Today, PA dyers face several challenges. On the one hand, they must meet the stringent requirements of the MRSL lists. At the same time, polyamide dyers must meet the high standards for alkaline perspiration and wash fastness for saturated colors. “Pafix BOND“ from speciality chemicals manufacturer CHT, headquartered in Tübingen, enables sustainable polyamide dyeing while meeting the high performance requirements of brand owners and retailers. Using the levelling agents “Sarabid IPD“, “IPM“ and “IPF“ in the dyeing process can achieve excellent levelness.

Relevant textile standards

“Pafix BOND“ meets a wide range of relevant textile standards – including bluesign®, ZDHC, OEKO-TEX® Standard 100, as well as bisphenol-free, phenol-free, and formaldehyde-free formulations. Despite its bio-based formulation, the system offers the same quality and performance as conventional chemical finishes – especially for medium to dark shades. When combined with select “Bemacid®“ dyes, which have been awarded a Gold-level Cradle to Cradle Material Health Certificate, users receive a complete, sustainable system for the circular economy.

Specific Savings with “Pafix BOND“

Of course, CHT Group always evaluates new developments in terms of their carbon footprint. Compared to conventional products, a reduction in the carbon footprint of approximately 20 % is expected. Considering the CO2 absorption by the bio-based raw materials during their growth, the manufacturer even expects the carbon footprint of PAFIX BOND to be negative.

In addition, CHT’s more sustainable polyamide dyeing technology achieves significant resource savings:

• up to 25% reduction in water consumption,

• up to 20% energy savings,

• up to 17% shorter processing times.
