What's Optical Brighteners

Optical brighteners are special chemicals that improve the whiteness and brightness of textiles. By absorbing ultraviolet light and converting it into blue-violet visible light, brighteners can effectively offset the yellow or dark tones that may exist on textiles, making the fabric appear brighter and more vivid white.
 
They are commonly used to treat various fibers such as polyester, cotton, acrylic, nylon, etc., and are widely used in textile printing and dyeing and finishing processes. Textile brighteners can not only enhance the visual effect of products, but also enhance their market competitiveness. They are important additives for improving quality and appearance in the textile industry..
