. Because of its good heat resistance, light resistance and chlorine resistance, it is a brightener for polyester fibers. Polyester, cotton and other fiber blended fabrics The whitening effect is also particularly ideal, and can be used for the whitening of polyester stock solution.
