H/P Printing Series

COTFIX H/P Printing Series is a twelve-shade monochlorotriazine reactive-dye range for prolonged printing and steaming. Nuchem positions its high alkali stability and lower reactive character for these process conditions, rather than the lower-temperature dyeing focus of ME. Solubility, rubbing, light, washing and dischargeability values are listed for individual shades. Compatibility or mixing instructions must be checked for the particular grades and printing process, not assumed from the range name.

Approval and conformance coverage varies by product and strength variant. Check product-specific evidence and request documents for your exact COTFIX grade; a series name is not a whole-range approval.

Which shades and fastness values does the H/P Printing Series publish?

COTFIX H/P Printing Series is a twelve-shade monochlorotriazine reactive-dye range built for prolonged printing and steaming. The published table reports solubility, rubbing, light, washing and dischargeability values shade by shade, so every grade stands as a separate row. Solubility runs from 80 to 150 g/L at 30°C across the twelve entries. Dischargeability is not uniform: two yellow shades are fully dischargeable, Orange P2R is partially dischargeable, and the remaining nine shades are not dischargeable. Nuchem checked 34 published ZDHC Gateway products on 28 September 2026, according to Control Union Level 3 records. A buyer should match the exact grade before treating a range-wide figure as applicable to a single printing shade.

D — Dischargeable · PD — Partially dischargeable · ND — Not dischargeable. Understand the table terms.

What makes the H/P Printing Series suited to printing and steaming?

The published H/P list runs across twelve shades, including Turquoise Blue, Navy Blue and two blacks, with solubility from 80 to 150 g/L at 30°C. Nuchem describes H/P Printing Series as mixable with VS Series dyes for vibrant dark prints. Confirm grade compatibility for the real printing conditions rather than assuming every combination is suitable. Share the fibre, shade and printing or steaming process so the correct grade can be assessed against a production trial.

How is lot-to-lot consistency held for the H/P Printing Series?

Fastness figures are worth only as much as the reproducibility behind the published numbers. For the H/P Printing Series, Nuchem describes a three-point quality check, laboratory support and production-lot records, so a selected grade can be followed from one batch to the next. The check runs before delivery, and the records support a repeat order for a printing or steaming shade. Buyers can ask for the test record that matches a chosen grade.

How does Nuchem treat wastewater from dye manufacturing?

Wastewater treatment at the Sayakha plant in Bharuch is published as a 100% zero liquid discharge operation, so no liquid process effluent leaves the site. The described train pairs reverse osmosis with Mechanical Vapour Recompression (MVR) and an Agitated Thin Film Dryer (ATFD), rated at 53 kilolitres per day (KLD). Condensate captured by the train is recycled into dye manufacturing, and the dried sludge is disposed of at Gujarat Pollution Control Board (GPCB) approved Treatment, Storage and Disposal Facility (TSDF) sites.

Manufacturing also runs at Vatva (Ahmedabad), but the zero liquid discharge status and the 53 KLD capacity are documented for Sayakha and should not be read across without confirmation. For H/P Printing Series buyers preparing a supply-chain review, a chemical-product approval does not certify a factory's water-treatment performance.
