• - Lately, textile manufacturers have
  adopted Optical Brightening Agents (OBA) as
  fabric brighteners.

• What Is an Optical Brightening Agent?
• An Optical Brightening Agent is a chemical added
  to a variety of textiles used to make different
  types of garments.
• It is used in the bleaching process to provide
  the highest possible whiteness for the clothes.
• However, the textiles have some color impurities,
  which diminish their whiteness.
• This gives a yellowish hue to the clothes.
• Textile manufacturers use optical brightening
  agents to get rid of this yellow hue by
  effectively utilizing the reflection caused by
  blue light rays.
• The OBAs convert the ultraviolet rays emitted by
  the sun into a visible blue light that makes the
  fabric whiter.
• OBAs are very commonly added to commercial fabric
  detergents to enhance the brightness of clothes.
  Several factors influence the brightness imparted
  by OBA.

• Factors influencing the Optical Brighteners
  performance
• 1. Substrate The material of the fabric also
  affects the output of the OBAs. A white cotton
  fabric will give a more substantial reflectance
  than a weaker fabric like wool.
• 2. Method of application There are different OBA
  application methods that offer different
  whitening effects. For instance, the exhaust
  process of application is known to provide better
  brightness than the padding method of
  application.
• 3. pH The pH value of the solution dramatically
  impacts the solubility and affinity of the OBA
  with the fabric.
• 4. Time Different factors, such as migration
  time and exhaustion rate, influence the OBA
  application.

• Problems Caused By OBAs In Textile Printers
• Every manufacturers widespread use of OBAs
  across the textile industry has raised issues
  with textile printers.
• Different companies sell OBAs, and other brands
  of OBAs correspond to different whiteness levels.
• This creates a problem for digital textile
  printers.
• The digital printers will not be able to impart
  the required color to the fabric as the OBAs will
  interfere with the brightness.
• This results in a mismatch between the processed
  colors and the final products color.
• Moreover, the brightness of the color of the
  final product may vary with the light.
• The need of the hour is to develop standards for
  manufacturing Optical Brightening Agents (OBA) to
  get consistent performance.
• The textile industry is dealing with the lack of
  a regulatory process for the manufacturing of
  optical brightening agents.
• The use of digital printers is increasing, and
  solving this issue can help digital printing in
  the textile industry in multiple ways.

• Conclusion
• OBAs significantly influence the final output of
  the digital printing market.
• Therefore, standardization related to the
  concentration and manufacturing process of the
  Optical Brightening Agent will have a huge impact
  on the textile industry.

  guarantee the quality and supply to ensure the
  best quality output of digitally printed
  textiles.
