What are Optical Brightening Agents?
OBAs, also known as fluorescent brightening agents, are chemical compounds that absorb light in an invisible ultraviolet frequency and re-emit in the form of visible blue light. Blue light opposes, or cancels out, the yellow tint on fabrics, leaving them looking whiter and brighter.

How do OBAs work?
- Absorption: Optical brightening agents are colorless Dyes that absorb UV radiation from the sun or from most artificial lights.
- Emission: This absorbed energy is used for emitting light in the visible region, mostly as blue light.
- Color Compensation: So, the emitted blue light actually complements the yellowish hue of whitish fabric and enables a color compensation for human perception.
Benefits of using OBAs in the Textile Industry:
- Enhanced Whiteness: OBAs efficiently conceal the yellow strain that may have lodged into the fabric making it look dazzling white.
- Improved Color Brilliance: Color appears more saturated and brilliant as OBAs act complementarity in enhancing not just the overall brightness but also the tones.
- Cost-Effectiveness: On an overall note, OBAs are fairly inexpensive in comparison to the alternative techniques to get an equivalent white.
- Versatility: OBAs can be put on cotton, polyester, nylon, or any fiber blends.

choosing an appropriate type of OBA depends on a number of factors such as:
- Type of fabric: Different fibers require different types of OBAs.
- Desired level of whiteness: Brightening power of OBAs may be adjusted in relation to the required target.
- Washing fastness: The OBA must not lose its whiteness after many washings-have superior washability.
