ANAFIX & ANAZOL Reactive Dyes
Anafix 'C', 'H' & 'P' Brand Dyestuffs (Cyanuric chloride based) are
fibre reactive dyes which form a chemical linkage with hydroxyl groups of
cellulose and thus give dyeing of very good fastness to wet treatments.
'C' Brands are applicable from cold bath while 'H' & 'P'
Brands are to be applied at temperature of about 80° C. Both these
brands suitable for dyeing and printing of cotton, viscose, cuprammonium
rayon and natural silk.
Anazol Dyestuffs (Vinyl Sulphone based reactive dyes) are suitable for
padding processes due to their high solubility even in presence of alkali.
These dyes can also be used for all conventional exhaustion methods by
addition of Glauber's/Common Salt and alkali.
Procedure for Dyeing with 'C' Brand Anafix Dyes:
Receive cold water in the dye-bath (Recommended m/l ratio 1 to 15), add
required quantity of common salt or glauber salt. Paste requisite Anafix 'C'
brand dye with water and dissolve by adding water at 45° C to the
same. Add dissolved dye to the dye bath. Enter material, at 30° C run
for 15 to 20 minutes. Add required amount of soda as (as solution), run
material for 45-60 minutes, squeeze, wash with water and soap at boil with 2
g/l soap, wash wither water and dry. Soaping treatment is highly essential
to remove unfixed dye to produce dyeing of high washing fastness.

Procedure for Dyeing with 'H' & 'P' Brand Anafix Dyes:
Take requisite quantity of water in dye-bath (recommended m/l ratio 1 to
15) heat to 40° C, add common salt or Glauber's salt, soda ash and 1
g/l of resist salt. Paste 'H' & 'P' brand colour with water and dissolve
by adding water at 80° C. Add dissolved dye to dye-bath. Enter
material, run at 40° C for 15 minutes. Raise temperature slowly to 80°
C in 40 minutes run at 80° C for 45 to 60 minutes. Squeeze, wash with
water and soap at boil with 2 g/l of soap for 10 minutes, wash and dry.
Soaping is highly essential to produce dyeing of high wash fastness.

Procedure for Dyeing with Anazol Dyes:
Take requisite quantity of dyes and salt in the dye bath at 30° C
and alkalis are added after 15-20 minutes. The bath is then heated to
recommended dyeing temperature within 20-30 minutes and goods are dyed for
60-90 minutes, depending upon the dyeing temperature.

Finally made to 1000 parts with alginate thickening or emulsion thickening.
First, urea is dissolved in water at 80° to 85°C then
dyestuff is added, stirred to dissolve. Then resist salt and thickening is
added, this is stirred to homogenous paste. Before addition of alkali this
is cooled to room temperature.
After printing goods are dried, steamed for 15-20 minutes, washed, soaped
at boil, washed and dried.
ANAFIX HE DYES:
ANAFIX HE dyes are suitable for dyeing cotton and other cellulosic
materials. These dyes possess significantly higher exhaustion and fixation
efficiency which results in appreciable cost reduction, in comparison to
conventional Reactive dyes. The high fixation and good build up are of
particular importance when dyeing polyester/cellulosic blends where liquor
to goods ratio is quite high. Due to higher fixation of Anafix HE dyes, the
drained and wash liquors after dyeing, contain much less quantity of unfixed
dyes in comparison to conventional Reactive dyes. This facilities quicker
wash off and efficient soaping.
The improved stability of Anafix HE dyes gives improved batch to batch
consistency. Exhaustion of Anafix HE dyes can be controlled by salt addition
and temperature to give level dyeing before alkali addition.
Advantage:
Excellent build up in high as well as low liquor ratios.
Not affected by wide variation in liquor ratios in dyeing yarn, loose
stock, piece and hand, in package and beam dyeing machines, knitted and
woven goods in the winch and woven piece goods on the jig.
High fixation and high tinctorial values hence economical in use.
Very good compatibility gives extensive range of shades based on few
dyes and excellent reproducibility, consistent high yields and freedom
from "listing" and "ending".
Though Anafix H/P Brand dyes do not have the same exhaust and fixation
properties as HE dyes, they can be used in mixtures with HE series.
Extretremely suitable for dyeing single bath 2 step method, cellulosic
part of polyester/cotton and polyester/viscose blends.
DYEING: Temperature 50-85°C
