Colourinn Auxiliaries


We all hate those pale and yellow looking fabrics because of their dullness. The fabric not only looks old but dirty as well and that upsets us. Optical brighteners are used to make the fabrics look brighter and cleaner.

Earlier a blue dye was used to remove the paleness or yellowness of the fabric. The blue dye used to replace the yellowness making it appear brighter. The job of optical brighteners is also quite similar. The optical brightening agent works by transforming UV light waves. The agent improves blue light and reduces yellow light which makes the fabric look brighter. So, it’s the appearance that changes and no yellowness is removed. The best thing about optical brighteners is that these agents stay on the fabric unaffected by heat and chemicals. They can even resist bleaching and that’s why these are used popularly.
