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.
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.

ANAFIX 'ME' DYES:
Procedure for Dyeing with Anafix 'ME' Brand Dyes:
Exhaust dyeing is carried out at low temperature 60-65°C. Anafix 'ME' Dyes are easily solube into water by pasting the dyestuff with cold water and thereafter dissolving it in (60°C) hot water with constant stirring:
