Reactive dyes or vat dyes ?
Why do dyers use/prefer reactive dyes instead of vat dyes
- Higher versatility of application processes (pad-batch, exhaust, continuous)
- Bright, fashion, deep shades achievable
- Meets most modern fastness requirements in Apparel and Home Textile
NOVACRON NC Dyes
Textile EffectsResearch & Technology /JMS C.O.C Mumbai, February 2009
- Meets most modern fastness requirements in Apparel and Home Textile
- Cheaper recipe cost particularly for medium/deep shades
- More simple dyeing / application procedures, better penetration
- no reduction step - no oxidizing
- No specks by dyeing pale shades
- Higher productivity due to easier shade planning (reactive/vat product mix not easy to
manage in bulk)
- Easier stripping and shade correction
Use of vat dyes
Especially for dyeing pale and medium shades, and when the brightness is not an issue
For what shades do the dyers prefer using vat dyes?
Apparel and Home textiles
Textile EffectsResearch & Technology /JMS C.O.C Mumbai, February 2009
Reasons .........
The reproducibility of vat dyes is much better but c are must be taken to application conditions (dispersing, steaming, rinsing, oxidizing, soaping)
The fastness requirement are fulfiled
The Solution !!A selection of new reactive dyes having the shade
of vat dyes, combining the reproducibility of vat
dyes and that can be applied as reactive dyes

Shade change with NOVACRON NC
Textile EffectsResearch & Technology /JMS C.O.C Mumbai, February 2009
Any fluctuation of the behavior ofconventional yellow/red/blue reactivedyes (i.e sensitivity to dyeingparameters as time-temperature, lackof compatibility) leads to shadechanges that impair the results of thedyehouse.
The newly developed HUNTSMANNOVACRON NC reactive dyes allowfor a tremendous improvement ofdyehouse performances: Higherreproducibility, less seconds, costsaving and better competitiveness.

Textile EffectsResearch & Technology /JMS C.O.C Mumbai, February 2009
exhaut or continuous application has practically no influence on the shade of NOVACRON NC dyes
Consistency, Reproducibility,
Competitiveness
will consequently be tremendously improved
NOVACRON NC Dyes Benefits for the mill
• Four dimensional consistency and outstanding reproducibility
1 No tailing in the length2 No center-side shade variation in the width3 No two-sidedness in the tickness4 The same shade today, tomorow and the day after
• Increase of productivity by reducing complex processes
Textile EffectsResearch & Technology /JMS C.O.C Mumbai, February 2009
• Outstanding fastness level satisfying the most stringest customers requirements
• Suitable for subsequent enzyme/stone wash, moist cross linking/ FR/ NH3 post-preatment and post-mercerizing with minimal shade change allowing for easier shade management
• Cost saving due to much lower effluenet load (no need for sodium silicate, salt, hydrosulfite) and more efficient maintenance
