Optical brighteners, commonly known as white dye, is an organic compound that is colorless and can excite fluorescence under ultraviolet light. It can improve the whiteness and gloss of the substance. It is a complex organic compound. Its characteristic is to excite incident light to produce fluorescence, so that the dyed substance obtains a sparkling effect similar to fluorite, making the substance visible to the naked eye very white.
Many industries already have used optical brighteners, such as detergent, paper, plastic, leather etc. So, what are the classifications of optical brighteners? Today, Shanxi Colorshine will update it with you.
What types of fluorescent brightening agent are there!
Fluorescent brighteners are mainly divided into textile special fluorescent brighteners, ink fluorescent brighteners, paint fluorescent brighteners, washing-detergent fluorescent brighteners, paper fluorescent brighteners and so on.
Fluorescent brightening agents can be divided into five categories according to their chemical structure:
- Stilbene type, used in cotton fiber and some synthetic fibers, papermaking, soap making and other industries, with blue fluorescence;
- Coumarin type, with the basic structure of coumarone, used in celluloid, PVC, etc., with strong blue fluorescence;
- Pyrazoline type, used for wool, polyamide, acrylic and other fibers, with green fluorescent color;
- Benzooxynitride type, used for acrylic and other fibers and polyvinyl chloride, polystyrene and other plastics, with red fluorescence;
- Phthalimide type, used for polyester, acrylic, nylon and other fibers, with blue fluorescence.
Classified by model:
For the commonly used models in the optical brightening agent industry, industry professionals often inquire through the commonly used models when purchasing. The current common models can be divided into:
Optical brightener CBS, optical brightener DMS optical brightener AMS, optical brightener ER, optical brightener ER199, optical brightener CXT, optical brightener SBU, optical brightener Agent BBU,, optical brightener VBL, optical brightener BYB, whitening gent APL fluorescent brightener OB, fluorescent brightener OB-1, OPTICAL brightener SWN, fluorescent brightener 4BK, etc.
The above are several common classification methods for optical brighteners. As the earliest domestic manufacturer engaged in the research and production of fluorescent brighteners, Shanxi Colorshine Chemical industry co.,ltd has a complete range of fluorescent whitening agent, covering commonly used fluorescent brightener models (such as CBS, AMS-GX, DMA-X, etc.), and provide One-stop service
