NOVACRON LS

The NOVACRON LS dyes are innovative bi-reactive dyes, with very high tinctorial strength, for hot dyeing.

Highly compatible range for a wide shade spectrum.The NOVACRON LS concept is the first and unique low salt range on the market. Only 1/3 of the salt

amount required by standard reactive dyes is needed.All these properties play a great part in the outstanding reproducibility and environmentally orientedbehavior of the NOVACRON LS dyes.

Highlights of NOVACRON LS ...and what they mean for the dyer

Outstanding ecological properties

- fixation over 80%- drastically reduced salt usage (1/3 that ofreactive dyes available on the market)

Reduced costs and worries - fulfillingsevere environmental requirements

- much less dye in waste water and- much less salt in waste water, bothresulting in lower environmental costs

- less corrosion of machinery and concrete- much less salt in water positively impactsefficiency of biological water treatmentunit

Highly concentrated dyes withhomogenous application propertiesand outstanding reproducibility

- high tinctorial strength and fixationover 80%

- drastically reduced salt usage- low sensitivity to liquor ratio variations

- excellent compatibility of the dyes inthe range, on-tone build-up and verygood levelness

High productivity, right first timedyeings

- unique reproducibility lab to bulk and bulkto bulk

- fewer corrections, fewer re-dyeings- much reduced time for handling anddissolving of salt

- automation of salt dosing facilitated- lowercosts for storage and for disposal ofpackaging material

- very deep shades feasible economicallyand ecologically

- substantial savings on cost of salt and saltstorage

- no need for highly skilled personnel

Ideal for one bath dyeing of PES/CEL(LS Superfast)

- excellent suitability, thanks to the much

reduced amount of salt and the lowsensitivity to liquor ratio variations

Minimum salt

A deep shade is to be dyed on a 1000 kg jet at liquor ratio 10:1, requiring 10000 liters water and 80 g/l salt.

The principles of salt removal

Salt removal is purely a question of dilution

It is dependent on

Carry-over from the last bath(normally 2-3 times the weight of the goods)

Amount of water (liquor ratio)(the higher the liquor ratio, the more effective the salt removal)

Soaping is most effective if the amount of salt does not exceed 1g/l. Up to now, two rinses were

necessary to remove the salt.With NOVACRON LS dyes, which require less salt for dyeing, only one rinse is normally required.This means

Time saving

Removal of salt by rinsing (liquor ratio 10:1)

Amount of salt in the rinsing baths:

The NOVACRON LS dyes give

BETTER REPRODUCIBILITY

Because they tolerate some degree of variations in liquor ratio without a marked effect on yield.

They are highly suitable for dyeing operations using more than one type of equipment or if actual

loads differ from specified loads.

Migration method

Note salt quality

Either common salt or Glaubers salt anhydrous can be used. Glaubers salt can occasionally have a marked

acid reaction. If this occurs, the amount of fixing alkali has to be increased accordingly. Sea salt and impure

common salt contain soluble alkaline earth ions.

If Glaubers salt cryst. (Na2SO4.10 H2O) is used, the amount of salt must be doubled.

Soap for 10 min at 95C/203F A second soaping operation is recommendedfor dark shades

Rinse for 10 min at 70C/158F

Rinse for 10 min cold One rinse is sufficient if liquor ratio is 10:1 oraboveRinse twice if liquor ratio is below 10:1 orgive intermittent / overflow rinse

and if required:

Aftertreat for 20 min with ALBAFIXECO/WFF at 40C/104FpH 6-7 with acetic acid

Color difference from standard original

Shade acceptability

In the illustration, shades (A, B) falling in the center ellipse (bulls eye) are not visually different from eachother.Points within the outer ellipse (C) are within trace tolerances of the standard, i.e., a trained observer wouldperceive a small shade difference (with difficulty).Points falling outside the outer ellipse (D) represent distinct and therefore unacceptable shade differencesfrom the standard.

Center point = standard (original)

Strength variations

Strength variations below 45% can hardly be perceived, even by a trained observer.

0.31 g/l

ALBAFLOW

CIRanionic


- APEO- and solvent free de-aerating agent with wettingproperties and durable antifoam properties

- instant penetration of goods, especially recommended forcirculating liquor dyeing machines

- stable in acid and alkaline media- promotes constant liquor flow, hence inside-outsidelevelness and reduced risk of channeling

ALBATEX DBCanionic

dispersingagent

Ca inactivation

- dyebath conditioner: prevents precipitation of Ca, Mg inthe water or on the textile

- promotes levelness of the dyeing and improves theappearance of the dyed goods

- binds metal ions (Fe, Cu) in the water

0.52 g/lALBATEX CO

anionic

protectivecolloid

Ca inactivation

- avoids precipitation of Ca, Mg in the water or on thetextile

- promotes levelness of the dyeing and improves theappearance of the dyed goods- keeps impurities from unpretreated cotton in stabledispersion

0.53 g/l

ALBATEX DSanionic

polymericdispersant andprotectivecolloid

- dyebath conditioner: prevents precipitation of Ca, Mg in

the water or on the textile- promotes the levelness of the dyeing and improves theappearance of the dyed goods

- binds heavy metal ions in the water



Special products


0.52 g/l

ALBAFLUID

C/CDanionic/nonionic

lubricant - reduces creasing in piece dyeing- markedly reduces textile-to-textile friction

- prevents cracks and abrasion marks- no adverse effect on the stability of the dyebath- no retarding effect

0.52 g/l

ALBAFLUID Uanionic/nonionic

lubricant - for very sensitive fabrics- prevents crack marks and creases- no adverse effect on the stability of the dyebath- no retarding effect- excellent for heavy goods

Soaping


0.52 g/lERIOPON R LIQ.anionic

washing agent - speeds up release and outward diffusion of dyehydrolysates, even in hard water- prevents renewed uptake of dye hydrolysates- inactivates water hardness ions and ensures maximumfastness properties

- low foaming

Note on all dyeing auxiliariesAmount required depends on specific conditions, e.g. type of fabric, quality of process water, type of machinery.

Aftertreatment with ALBAFIX ECO/WFF


13%

ALBAFIX ECOcationic

wet fastnessimprover

- formaldehyde-free- zinc-free- prevents migration after dyeing- protects dye/fiber bond of reactive dyes against acidhydrolysis and thermocracking

- no adverse effect on handle

13%

ALBAFIX WFFcationic

wet fastnessimprover

- formaldehyde-free- prevents migration after dyeing- protects dye/fiber bond of reactive dyes against acidhydrolysis and thermocracking

- little influence on light fastness and shade- no adverse effect on handle

Goods dyed to medium and deep shades should be aftertreated following washing off

Method: aftertreatment with ALBAFIX ECO/WFF at 40C/104F for 20-30 min. pH 67 adjusted with acetic acid. Thegoods are then hydroextracted and dried without rinsing.
