We are also one of the leading names in the field of Optical brighteners which are also known as optical brightening agents. These have in them capacity to absorb light in violet/ultraviolet region of the electromagnetic spectrum and subsequently re-emit light in the blue region.
With the coloring matter, be it natural/present as a contaminant in fiber being generally decolorized by different bleaching methods, the appearance of textile substrate is creams after bleaching. Thus it is necessary that chemical treatment is done to neutralize yellow tint of textile fibers.
The usage areas of Optical brightening agents (OBA) includes:
These are effective only when incident light has significance proportion (like daylight) of UV rays
When material treated with OBAs is exposed to UV black light source, it glows in dark
Anionic OBA’s exhaust on cotton, wool, and silk
Cationic OBA’s exhaust on acrylic and certain polyesters
Non-ionic OBA’s exhaust on all synthetics
Application of Optical Brighteners: Optical brighteners are widely used in:
