Fluorescent brightener is a kind of color conditioning agent, which has the effect of brightening and brightening. It is widely used in many fields such as papermaking, textile, detergent, and so on. There are about 15 basic structure types of fluorescent whitening agents and nearly 400 structures. There are two types of fluorescent whitening agents that China allows to add to laundry detergents: stilbene biphenyls (such as CBS, etc.) and bistriazine amino stilbenes.
The principle of the fluorescent whitening agent is to absorb the invisible ultraviolet light in the light and emit visible blue light. After being superimposed with the yellow light emitted by the fabric, it complements the formation of white light, which increases the white light emitted by the fabric, and the naked eye can feel the white fabric. Becomes bright white, this is the bright white effect. Fluorescent brighteners can absorb invisible ultraviolet light (the wavelength range is about 60-380 nm), and convert it into longer-wavelength blue or violet visible light, thereby compensating for the undesirable yellowish color in the matrix, and reflecting more The original incident wavelength is more visible light in the range of 400-600 nm, which makes the product appear whiter, brighter and more vivid.
Application: Fluorescent brightener is suitable for non-transparent films and all rigid PVC products
