Optical brightener is a fluorescent dye, or white dye, and it is also a complex organic compound. Optical brightener characteristic is that it can absorb UV light and radiate the visible blue light, so that the dyed substance can obtain a sparkling effect similar to fluorite, making the substance visible to the naked eye very white.
Optical brightener is a kind of color conditioning agent, which has the effect of whiting and brightening. Optical brightener is widely used in many fields such as plastics ,paper making, textile, detergent and so on.
Many industries are now beginning to use optical brighteners, such as paper, plastic, leather, and detergent. At the same time, fluorescent whitening agents are also used in many high-tech fields, such as: fluorescence detection, dye lasers, anti-counterfeiting printing, etc., and even high-sensitivity film for high-altitude photography. In order to improve the sensitivity of the photosensitive latex, fluorescence will also be used Brightener.
Fluorescent brighteners are mainly used to remove yellowing and whitening of recycled plastics. Below we mainly introduce the characteristics and uses of the two best-selling fluorescent brighteners in the Indonesian market.
Oba(optical brightening agent) for cotton are mostly powdery, generally light yellow in appearance, anionic, easily soluble in water, and the solution is slightly yellow, fluorescent, and neutral. It can be absorbed by the fiber in the aqueous solution, has excellent leveling and permeability, can directly dye the fiber, and is convenient to use.
Among all the optical brighteners for plastics, optical brightener OB-1 for plastics is the most popular in the market.
Brighteners are widely used in the production of textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints. Brighteners, also called optical brighteners and fluorescent brighteners, are organic compounds that can improve the whiteness of fiber fabrics and paper.
