Beyond low temperature cotton bleaching

We’ve been working with textile auxiliary houses (TAHs) across the globe for many years. Our WeylCat® Pegasus catalyst works by activating hydrogen peroxide during the processing of raw cotton yarns and fabrics – resulting in lower temperature exhaust bleaching systems, reduced energy and water usage, as well as increased asset utilisation and higher cotton yield.

Our community of global and regional users spans Europe, Asia and Latin America. They operate facilities and provide services in some of the most ecologically sensitive parts of the world. From an environmental perspective the case for oxidation catalysis is clear.

As well as achieving high bleaching performance at more moderate temperatures, our technology can be used to shorten the process cycle for fabric treatment and, in some cases, to treat wastewater streams.

The in-use cost savings and important ‘soft’ benefits of catalytic bleaching in textiles have been widely reported, with customers observing:

  • A 15% saving of unit cost per tonne of product bleached
  • Better quality product due to lower pilling and higher crease resistance resulting in an improved ‘handle’
  • Improved cotton yield (by up to 2%)

As our textiles customers can testify, WeylCat® Pegasus Approved systems have had a great deal of success in this sector but there’s still more we can achieve. We are continuing to explore how to translate the benefits of our technologies to continuous and cold-pad-batch set-ups and to further our work in the development of water treatments specific to the textiles sector.
