Salient Features

Chemifix CN Dyes

The CHEMIFIX CN dyes are bi-hetero bifunctional reactive dyes for warm exhaust dyeing. Highly compatible range for Trichromatic shades and high all-round fastness performance. Excellent reproducibility and outstanding washing-off properties resulting in increased productivity.

Highlights of CHEMIFIX CN Dyer Benefits
Outstanding speed of washing off
  • high degree of fixation (over 80%)
  • medium affinity of the dyes
  • very good diffusion
  • bond to cellulose, stable in both alkaline acid condition
Top productivity
  • save water, energy and time
Excellent wet and wash fastness
  • appropriate dye selection fulfills very high requirements (M&S, GAP... for ex.)
  • excellent multiwash fastness (included CI OA)
Robust dyeing system, outstanding reproducibility
  • excellent compatibility of the trichromy dyes
  • on-tone build up
  • high degree of fixation
  • very good leveling properties
Fewer corrections, fewer re-dyeing
  • right first time
  • excellent lab-to-bulk and bulk-to-bulk reproducibility
  • improved appearance of the fabric
High light fastness combinations Excellent light fastness
  • appropriate dye selection fulfills very high requirements (M & S, GAP, IKEA... for ex.)
Very good ecological properties
  • high degree of fixation (over 80%)
  • outstanding washing off, less washing bath needed
  • AOX-free range
Cost saving
  • shorter washing-off process: saves energy, water and time
  • less dye in waste water: reduced ecological costs

Note

  • In order to increase the solubility of the dyes and reduction of substantivity as well as cooling of the pad liquor, the use of 30-50 gpl Urea is recommended.
  • Fixation (Dwelling) time is 10 - 12 hours depending on the depth of the shade.
