Every lot tested.
Every shade traceable.
Repeat orders live or die on shade consistency. Nuchem runs a three-point quality check on every lot of COTFIX® reactive dye before it leaves the plant, across four in-house laboratories, and keeps a database of every production lot — so a shade approved on one order can be matched and traced on the next.
How every lot is checked.
Every dye manufactured undergoes a rigorous three-point quality check system before delivery.
QC labs at the Ahmedabad head office, Ludhiana regional office, and both Sayakha and Vatva factories.
A comprehensive database of all production lots ensures traceability and consistent delivery, lot after lot.
Inside our laboratories
Four QC labs · every lot tested before dispatch
The data these labs produce is published.
Testing is only useful if you can see the result. Solubility, rubbing fastness dry and wet, light fastness, washing fastness and dischargeability are published for all 58 COTFIX® shades across the eight series, rated on standard grey scales — shade by shade, not summarised.
Need a shade matched?
Send us the substrate, the process and the standard you are matching to. Our laboratories will work to it and dispatch a sample.
